For a somewhat simplistic explanation, RHEL became very successful as a tool to replace proprietary RISC Unix servers (often running Oracle DB) with x86(-64) and Linux, offering a traditional "enterprise" support model those proprietary UNIX customers were used to. So what has changed?

1. The above market is pretty much "saturated" in the sense there aren't many proprietary UNIX systems left to convert to x86+RHEL. So not much growth potential there.

2. Oracle has their own RHEL rebuild that they aggressively(?) market to Oracle customers. And I guess it makes sense if you have a server to run Oracle DB on, to also use the Oracle RHEL rebuild to avoid the situation where you have a problem and Oracle and Redhat point fingers at each other and nobody takes charge of solving the issue.

3. Cloud. Cloud is obviously big these days, and it seems for one or another reason cloud deployments often choose some other distro than RHEL, be it one of the free rebuilds (CentOS, Alma, Rocky, OEL), or something else entirely like Ubuntu.

While I'm not privy to any RH internal info, it wouldn't surprise me if they're worried about the above trends continuing. Whether this recent change to make life for rebuilds a bit harder will materially affect anything, and if so how, remains to be seen.
I've implemented an email service using wildduck (https://get.bantumail.com). It works great, and the storage architecture is great, but I'm afraid it will cost a lot with scale, because I do not want to manage a large, business critical mongo cluster that stores attachments. I'd rather store these in object storage and have messages in postgres, so I'm considering implementing that for wildduck. But for your use case (family and friends), wd is a great choice.
Eric Ries with his Long Term Stock Exchange for me really nailed this issue. HFT is the epitome of all the reasons why the LTSE is great.
Yeah, I'm finding that I also need to understand authentication well enough that I COULD implement it, just to safely and correctly use someone else's implementation.
China? Grass paint is booming business in SoCal. All because they don't realize they live in a desert. People bash on Arizona for spending water when it's super dry but take a look at Southern AZ lawns vs SoCal lawns. The Southern AZ ones are much more adept to the desert.
This gives them an advantage in the supply of material for fecal microbiota transplant bacteriotherapy. Unless they use the proceeds to stop eating like hunger-gatherers, which seems to be the usual path.

I know some modern Californians who eat like hunter-gatherers. I wonder if they might be able to monetize their gut flora.
Over 100 years I would expect 2 failures to overlap multiple times especially if you are willing to let one slide.. I'd have to assume they were getting paged when it failed and they failed to set a new bound to resume paging for a worse failure. Anything else could have been their second failure that caused an unacceptable temperature change instead of a cleaner misreading a breaker panel that apparently only needed one failure per 25 years.

Not the most scientific cleaners meet not the sharpest planners.

Isn't that trivial to at least mitigate via time-of-use rates?
On a related note, there's a proposal for a Unicode project to improve complex script support in terminals: https://www.unicode.org/L2/L2023/23107-terminal-suppt.pdf

Many layout and shaping issues are present even in monospace text, at least if you want to do anything beyond ASCII.
One counterpoint to this is Lisbon, with its unregulated building codes. If you’ve shoulder barged a doorway that’s too narrow, looked out of a window that’s one third obscured by a brick wall, or sat on the can and had your knees hit the walls, you’ll know what I mean.

Planning and standards aren’t quite the same thing, but unregulated building has negative consequences on quality if not quantity. Does terrible Portuguese architecture go hand in hand with an abundance of affordable housing?
Wasted opportunity - could've been a top tier SaaS hustler with that perfect playbook.
The first thing I saw of Titan, while lookong for some footage of the infamous controller, was two screenholders, and that lightbar fr AliExpress or something, directly screwed into the inside of the hull... I honestely do not know what to say about all of this, which is actually pretty rare.

Politicians don't sign any NDAs to get their clearances; they have a separate process.

This is why they're so willing to leak things as they don't actually suffer any repercussions (besides electability).
The problem isn't Red Hat getting them, the problem is a Rocky "customer" would have to just wait for Red Hat to release the patch and then wait for rocky to re-build, and re release.
Absolutely. Just like the fact that companies will make as much profit as they can get away with - they will treat their workers with as much, or near to as much as they can get away with.
Pretty much what I was going to say. It also helps that books have fairly direct "runtimes" that don't get depreciated on an regular basis. Eking meaning out of a 60 year old book is simple - running a 60 year old program is a goddamn nightmare.
> There was a time, not too long ago, that Red Hat found value in the work done by rebuilders like CentOS. We pushed our SRPMs out to git.centos.org in a neat package that made them easy to rebuild; we even de-branded it for them. More recently, we have determined that there isn’t value in having a downstream rebuilder.

> The generally accepted position that these free rebuilds are just funnels churning out RHEL experts and turning into sales just isn’t reality. I wish we lived in that world, but it’s not how it actually plays out. Instead, we’ve found a group of users, many of whom belong to large or very large IT organizations, that want the stability, lifecycle and hardware ecosystem of RHEL without having to actually support the maintainers, engineers, writers, and many more roles that create it. These users also have decided not to use one of the many other Linux distributions.

This is a very important section a lot of the comments aren't mentioning.

It seems the potential loss of new user flow for them is worth it, as the majority are just using it as a way to avoid paying for RHEL, which was never a free product.

> The CentOS Stream gitlab source is where we build RHEL releases, in the open for all to see.

So there shouldn't be *any difference* between this repo and the final RHEL binaries right?, at least on tags/releases.

But what about unplanned security patches, are these also built in the CentOS stream repos?
RHEL was only used & adopted because everyday people could use it. Then when they had jobs at their enterprise, they could bring what they knew with them.

If RHEL is only for paying people, as McGrath from the pulpit so expounds, most people are gonna leave. The value was having a community, a good path, that extended from open source to paid support. If McGrath blows up one end of the continuum, the other end will certainly wither collapse & die. This is a deathmark. People are upset to see a vibrant world shut off and thus shut down, whatever the value/greed/whatever of the situation. A pillar of Linux has left the chat.
I don’t understand your parenthetical reference - paella and patella are very different things…

In any case, I took Paella to be a play on infusion (used in making Paella vs diffusion.

Or maybe these guys just really like rice.
We're at a point in time where it's more accepted than ever to speak a different language at home than the lingua franca, with more resources than ever to help one to learn a second (or third...) language. Yet I see these kinds of articles at least once every six months. I relearned my "native" language after a skip of two generations, these folks can do the same.
Prices going up and things costing more are synonymous. This is textbook inflation. Policy makers have to look at things from different angles. Central banks really can't do much of anything about structural problems. They can only raise or lower rates. They will put some weight on the distinction of core prices and volatile ones, but really they don't have any levers to affect profits or wages directly.

That job goes to legislators and even then, they don't always have clear options. Windfall profits tax is a start, but what they do with the profits they collect is another. No one likes price controls, but taking short-term action or maybe enacting price stabilization could be very effective. And, of course, all legislation becomes a political minefield where vocal contingencies will simply disavow empirical evidence in favor of pushing an agenda.

I'd also caution against laying too much at the feet of "corporations". Absolutely anybody selling anything on the open market will be doing the same thing. Most homes are sold peer to peer and home prices are inflating like crazy. I wouldn't expect any rational home owner to sell their house for less than the maximum price they could extract because they think buyers deserve a break.
What's the actual harm of HFT for the average person? I can set a $ limit on my orders, so I don't pay more than I want. Why should I care if some HFT guy scrapes 0.01% value off each trade?
This is an ancient form of exploit that was (and maybe still is) very popular with Windows: from the ctrl+alt+delete lock screen, you could open things like Help and accomplish similar actions, eventually getting access to a browser (which, in Windows' case, was also ~Windows Explorer with full file system access).
>The poorest in America are continuing to have children; their lifestyle isn't encumbered by a family.

And those kids most often have all sorts of problems when they grow up. Sure, my poor as fuck mom could raise us, and technically keep some food in our mouths, but the stress of doing so while having an anxiety disorder that the back asswards rural community we lived in didn't even know existed until 2010 basically broke her. Thankfully we were predisposed to intelligence by genetics, and a strong family value of education, so the kids all "made it", by varying degrees.

Each and every one of us is in therapy, and on multiple medications. How much does that cost society over a lifetime? How much would it have cost society to just give my mom a little help to raise us instead? Helping poor families not drive themselves crazy struggling to do the basic things of being alive has a huge potential upside, and it's abhorrent that we don't do it because some people think they don't DESERVE help.
If you go to see them in person it becomes clear why. The jungle foliage in this region is so thick that you could be standing 2 feet away from an ancient pyramid and not even realize that’s what you’re looking at. Besides that the area is very hot, difficult to navigate, and not particularly safe (full of narcos and rebel groups)
The sad part is that much of what makes programming hard is the fault of programmers (primarily the endless churn, but others too).

Comparison to modern-day IT trends: only allowing a "Platform/Ops/IT Team" to do certain things for users. Wait for someone else to do something you could have done yourself if it wasn't for bureaucracy and a jobs program.
> People would ask "isn't immutable data expensive to reclaim and allocate". And his reply was always that the JVM's GC was just that good that the benefits to be gained from immutable data outweighed the marginal performance penalty of the amount of garbage collected. What changed since the old lisp days? Well we now have GCs that are super fast and JITs that can optimize dynamic code well.

It's a little odd to see this deeply mistaken belief dating back to the early Java days being advocated for today. GCs are very constrained by the tradeoffs they make, there's no free lunch.

Much in the way an F1 car is only fast on a race track specifically made for it, the only reason a massive rate of allocations can have a merely marginal performance penalty is if the GCs in question have been specifically designed to handle it. But in doing so, they must have made sacrifices elsewhere, e.g. to memory usage.

Code that's not written with the underlying machine that will ultimately execute it in mind will never be fast, no matter how much we jiggle tradeoffs around. Therefore, while the gains of immutable structures may still outweigh the performance loss, the loss cannot possibly be characterized as marginal.
Tangentially related, is it worth it to do the leetcode grind and all the FAANG-interview preparations if I'm always planning on working remote? Are there remote companies with FAANG-level compensation that would warrant this sort of interview prep?

I think the problem for the writer is they cannot say their name in the native accent.

Most target date mutual funds have some REIT exposure but it's limited and overall they are more broadly diversified than most managed pension funds. The risk with target date funds is very low, and if one worker makes a bad 401(k) investment selection it doesn't impact other workers. So defined contribution plans are more resilient overall and less likely to suffer catastrophic failures.

Capacitive touch sensors aren't horribly complex. I'm betting this is something you could learn about and implement in a fairly short amount of time (6 months with zero electronics knowledge?).
Do these numbers make any sense unless they are put in perspective of "deaths as a percentage of population" ?
1. Politicians and the bureaucratic class have deep investments in real estate

2. Foreign money keeps flooding into western economies to find a safe haven and lack of capital controls. A bulk of it goes into real estate.

3. Elections are largely monopolized by older people who mostly tend to be homeowners.

The entire system is rigged against anything that would impact home prices - such as an increase in supply or change in zoning laws. Entire countries seem to be perfectly okay with watching its young people be priced out of cities and areas they work in as long as "number go up".

All the hand-wringing about political gridlock is just a cover for basic greed. Detestable.
Unveiling DeepFakes: An MIT Initiative to Counteract AI-Manipulated Videos
Back in my day we would run laps around the school webmaster and their site blocking. Eventually they gave up when they realized there were more proxy sites available for us kids to find than time they had to go through the logs and block this stuff on top of their usual IT workload for the week. At some point we also realized you could proxy a website with google translate, and that basically became as good as gold in terms of an unblockable proxy, because kids needed that website for language classes.
Many of the leading Linux users are never going to pay for RHEL.

That includes expert users who don't need enterprise support. If you make them use something else, then that will become the most battle-tested enterprise distribution.

It also includes developers. If they run on your platform, then it will get native support. If you make it easy for them to test on your platform, then it will get first-class support. If you make it difficult and they feel like second-class citizens, you will get no support.

Open source is about community, and RedHat has made it clear that the only community they care about is companies willing to pay for expensive per-server licenses.

With the rise of the cloud and containerized workloads, the business model of providing long-term support for on-prem servers is declining, and they are just milking the customers who remain.
That number could do with more details on how that number was counted. Apart from provisional permission (which still a lot of further planning effort), I know from bitter experience that a "granted" full permission does not actually mean you can build there yet. It's also possible for duplicate grants where only one of the permitted options can actually be built. It would need to count the number of houses which have been granted full permission and for which all pre-commencement conditions have been discharged. (Also, if the article is right and the number of applications has been increasing over time, it could well be that the majority of the not-(yet)-built houses are in the more recent batch).
There's certain to be natal/genetic/etc differences in the kids, though. (Are infants put up for adoption more likely to have been born to mothers who are in poverty? Who smoke, drink or use drugs? Who are younger or older? Does IVF itself have positive or negative effects? Etc)

Really the ideal test would be, in order of preference:

1. randomization (some parents get the classes, some do not, chosen randomly)

2. geographic (parents in state/area A get classes, rest do not)

3. temporal (parents after year X get classes)

4. twins (parents of twin A get classes, twin B do not)
Don't deliver mail to a London recipient if it is midnight in London. If it's noon on a weekday for another recipient, go ahead and deliver it to them. Also, there would be no need to have restrictions on sending -- email is store-and-forward already. Send all you want, it will get delivered when the receiving party is available.

These used to be the default expectations around email: your recipient will see it during business hours, when they next dial in. Broadband and always-on internet creeped up without us really examining this, so Outlook is now just a chat client with a weird UI.
Related, I used to root my old android phones by going to rooting websites that would do it all in browser.
I appreciate you feel strongly about this but there's no need to resort to insults. I've never suggested that you're the problem, just that I'm troubled by the offhanded way you dismissed a whole avenue of exploration.

One thing I will say is that whilst some social attitudes are improving, society hasn't come very far in fundamentally challenging the norms and prejudices it hoists on men and women. In England and Wales, 1 in 4 women have been raped or sexually assaulted. Literally a quarter. I know that as men we our own unique set of issues, such as high rates of suicide and substance abuse. But I look at that statistic and am concerned at what it says about the safety of women in society.
I would happily code and run a lottery system for $0.99 per entry. Someone else would likely do it for cheaper than that.

I skimmed this briefly but I can't reiterate enough the importance of practice that the author mentions.

I am the same person when a FAANG hired me as I was 15 years prior when I first interviewed there (I also interviewed a bunch of times in between, for successively more senior roles and did better in the process each time.)

When I was young, I had some fixed mindset - I am either good enough or not. They will either see that I am good or they won't. Nowadays, it's obvious to me that it's my responsibility to make it easy for them to see that I am good. That's what practice is - it's you working on your ability to articulate your fit for the role. That could be your ability to solve problems at the whiteboard, honing your career story, etc - the point is that if you ultimately don't have something to offer, no amount of practice will help - but if you have the potential but don't know how to let it show, you won't get the job either.

I imagine a FAANG salary allowing fully remote would be a very competitive position.
This is anecdotal but the same exact thing (albeit with an Apple Watch vs. Android) happened to me a few days ago- I had forgotten to turn on the watch's water mode before going in the water. After about like 5 minutes in the pool it started calling 911 for a medical emergency. My watch ended up calling 911 about 3 times (it probably tried to call them about 5 more times but I ended up taking it off in time to prevent those calls- since it wasn't responding to my inputs at all). I also got a call from the Sheriff's office a little bit later and had to sheepishly explain that my watch was spam calling 911.

Still unsure what happened with it exactly, but whatever was triggering it to do this seemed to not simply be due to water on the screen since it tried to call 911 again even when I put the watch back on hours later after it had dried. I have since power cycled it a few times and let it run out of battery and it hasn't tried getting me arrested for spoof calling 911 again, so that's promising.
I have a suspicion that at some point, an HFT group will obtain a brief but substantial lead in machine learning (a la RenTech, but on a shorter timeframe) that allows them to suck a decent amount of money out of the stock market before anyone else can respond or close the gap. We probably won’t get any sort of regulation until after that happens.
In a healthy market, HFTs serve as market makers, and allow normal traders to have faith that prices will be consistent at all exchanges. If there is enough competition, an HFT will have very low profit.
There are a ton of remote roles at every FAANG too. If you are good and they want you, you can negotiate for those.

Being able to interview and get good offers helps your story. Even if your story ends up using those offers as leverage elsewhere.
