In Linux, the actual cost of the call to create the thread vs the process is negligible (its actually just flags to same function, saying whether to share the address space or COW it).

But then the cost of starting to use the process introduces a second speedbump, because once you start exercising it you start COWing things.

There's also the cost of task switching. I don't know the details, but I wonder if modern side-channel mitigations in kernels flush a lot of stuff when switching processes that they don't need to do for threads?

Postgres uses a lot of shared memory to communicate between the processes, so its really its own implementation of threads. Postgres is how it is because its history and portability from a time before threads.

In any case, if you were starting out today you really ought have a few threads that are shared and use async processing and plenty of io_uring. Modern Linux allows massively better mechanical sympathy but all the big database engines are already written and can't shift their paradigms so easily. This is from 2010 about how to massively speed up databases with syscall batching (in this case, MySQL is used in the study): https://www.usenix.org/legacy/events/osdi10/tech/full_papers...

The thing is: you paid for your bedroom ceiling, your bathroom and your car. You also paid for your computer & screen, but you did not pay for the content you're watching on it.

I am entirely with you on not wishing any ads at all, anywhere. I just think that it's not realistic to remove ads entirely on the open web today.

This should not be an excuse for the way ads are being run today. It is fundamentally broken. Incentives and attributions should be changed.

Ask HN: How do you create your own meme coin?
So, we’ve all heard of Doge and Shiba Inu, and my wife and I have decided that we want to create our own memecoin. This is just for personal use, no actual monetary value.

But I haven’t been able to find much documentation on how to do this sort of thing, or links to sites or services that can make this happen.

Which also leads me to believe that maybe we could start up a business helping others to do this sort of thing?

Anyway, what sites or resources am I missing?
I think FLOSS people ought to disagree with you.

Also, this very site has no ads. Neither does wikipedia. Nor librivox, or Project Gutemberg...

Tracking people almost always a bad idea in my opinion.

Even if they get something in return like early access to something.

Even if they're happy to accept being tracked.

There just isn't a good justification for it in most cases. For a start, most sites that track users don't even use the data they gather. They're just gathering it because they're think they're expected to. So many sites implement Google Analytics, Hotjar, etc and then use the data as nothing more than a web counter. That's beyond infuriating to anyone who thinks privacy is worth fighting for. If you're going to violate my privacy, at least do it for a good reason.

In the case of the article there could be solid reasons for hoovering up lots of information about users. But really, unless you're in a massive company with significant resources, all of that perf data is just going to sit in a database and a senior might occasionally look at the dashboard overview and think "We should make our images smaller." or "Huh, users have a sucky time when they're on Android. Oh well.". Those are not good reasons to gather real-world user data instead of relying on Lighthouse scores. Lighthouse is "good enough" for most people.

I imagine that a frustrating part of working on web perf is that small companies and startups don't have the resources to do it well, so they end up cargo-culting what Google does but without spending time or effort to make good on what they might learn.

To be fair to the author, I'm much more at fault here than they are. I have no doubt that the article is aimed it at a much smaller audience (the web perf community), and now I'm here saying it's not applicable in a much broader context because it was posted to HN. I apologize to them for that. This is something I care about and it was an opportunity to rant. :)

This article seems to spawn many threads on online advertising, but the initial comment from the author seems to be more around a system/architecture issue (i.e. why should a browser require backend servers). I am writing this comment here to see what people think about this question specifically.

Better question: how long does it take to debug such code?
You can turn them off basically except their "rapid release" releases - and even then, you can get unbranded Mozilla-compiled builds that can unlock the functionality (on desktop).

Google has something to do why the Android Firefox is crippled: before Firefox 68 was released, the Google reviewers actually rejected it owing to the addons system. (Yes, I know Kiwi browser exists. I don't understand the reviewers' logic but here we are.) Fortunately, FF 68 is an ESR release and was able to stop-gap the issue by releasing security updates (which aren't blocked by Google). Unfortunately, this is the reason Mozilla is only shipping "recommended addons": Mozilla has individually reviewed it because Google will penalise Mozilla if there's a malicious addon on their store. (Note that I won't shield Mozilla on the "Daylight" updates: I hope that they just continue Fennec rather than they rewrite it but personally it's fine.)
I only have the untrained DBA perspective coming from building and hosting MySQL, Maria DB and postgres clusters over the last 14 years and I feel that Galera clustering feels a lot better than anything I've seen in postgres.

Agreed that postgres has amazing performance. I was actually an early convert to postgres back in 2004 because my boss and coworker at the time saved entire businesses by migrating them to postgres when they had enough of trying to scale MySQL with more hardware vertically.

But in the later decade when I myself have used clustering to scale I've found that Galera feels less like a tacked on afterthought than anything I've seen in the postgres world.

It's just a lot more integrated than pgoool and watchdog.

I know there are new solutions now that run the postgres clusters inside kubernetes that I haven't tried yet. But that isn't more integration, that's just more 3rd party abstraction.

Edit: I realize after I wrote this how strange it must seem to a developer. Because galera/wsrep is actually a 3rd party replication product "tacked on" to MariaDB. While postgres replication, afaik, is written into their mainline code. I guess my gripe wasn't about the replication but rather the "clustering" around it, like maxscale/haproxy/pgpool and so forth. And in that sense they seem pretty equal, I just chose to use pgpool for my postgres clusters and that is definitely a hacky, scripty mess compared to HAproxy or Maxscale.
Oh, there's worse. Some video chat apps encode in software. The magical browser APIs don't always give you enough control to do what you want with the video stream, so they just output the video stream into a hidden canvas, screenshot the canvas 20 times a second, and throw the frames at ffmpeg.js ...
Very very cool and ambitious, it's always instructive (and somewhat scary) to see people mixing looking at the actual integrated circuit with low-level programming and spaghetti-style wiring to get information about.

Anyway, not sure I understood the issue right, but shouldn't it be possible to at least get a decent approximation of the suspected color-mapping by just writing a program to display all 512 possible colors (it's 3-bit RGB) on screen, digitizing 1,000 frames of "pure" RGB output along with 1,000 frames of YUV, and comparing?
Not true. WhatsApp uses the same E2E encryption as Signal.

The only place it doesn't use it, is when you are talking to WhatsApp Business users, as the business API needs access to the messages.
I used gadgetbridge initially but ended up switching to "Notify for Me", which is a lot more hseful. It's written by an individual in Italy but is still closed source and phones home, so I use NetGuard and LineageOS to block all network traffic to the app. It still works fine.

I don't use most functionality, but steps, sleep time, heart rate, and notifications/alarms have all been useful to me.
You can disable video and sound autoplay in Firefox. But anyway I try to avoid those kind of websites.

Online ads benefit the little guy. Nike and others can afford billboard and TV ads. If you've ever tried starting up a small Shopify business, online ads are all you're going to get.

The problems are the power Facebook and Google have over the ad market, that increases ad costs for businesses by a lot (I've read, one third, but I wouldn't be surprised if it's more). But online ads are a lifeline for small businesses. Regulate the big players, and keep the ads flowing. Some people here want ads to be abolished, but you'd just strengthen existing brands, i.e. huge multinationals. That's all it would achieve.

That's why real issue with Brave, frankly. I still use Brave as my default browser because it's the only one that allows me to allow all ads by default, and only turn on Brave Shields for specific websites. Even uBlock Origin deprecated their default-allow, and it now breaks many websites completely if you try it. But I don't like "anti-ad" sentiment.

Sad state of affairs. But people who oppose Big Tech domination, and also want ads abolished, don't realize that doing so would prevent millions of small businesses from getting off the ground. Chrome's killing the open web, but might be saving the "open economy" by trying to disincentivize adblocking (by blocking "annoying ads" by default, and implementing ManifestV3). It's a mess.
That feels like an issue to be solved by the tests. If a program conforms to the public test suite the program "works" or the tests aren't covering the specification.

It isn't within the party line to support encryption any longer, because there are no conservatives in government.
I was a CFTC consultant for a time analysing suspect code subpoenaed in an investigation. I can say that the parameters for analysis were very strict and required explicit proof of spoofing by the app involved. The people I was involved with were definitely not ghost hunters. They took their role very seriously and were not looking to bust someone who wasn't being intentionally manipulative.

I'm sure there are other anecdotes, but it left me feeling like at least this government org was doing what it was supposed to.

Day traders mostly don't even have access to real-time L2 market data, so they mostly can't be harmed by spoofing.

The harmed parties are algorithmic traders that use L2 market data to adjust their theoretical value.

SaaS Presale – Opportunity or Scam?
Guys, have you ever heard about successful SaaS presale? I've read some articles about it and comparisons to Tesla's Cybertruck (duh), but there was never any serious scale involved, more like a dozen seats sold. What would encourage you personally to invest like this? Is it lifetime access or money back guarantee? What is the max price that you'll pay for MarTech tool on a presale terms?
Thank you for all of your feedback in advance! :)
An inspectable and reliable dry run option and/or an interactive confirmation would solve some of these problems.

How to reduce the time complexity of nested loops
Is it really surprising that he’s only looking at Chromium based browsers? The trigger that ultimately caused him to drop Brave was being unable to use an extension from the Chrome Web Store. Switching to Firefox doesn’t fix that.
I am still using Brave, but I am immensely bothered by them forcing us into using their own wallets (out of deals they make, None uses Uphold! except forced by Brave) instead of any decentralized option.

Then constant bugs when paying out BAT rewards, causing you to lose them, but never refunds you.

This thread is full of people suggesting to just switch everyone, including grandma, to Signal/Matrix/Telegram/XMPP.

This is naive.

First of all, I'm a big fan of Signal and Matrix, but it is hard to overstate how much more polished WhatsApp is in comparison. There's just a lot more friction for grandma. There are also considerably fewer resources behind the alternatives, so things like this [0] happen (tl;dr - it took Signal over seven months to fix a bug in the Android client that would sometimes send messages to the wrong person!!)

Second, the problem doesn't end with grandma. It's the network. There are literally billions of people on WhatsApp and there are places where WhatsApp is the default method of communication for everything. Schools and kindergartens use it for announcements and to communicate with parents. Service providers give out a WhatsApp number to contact support. Friends and family are all on WhatsApp in established groups with a long history that everyone wants to keep. Trying to switch everyone over is futile. Not being on WhatsApp isn't an option. It is that big.

I joined a few orgs fighting for a systemic change, understanding the decisions process and be a part of it, more collective life in support of all the discriminated people and a more ecological way of life. Left-leaning stuff.

All the public communication happens on Facebook, Twitter and Instagram. Private comms are on whatever those platforms have, or Telegram and Discord. Only a minority have Signal and most don't want to hear about it.

When I tell them there's an internal issue because you can't change the world and give more power to the people by using anti-users tools like those, they look at me like I'm from another planet. There's a long road ahead.

Obviously we have to take the linked comment at face value.
I believe that given that one knows the user agents of users, it is possible to create a test suite with browser automation tools to measure performance in some interactive scenarios in different browsers. It's still 'lab data', but not as crude as just time-to-first-render or whatever you can measure without considering user actions.
I doubt the difference with real data will matter at this point. Am I wrong?

Is "continuous discovery" really needed? Maybe I'm naive, but can't a product - or a business - just be "done"? Nothing more to do but be a great product or service to someone. With happy, well-paid employees. A good reputation and a great place to work.

At $dayjob I often feel as though upper management are just "playing business" the way a group of school children would. Going through motions with no real care for the outcome. Sometimes you win, sometimes you lose. Is it almost holiday time yet? Gee, we might not hit budget this year. That's ok. Next year we'll add 20% and see what happens. Shall we go on a hiring spree? Nah, let's shut down building C and move those people into production or marketing. Half will quit on their own. And so on.

Maybe I just don't see the point of the hamster wheel of features.
