I'd like something like this but for houseflies instead of mosquitoes. Although, I suppose a simpler solution would be to install a cat door rather than propping the back door open.

My idea for a health tech start up: make a (relatively) cheap MRI machine using high-temperature superconductor tape

Quad9 is based in Switzerland, so the German court should only have jurisdiction over whatever servers are in Germany. It seems like the worst case scenario is that Quad9 shuts down their German servers, but still serves German requests from servers in neighboring countries.

That said this is still terrible and I hope the German court reconsiders their decision. The free flow of information is more valuable than protecting copyrights, because the former benefits many more people. Most of the copyright holders who feel threatened by piracy are not even German! The court is protecting big American businesses over individual Germans.

>I remember getting a call from the fire department commander telling me that they were not sure they are going to be able to contain the fire. "I said, "you know, we've had such terrible loss of life, maybe the smartest thing to do is pull it". And they made that decision to pull. And then we watched the building collapse.

It sounds to me like Silverstein and the NYFD were talking about pulling firefighters out of WTC7. Once the fire department realized saving the building was a lost cause, there was no reason for firefighters to remain inside and risk their lives further. I don't hear anything in the video about "pulling" the building down.

What is the practical application of this? Free energy?

I use GNU Parallel for long-running jobs for its --eta option. If a job will take days or longer it's useful to know that early in the process. You might want to cancel it and try something else, and if you want to proceed with the long job you can make plans around when your data will be ready.

This is a well-written and insightful article, but I don't think it's good for HN. Divisive political and culture war issues are thoroughly covered elsewhere. I would prefer HN to focus on its unique niche and show me new ideas I have not encountered before.

I recommend CARTA, the Center for Academic Research & Training in Anthropogeny. They have many academic lectures on human evolution on their website. In particular, check the "Past Symposia" section.

CGNAT is standard on mobile connections, it's more common than getting your own IPv4 address. Over the last few years, it's becoming increasingly common for residential connections, because ISPs can no longer get additional IPs for free from their regional numbering registry.

It's now cheaper for ISPs to deploy CGNAT than to purchase new IP blocks. Since IPv4 is provided for legacy compatibility, performance is not a priority.

IPv6 is faster and more reliable because the user can connect to your site natively instead of going through NAT and CGNAT.

This is like Edward Tufte meets Donald Knuth

>why would they be trying to actively get rid of people?

It's extremely demoralizing to work with people who are bad at their job. It makes me feel as though my hard work is unappreciated, because someone who is not working hard gets the same treatment.

Sometimes the employee is slacking off, sometimes they are bad at their job. Either way, if their failure to contribute is bringing the rest of the team down, they have to go. Otherwise, the good people leave to get away from the bad people.

I cook in titanium pots. They are marketed to ultralight hikers, and are mostly too small, but you can find ones large enough for kitchen cooking. It's easier to clean than iron or steel, but not as easy as teflon. The nice thing is, unlike coated pans, you can use copper wool on titanium.

I don't think gender ideology is an appropriate topic for HN. There is little to be gained and much to be lost from discussing it here. Little to be gained because it has nothing to do with software development, and because gender issues are thoroughly covered elsewhere. Much to be lost because gender issues are so divisive that we risk alienating members of our community.

Are the numbers the size in bits? If so, those are very small blocks. It seems like you would get more effective redundancy with larger blocks. Does Reed-Solomon scale so poorly that only tiny blocks are computationally feasible?

I second this. For those who don't know, tkrzw is the less-memorably-named successor of Tokyo Cabinet and Kyoto Cabinet.

Noise shows up as light gray lines or dots in the DFT. In the Imagemagick example, this noise is removed by replacing those parts with black. But you want to do the reverse, so you should add noise by adding light gray features to the DFT.

I suspect this technique is how the Imagemagick author generated the noisy twigs image: https://legacy.imagemagick.org/Usage/fourier/twigs.jpg

If you want to go even further, Imagemagick can operate on the discrete Fourier transform of an image. The effects are unintuitive but powerful. Read the documentation at:

You want to legally mandate backwards compatibility? That would cause all kinds of unintended consequences.

The ability to break backwards compatibility has been central to the continued development of every platform. Windows, Mac OS, Android, iOS, the web, are all unable to run certain old programs. Some of these platforms offer more compatibility than others, but none offer 100%.

Most of the time, the breaking changes end up being good for consumers, especially in the long run. Change is necessary for technological progress and banning such activity would be like throwing out the baby with the bath water.

Do you plan to remove invasive weeds and plant native wildflowers/trees?

I don't see an ATX header on the motherboard. I wonder if this will be compatible with a standard PC power supply.

If this happened to me, my gut reaction would be to connect the hard drive to another, working computer, and do the recovery in a fully functional environment. With all the physical work required, it probably would have taken longer. But if anything else unexpected happened, it would have been easier to deal with.

For me, it was Avara. An online multiplayer FPS in 1996, when 3D graphics and the internet still felt like science fiction. The skill ceiling was high and games were very competitive. Shout out to the ®ed §quadron, the clan I was in. I am still in touch with friends I met in the game, more than 20 years later.

The game has been ported to modern OSs: https://github.com/avaraline/Avara/

There is a video of gameplay with commentary here: https://www.youtube.com/watch?v=AutG8KO4DsY

>only fixed-size types

I agree that intmax is silly, but I believe there are legitimate uses for variable-size types, like int_fast8_t and uint_fast16_t. These are their nominal size on x86 because the architecture has arithmetic operations for those sizes. But on POWER, they are both 32-bit types, because there are no 8-bit or 16-bit opcodes, and emulating overflow behavior with bitmasks incurs a performance hit.

You fumbled the math.

>doubling wind speeds gives ~8 times the power

This describes a cubic relationship; 2 cubed is 8.

>doubling the length of the blades gives something like 4 times the power output

This describes a quadratic relationship; 2 squared is 4.

0.9^3 * 0.9^2 = 59% of the energy, much better than the 20% you claim.

This reminds me of Dave Taylor's idea for "pinky processors". These were similarly minimal, relying on conditional branches to do much of the work. Taylor thought massive numbers of these clocked at high frequencies would deliver more computation than complex high-IPC processors. He was wrong, as the failures of the Pentium 4 and AMD's Bulldozer would later demonstrate, but at least he was ahead of his time.

Unlike Taylor's ideas, this MyNOR actually exists in the real world, which is all the more impressive considering how impractical it is.

I don't believe there are any POWER machines using UEFI. The standard POWER boot process uses OPAL (Open Power Abstraction Layer) instead. But POWER does use GPT disk partitioning, which is from the UEFI standard.

I use Mate and I think it's misleading to characterize it as a reheated Gnome 2. That's how it started, but the project has come a long way since then. Mate now uses GTK3 instead of GTK2. It supports GPU-accelerated compositing and Hi-DPI displays. Mate is a well-maintained modern desktop environment, not a historical curiosity.

Presumably involving MDMA in an MC-303

SubEthaEdit is a nice enough text editor that it deserves consideration even if you never use its networking features.
