Most logging is insanity in action. Behold:

1.2.3.4 - - [08/Aug/2023:12:48:11 +0200] "GET /wp-config.php.bak HTTP/1.1" 404 196 "-" "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2503.0 Safari/537.36"

1. Apache has a perfectly coherent and structured view of the situation: Host 1.2.3.4 made a GET request of this particular URL, with this particular UA, at this particular date.

2. Apache proceeds to shove all this into a string, destroying the structure, and probably some of the data (it likely knows the timestamp with >1s precision)

3. Then to do some sort of analysis we need to manually reverse this process: write some convoluted regex to match this kind of line, turn an IP address back into a number, turn a timestamp into a number, find the delimiters. We're now undoing the damage Apache did. Why!?

4. For extra fun this adds extra problems to deal with log rotation, log compression, newlines and special characters in fields, and so on. All kinds of problems that are ultimately unproductive to solve and get in the way of actual useful work.

Logging should be structured by nature. I shouldn't be writing weird regexps. I should have every message structured from the start, where I can search by "ip_address is in 1.2.3/24", or "request == 'GET'", or such. Every bit of data should be logged in its pristine form with zero ambiguity, with its original type, and analyzable accordingly.

I think systemd has the beginning of a good idea in here, in that you can actually do this if you care to, and can send arbitrary chunks of data (even binary) to the log if needed.

People who complain about journald not logging in plaintext honestly baffle me, because come on, whose idea of fun is it to do log parsing? And why are we spending CPU cycles on converting timestamps to text and parsing them back?
> Sure, but there's no generic "db rollback" command that reverses the last thing you did.

Technically nothing prevents the database automatically creating a subtransaction / savepoint for every operation you perform.

> This command would have to decide what to do for every previous command, no?

Yes? Not sure I see what the issue with that is.

And technically much of the information is already encoded in the reflog. The two big additional informations you’d need are:

1. Tracking changes to refs as they’re not necessarily tracked by the reflog, but there should only be a small number of plumbing operations manipulating refs so it’s not really a concern.

2. Tracking changes to the index, would likely be a lot more difficult.
Just because a Twitter said it's over doesn't mean it's over. Prediction markets still think there's a ~1/5 chance of it being legit.
We've had that in forums and IM, but it never took off. Maybe it was just too early back then, but I'm not sure.
I agree with your first statement, but your second statement means that you think FB should be compelled to serve free riders. If you are being compelled to serve users that are unprofitable, a clear implication of the GDPR, then you are compelling free ridership. The difference between targeting and not is the different between net profit or not for many users.
What I really want to know is, can I as someone compelled to use Zoom as an employee can opt-out of Zoom training their AI on my voice, image and data?

If my employer is the "customer" what say, if any, do I have as an individual?

By participating in a call am I giving Zoom permission to do things like train deep fakes of me?

This is all too Blackmirrory for my liking.
Can you point to read-only snapshots that way?
As expected, this is not due to trade with Mexico increasing, but due to trade with others decreasing.

Is it because the US economy is becoming stale or because it is diversifying its trade partners?

Also, this is just another sign that the world is indeed shifting to a multipolar order.
The system exists. It's text.
I have not had the same luck with the video calls as you. People have mentioned “new Teams” which is perhaps better and more stable. When I used Teams last year it was not at all comparable to Zoom
Yeah but "scanning people's eyeballs to build a database" is untrue. You can scare a lot of people by telling them untrue stuff.
In previous threads I read that this material is very tricky to make, that nobody has succeeded in making a pure sample, and therefore we should expect many negative results and that they don't necessarily mean anything conclusive.
Maybe but I doubt it's an intentional hoax. It's much more likely to be a mistake.

It took them time. I had asked the same problem few months ago [0]. I needed a tool to subset a huge PostgreSQL db. The choices where Condenser [1] and this Jailer. Since I'm not a Java guy, I was struggling to know how to properly run this Jailer. I'm glad they released a .deb format. But I ended up using Condenser.

I don’t think it’s about being unsatisfied or unhappy with your current achievements, more just cultivating a mentality that there’s always something new to build and look forward to.

The way this phrase is worded is weird in my opinion. It sounds more like a political statement rather than a scientific one.

To use a word like hoax would require at least some hint of the authors falsifying data or intentionally misrepresenting things. LK-99 is still very magnetically interesting even if it is not a superconductor. Interpreting those interesting behaviors is where things seem to have gone wrong.
Some design decisions are also really not obvious. I've seen engineering decisions of the kind... We'll put another microcontroller because we would need less wiring between these 2 boards and the wiring would be more expensive.

A clever one I saw was where they milled a PCB thinner in a section to make it bendy and did not need 2 boards because of this.
> But after looking at other source control options

Genuinely curious: what other VCS are you referencing here?

Personally, I have not used many, but of the total of three that I have used, Git is the hardest.

I've used SVN and I will start by saying that Git is objectively better. But that "better" is a balance between ease-of-use and features/power. SVN is much much nicer to use than Git in certain (admittedly narrow) contexts. To be more specific, the SVN (cli) user interface is a lot nicer to use than Git's. Merge conflict resolution is improved in Git, and decentralisation is pretty useful - the ability to setup a local repo and persist changes to disk immediately with no remote is essential in modern version control. These things make Git better but it is not easier to use.

Then of course there's Mercurial: somehow delivers on all the things Git has over SVN while still being almost as easy to use as SVN. No competition here.

I’m not quite sure what you have in mind but it’s not really abusable, it just won’t deteriorate as quickly as other types of painting.

If you cut into it then you may or may not get different colors depending on where you slice. In that sense it’s not much different mechanically than oils, just with way more depth.

Thanks for asking!
Social media attention perhaps? Mainstream media doesn't seem to have been paying much attention, and generally rather cautious over the whole thing.
No it wasn't. Things like this (or at least the dubious media frenzy around this) erode public's trust in science.
> The first problem with monitoring this way is that there's no guarantee that the message you're monitoring for won't change.

This is a solved problem (at least for the linux kernel) with printk indexing[0]. So you can query the running kernel what log messages it can output. With that your monitoring tool can check when an expected message was changed and you get the messages in printf format so you can parse them if you want.

> Yet they cannot refuse to do business with us...

I obviously know little about business and "trade", because this strikes me as odd. I mean, I get that it's contractual, but how could a well-written contract not anticipate a time when doing said business with you would be detrimental to the company forced to pay...

And, long term, such a situation hurts both parties, because if "this obligation becomes part of what kills them", the business on the receiving end also loses a customer.
> to those hundreds of millions Chinese pensioners on $25 USD per month

There are almost 40m americans living under poverty, which is just about the same as china in term of percentage. The 25 usd a month figure seems to be for a social benefit system you don't even have equivalent for in the US

What's different here is that this sample is exhibiting some of the properties that a successful sample would, indicating that this is not an outright dud. They also seem to have an explanation for why/how they might observe those properties but not superconductivity.

This is in contrast to someone claiming their sample did not exhibit any of the properties of LK-99 at all.
That isn't the point I gleaned from reading it. The gp seemed to be making a specific point about Git, not about text based tools in general.
As ex facebook - no, that’s not how it works. they’d be lucky to even have multiple heads in Norway and all the shots are taken in MPK anyway. These fines are act of god in their eyes, a tiny spec in a sea of money.

Unless you throw an executive to prison like Brazil or force temporary shutdown like India or leverage three digit million fines like the EU … it’s all pocket money.
Eindhoven (NL) would have been obvious as well (NXP, ASML, Infineon, Philips)
Definitely not. This definitely sounds like recency bias. I'll bet 9/10 of your non hacker / engineering family/friends don't even know what LK-99 is. I know thats the case for me at least.

Honeywell was recently fined for FCPA violations.

I don't see it as overreach that the US does not let foreign companies that pay bribes compete in the US. Given that US companies cannot pay bribes legally, it would be hard for them to compete domestically with companies that can bribe simply because they are headquartered elsewhere.

> Curious why they've chosen Dresden though.

The region is known for its semiconductor industry, at least in Germany. Quote from Wikipedia about Dresden:

> Silicon Saxony Saxony's semiconductor industry was built up in 1969. Major enterprises today include AMD's semiconductor fabrication spin-off GlobalFoundries, Infineon Technologies, ZMDI and Toppan Photomasks. Their factories attract many suppliers of material and cleanroom technology enterprises to Dresden.

So it just makes sense to build fabs in Dresden because there is already a lot of know-how there.

Science is like that. The problem is not with science or with this material not being super-conducting. The problem is with how science is explained in media. Failing to test hypothesis is a critical step in the scientific method.
I've noticed this trend among my fellow 80s kids - connecting out was either expensive or impossible for many so they dove deeper into the details of how their computer worked.

I have found that being able to stay on task and dig into these things has become a lot more difficult as I get older - part of that is probably age but part of it is that I have a World of Distraction available just a click away, and the pull of cheap dopamine is strong.
A much better strategy is to work slow :). Drag out every phase.
Sort of incredible that Germany is getting decade old technology for this much investment.
Unless they decide they do. That's the strange thing about sovereignty in a democracy.

It is worth remembering that there's no such thing as a "global" company, by the way. These are largely American companies. They are structured to be unaccountable to other countries, and this is one of the ways in which american imperialism works.
I wonder if there's been a scientific study that tries to correlate the tone of a statement, with its reliability.

My gut feel is that such emotionally charged statements are likely inversely correlated with accuracy.

I'm surprised this is the twitter account of a reputable organization.
Honestly I'm happy enough that emoji are there as a carrot to upgrade their platform support for newer unicode revisions which the US otherwise might not care about.

This study https://arxiv.org/abs/2308.03110
What data is there that it is?

Why is not the initial claim a strong statement? And if the strong evidence supplied is the method to reproduce and no one can reproduce, then that should be evidence that their evidence is lacking and therefore their original claim is suspect.

Until someone can reliably reproduce the claims of LK99, it remains speculation.
> I feel like such strong statements should directly reference strong evidence

That's not the way the burden of proof goes! Consider "Fluoride Toothpaste is not a Superconductor".

What you want is conspiracy logic: assume something interesting is probably true based on weak evidence (a handful of videos on twitter seems like table stakes in this particular controversy), and then when people deny it you demand that it "should directly reference strong evidence".
Dresden has been a semimanufactoring hub in Eastern Germany for quite some time.

I believe this started in GDR times and continued (at massively reduced capacity) after the reunification.

Intel, AMD, Infineon and others operate (or plan to build) factories in Dresend (or saxony in general) and its reasonable to assume that experienced workers and local suppliers make the area a preffered location.

Given Eastern Germanys weak economic situtation these are very welcome investments.

Keller was great. He was actually great in all public appearances I saw him in. And I find it hard to find something I disagree with him. Usually with people I look up to, there are _some_ things I'm not on board with, but I don't seem to have that with Keller.

I understand that until recently he kind of stayed out of the public spotlight, and I wonder why, because he has such a great presence.
What benefit does that bring?
Monitoring logs is the last line of defence. If you're advocating against monitoring logs, then well, that's your opinion and certainly not mine.

A LED bulb = LED(s) + electronics.

It's usually the electronics that dies (specifically: electrolytic capacitors, if included).

Life of the LEDs themselves depends a lot on operating temperature. Running hot (like in the cramped innards of a bulb), their output gradually decreases or they burn out @ some point. This is the fate of many cheap bulbs with poor thermal design.

Separate electronics (read: and their waste heat) from the LEDs, cool them well (and/or run at reduced power), and the LEDs can last practically infinite. Just like standby LEDs on appliances don't burn out. And -potentially- failed LEDs or driver electronics can be replaced independently.

But this does require a purpose designed fixture. Chip-on-Board (CoB) LED is the keyword here.

That was my immediate thought too. That was an interesting time to be alive.
This problem seems completely unrealistic because then you simply buy through the countries they haven't banned? What you're suggesting will only work if said country is a global superpower that can bully every country to tow the line. At the end of the day, no country can produce all the "critical" things it needs so this national security defence of restrictions on trade seems like a very unwise insurance to buy in almost all cases except maybe your millitary supply chain.
This isn't the first unprofessional message from that Twitter account during the lk99 saga. Their biased tone makes them untrustworthy. Even more than anime girl et al
That's some control. One example - last year one brave lady from TV staff protesting IIRC via banners against the war in state TV. I hope she is still alive and well (for that part probably outside of russia).

Of course the ultimate goal would be total control, so they counter similar situation (or putaine giving some speech live in tv) with ie 1 minute delay to counter any 'mishaps'. So they are going there, but slowly, ineffectively, at least for now.

Russian state can't unroll all freedoms immediately, their main goal was to paint war as "nothing is happening, just minor security cleanup". Putaine's clique is, just like any dictator, scared shitless of people revolting en masse, there is nothing more important for them than keeping the power and stealing all those juicy billions in resources and services flowing. But for majority of russians to revolt, they would have to go quite a bit beyond FUBAR, population is trained with patriotic spin to suffer incompetence of its leaders for generations.

I don't think most people really care that much about performance; rather a vocal minority. Most devs are not that discerning in choosing their tools: they'll happily use what's given to them or what's mainstream when they're learning and stick with it as long as they can. This is the quiet (massive) majority that mostly don't post on HN.

I see a lot of people attributing Git's "win" to GitHub, and that's likely the biggest nail in the coffin, but the GH devs chose it because it was already reasonably popular and it was popular because of Linus Torvalds.
I ran a few tests in Windows Terminal. The bomb emoji got width 2, while the motorboat got width 1 and correct aspect ratio, though I didn't quite get to see it properly until I zoomed in like 5x. The family was rendered all as one emoji, cells wide, but left 4 blank cells before it.

So it was a bit better than the authors tests, but there's still room for improvement.
