The niche killer feature is the 800GB/s SSD ...so long as you only need 8TB.

You can't match that speed with nvme. Samsung 990 Pro only gets 7.3 GB/s sequential read.

edit: I stand corrected.

LLM inference is GPU bound and VRAM bound. Given quantization however, 2x3090 or 4090 (48GB) is enough VRAM to load 65B quantized llama derivatives (30-40GB). With exllama you can get maybe 20-30 tok/s with dual 4090s on ~1200W. With an M2 Ultra maybe 10 tok/s on ~178W.

(I don't have these devices but have been researching LLM inference performance in the interest of buying a machine for them.)

Advantage goes to M2 Ultra if you ever might need more than 48GB VRAM. I think it's unlikely nvidia is going to release a significantly higher VRAM consumer card anytime soon, since that's what their A100s are for.

I'm guessing most people either don't bother with it (I haven't...) or write their own ad-hoc file integrity managers using checksum files and par2. I was about to try something, but decided to go look for existing work instead.

There's a proliferation of backup software, but this is the only file integrity solution I've come across. Surprising, since file integrity is the only way to know if what's being backed up is any good.[0]

SEEKING WORK – US/Atlanta – Remote Preferred

I'm a senior CS student at Georgia Tech starting out with freelancing. Preferred technologies are go, java, dart, flutter, and linux shell scripting, but I pick up languages and platforms pretty quickly and have also done some programming in c/javascript/julia/perl6/python.

I'm willing to do pro-bono work for the right client if I can use it as a portfolio piece.

One thing that makes Anker stand out to me is that they pay attention to the unboxing experience, which I haven't seen from any other company in a non-premium market like cables and car docks.

This is pretty good as far as grand theories of the universe go, which in fine because we're talking philosophy, not science. However, I don't agree with life being an oppositional force to normal increasing entropy. It's probably more like eddies in a current, where life can only exist where free energy / negative entropy / information already exists and can be used.

You might be interested in a book I just added to my reading list: "What is life?" (Schrödinger, 1944) The wikipedia articles on it sound fascinating.

The previews are nice, but they do tend to catch the eye and make it difficult to quickly filter out unwanted results. It's hard to skim the result titles. I do like the tiles, however.

The clickable suggestions at the top are an awesome idea. It's an improvement from having to start typing again to get suggestions.

Overall, this looks polished and well-designed. Competition in the search engine space is still sorely needed.

I think the crux of the matter is that the general population don't really need much computation. They just care about meaningful data, especially their own data.

As a programmer and a technophile, computing is the first tool I use for anything. New pin? Just `tr -cd '[:digit:]' < /dev/urandom | head -c 4` and write it down. It would be more difficult for me to find a website that generates pin numbers (and it would be less secure).

I personally value the ability to freely compute. That's why I love my CLI and my text editor.

You can't easily compute on the web because the web was designed for documents (data), not computation. Maybe that's the real problem here.

I've noticed I tend to work in three passes, although not necessarily three tries.

First is an over-abstracted mess that may or not work before it eventually collapses. Brainstorming.

Second is a rewrite aiming for compactness, that could end up impossible for anyone else to understand.

Third pulls just the right amount of abstraction out of the terseness of the second pass.

I treat it like a feedback driven control-system. Too much abstraction? Dial it down. Not enough abstraction? Dial it up. Repeat until good enough.

If I stop at 1 or 2, the code is poor. If I don't oscillate, it takes more passes.

While the book is very much dramatic in tackling the subject of "psychopaths", I submitted this mainly because there's a really awesome description of a "healthy" workplace -- definitely something I'm going to keep an eye out for on my next interview.

    ...
    - Your workplace is creative, and effective. Everyone
      brings problems and ideas to the table, and solves
      them without delay or fuss. There is a lot of chatter,
      and few meetings.
    ...

As opposed to an unhealthy one:

    ...
    - The coffee wakes you, and you find the energy to start
      on the report. Except, it's meeting time.  Everyone
      crowds into the meeting room. Planning time.  Always
      the same. Your mind goes back to sleep.
    ...

There was a recent blog post about migrating from gmail to FastMail on here earlier this week.

In my personal experience, it's been excellent. I've but using it for about a year and a half now, receiving from custom domains and sending from their servers.

Their webapp is better than Google's and it's actually the main reason why I've stayed with them.

It's also cheaper than $5/mo.

I tried out CopperheadOS earlier this morning. The encryption password/pin combo was working, although I ended up flashing back to stock nexus so I can install Signal again.

It's listed as abandoned, so it doesn't look like the change is going to be upstreamed: https://android-review.googlesource.com/#/c/154841/ (also in article)

Is it just me, or is that page awfully quiet?

The community that's grown around this routing technology is Hyperboria (https://hyperboria.net/), which is mainly an overlay meshnet via the existing internet rather than an entirely new network with dedicated cables and wireless links. It's got about 700 nodes active right now (and about 1800 links), according to the awesome network visualizer at: http://www.fc00.org/

    But their stupidity persisted. They did things that
    were so wacky they boggled my mind (like putting a
    credit card number in with spaces between each
    number)...

Not allowing spaces in a credit card field is a pet peeve of mine. It's a trivial problem to solve in code, and almost nobody does it. Whether it's a space every 4 numbers (the most logical to me) or a space between each number, it really shouldn't matter.

There are spaces in the number on the card itself. Entering the number with spaces makes it easy to check if you've made a mistake in only a few glances, instead of painstakingly going number-by-number and losing your position a few times.

It shouldn't be the user's fault.
