I imaged Windows 95 and 98 PCs using "udpcast" from bootable Linux floppies back in the late 90s. I can't remember the kernel version now, but I remember that it was really nice when "make bzImage" was introduced. The kernel be stored bzip2-compressed. As I recall I got a few more KB file files in my root filesystem after that feature was introduced.

It's amazing how much comes back just researching for this comment-- fond memories of manipulating "root flags" with "rdev", for example. Knowing exactly what was going on, from BIOS handing off the boot sector thru the kernel starting up and mounting the root filesytem was a real treat.

Dealing with the unreliability of floppy disks and floppy drives, however, I will never feel nostalgia for.
Same here, sure there are downsides as mentioned above, but the interaction creates a strong human connection that is just not there when working remotely.

Keep in mind that this article was written by a reporter who was unable to talk to the district, and got all their information from a lawyer representing the kid who was suspended. The district itself is prohibited from releasing any information about the case by privacy laws, no matter what the family says or how accurate it is. The same evidence was presented to the school board in an appeal hearing, and they (granted, probably not technical people) did not find it convincing. That doesn't mean the family's lawyer is wrong, but it is worth keeping in mind as you evaluate this. We don't have the whole story here.

Yes, I agree that the block is dumb. No, knowing that technically it’s useless made no difference whatsoever in getting them to lift it. There is no financial incentive for them to improve their block to be more capable or granular. They would rather not have customers who use a VPN, because to them a higher percentage of those customers are abusive. What case might you recommend to convince them otherwise?
I mean, there are funds who are putting billions of dollars into defi strategies.

Yields at the moment are crushed, but during the hayday you could make insane money.

Almost all crypto trading firms have some sort of defi yield farming presence, and many tradfi firms were thinking about entering the space. Whether they still will and if yields will recover is still an open question.

There are definitely some dapps that are pretty solid imo: uniswap, aave, maker, curve, and alchemix to name a few.

Whether it's all a scam is a good question, but from my perspective it doesn't really matter. The goal is to make money by being smarter than everyone else.

I don't think I'm making the world a better place or really helping anyone besides myself/firm, but that's okay.

Some people think finance is perverse because it attracts tons of top talent and utilizes their skills for a dubious purpose. While this may be true, it's also true of many other industries as well: most notably, big tech. Ultimately, people rarely make employment decisions by thinking of how many people they can help.
No make use of the Proper Data Sets that the Atmospheric Scientists make use of and research there that has to Pass Peer Review and Joe Bastardi has the proper Credentials there and his view more than matches your view point so look at his statements but he's not specializing Climate Research as his specificity in his Atmospheric Sciences background. But ask him about ACE and how relevant that data set is there along with Terabytes of other Data from the Remote Sensing Weather/Atmospheric satellites that the Climate Researchers have poured over for there related research into the matter!

There is also plenty of Aviation Related Atmospheric data sets that go back further on the weather readings from Aircraft that get automatically recorded and fed into the weather modeling data sets and that info goes back further as does the Atmospheric weather balloons and those soundings!

You did a good job with the limited statistics of your extremely limited sampling of the Atmospheric Historical record but that limited sampling lacks any finer granularity there compared to what the professionals have worked through in their research.

And in no way should anyone not go back as far as possible for any datasets including tree rings and other indirect methods of sampling further back in the historical records there. And where did I actually say that one should not go back as far as possible for as much data as possible. I just stated that the datasets get less detailed the further back one goes but that still comprises more data than you have made use of to come to your conclusion!
The luck could come into play by getting questions on the test that he was prepared to answer. For example, in 2014 I worked at a FAANG, and was applying to another FAANG. I had a co-worker who was the same level as me who also applied to the same company, and bombed the interview. However, I knew from extreme first-hand experience that this coworker was a better engineer than I was by far. But it just so happened that I got lucky with the questions I got, where they all fell into my wheelhouse, and he got unlucky. I got the job - he didn't. I consider that luck on my part.

In retrospect, maybe he did get lucky and I got unlucky, since his stock has outperformed my stock by 3x over that time range.
"The next series is the time to fix your mistakes from this one".

No matter what, startups break as they grow. You will need to fix things. Just make sure they're not sooo bad that you can't do it in a timely/affordable way.
If things could be "consigned to history" by C++ adding more features, there'd hardly be any other languages left! It has all the features. That's its biggest problem.
>PoW is a beast that consumes everything it can.

It doesn't really "consume everything it can" like a paperclip optimizer would. Like you said the reward for mining is fixed, so the amount of money/resources it can consume is limited to (mining reward * bitcoin price).
> Practically speaking the data model creates very little value.

That can be said about any cost centre, but you don’t have to drag managers kicking and screaming to get them to buy fire insurance.

Practically what it does is allow the company to keep up velocity and not be distracted putting out fires everywhere.

Of course building features is the team’s entire reason for existing. But there is no advantage to defer refactoring to some later date. The longer you wait the more painful it gets.

Chances are the time never comes, once progress stalls and the company isn’t out of business yet someone will have the brilliant idea to rewrite everything from scratch, which is just lighting money on fire with extra steps.

They did have precedence with the earlier sars virus. And that lab did research on sars virus. And the first outbreak happened in that city. And the group of patient zeroes, a lot of them didn't had any connection to that wet market. There were satellite image analysis of hospitals there have unusual surge activities as early as Aug 2019. And then officially, virus can't be named with that city name, researchers who identified HIV parts on covid suppressed, and only the wet market was the official ground zero for the spread late in year end. That is a lot of coincidence. A court can convict just purely based on circumstantial evidences. So not surprising people came to that conclusion. The main gripe is virus originate from the lab. Whether it is of natural occurance that isn't the main focus.
As a NZer I got thrown when going to California, by asking the front desk staff to do something and then waiting patiently when they said "I can't do that". Turns out when you come from a place where there's a vowel difference between "can" and "can't", that's what you listen for. I didn't at all pick up on the "t" sound at the end.
Heh, yeah. People sort of reflexively back away from the china cabinet. The toxicity of uranium is rather like lead: big heavy atom with lots of bonding available but really slow to move. But no one cowers from leaded crystal (except perhaps the State of California).

Because teachers have rotating lunch duties because it's often against their contract to make them work more than x lunches per week/month, while the child can be arbitrarily put in punishment for more than that.

Just because he was aware of the punishment doesn't make the punishment appropriate. At some point the issue should be escalated or a compromise reached. Allowing to it go on for the majority of the school year is the teacher being unable to control the situation so taking it out on the student to the students detriment instead of benefit.
Dang keeps saying that he doesn't like obvious comments but he keeps posting comments like this: https://i.imgur.com/jdNHIy0.png ... and pagination has been an issue for a long time.... not sure what it brings.

Just search for "(Posts like this will go away once we turn off pagination.)" is you want to find other occurrences.

Just put the pagination link at the top too if you think that it is an issue instead of sticking your post to the top every time pagination is used? Or just fix the website... how expensive can it be to display 1000 comments with no images.
How well did bzip2 run on Win9x Era computers? In my experience, that while the compression ratio was significantly better than gzip, both compression and decompression were significantly more CPU intense.
I suspect this was flagged due to the off topic rule. I loved the article but expected it to get flagged as it's not focused on technology.
Pretty sure school isolation isn't 15 days.

+1, once you get the right indices in place, MySQL 4.x would scale just fine to millions of rows per table. Innodb and Percona were even better. Maatkit was amazing for tuning, as was xdebug.

When you just had expensive queries that were already optimized, you’d use IPVS, haproxy, apache, or RR DNS to help. This was before nginx existed. Static caching pages using Perl scripts to crawl the site and write out everything static as html files worked well too. Varnish was a real game-changer when that came out.

Edit: forgot about Gearman for distributing work as well. Now people probably build the same types of things using SQS and functions.

PHP was never the bottleneck, and the web could definitely “feel” faster back then on hardware an order of magnitude or two slower than we have today with these >10MiB index pages, CDNs and parallel downloads be damned.

Not a half bad stab at a concept I essentially agree with, but it could use some work.

Intermittent starvation was widespread historically. Various religions promote fasting.

We would do well to design more walkable human environments. We used to do that and being active is essential for human health.

But studies suggest a link between diabetes and inflammation, so infection and chemical imbalance in the system seem like better candidates for explanations for it than this text gives.
Most of that boilerplate will be hidden in the libraries which use it. Unless you are a library author I don’t know why you would care about the boilerplate-like elements from the standard— you will only use co_yield and co_await.

> A senior engineer can tell if they did well with an A-B test in the market. A staff engineer can tell if they did well by seeing market share grow.

I don't get this, these are marketing and business skills. I don't understand why tech roles don't leverage the full power of engineering and instead engineers are steered towards tangential specializations. This isn't true across the board of course, but how can companies not see the value of letting some engineers become the technical experts without needing all these related skills? Knowing advanced CS and information theory can help, if anything to keep the other engineers up to date (and I think it would involve technical leadership, just not in terms of managing others), but it's not valued at all and without those other skills it seems engineers just stay as "contributors" (i call this bottom feeders).

It's not a great write up. It did not mention the largest problem of capitalism: the capitalization of ground rent in asset prices. It instead fixates on another explanation: human desire for riches.

> Again, the problem is not riches per se, but the fixation on riches.

The desire for riches is not problematic if the majority of people are willing to cooperate to acquire wealth, and seek income from increasing the mastery of humanity over the environment rather by obtaining at the expense of others. Effective cooperation requires distinguishing between income which is positive sum, which adds to the aggregate stock of wealth, and income which is zero sum, which merely transfers existing wealth from others.

Both types of income are mixed together when capitalized into asset prices. Effective cooperation requires individuals to devise methods for distinguishing between the two and communicate these methods with others.

Capitalism vs socialism debates tend to prevent this from happening because they emphasize either productive income or unproductive income without advancing the practical arts and sciences for distinguishing between the two in manner which allows the majority of individuals willing to engage in cooperative production to do so more efficiently.
Really interesting blog! I queued up 30 posts to read. I’m a climate skeptic skeptic skeptic but I’ll entertain any ideas.
I literally said this at the end of my comment about coroutines being a low-level primitive.
It was much slower that gzip. Decompression isn't so bad, but compression is very slow (epecially with "-9"). The compression ratio was better and every sector I could get back helped. My application was for unattended operation and I rarely needed to recompile the kernel so the time penalty wasn't something I noticed.
Downvote button is not just for disagreeing guys. I’m not even allowed to downvote because I don’t have enough karma but it seems like those who are deemed worthy to are abusing it.
Yes this is one of the main points of the book. What people think is wealth is usually just a lot of debt. Wealthy people use debt to make money. Poor people use debt to buy things, to paraphrase another article that was on HN a few weeks ago.

I frequently evaluate APIs. If you want me to use your API, getting me to a point where I've seen it actually running against some data that I typed in is really important. So give me an API explorer, rate-limited by IP, that lets me click an example link from your documentation and see an actual response.

Ask HN: What's the best way to teach FP to EE/CS students?
I'd like to students to learn the importance of immutability, versioned data structures, pattern matching etc. The hope is that once they get comfortable with an FP language, it will have an effect on the way they write systems in any language. The students are sophomores in EE and CS, familiar with C and python.

I'm looking for an FP language where I can do something familiar (RPi programming, games, web stuff ... but not parsers and type-checkers). I'm looking for the FP equivalent of python in its simplicity of usage and immediate usability.

I have been trying Elixir, but it is more like Elixir is trying me :) I tried the Phoenix hello world application, and it was ready 10 minutes later after downloading 3.1G. I know that it is downloading a lot of batteries, but the sheer amount of things you need to know before you can deploy a silly app is mind-boggling. I tried nerves for the RPi, but it seems like every time you tweak one file, you have to burn the SD card all over again. Again, these are quite likely newbie problems, but when I have to deal with 50 newbies, they scale up! I haven't tried Clojure on the RPi.

Any suggestions? Alternatively, does anyone do FP in python? I am aware of the 'functional' package, and I could always teach functional principles in python (a side-effect free state machine, for example). But having first-class support in the language is so much easier. I have only used FP in the context of building type-checkers, so I don't have first-hand experience.

Sorry for the wall of text, but any ideas will be much appreciated.
I don't care if crypto fails or succeeds.
You are ignoring data sets that go back further from Aircraft and Ships and ocean buoys and there are more types of readings available and you are assuming that I intended you to stop at 4 or 5 decades ago and go no further! It's your lack of usage of that ACE metric and other datasets that are allowing for even finer grained tropical cyclone intensity measuring analysis.

Your extremely limited sampling of the historical data sets will not pass muster in any peer reviewed scientific publication or Academic setting and I'm not leaning either direction on the matter but to say that your sampling method is much too cursory to pass any stringent review process.
I'm very curious how the author imagines the beginning of that process works. Where does your first security deposit come from? How do you pass any sort of credit check? Your first paycheck won't come for a couple weeks, so how do you buy groceries?
I tried to find info about this compound but only got links to various articles reporting this story...
More control, maybe less cost? If your cloudy provider has an awful solution like the one I was using, you'd get better uptime by doing it yourself.

I haven't heard many problems with AWS or Google load balancing, but sometimes there's issues where people talk about 'pre-warming'... more control would probably help there.

If you're running HAProxy on AWS, be sure your AWS firewall rules are stateless, otherwise you may well run into the unpublished connection tracking limits.

Only on a 100Mb network and use OpenBSD with an APU4 so it’s more than fast enough for my connection, speed isn’t a problem.

The big advantage I see with OpenBSD is the simplicity.

Everything about it is simple. Where things are installed and how they are configured is far more consistent than Linux. The inbuilt man pages are fantastic compared to other systems. The fact it comes with nothing installed and you need to turn things on makes it easy to manage as you know exactly what is running, in turn this makes keeping up to date easier. Pf is fantastic and again simple.

From not knowing OpenBSD only using Linux before I had a home network with multiple VLANS, cross vlan routing, nat, dns filtering, dns over tls etc in very little time.

I’ll be honest the reason I switched to OpenBSD was mainly to play with something new. I previously had a home router running dd-wrt which was ok but clunky ui, hard to know what was running, upgrading was downloading random untrusted binaries off the internet for specific builds that work on my router. I decided this isn’t great so my options where play and build a OpenBSD router or try something like the EdgeRouter.

I am glad i went with OpenBSD, it doesn’t hide anything from you, you have absolute control and it’s simple to configure with a few static config files. You really understand what is happening.

On top of that, since setting it up, I’ve never touched it. No reboots, no going changing settings, it just works. It’s been set and forget.
To provide an opposing viewpoint here: ES and it’s monstrous API and resourcing requirements are a pain to manage and run. It’s a product that has pivoted in so many directions that it’s just become a bit of a mess. I don’t want a full-text search engine that also has graphs, ML, some bizarre scripting feature, log management, etc all stapled in on top. Geospatial and other analytic stuff I’d rather use a dedicated OLAP db like Redshift or ClickHouse.

I’m currently evaluating typesense vs ES for a fts project and typesense is winning so far by simply be “not painful” to deal with.
