In their defense, some of the questions and that they're asking are about how our stockpile degrades over time - which hopefully means keeping weapons on ice longer instead of having to reprocess and build as many new ones.

There was a really popular trend among cryptocurrencies at some point of creating a new proof of work function as a way to differentiate your coin from the sea of Bitcoin clones. Coin creators would then make unsupported claims about why th

Howdy, neighbor! Thanks for this - I'm glad to hear he's still doing cool stuff. I'm off to watch that now, in fact... :-)

Related, there are a few cryptocurrencies that used things related to finding large primes as part of their proof of work functions. It turns out that ~8 years ago, a really fast primality test implementation could make you a lot of money.

Where'd you get the drives? That's a quite reasonable price.

by dgacmu 2y ago
This probably isn't normal consumer price, but supermicro makes some very nice nas-targeted hardware that you can populate with your own drives and choice of OS. I have one with 183 TB running trueNAS (zfs) and it's great. They&#x

A transfer-switch based UPS still needs to protect against brownouts, so it too has line behavior parameters outside of which it will switch to battery. It's an interesting question if/why a modified sine wave input would trigger

by dgacmu 3y ago
I've tested it before. TFA is correct, at least with the APC UPS I tried it with once. The apc ups went to battery and then turned off when out of battery.

by dgacmu 3y ago
Not really. In your case, you probably have a very high quality pure sine wave inverter that's much larger than the individual UPSes, which will make the downstream UPSes mostly happy as long as you don't approach max load. Many c

Oh my gosh that is totally charming! The clock i repurposed for ours has a bit too much of a "this belongs in an office" vibe. Fun to see how different the same idea ends up. I had the same concern about kid-proofing, but I took t

Someone else on HN mentioned a couple of months ago that they were using a power meter for the same purpose. There are a lot of cheap zigbee and zwave outlets that will report power, though you'd have to implement the thresholding logi

I tend to roll my own with rp-picos for no good reason other than they're easy. 1) Wattmeter for a toy solar installation - broadcasts a UDP packet every few seconds, which I then record into a staging JSON log that gets ingested into

I think it's useful to draw a distinction between instructions that are somewhat complex versus overall design choices that make decoding (and scheduling) hard. Like, does it really matter if you have a reciprocal square root instructi

You can use a 100g DAC within a single rack (which is also cheaper). I only have a tiny bit of 100g at home and just do 10g optics for the connection out of the rack. Of course, that's my weird setup and it won't work once I want

Also prof: me too. I'm much more likely to provide comments on the first couple of exams I grade than on the later ones. I've found that gradescope is helpful in this regard, because it at least forces every point assignment to be

I'll bite: because after all is said and done, I believe we're more likely to have something of value left over from the AI craze than from the blockchain craze. The energy that goes into training a model gives you something that

Now hold on, you could carry around a miniature white projection screen with you. Maybe about the size of a plating card but thicker, maybe a little bigger, but sized so you could comfortably hold it in one hand but still fit it in a pocket

This is the core thing. Our acceptance rate is extremely low - under 10% for computer science. There are a lot of things we want to accomplish in admissions; _one_ of them is a statistical bias towards being able to succeed in the program.

We are a little closer to Harvard in that regard: we are private, but one thing we do is that our admissions are direct into the department, though handled centrally. But regardless of the incentive, it does nobody any favors to put them in

I can't speak for Harvard, but I can address my own university: The pressure to resume using test scores came from the faculty, because we observed that there were an unusually high number of students admitted who were failing the math

No, there literally is always a tradeoff, even in human medicine. I was at my doctor's office yesterday because I'm an idiot and injured myself. I asked about the diagnostic advantages of getting an MRI vs an x-ray for the injury

No, because they have a different internal crystal structure with more space. The kosher salt is, to use a vague term, more fluffy. There's a photograph in this Cooks illustrated article, if you go to the end of it and click read more:

There are two general attack targets I'd use if I had access to a library/binary like xz: (1) A backdoor like this one, which isn't really about its core functions, but about the fact that it's a library linked into crit

To put this in different words, you're basically asking about steganography applied to a radio transmission. I think the answer is: unlikely to be noticed unless you were receiving particular attention for some reason. Though your nois
