What industry secret are you aware of that most people aren't?

The majority of technologies that power the internet were developed in the 80s and refined in the 90s. Everything since then is built as a layer of abstraction on top of those core technologies.

Also, the development and evolution of these open technologies relies on human interest and attention, and that attention can be diminished, even starved, by free, closed offerings.

Evil plan step 1: make a free closed alternative and make it better than everything else. Discord for chat, Facebook for forums and chat/email, etc.

Step 2: wait a few years, or a decade or more. The world will largely forget how to use the open alternatives. Instant messengers, forums, chat services, just give them a decade to die out. Privately hosted communities, either move to Facebook, pay for commercial anti-spam support, spend massive volunteer hours, or drown in spam.

Step 3: monetize your now-captive audience. What else are they going to use? Tools and apps from the 2000s?

We are facing a very real possibility of the end of the web browser as we know it. Google owns the chromium engine. Mozilla is on ever more precarious footing. It's become logistically impossible to build competing products except for tech giant. Even then everybody else gave up and went with chromium.

And Mozilla is largely funded by Google. We all just hope they don’t pull the rug from them but I have no faith that our inept, slow government would stop that from happening before it’s too late.

Almost certainly the entire reason Google is funding Mozilla is to try and stave off antitrust lawsuits.

The official reason is so that Big G is the default search engine on every install.

But that may very well just be a smokescreen.

Yep.

Google will spend more on a legal team working out how to prevent the lawsuits in the first place than they would be giving to Mozilla

But nntpd is still out there. Rebuilding Usenet will suck. But it's not impossible. Start from the net2 sites again.

Old mail RFCs included an instant message channel. I'm sure I saw code in either sendmail or uw-imap for it too.

I like the fediverse, but the old ways are still valid for their particular payload.

If you value your privacy and you have a choice between using a browser to access a service vs installing their app, use the browser.

Online services can get much more information about you through an app vs the browser. Browsers are generally locked down more. Apps in general have access to much more information from your device.

Department lead.

The website team is small, but incredibly effective. Everything works. Everything is mobile friendly, responsive, fast. It's a way better experience.

I love my app developers, but they're always behind. Not their own fault. Mobile development is complicated. There's so many screen sizes, iOS vs Android differences, platform permissions, etc.

The big reason for us to push the App on people was to get more brand awareness on the App Store. But the website is so much more better.

You literally can use it as a web app right into your phone and get a better experience.

And it'll be such a dark day when I have to dissolve the App team (and hopefully convince them into web dev)

Why not a responsive web app packaged into native viewer app? Depending on your utilization of native components of cause.

My team had the same issues you described so we build the web responsive and made that the "Apps" on the App Store + Google Play. There is still a tiny native components that hook into the web so you still need those native developers knowhow, but yes they will have to switch in large to web based development.

Less maintenance, more devs for the main product, faster progress, fewer headaches with Apple and Google tooling.

Edit: forgot to app that our customers loved that more features are available now on the "Apps" and that things work the same between devices

This is the main reason why I quit Facebook and other services. Anytime you access them from mobile via a web browser it corners you into a "download our app" page. Facebook started doing it with messenger and I knew I had to get out.

I'm not giving Zuckerberg that level of access to my data.

The interview is a vibe check first and foremost. If you vibe with the team we will overlook other things in your application. If you made it to interview, we already think you're good enough so don't stress trying to impress or apologize.

Managers are mostly people who get tired of watching other people do things badly and decide to try to do better. You don't need a special degree or any magic to be a good manager, you should like people though.

Everyone is faking it to some degree.

The „you have to like people“ part took me nearly 20 years to figure out. I hate people in general with possible remedy for people who are nice. I‘m exceptional at managing people, I just dont vibe with them. This leads to absurd situations where everyone is happy, professionally but folks just hate my guts.

So, I now work alone and am happy with it. :)

Personality, presence and confidence

Natural self confidence, but NOT an arrogant selfish confidence.

Some people naturally have confidence and presence and some people need to build it as a skill.

I know guys and gals with little to no knowledge or skill build up careers because they just knew how to talk and connect to people.

I also know guys and gals with years of education and degrees but have little to no way of politely or easily getting along with people.

Everyone is faking it to some degree.

Most valuable lesson I was ever forced to learn.

Can confirm with a very condensed anecdote: I once applied for a job that required engineering degree in electronics or mechanics. I'm a hischool dropout. Interview went well, and I got a job offer a month later. I got the impression that they were more interested in the right type of person with relevant hands-on experience, and in my case that experience meant IT/Linux (I was always a hobbyist geek)and being used to operating heavy machinery (Grew up on a farm).

I'm still in the same industry, and I earn more than my friends with masters degrees.

Former process engineer in an aluminum factory. Aluminum foil is only shiny on one side and duller on the other for process reasons, not for any "turn this part towards baking, etc" reasons.

It's just easier to double it on itself and machine it to double thickness than it is to hit single thickness precision, especially given how much more tensile strength it gives it.

Also, our QA lab did all kinds of tests on it to settle arguments. The amount of heat reflected/absorbed between the two sides is trivially small. But if you like one side better you should wrap it that way, for sure!

The amount of heat reflected/absorbed between the two sides is trivially small.

Your particular choice of wording here makes me very curious: Do you mean that there really was a measurable difference (which was trivially small)?

Yup, the lab could tell a difference! Shiney side (so mill roller facing, as opposed to the dull side which faces the other layer of aluminum) was marginally more reflective, but I believe (and a former coworker also remembered it as) it was less than a tenth of a percent (<0.1% for the visual folks)

Anyone who says it affects cooking time or something is mistaken, I'd wager.

Jokes on you.

I baked my casserole with the shiny side up and pulled it out at 59 minutes and 55 seconds, when it was supposed to go for an hour.

So take that Dull Side!

Today I learned numbers are visuals but words are not. Wtf dude!

Any info on surface roughness? I'm thinking shiny side would be smoother and therefore less sticky, though I don't know how much the passivation layer would affect it. Probably no where close to making a difference at the end of the day, but I'm curious.

It was a fair few years ago, but yeah, the oxidation on it will be so much smoother than the delta in surface roughness that I doubt it'd make much difference. Lemme reach out to a metallurgist from there and see what he thinks!

There is no financial motive for software to work well. The people who sign the check for it almost never have to use it.

That's where you need people like me who give a fuck about nothing but customer experience and if my employer manages to make a buck, good for them. My employer is generally just a middle man who siphons money out of both our pockets. And makes me fill out a second, useless timesheet while you're paying me to work.

Jokes on me though because I've been out of work for 3 months, so take my suggestion of fuck your employer with a grain of salt.

If they do a bad enough job they'll create a niche for a competitor to fill.

That's a dream. The googles and such just buy them out and shut them down. There is always a bigger fish that spends more money preserving the status quo than making a product.

True - that's a big reason I like open source software. Doesn't help with search though.

I would love to see exactly how many people dropped Adobe after the latest drama, I would bet it would look exactly like the Netflix micro dip after shutting down password sharing.

That is true for outsourcing companies, but not true for product companies usually.

I think it's equally true for product companies. Do you know how hard it is to get a company to prioritize bug fixing over feature work? Shy of a user revolt, or a friend of the CEO reporting an issue, bugs are almost always second priority or lower.

I’d say this strongly depends on the industry.

In an entertainment or ad sales product, I’d completely agree with you.

In a medical or financial product, the bug will take precedence.

Medical? Your funny. Healthcare software is the worst. There is a reason the stuff that matters is decades old. Cause the new stuff rarely works. And the rest... tell me again why I have to fill out the same forms year after year, and they never populate with my previous answers? Or why I have to tell them my 2 year old son isn't menstruating or hasn't stolen a car yet (on the same form no less). The software is so hard to use the providers have given up.

Not in my experience. Unless maybe if it causes loss of funds or other security issues, which usually get a fair response.

No idea what you are talking about. Product companies are exactly what I am referring to. Some director signs off on the purchase, probably has never even seen the software. But he has seen the sales pitch. That is what the C suite of small companies are for, mingling with the decision makers.

Found the Sonos employee.

Sonos has pissed me off. After the latest update, the app cannot locate the speakers in any of my rooms. The TV speakers still work with a signal from the TV, but the speakers in all other rooms basically cannot be used.

I've factory reset them, set them up in the app, and as soon as that is done, they disappear from the app again.

They worked fine for years, then this bullshit. I'm researching a home theater setup that doesn't use Sonos and am planning on selling it all once I've found replacements.

It feels like I don't own the very expensive hardware that I have bought. I guess since they are software controlled, I really dont.

I don't really get this point. Of course there's a financial motive for a lot of software to work well. There are many niches of software that are competitive, so there's a very clear incentive to make your product work better than the competition.

Of course there are cases in which there's a de-facto monopoly or customers are locked in to a particular offering for whatever reason, but it's not like that applies to all software.

Software just has to be good enough that people put up with it. Once you get users on the system, you make it difficult to move your data out which acts as a lock in mechanism. The company that can make a minimally usable product that people are willing to put up with will typically beat one making a really good product that takes longer to get to market.

The cost of digital advertising cannot be justified by its effectiveness (or rather lack there of). We've collectively spent hundreds of billions of dollars creating the infrastructure for invasive hyper targeted ads that do not get better results than simple billboards and terrestrial TV ads even now. We've created a global economy of marketing, media, advertising and sales solely reliant on technofeudalist overlords who've provided very little actual improvement of anything.

Maybe if those invasive highly targeted ads were the least bit accurate I would buy some shit from them. Instead half the time I can't find the product I want without wading through a sea of crap even when I give them a search with specific parameters.

(Buy Washing Machine)

“Hello, I see you bought a washing machine. Would you like to buy a few more?” - Internet Ads

For me it's been "I see you bought this specific laser engraver. Would you be interested in buying that exact model?"

No. I already bought it, and it's not a consumable. If I decided I needed a new laser a week into ownership, it wouldn't be because I was thrilled with that exact model.

Yep and in order for these companies to grow they must continue to increase the volume of ads being shown, which only makes them less effective, which they try and counter by making them ever more invasive.

Do you have additional inside knowledge?

Most people in the field don't even ask themselves this question. They all have an incentive in believing it works.

There's a book about it though: https://us.macmillan.com/books/9780374538651/subprimeattentioncrisis

Yeah it's a good book. It's a cycle that this issue surfaces every couple of years where someone does a study, finds that the numbers they're given don't match their own analysis and the ad tech platform does some PR to paper over the story.

Most people selling ads are just like the real estate agents in The Big Short. The media people make their money via rebate from the platforms by guaranteeing a certain volume of spend so they have no incentive to be putting hard questions to the platforms and the client is reliant on seeing the data which is provided by the platform with no third parties able to provide any level of transparency.

Money goes into Google, Amazon and Meta's black boxes which spit out numbers. The agency people copy and paste the figures into a presentation and everyone congratulates each other for a job well done.

Chocolate production is infested with slave labor, child labor and child slave labor.

https://www.youtube.com/watch?v=FwHMDjc7qJ8

i don't think this is a secret anymore though

I used to think that at least the parts that are Fairtrade wouldn’t be affected as much.

If I'm not mistaken Nestlé, the firm that makes various brands of chocolate, are known or at least have been known to include slavery in really poor parts of the world.

When I look at a bottle or a cuddly packaged bit of chocolate, I shudder to think the shit conditions that a person, a child even was forced or on crap pay to produce that from the cocoa farming..

Ne*tle also does this thing where they lie to mothers in 'third-world countries' (I hate that term but can't think of a better one rn) by telling them that their baby formula is better than actual milk, then give them some, which the mothers mix with dirty water, and when they can't afford the formula, they'll just give the babies plain dirty water.

An important part of that process that needs mentioning is that when the mothers are convinced by Nestle to feed their babies formula instead of their breast milk, their bodies will stop producing the milk before the baby is weaned from it.

So Nestle literally endangers babies' lives just to sell more baby formula.

Almost every neighbourhood has one. But they look like normal houses, so you can never tell unless you know where to look for.

Underground railways use houses for ventilation as well.

Building HVAC engineering (equipment sizing, ducting design, etc.) has been largely handwavy bullshit for a very long time and only recently has moved towards any sort of precision. Not uncommon to find boiler plants that are 3-4 times the maximum heating load in the winter, or fans running at 100% 24/7 when code only requires half of that.

Costs just get passed on to tenants so there was never much motivation to do better, the only reason building owners are moving now is because of government regulation and incentive programs.

I used to work in HVAC. I remember we had a small cold room that was struggling to maintain temperature, as in, design was supposed to be 0°F but it couldn't get below 36°F. There was a large hole in the box that was undoubtedly the cause of the problem, so I asked the installer how they accounted for that. "Oh, I doubled the infiltration value." When I tried calculating the actual losses it was way, way higher than the infiltration value. Like, the room needed someting like 3-4 times its total refrigeration capacity to reach target with a giant fucking hole in the box.

No idea who thought putting a giant hole in the box was a good idea.

I work in building science. It's obscene how little actual design and quality control goes into residential homes.

The typical design is just one step above being illegal, and people are often scared off of doing anything more than that by the threat of increased cost. However, they don't realize that they pay for it either way; either on their mortgage, or on utilities. Only one of those you can actually own in the end.

So how does a homeowner fix it? The duct work is already in, so is it just about choosing more wisely when replacing the furnace/ac/heat pump?

It starts early in the design process. But at that stage, it would be best to pause installation, have a mechanical engineer do the mechanical design (including equipment selection) based on an energy model and install the recommended equipment.

Technology connections did a video on this, it's actually insane how much wastage there is

Talking about energy wastage, next time you're walking around commercial buildings, pay attention to how many lights are on during the middle of the day.

Drove by a closed car lot the other day. The place has been abandoned for months. Weeds growing up everywhere. The entire lot is fenced off getting ready for demolition.
The only building on the lot is small and completely surrounded by glass walls, so you can see right through it. The red neon around the outside of the building is still on 24 hours.

condo had a fire and later I could see lights on every evening. I called it in but nothing happened. Seemed dangerous to me that power was not shutdown from going to it.

Ugh. Yup.

I learned that after buying my house. My furnace is 3x what my house needs and is expected to be an expensive repair someday.

Most of hacking is done by mass effort with maybe a couple percent of people that aren't doing basic things to protect themselves being affected. That couple of percent is enough to keep the hackers flush. (So please, follow basic cybersecurity steps, people.)

The plain truth of the matter, though, is that if a hacker or group of hackers is targeting someone individually for reasons, that person is in real trouble.

This has been a PSA for everyone chasing fame and clout.

I miss the days of Anonymous (there was a sub group of the actual hackers whose name I can't recall and a bunch of wannabes I guess providing them a crowd to lose themselves in) doing justice hacks. Not that they were always on the right side of things, but now everything is state actors trying to bring us all closer to Armageddon.

Tips for being secure online:

  1. Use your browser's password manager to generate random passwords.
  2. In the rare case you need to manually enter your password into a site or app be very suspicious and very careful.
  3. Never give personal information to someone who calls or emails you. If necessary look up the contact info of who called you yourself and call them back before divulging and details. Keep in mind that Caller ID and the From address of emails can be faked.
  4. Update software regularly. Security problems are regularly fixed.

That's really all you need. You don't even need 2FA, it is nice extra security but if you use random passwords and don't enter your passwords into phishing sites it is largely unnecessary.

Im not so sure about your number 1. Fine if otherwise they won't use one but personally I use bitwarden online for unimportant ones and a local keypass for important ones.

The reason I say browser password manager is two main reasons:

  1. It is absolutely critical that it checks the domain to prevent phishing.
  2. People already have a browser and are often logged into some sort of sync. It is a small step to use it.

So yes, if you want to use a different password manager go right ahead, as long as it checks the domain before filling the password.

What do you mean a password manager that checks the domain? Isn't the auto fill based on the domain? I can't imagine how a password manager could fill a password without checking the domain, it wouldn't know which password to fill after all. Do any actually exist?

The quality of education at college and university is in free fall.

I went to college before the internet was ever considered a valid source for any material. But using the internet made research extremely easy if I could determine the book source for reference.

I went back to college right around that time the internet just became the default source for everything. It was staggering how little information was expected to be known. The implicit ubiquitous access to information was a staggering foundational shift.

I fear too many universities are businesses designed to fund seminars; and students graduating are whether an afterthought or an actual negative for them.

It was related to me that, because they want to keep their customers, one can solve any problem at uni - grades, minor victimless crimes, etc - simply by offering to take more courses. The only problem money can't solve is the one where the student has no more money, and it's over quickly after that (saw that one happen).

It is far worse than that.

Universities have a lot of metrics that they are judged against that don't lead to a quality education. Research doesn't lead to good undergraduate students. A good pass rate just means the curriculum is soft enough to keep don't students from failing.

So you have university presidents who are incentivized to increase prestige and they aren't going to focus on the quality of education because that doesn't lead to better metrics. If presidents try to defend their universities' way of teaching, they get replaced by those who follow the system.

Most problems are being solved by turning it off and on again.

The navy manual for troubleshooting equipment in the field includes "lift 3-6 inches and drop"

Percussive maintenance can help sometimes. It's not a permanent fix but you can't always do the right fix in the middle of the ocean. Things it can help with: dislodging debris in mechanical components, reseating electrical connections that are corroding, and making yourself feel better.

To be fair, you may not always want a permanent fix for everything. Mostly because the most permanent solution will always be a temporary one. :v

What? Did I turn it off and on again? I’m a very smart technology person, of course my big brain already thought of that. I develop software for a living. It couldn’t be that simple or I wouldn’t be calling you.

Turning it off and on again worked. My shame is immense and I have wasted everybody’s time.

These aren't secrets, but may not be well known (unless you watch LPL):

Sentry Safes aren't safes, they are fire boxes with a fancy lock.

High security locks are not high security because of the lock design, but because the keys are very difficult to have duplicated.

No one (except maybe intelligence agencies) breaks in to a house by picking a lock, especially in the US. Windows, weak door frames, and, in a pinch, making a hole in the wall are all faster ways of getting in.

Car keys are so expensive because many manufacturers charge a subscription or per-use fee to access and program the keys to the ignition. These costs are passed on to consumers

No one is picking your locks just to move things around or steal small, insignificant items. You are either suffering from a mental disorder or a trusted member of the household is gaslighting you (it's not gaslighting though, you're your grasp of reality is slipping. Don't call me for a pick proof lock, just get help please)

Some manufacturers (you know, in China) will put any sticker you want on the products they produce, including UL and ANSI stickers. Before buying a product that is supposedly fire-rated, such as a fire safe, check the UL website to verify the item is actually listed with them.

"Grade 1" door hardware sold in stores like Lowe's or Home Depot is, at best, Grade 2, and is likely Grade 3 (residential grade). These grades are really just about how durable the product is over time, and how much abuse they will endure by the public.

And just a little practical advice. Find a qualified, honest locksmith before you need one. We're like plumbers. If you wait until you have an emergency to find one, the quality will be questionable. There are a lot of scammers out there. If you don't have a resource for locksmiths beyond Google, look on the ALOA website for members in your area. The good ones will know who the other good ones are, and won't be shy about sharing that info if they are unavailable or too far away

Spooks (including the domestic FBI-type ones) definitely pick locks. They also have things like spray-on dust to hide the fact they've been in a place.

I have someone like this. Glad to hear it's common-ish. She's "getting help" but the doctors can't do much more than we can.

Yeah those cases are sad. I tend to just say my prices really high, and if they persist in wanting me to come out I suddenly don't have availability because of the "big government project" I've been hired to do. Even if they were worth the trouble of all the follow-up "someone broke in, you have to fix my locks" calls that inevitably come, I couldn't in good conscience take their money.

Last time it happened a lady wanted me to install Schlage Primus deadbolts on her house because her neighbor was "breaking in and moving things to mess with me". I gave her a quote that was 5x higher than it should have been. I kid you not, she said, "Okay, but I'll have to wait a couple of weeks to get the money. My husband said I couldn't change the locks anymore and that this is all in my head." Poor lady. I saved her number so I wouldn't forget if she called again, but I never heard from her. Hopefully she got the help she needed, but probably she got divorced and is living on the streets.

They also have things like spray-on dust to hide the fact they’ve been in a place.

New excuse for when someone complains about how I haven't cleaned recently.

I learned to pick locks in my youth. I absolutely have picked my way into places and things to fuck with friends and family, but I always tell them. At some point.

One of my favorites was getting into my friend's garden shed and turning everything upside down, then a few weeks later rearranging everything so it was a mirror image of how it was previously.

If there's one thing the Lockpicking Lawyer taught me, is that the vast majority of locks only work because almost nobody bothers to learn lockpicking. Some "extra safe" locks being defeated by a fucking magnet of all things always amuse me

Sentry Safes aren't safes, they are fire boxes with a fancy lock.

Judging by the one I bought when I went off to college to keep some documents safe, they don't even have fancy locks. I misplaced my key, but I was able to open it in the same amount of time with a pumpkin carving knife as a jiggler.

Yeah that's was probably a 1200 or their document box. I was thinking of the "safes" they sell with a dial or keypad lock. They can be defeated in about the same amount of time. I won't say how, but YouTube has more than one video showing how it's done

Deviant Olam is another good one for physical security. After seeing a few of his videos on gun "safes", I looked into genuine gun safes (TRTL 30x6 or better, and/or DoD-approved weapons containers) with S&G mechanical locks, and the prices are eye watering. An S&G lock by itself ain't too bad--about $600, IIRC--but the safe body itself was $15k+, easy. ...Without shipping included, since there's no fucking way I'm getting that into my basement myself. Most gun "safes" are not even UL-listed Residential Security Containers, and you get into $2000+ for one that meets that basic, very, very minimum level of protection. (Yes, I looked in the local gun stores that carry them.) The fact that most gun "safes" aren't capable of resisting an 18" prybar that's used continuously for 15 minutes is not a pleasant thought to think about.

The fact that breaking a wall to get into the house is even a viable option honestly baffles me as a person living outside the US

A lot of the "generic" or "store brand" packaged foods are literally the same exact product as the name brands, only in different boxes/bags

I'm not so sure about food, but for many mass market products it is indeed true that the same manufacturer can be engaged to make the same product under different branding. The difference then comes down to the corners cut to meet the client's pricing. Crappier boxes, thinner bags, packing material, and quality inspection. Assuming the core ingredients are not compromised in some way.

I would like that.... Saving on a smaller package for chips and cereal sounds great, most of it is air anyways.

No you dont. I have worked in 2 groceries stores, the bags with less air get way more crushed and broken while stocking. Having bigger bags with a lot of air keeps the chips integrity in tact.

The one example I'm familiar with is a name brand ice cream company that produces the store brand ice cream too...in that case the recipe is different, cheaper ingredients to cut costs to the bare minimum. But using the machines for a higher volume saves money.

I'm sure 'same exact item' does happen too but just 'same manufacturer' doesn't mean exactly the same item.

My sister worked at a dairy for a while, they both made the name brand version of cottage cheese as well as the off brand. They made several brands of cottage cheese, so you are abolutely right that different brands of product are made in tye same factory, but depending of the brand or country it was shipped to the recipie was changed slightly based on the customer's request.

In the UK, slot machines fall into 4 main categories. Of particular interest are category C machines, as these can remember a fixed number of previous games. I.e. the "myth" that a machine is "about to pay out" because "someone lost a lot to it" can hold for these games.

Cat A and B machines are completely random, previous games can have no impact on probabilities of winning (though pots can climb).

Online games have different rules, not always fair ones!

Oh, and ALL games (in a physical location) must (by law) show "RTP" (return to player) somewhere. It usually gets stuck it in a block of text in the manual since no-one reads them. (If it's below 97.3% just go play roulette as it offers better returns).

walks into a casino Alright man, gimme the manuals to these bad boys right now, money ain't gonna win itself.

Speaking of slot machines, every slot machine, electronic poker machine, etc. are just state machines that operate based on a stream of random numbers fed into them by another device.

The random number generators (RNG’s) used for gaming are highly regulated (at least here in the US) and only a small handful of companies make them. They have to be certified for use by organizations like The Nevada Gaming Control Board. RNGs have to be secured so only NGC officials and other key people can access them. If they are opened unexpectedly or otherwise tampered with then they need to go into lockdown and stop generating numbers until an official resets it.

The RNGs also need to be able to replay sequences of numbers on demand. If the same sequence of numbers are fed into a game and the user plays the same way then the result of the game should be 100% identical each time.

A whole bunch of welds in nuclear reactors are visually inspected using cameras duct taped onto the end of incredibly long poles which also get duct taped together. This would be the inside of BWR plants near the fuel and jet pumps. There is also an "art" to moving the cameras and poles around to get the shots you need. And if you get stuck the talented people know how to get you unstuck. There are also cameras just duct taped to ropes that the camera handler "swims" to certain spots.

Don't get me wrong, we have cool ultrasonic inspecting robots as well, but I was absolutely blown away by what visual inspection looked like in practice.

PS: The high dose fields make the camera look like it is being blasted with colorful confetti because of the high energy particles bombarding the camera module.

Every high-tech workplace tapes shit together sometimes, and has systems and practices that are just kind of "good enough".

Many game companies specifically target vulnerable people, who end up spending their entire pay check every month, and are called Whales.

I'm on a game, Whiteout Survival, you've probably never heard of it. I haven't spent a penny, but I was curious about how much one obscure "upgrade" cost. Mind you, there are hundreds of purchases in the game.

It was $100 US, and it said 29,000 had been sold... in the last WEEK!

2.9 million dollars a week for NOTHING. And that's just that one obscure item, far from their biggest seller.

And that's just in one game you've never heard of.

You're a non-monetizer, just like 95% of the players. The game will make you some form of offer in order to convert you into a paying minnow, dolphin or whale. Whales are rare, less than a percent of the players, but they generate a significant amount of the revenue.

Companies compare their conversion rate with each other and have specific goals to meet. 5% for example is good. If your company has say 3%, you'll want to focus on improving that. Each product will have a specific goal here, and otherwise is shut down because there's a customer acquisition cost. Games easily cost more to market than to develop.

A lot of effort is spent on the first offer. This is where you'll see a screen that makes an amazing offer you'll seriously consider. It'll have something that is high value but incredibly cheap and so temporary. This isn't to earn money, it's simply to convert you. Because after you've spent your first dollar you're likely to keep spending.

Yeah it's been showing me that banner every time I start the game since the very beginning.

And I nope it every time.

I was suckered into the shark cards on GTA Online, I worked terrible hours and it was my escape.

I bought shark cards for thousands of SEK ocer a year or so, not much in compared to normal whales, but I did feel the addiction drawing me in harder.

Then one day I had just had enough, and uninstalled the game, else I knew I would continue.

I am glad though, the money I spent was not wasted, it taught me a valuable lesson about what to look out for, and how to recognize sinkholes like this.

It's good that you managed to wake up and take care of yourself. Players with that pattern are called dolphins.

Thank you, I do my best, I had no idea obout the dolphin name, fun!

They have ARPU targets (Average Revenue Per User) and UAC targets (User Acquisition Costs). Whales contribute significantly to the game's bottom line. Non-paying customers are vital, because player population is a game quality, and Whales need a population to notice how awesome they are.

But game companies don't tend to separate Whales from other players (at least not the ones I've worked for), they tend to care about ARPU, which is more stable, and a much easier target to shoot for. And they want to keep UAC down, which lowers the required ARPU for a successful game.

I don't know how well known this is by now, but just in case, I'll add it.

The quality of your speakers is not affected by the cable from your amp.

The connectors are more important in terms of physical contact, but almost any new connector will do. The wire itself makes no difference. Pay as much as you want but the sound will not be any different than if you used metal coat hanger wire.

Adding to this, you probably don't know how good your speakers are or not because you're listening to your room, not your speakers. If you have given zero thought to acoustic treatment where you listen to music, you definitely don't need to upgrade your audio equipment in any way. No amount of money you spend on equipment will help you enjoy music more until you treat your room

Master Handbook of Acoustics is your friend if you want to learn what to do to your room. Overkill for most, admittedly, but it contains everything you need to know.

Here's the pdf to the 4th edition.

What improvements did you make based on the book? I'm skimming through it.

I made couple of bass tramps tuned to the room’s main resonant frequencies, which I measured. I followed instructions from the book.

I added sound absorber panels to the walls and ceiling to kill immediate reflections from the main speakers plus a sprinkling of additional panels to kill reflections and also act as decoration. I also needed to move one radiator because it was in the worst possible location for my setup.

The room got thick curtains to improve absorption, and they also darken the room as it is dual use music listening and home cinema room. A few defraction elements went into the ceiling for a good measure. The ceiling is made of custom panels that I made myself from wood and fabric to allow sound energy through to the various acoustic elements behind them.

I also spent a fair amount of time with subwoofer placement, but in the end it became a bit of a compromise between sound and placement of furniture. Nothing a bit of signal processing can’t deal with, mind.

Isn't conductor diameter important to supply proper wattage?

Not quite, conductor diameter is important to supply proper current, which will change depending on the impedance of your speaker. There are other values like inductance and capacitance in a wire that could affect how your speaker sounds. The good news is that you can pretty much buy any cheap 16 ga copper speaker wire and not worry about it, as it would take effort to make a speaker wire that sounds bad (and those companies are the type to try to charge you $1000/ft for it!)

75% of American drinking water needs treatment to reduce particulate and parasites, and the treatment additive used to render the water safe is produced at a single chemical plant located in an area of severe flood risk -- which means that a flood could take it offline for a day or two, or damage it for weeks.

(Efforts to build a second site recently fell through due to ever-changing regulations. Of course they're stockpiling it in some mountain bunker, I'm sure)

The next Katrina could give us a brain-worms infestation via tap-water.

Are you saying the chemical plant provides the treatment or that one plant is somehow responsible for polluting 75% of American drinking water?

I don't know the details about alum production (assuming that is what you are referring to), but there are many alternative coagulants available now. Sure the supply logistics would be incredibly challenging and many people would have to boil their water or use point-of-use filters, but this take is pretty doomer in my opinion. Most plants use alum because it's cheap and easy, not because it's their only option.

~Things people don’t want to know~

Putting a layer of tissue between your butt and the toilet seat doesnt provide enough of a barrier against microorganisms over the time it takes to shit or piss to prevent transmission.

Keeping the air dry reduces both the length of time microorganisms can live outside your body and the length of time that vapor particles can harbor them.

The n95 (and other) rating(s) are over time in free, circulating, open air. Derate safe exposure time sharply for use inside or in spaces with stagnant or unmoving air.

How about TWO layers of tissue? Checkmate, scientists.

Signed, the toilet seat nest-builders of the world.

If you’re able to hold it long enough and you’re truly worried, folding a wet paper towel over a couple of times and using the hand soap to clean the seat and then folding it over again to get a “rinse” before you sit down is a better way to go about it.

“I’m worried about germs on the toilet seat”

“Well, they gave you paper towels, soap and running water, why not clean the motherfucker?”

“Nah, imma just put the thinnest material known to man in between my butt and the seat”

If you're going to take advice on what to use to protect your butt from a toilet seat, taking advice from bloodfart is the best option.

Most public bathroom tissue is exactly one molecule thick.

With the exception of at large buildings in dense city centers, just about everywhere else, utilities enter a building at just some point on the back, out in the open. This includes utilities that feed alarms and security cameras.

While some places will have systems in place for situations where these outside connections have been severed, like independently operated cameras on an intranet, cellular data backup for alarms, electrical generators, etc., most places don't, so successfully circumventing their security is just a matter of cutting all the cables on the back of their building at the same time, and then being gone before they notice

I'm not an expert on modern alarm systems but it seems that it is very common and fairly inexpensive to have cellular data backup. Not every system has it, but many do. In that case cutting the main connection will likely result in someone appearing on site fairly quickly.

Many cameras also have some form of local buffering. So even if you are gone before someone does show up you still may find yourself recorded.

But at the end of the day just put a bag over your head and you can be gone by the time anyone shows up without leaving a meaningful trace. Other than the very top-end system security systems just keep the honest people honest.

This is dependent on where you live though. In the Netherlands most utilities are buried under ground and enter buildings subterranean.

The company that provides your banks phone system has full access to pretty much every piece of information your bank holds on you, including call recordings, phone numbers, addresses, debts, credits, and your phone password. We can trick our own systems into thinking it’s you on the phone.

Avoid calling your bank at all costs, and if they call you say “no thank you I’ll do that online or in branch”, as soon as you pass security the phone system is accessing all your data. If possible go into branch or do everything on a banking app which has far better security.

Now tell banks to stop requiring SMS 2FA holy shit

You actually want them to do this, it’s terrifying easy to set up a cell tower or call centre and convince banks and people you are customers or banks.

I think he was meaning because of how easy it is to spoof and intercept sms. Use some thing like OTP that’s a common standard instead.

You probably mean TOTP. OTP is a generic term for any one-time-password which includes SMS-based 2FA. The other main standard is HOTP which will use a counter or challenge instead of the time as the input but this is rarely used.

The ice in your drink at the bar is very very dirty.

Not if your bartender is properly trained and not a lazy piece of shit.

I am a very well trained piece of shit.

But I am not allowed to clean the upper part of the icemachine ( where all the slime happens) because of liabillity. I do my best to keep it clean but not all of it is possible so while its one of the cleanest icemachines I have ever seen its still dirty.

And I work in a very upscale cocktailbar in a very well regulated country.

I used to work at a nice bar. It was just a side gig for "fun". I was always very careful with the ice and ice machine, because i find ice gross in general. I still found it very odd how many people just demand "questionable" ice. I'm glad if i don't get ice, please don't ice adds nothing but grossness to any drink.

Not to be judge mental here, but why do you find ice "gross"? I get it if you've seen what the machines look like, but ice in general?

All ice machines require monthly if not biweekly cleaning otherwise funky stuff starts growing in the water lines and the ice trays, and other hard to reach areas.

As a former commercial HVAC guy, consider yourself lucky if a place cleans it out once a year.

The NYPD does not internally call itself a "police force", its always "paramilitary organization" or similar.

[x] doubt

I actually worked there as an intern (unpaid of course).

Unfortunately you saying that still has the same credibility as your first statement. It's just your word. I don't doubt they do on occasion but to say ALWAYS refer to themselves that way is a lot to take on word alone.

I'm saying internally, they call themselves a police force for external (aka public) relations. Internally they feel no need to use pretty language.

Has this ever leaked out in writing or do they have 100% success rate of keeping this a secret?

Fractional-reserve banking. Most people have no idea what it is, probably a good thing. You could argue that it's not a "secret", but most people aren't aware of it regardless. I don't think most people would be fond of grinding for $15 an hour if they knew banks could just lend money they don't actually have. https://en.wikipedia.org/wiki/Fractional-reserve_banking

I didn't know what it was called, but I think it's common knowledge at this point that banks don't actually have all our money. Pretty sure we (Americans at least) found that out during the great depression when everyone was trying to withdraw their money at the same time.

And to be fair, there's stuff in place to stop bank runs now. If a bank goes under, the government takes over until it can find a buyer, so your money stays safe.

Fractional-reserve banking

That has already become outdated, at least according to some economists.
Banks can just create loans out of thin air without having to check their own reserves first.
https://en.wikipedia.org/wiki/Money_creation#Credit_theory_of_money

So if I understand correctly, the reason it's outdated is not because we don't need those pesky banking regulations any more, but that it has been found that banks will just take out their own loans to cover the reserves they need from the central bank, so they can just lend as much as they want, no seatbelts. And the central bank will never run out of loans to give, since they have insane reserves, in their own currency it is technically unlimited.

So money is not really the thing we think it is. If banks overextend themselves and fuck up, the only thing we'll see instead of failing banks is runaway inflation in the consumer and asset (housing) markets. Wonder where I've seen that.

I'm always surprised how few people know about this. The banks are literally gaining interest on money they never had. It should be illegal.

It's a little more complicated than that. Without fractional reserve banking, the economy would be more difficult to control. I would recommend a quick macroecon video or something.

I myself took quite a while to really understand why this was legal even during my macroecon credit. It actually makes sense when you think about it.

the oh so well kept secret of the software and services (surrounding it) industry that people seem to think is worth paying money for.

Yet time after time these paid software companies produce the most vile awful, dysfunctional, and garbage software (and services) that have ever been created. While somehow a group of people who aren't being paid, and aren't doing this for any sort of reason other than "why not" manage to create the most functional software ever, while also managing to somehow catch the single biggest potential software vulnerability in this decade (other than wannacry) purely because ssh has slightly sus behaviors when running the infected payload.

Please stop doing web dev, it isn't real.

I feel like most people have a feeling one way or another on this topic because it has become quite political, but the facts are the facts. Most new electric vehicle plants in the US are only working at most 50% capacity due to lack of customer demand. People can blame lack of parts and lack of workers, but one thing I know about this industry is that if people want them then they are going to keep building them regardless of circumstance.

Most people can't afford new cars, let alone new cars priced way above average.

Here's my perspective, but it might be pretty wrong:

I think the reason for the low demand is due in large part to the pre-existing gas industry, at least in the US. Not just because of marketing advertising gas-powered more, but also because people don't like to change, and buying a new car is not cheap. Not to mention that the US infrastructure is so heavily solidified in gas. It's just easier to continue buying gas-powered because it's already so supported across the country. Then the industry benefits from this because they can say, "oh, huh, looks like people still want gas-powered! ¯\_(ツ)_/¯" and so the cycle repeats.

I think a lot of people don't really understand how much power corporations really have over what the people do or don't do, like or don't like, etc.. 99% of the time people will take the easy option, and corps take advantage of that by making the easy option the cheapest and best for themselves instead of what's best for the people. Corporations only do what's right for them, and are masters of making it out to be that that's what the people want.

True. And the nepo-babies that lead these corporations are making millions off dollars each year simply by showing up to work.
Switching over to electric vehicles is inevitable. But who's going to do that work and take that risk? What if they screw up? Ain't no nepo-baby gonna screw up that cash cow. They're going to continue showing up to work every day, sucking up the income and when the end of gasoline happens, they'll throw up their hands and say, "No one could have seen that coming."

(To be fair, it's not just management. There are tons of people at every level who don't want to risk losing their job with an uncertain outcome over just showing up to work every day and doing the same job they already know. But it's the "leadership's" job to do that anyway for the long-term health of the company.)

Similarly how plastic pollution is 99% made by companies. So we banned plastic straws.

That's the equivalent of yelling at me to turn the ceiling lights off to save power, but you have the AC running 24/7 and all the windows are open.

I hate it.

At least one of the big 3 isn't meeting production demand due to battery assembly. Long series of management and integrator fuck ups where their solution seems to be just throw more engineers at it. Can't build EVs if they can't build batteries.

I would love an electric vehicle.

But we have two gasoline cars completely paid off and I can't imagine adding a car payment (or two) just to go electric. I'm more concerned with continuing to afford food and shelter.

If I could just magically swap them out I would.

Dog groomers get almost zero legal repercussions for mistreating dogs. It has to be undeniable that the groomer injured the dog on purpose before anything really happens. That's why it's SO important to trust the person grooming your dog if they're the type of breed that needs it.

Let's talk passwords. You should have a different password for every site and service, over 16 character long, without any words, or common misspellings, using capital, lowercase, number and special characters throughout. MyPassword1! is terrible. Q#$bnks)lPoVzz7e? is better. Good luck remembering them all, also change them all every 30 days, so here are my secrets.

1: write your password down somewhere, and obfuscate it. If an attacker has physical access to your desk, your password probably isn't going to help much. 2: We honestly don't expect you to follow those passwords rules. I suggest breaking your passwords down into 3 security zones. First zone, bullshit accounts. Go ahead and share this one. Use it for everything that does not have access to your money or PII (Personally Identifiable Information). Second zone, secure accounts, use this password for your money and PII accounts, only use it on trusted sites.Third, reset accounts. Any account that can reset and unlock your other accounts should have a very strong and unique password, and 2FA.

Big industry secret, your passwords can get scraped pretty easily today, 2FA is the barest level of actual security you can get. Set it up. I know it's a pain, but it's really all we've got right now.

Good luck remembering them all, also change them all every 30 days, so here are my secrets.

Password expiry hasn't been considered best practice for a long time (must be at least a decade now?) largely because of the other points you mentioned; it leads to weak easily memorable passwords written somewhere easily accessible. Even when it was considered good 30 days would have been an unusually short time.

Current advice is to change passwords whenever there's a chance it's been compromised, not on a schedule.

3 more...

Or, just use a password manager and simplify your life. Reusing any password is bad practice, even if the account doesn't seem important. Every account really should have a randomly generated unique password. A password manager solves all of these problems.

KeePassXC is such a lifesaver. Back up that local database a few safe places, and even the BS accounts got like 32 char passwords. Good for keeping notes too like "Why did I make an account here again?"

Like when healthcare or government stuff makes you have like 5 sign ups with various crappy contractors to access your basic crap lol.

4 more...

This is full of terrible advice. Password rotation is an outdated practice.

Don’t ever reuse passwords with “zones”, just use a password manager to generate long and secure passwords for every account. Then enable MFA wherever possible, and Passkeys where they have been implemented.

Then have a recovery method for the password manager stored in a secure place.

Yeah, no. Computers don't care if a password is complex or not. It can't read "words". That complexity stuff was introduced because humans think like humans, and wanted to force people to use words not easily found in a dictionary. Security is about password length, so +@#£h&1g/?!:h&£( is equally as vulnerable to a brute force attack as abcdefgh1234567 because of how modern encryption works, it I length that counts.

It is good advice to use a formula to build memorable passwords. I like a simple sentence you can type them without thinking about, as this also won't appear in a dictionary (avoid famous movie quotes, use something meaningful to you).

Fact is complex passwords created a new security risk; the written down password. Also, frequent forced password changes made it worse. Most businesses only ask staff to change passwords every 3 to 6 months these days. And web sites.never asks you to change your password.

The dirty (not so secret) secret is that, the biggest risk to security is not how complex your password is, but how easy it is to trick people into just giving away access to their accounts.

These days MFA is what makes logon credentials safer and passkeys are slowly proving that passwords themselves are not worth it for most systems.

tl;dr - complex passwords are a throwback and not better than long memorable ones like 1Verycrappycode!

All your fancy shampoos, body wash, and dish soap are exactly the same. Just different smells, colors, and water contents. Also, all mainstream brands are owned by a total of 3 companies.

Having just switched from Old Spice Swagger to SheaMoisture products I can assure you that 'different smells, colors and water contents' result in radically different outcomes in hair softness and smoothness!

Yes, no, sort of.

I mean shampoo is definitely not the same as laundry soap.

And even between shampoos, there are differences (as anyone with skin conditions can attest).

Are products in any one category largely the same? Yes. But there are differences.

I don't think this one is true. I've definitely had different brands and types of shampoo and conditioner give better and worse results for my hair.

Wash your hair with conditioner instead of shampoo. Both have detergent so they will both clean your hair, but conditioner is less harsh.

Hopefully never. I am trying to solve the problem by relieving this single point of failure, but I am not having any luck.

Worst case scenario: let's say that what I fear happens tomorrow. Given what I have seen so far, some people (regional) will notice system degradation within a week, and nationwide within one or two months. Time to find a work around is about a year, but that could be me just applying hopeful thinking to cope. I have not idea how long a permanent fix would take.

I'm smelling an awful lot of bullshit here. If the power grid (or any other major infrastructure) had a known single point of failure that would cause the entire system to collapse, there would be more than 2 people who know about it, and they certainly wouldn't be vague-booking it to Lemmy.

I'm gonna be honest, this sounds about right for 2024. Skeleton crews a dick hair away from disaster as far as the eye can see.

It's less bs than you think, still unlikely sure, but not a non zero chance.

For awhile their was a single point of failure in telcom for the midwest in the us. Because the core router was so old and didn't play well with failover. It took them several months and a lot of intermittent issues to get it replaced and working as expected.
