No, this is not true at all. "The extra cycles" is the exact thing you want to avoid in HFT. It doesn't matter how much throughput of processing you can put through a single core if you enable SMT, because somewhere in the path (either broker, exchange, or some switch in between) you will eventually be limited in throughput that it becomes irrelevant.

The only thing that matters at that point is latency, and unless you are cache-friendly enough to store your entire program in a single core's cache twice over, you would be better off disabling SMT altogether. And even if you were able to do that, it would not matter as a single thread would be done processing a message by the time the next one comes in. At least at the currently standard 10-25Gbps that the exchanges can handle.

In HFT, we're fine giving up half the registers in a core if it means we get an extra few microseconds of latency back.

One more technique to find the backend IP address of the web-server is to lookup the DNS record history of the domain in question. Usually, the admins will test their website with with SSL on a real domain to ensure it works.

Only afterward, they will protect it with Cloudflare/Akamai/Cloudfront, etc, which means you'll have a DNS history trail to lookup.

I've had good luck with services such as SecurityTrails, Virustotal and CompleteDNS for DNS history.

Once you find the original A record IP address, you can put it in your hosts file, pointing to the domain. Then, you will be able to access the site, bypassing the CDN without issue.

These days the distros themselves all support it fine and the built in programs all work correct. But any program which relies on the XWayland compatibility layer does not work as X11 has no support for live switching dpi without killing the window and recreating it.

You realize supply growth was significantly larger with PoW, right? It's like saying "Ethereum uses energy too!" completely ignoring the fact that it uses 99.9% less energy.
TRAP is the right way to do it though. They're syscalls. That's the m68k way of doing syscalls and to elevate to supervisor mode etc.

From today's POV some of the stuff in the VDI and AES maybe doesn't belong in "kernel" and would be done user space. But it was the 80s, and it all had to fit in 192kb, there were no shared libraries. It was a different time.

That AmigaOS didn't use TRAP is a bit odd.

It's funny to me that this is such an offensive idea that it needs to be downvoted. It seems pretty straighforward and self evidently true.

Well yes, but "embedded" is a pretty broad category.

Some major cases are:

- High-volume and cost-driven: where a you're picking the cheapest MCU you can make work (often by a matter of cents).You want to squeeze every last bit of performance (or IO, or power consumption, or pinout, or whatever the drivers are).

- Real-time: where abstracting the hardware beyond a certain point is counter-productive.

In my experience it's much less common that you don't care about the hardware than the reverse.
I was just thinking about this. This ought to be trivial on cartoons, I'm almost surprised it doesn't exist yet. People legitimately would like to change the race of the princess in the princess movie they're about to put on for their daughters; it's nice to be represented on the screen
Sorry, I should have been clearer. "The work" here referred to assisting with the reverse engineering aspect of this.

In 1990, RS-232 used 25-pin ports (DB25), and the DB9 ports were "new". Why they used 25-pin ports for RS-232 I'm not sure, since only a fraction of the lines (less than 9) were actually used, probably some silly historical reason. 25-to-9-pin adapters were very common then.

The DB25 connector was also used for parallel ports as you said, which caused confusion sometimes. But on a standard PC, the printer port (parallel) was a 25-pin female port, whereas the serial ports (25 or 9 pin) were male.
I'm just fed up with modern sound. It never sounds right, and it's just too complicated. I use captions on a lot of shows where there is dialog that is too quiet, etc. I'm pretty sure my sound system is not set up right, but I just don't want to figure it out. I debug software for a living. I just want my entertainment system to be plug and play.
Literature is often polarizing. You see many literary novels that get a U-shaped rating distribution, with most readers either loving or hating a book. I think the best explanation for this is the distinction between plot-oriented and character-oriented readers/writers. Plot-oriented readers want a logical development of events and will tolerate shallow and interchangeable characters (as in most hard sci-fi). Character-oriented readers want development of personalities and relationships, and have less demand for structure (as in much fantasy). Perhaps the controversy over The Rings of Power is an example of this.
> The current CEO of Adobe has been CEO since 2007 and has led their awful Creative Cloud strategy.

I know it's fun to rip on Adobe, but it's worth putting this in context.

In '07, Adobe's stock price was around ~$40. Today, even after the (undeserved, in my opinion) thrashing the stock has taken for the Figma acquisition, it's at $300. He 10x'd a multi-billion dollar company in about a decade and a half, while also simultaneously redoing its entire monetization strategy. It's nothing to sneeze at.

A quick search turns up interesting numbers from this press release a year ago (literally the first result in my search, so not digging too deep here) [1]:

- all-time record revenues in Q3 2021
- 20-30% YoY growth in every segment they play in
- the DocuSign acquisition has turned into a cool ~2B/yr business
- and creative revenues of 2.4B, i.e., almost 10B/yr

As a handy rule of thumb, I like to assume that any long-term CEO of a profitable multi-billion dollar enterprise probably isn't a moron.

Is Adobe a dinosaur? Absolutely. Stock buybacks are a great indicator of this, in my opinion.

Could Adobe screw this up? Absolutely possible. As a good example, they do plenty of dark-pattern UX in their subscription and cancellation flows that I really don't like.

With all that said, I think there's a decent chance that we in the peanut gallery might look back on this in a few years and see it as a brilliant acquisition in the vein of WhatsApp and Instagram. Figma is a world-class product, leaps and bounds ahead of anything else. Considering the price they paid, I bet Adobe understands this is an existential issue for them.

I stopped reading as soon as they quoted that silly inaccurate UoC website that gets quoted over and over again.

Why? Because they even admit, in their own methodology (https://ccaf.io/cbeci/mining_map/methodology), that it is an extrapolation from less than 50% of the total hash. Even worse, is the pools they extrapolate from have been Chinese based. Although, that's changed over time, which invalidates their numbers even more.

Even still, there is no way to know how that power is generated, how much it offsets other power generation, etc... there are just too many variables to simply quote UoC.

It is indeed interesting. Some sites even let you view their content without JS, registering/subscribing, and/or revert back to something approaching an unstyled static site without showing any ads, sidebars, or other useless content.

Ask HN: Will AI-based codec be the future of video compression?
Watched Two-Minute Paper’s latest video and saw that NVIDIA’s research team was able to push out compression rates much better than h.264.

Honestly, I don't think they really gained that much political capital. Not since the civil rights era. What's happened as of recently? People tweeted #blacklivesmatter, talked about how awful it is that black people deal with police brutality, and then a few places voted to defund their police departments. None of that seems to be anything that actually helps that black community, or improves their situation in any way.

BLM just became the political issue du jour for a month, some people protested while some journalists talked about it, and then interest fizzled out. In fact, police brutality is still just as much an issue today. It seems trans rights is more talked about nowadays, though. Looking at their racial breakdown and it's not surprising that they have more political capital.

This can be a useful approach when you have a very large number of states (as long as you also don't revisit states). In this case, there are few enough states to just BFS the fastest way directly.

I don't know whether you would call the author a supporter yet, but from the article, with respect to an issue that matters for gamers:

"And now you have done something X11 cannot do - eliminated screen tearing with the absolute minimum latency cost possible.

"This [is] fantastic.... And like, this is the first time I’ve ever seen the vsync setting in a game actually sync the game up with the vblank interval in a way that matters. It works for games in wine. It’s amazing. I have never experienced gaming on Linux that looked this smooth in my life."

Motorola m68k @ 8mhz = ~1.4 MIPS

So actually 13000 times more powerful just in that one metric (instructions per second). Though of course it's more than that, as throughput in memory access, and concurrent operations and 64-bit math etc obviously much faster.

It is significantly easier to make friends being an incoming freshmen in the dorms, as everyone else in your cohort also has no friends and is always around. If you're outgoing, this isn't much of a problem, but as a sophomore transfer student who never lived on campus, I struggled with this pretty heavily. It's probably not worth >$10k between tuition / room and board to be able to make friends easily, but there is a downside.

"In this system, if supply outweighs demand, price will go up."

I'm pretty sure he's got that backwards.
Yeah that's the workaround that some people use.

But you see the catch right? People buy hardware to have support from the manufacturer. The no QA part is very very bad. :/

Nobody wants to be the one troubleshooting issues all the time, and that can alone make an NVIDIA GPU worthwhile to buy over an AMD one.

Hopefully this gets fixed in the future.

and maybe some very big past mistakes too. See the G4ad instance on AWS. That runs on the Navi12 ASIC, which never got (proper) ROCm support. Wouldn't it be awesome if an AWS instance was available widely for people to test their software with ROCm? The hardware is already there...
TBH This response is way too aggressive for the original comment.

The facts stated are simply that today it is more efficient to encode video for remote graphical sessions because the X11 applications already changed a long long time ago to adapt to the modern world of GPUs and accelerated compositing. BW, latency, efficiency, everything became better because a super computer with thousands of cores can do that and lighten the load on the CPUs.

It doesn't say it doesn't work...
It doesn't prevent you neither from running X11 or even booting up a PDP-11 if this is your favorite workflow!
The federal government doesn't generally pay for education. That's state and local dollars, mostly.

The states do pay for education, but during and after the 08 recession (and generally during the 70s-90s too), they have cut funding for higher ed, to put more into k-12 and tax cuts:

https://fivethirtyeight.com/features/fancy-dorms-arent-the-m...

Cuts in state support are balanced by tuition increases; expenses on a per-student basis are not up anywhere near what tuition has increased by.
