I had no idea Roku was born from Netflix, they did a good job at distancing themselves. I think this origin story also speaks to Reid fully understanding what he set out to do with Netflix, which is to stream entertainment over the internet. From the name to this move it seems very clear that's has taken that mission VERY seriously. It is really hard to invest in something so much and when you realize it is wrong viciously distance yourself from it. very few companies rarely pivot from their original mission. The only thing I would have done differently would be to open-source the hardware and Software of the Roku, basically creating a ton of competitors but at the same time pushing the mission of streaming movies further and getting Netflix to more screens. It still worked out regardless

Delivering on the vision for multi-service mesh
My team has been hiring and training coop students for years, and it takes on average a week or two for students to become productive with Clojure. Furthermore, students with less programming experience actually have an easier time picking it up. So, I completely reject the argument that Clojure syntax is somehow less natural, it's simply different from syntax people are used to. Most people who doesn't have an existing bias pick it without any problems.
A classic. Can’t believe it’s been 9 years since I first saw that.

I wonder if there's any overlap between people who don't have an inner voice and those who can't visualize.
As such a nuisance, I insist we make this mandatory for all employees.
Do you know if they've done work on formulating the Vlasov equation (coupled evolution of EM fields and phase-space density of populations of charged particles) in this way?
Here is an earlier submission of JAX from December 2018:

https://news.ycombinator.com/item?id=18636054

JAX is pretty neat because it is effectively a derivatives compiler: it can automatically differentiate a function and JIT compile the result. This makes training in machine learning both fast and easy because gradient descent no longer has to be written by hand.
The second alternative can't be right: I know I can visualize images and I'm not confused about it :) I can picture the face of my relatives, or an animal, or my house, down to the colors. I could draw them or paint them from memory (and in fact, I'm pretty good at drawing).

The coverage of this is quite unfair.

Shkreli was sentenced to 7 years of prison in 2018. So he should be able to get out of prison in 2025. From the headline, you'd imagine he wants to somehow not serve the remaining 5 years. In reality he's asking for a 3 month "furlough" [1]:

"I am asking for a brief furlough (3 months) to assist in research work on COVID-19"

I am not sure if "furlough" is even a legal term, but house arrest is a way to serve your sentence in the US [2].

Edit: I skimmed through the paper [1]. Here's my summary:

* paper not peer-reviewed

* what was done: someone was able to provide Shkreli an HPC cluster with 512 CPU's. Shkreli did a "big data" exercise to see which compounds are promising, based on some criteria, which are presumably quite standard in pharma research

* main result: the most promising drug is clofazimine glucuronide: "we found clofazimine glucuronide to be one of the highest-scoring compounds across both screens"

* big red flag: the tables included in the paper do not actually support this statement. The compound is the highest scoring for the first screen, but did not make it in the top 20 in the second.

* worse red flag: the whole test was done for effectiveness against another coronavirus, not against the novel one that causes Covid-19.

All in all, the quality of the paper is quite dubious.

Shkreli's ask to be "furloughed" doesn't seem too scandalous to me though. He's currently in a minimum security prison. House arrest is probably not that different.

Perhaps useful for others: I had this thought as well (that my handy camera is already a high quality webcam) and had great performance on Linux with the app DroidCam [1], which includes the V4Lloopback module when you install the desktop program and presents the android camera as a webcam at /dev/video#. Connected to my computer via USB (ADB) it shows no noticeable latency. This is a bit different to all the IP webcam apps which expose the handy camera over your LAN (but that is an option as well).

The desktop app allows you to toggle the handy LED flash for better front lighting, to lock exposure, to trigger autofocus, and to adjust white balance.

I tried it first with the free version, which doesn't allow HD video. The full version is a few dollars; doesn't contain ads.

I have no connection to the developers, but am a happy user. Works flawlessly anywhere a webcam is expected (for me so far: skype, Zoom, Jitsi).

The desktop app is open source, but unfortunately not the android app. I was surprised not find an open source version of this concept (and don't currently have the time to develop it).

There always have been people who act selfishly. I'd bet you anything that it has also been this way when the Bill of Rights was written. Does that mean civil rights was a mistake? Absolutely not.
To me the implication was not that you should write more potentially buggy code to prevent the need to reboot every 50 days... but rather than you should fix the bug that caused it to need rebooting every 50 days
Remote Live Philosophy
The COVID crisis forces many wanted / unwanted changes in our lives.

However for me it doesn't look that bad..
- I work from home I don't lose 2hrs daily to commute. Salary was reduced. Others were fired.
- I do work outs daily (got gym at home)
- My children have online lessons organized by school, I'm feeling like having direct impact on their education now.
- Downside is only I cannot go outside wherever I want.
- Children have limited social opportunities
- To put it straight, I have time now for my family/myself.

The point is:
I can't imagine of returning back to the office. I don't understand why CEOs/Politicians will not changed their mindset to keep most aspects of our live remotely.

# Companies are spending millions for renting buildings
Solution: Cut it by half, and have desk shared between 2/3 people.
- It's a big savings for a companies. Instead of adjusting the salaries, why they will not do it?
- In my case, majority of the meetings are on conf calls. Only sensitive topics are managed on face-to-face meetings.
- I'm aware that it's probably bigger portion of people required to be onsite like restaurants, manufacturing etc. But for the rest employees, it will be pure saving for companies.

# Education can be in majority online. Keep current schools open but give possibility of online education to others.
Keep only sports / tools required lessons at School building, rest you can do from home. Exams at school. Easy..

# Whole remote philosophy can be applied for majority of what we do.
- Being most of the time at home will actually forced me to go outside. I will feel very uncomfortably staying at home whole days.
- Local community overall will be in better shape. Local stores more profitable etc..

I hope some CEO/politicians will read this and think about it in different perspective and not that people will be lazy at home.

That's what I think. What do you think?
In your benchmarks, KDB's max on longs takes twice as long as sum on longs. I am not able to replicate this with the most recent version of KDB (2020.03.30).

There's a marginal difference here rather than double.

Which starts to look more like your numbers.
The forging of a signature has always been a possibility, which is why witnesses are required for the important stuff.

On the other hand, you would be right in thinking that there is a somewhat anachronistic element of theater in having signatures on electronic documents.
I don't know for specific but they did point out in a couple of the articles that they are running on old mainframes. They say some are 40 years old, but it is unclear whether that is just the software or the hardware or both, wouldn't be unreasonable that it is both IME. Those old IBM machines run forever and generally as long as you keep paying IBM, they will keep supporting you. My guess is these are either the old IBM or HP/Compaq machines of the day, both were popular in government installations.

Many state and county governments still have active mainframe machines to this day and they are just as at risk as Nj is. Hell less than ten years ago I had a contract where we had to write EBCDIC files in batches for a as/400 at the county government to process overnight to update county records and we did that from a modern (at the time) web architecture with a SOA layer. We would take the output of the nightly batch processing and in-jest it to update our SQL database for the website every morning. Fun times.
Yes, the thing is stadiums in those days were massively unsafe and uncomfortabe: cramped all standing sections, no amenities, etc. Over time safety standards improved and so even if stadiums are physically the same size or even bigger, the density is much lower. The biggest football stadium nowadays I believe is Camp Nou, short of 100,000. The new Maracanã seats only 80,000 :p
Has anyone else seen reCAPTCHA getting way more difficult of late? It often takes me a full minute to find all of the tiny traffic lights hidden away in a set of low-quality images.
Regardless of how complex naming schemes you need to support, you just make it more complex and harder to query by storing tag names and character indexes and whatnot.
Free Security Tools, Resources Offered During Coronavirus Outbreak
How do you know what's fact and what's not?

A novel prize is waiting for you.
It’s sort of is actually. What really matters is the providence of the approval, the adult trail or whatever you want to call it. You are creating a record of when and that you agreed to something and the signature is an artifact of that agreement.

A signature is somewhat harder to take them and checking a checkbox and can be somewhat more easily traced back to the signatory, so it’s probably somewhat better than a checkbox.
Where are you getting this information? Can you provide a source?
It says it's free for non-enterprises .

FWIW, there's a bunch of other interesting tools for ELF, https://github.com/MattPD/cpplinks/blob/master/executables.m...

Yes and TCP/IP support in general on VMS was not great. Performance was a consistent problem. It was clearly a second class citizen for a very long time.
No, where the hell do you work? And are they hiring?
Yeah, if only we were more like the EU, where the top scientist working on this problem (checks notes) just resigned due to all the political infighting. Why can't we be more like... oh, wait.

The general solution is parametric construction. When we're building SQL queries, regular expression matchers, HTML files, etc., we're actually attempting to build a richer data structure but representing it as a flat string. Instead of concatenating strings, we can turn our original string into one where some leaf nodes are placeholders for future literal entities, which can be substituted for their actual values without fear of potential metacharacters that could be misinterpreted.

While the solution may be fairly clear, not everyone provides easy interfaces for parametric construction--regular expression engines being the one where the lack is the most distressing for me (although this is less because I need to substitute in user-generated strings and more because I want to combine smaller regexes into larger ones to make the regex easier to follow).
The webcam and video call market has stopped to improve like, 10 years ago. There's some exceptions, like the Brio, but they are worse and more expensive than a whole cheapo phone with 2 cameras. Overall we're mostly stuck with 1280x720 fixfoxus usb-2.0 crap. On the software side, things don't look better: UVC 1.5 finally does support hardware encode with bitrate control, but software support is scarce. Completely unsupported by Linux even. Don't get me started about free videoconference software and open, end-to-end encrypted systems.
Am I missing something? Is this really that hard?
I think you're confusing intent with implementation.

You're right that the implementation excludes non-malicious bots and fails to solve for malicious humans, but that just makes it an imperfect implementation of the intent: which is to differentiate malicious & good.
What I don't like is that Buster doesn't work with hcaptcha...

But I don't live in a shitty country so very very rarely do I get captchas from Cloudflare.
Tests like your first question are often poor indicators because people without an ability will develop other skills or methods to compensate. We don't just walk through life not knowing anything that's going on around us.

After being asked "How many X are there?" a few times, for example, we figure out that counting and remembering minutiae is important.

I once read an article about aphantasia which showed a bunch of blocks, and later showed different orientations of blocks and asked if they were the same or not. If you could, the article concluded that you had good ability to visually rotate a 3D object in your mind. I don't know if I do or not. That sounds difficult. But I could say right away which shapes sounded the same.
> It is an open secret among international diplomats and public health experts that WHO is “not fit for mission” (as one of them put it to me), riddled with politics and bureaucracy. Given its previous failures and the warning that was Sars, its leadership has no excuse for reacting so oddly, and so tardily, to the current crisis.

It's a start. reCAPTCHA is a notorious pain in the arse for anyone whose browser isn't Chrome and for anyone who doesn't keep cookies. I'm not sure if hCaptcha will be better, but it's hard to imagine it being any worse.
While there is an overlap in how they work technically, I think the overlap is not too big. So if you ask about a Numba vs JAX comparison here, I'm not sure if such a comparison makes too much sense.

JAX core is an extensible system for transforming numerical Python functions. This core is used to implement automatic differentiation, translation to TF XLA, etc.

Numba does not have such a generic function transformation framework - it just supports a single transformation, that is from numerical Python function to machine code.
Unfortunately VSI will not be releasing any VAX processor support, so this will leave any hobbyists maintaining vintage systems in the lurch. From what I have seen, no one in the OpenVMS hobbyist community is really upset about this decision, except for the people maintaining VAX hardware. The expectation for those using Alpha and ia64 systems is that VSI will take up some kind of opensource developer license or hobbyist license before the current hobbyist licenses expire from HP.

I’m not sure it’s what you’re referring to. This seems coronavirus specific. From the original comment I thought that inspections were suspended indefinitely.

Last time I tried using things like this, it just ended becoming a VT layering monstrosity where you had like 3-4 terminal emulators all interfering with how you expect your keyboard and mouse interactions work. It's also why I gave up trying to use tmux.

It's easier for me to just pick one terminal emulator I like and spawn multiple windows of it, ssh about and deal with the woes of TCP than put up with VT layering like mosh requires.

I love the "motivated ground-up" approach. Always mystified by the economics of educational/textbook publishing, though. I suppose for required coursework it's not unreasonable and it really looks like an exhaustive tome and educational resource. Just kind of prohibitively high $ for non-formal student. (New price is like $135, used price inexplicably over $1000)
To which I would add: typical silicon valley publication hostile to US manufacturing suddenly develops expectation of privacy on imported computers.
Price hikes in a crisis allocate scarce resources to the rich. The price gougers should be cracked down on hard.
All these things resonate with me. Brings back near murderous rage when I remember the colleagues hammering their shitty chunky keyboards, slurping tea and slamming the cup down, talking with a mouth full of food, sneezing so loud I can't believe they aren't deliberately doing it for attention, laughing so loud it must be forced, at non funny stuff, presumably to show everyone how in on some joke they are... I could go on and on. But I always thought I was the only person in my office bothered by it, as no one else seemed to notice, whereas I would be visibly annoyed. Maybe others are just good at hiding their frustration. I don't miss the office at all either.
The Coronavirus Impacts on Cybersecurity
Don't be too hasty to judge groups of people unless you are certain they don't live together.

"Think about it, one cyclist towards the front of the pack coughs and what's gonna happen?"

Probably nothing. The virus spreads more easily than some, but it's not magic. The original WHO guidance was to stay 3 feet away, not 6 feet, because even at 3 feet transmission is extremely unlikely. It's not impossible to transmit in the scenario you describe, but it's not the kind of scenario social distancing is trying to solve for.
Apples and oranges. There is no evidence that having diabetes significantly increases the risk of a traffic accident, but plenty of evidence that having diabetes increases the risk of dying from COVID-19.

What do you think "illiterate" means?
The point of a blockchain is that to edit an earlier record, you would need to edit every record that comes after (due to storing a hash of the previous block in the current block). However, it doesn’t make sense when one entity controls the entire system because if a hacker (or even an insider) can change one record, they could change all of them. Hence why a good blockchain would be distributed. Then, if one node edits the history, the other nodes will see the anomaly and ignore that node.

This is also why Git’s history is easy to edit when it’s only on your machine. But once you push to GitHub and others clone your repo, it becomes a lot harder to edit history. Yes, Git isn’t a blockchain, but it does use the idea of hashing the previous “block” (commit) and storing it in the current “block.”
For the record, I can do all of those. When asked to visualize something, I see it in my mind, as if a memory. Very detailed, full color, sometimes moving, sometimes static.

But IF asked to visualize something floating in front of me, I can do that too. It cannot ever be mistaken for the real thing, it's not a ghostly image or a hallucination, but I can sort of pretend something imaginary is sitting next to me and I can, through voluntary effort, "see" it.

Whenever I want to draw something -- or build a scale model -- I always try to visualize the end result first.
> It's a way to establish power and extract value out of what would otherwise be a more efficient company or system, since those efficiencies don't benefit you directly. The company might do better but your incentives align in a way to extract value from it

This is a fancy way of saying corruption. Twisting the system to be used for your own ends, be they strategic, or just straight-up cash-in-my-pocket, is corruption.

Operations workers can see the daily inefficiencies and profit from them, or inject themselves into processes and decisions in ways that will benefit them. Adding a layer of moron/process/politics slows or halts this bad behavior, at the cost of increased overhead and inefficiency.

Seeing that reCAPTCHA v3 doesn't use endless streams of images any more, I would guess that Google no longer benefits much from having users tag storefronts, traffic lights, buses or fire hydrants. Maybe their image recognition algorithm is past that stage.

I've bought TVs with Roku built-in, Chromecast built-in and other weird tries at streaming built-in. All but the Roku are basically worthless as the manufacturers did not ship upgrades, basically making what was a smart tv, just a tv. The Roku TV happily updates itself, and seems to have more and more channels and apps every week.
