OpenBSD/arm64 on Apple M1 systems
|
Happy to see this! I run OpenBSD/arm64 on a Pi 4 and am posting this from OpenBSD on an old ThinkPad. Great OS all around, and it's always nice to see the current version running on both old stuff (this laptop from 2012) and cutting-edge stuff simultaneously :)

Introducing PyScript (summary of PyCon keynote)

i hope that the screen is as modular as the rest of it. i am looking forward to swapping an aelectronic paper display, black and white or color.to the people writing off the keyboard, i don't think you know what you're talking about. it takes maybe a day to get used to this layout, and ortholinear is much more logical and comfortable than what most people are used to.the people complaining about the space bar are the most confused. wide space bars ourr a waste of space. you don't touch the whole thing anyway.some people have commented on shortcuts being in the wrong place, but this is also flawed thinking. for copycut and paste you can use your right thumb to press the modifier key or control.i just hope this is not too big to use with just two thumbs. my dream device is some keyboard wider than a blackberry style one. i miss my sidekick.

Debian's Chromium changes default search engine to DDG
|
I don't mind the idea of changing the default search engine to DDG, but not in a stable release, do that in testing.It is opinionated choice, not a bug fix, and definitely not a security update (severity: wishlist). I don't have a problem with maintainers having opinions, but on a stable distribution like Debian, I would have preferred they expressed them before the freeze.

What’s so great about functional programming anyway?
|
I write JavaScript all day long for my personal projects and my clients. But functional programming, at least as I see in this article, looks like a lot of extra work to do something simple.I am sure I'm missing something here. But I don't understand why I would ever need to use code like this. My clients and I value shipping code as fast as possible. This just looks like it would turn my 1 hour job into 2 hours with not much benefit.Anyone who doesn't have a lot of experience with JavaScript or functional programming will have a really hard time reading and understanding my code. I've been coding for a long time now in JavaScript but this looks like a lot of complex code to me for simple tasks.I want to love functional programming because everyone is talking about it. But what am I missing? What would be the benefit of recreating a language inside a language?

A software change allowed FTX to use client money
|
Programmers should have a moral and defensible right to object to something that severely harms those who use their systems. Saying he was just doing what he was told fails to account for the fact that had he said no and flagged this as immoral, some customers may have their cash… maybe. Worst comes to worst he is fired but working at that level you’ll find a job in 5 mins and have sufficient capital to weather the storm. I’m a strong believer that ethics and basic philosophy should be taught as part of a cs curriculum. For precisely events like this.

Popular Subreddits are organizing a strike on 2023-06-12 b/c high API prices
|
I'm perplexed as to what to support here. For someone like me who brazenly hates Instagram, FB, Snapchat kinds of social media, Reddit is a gold mine of wisdom, advice, and content, if used appropriately. And the best way to use it was through third-party apps like Relay, Apollo etc.The eventual loss of better user experience is saddening, but I'm not sure I fall into the category of not using it at all, because it's where I learn about a lot of useful stuff on life, personal finance, frugalism, unfiltered review of a product I haven't used yet etc. I hope this decision doesn't break the site.

Shreddit is a Python program to remove all your Reddit comments

Does this also unlink the comments from your profile?I see that the README mentions a distinction between edits and deletions. But it’s not super clear without examining the code.From what I’ve seen, only mods can permanently delete comments which also removes them from your profile. If you delete a comment, then it’s still visible in your profile. If you edit a comment to be blank, then the blank comment is visible in your profile.

Launch HN: Radical (YC W23) – Autonomous high-altitude solar aircraft

What is the economy vs LEO satellite constellations? What is the expected equipment payload and cost of the 110ft wingspan prototype?

Petabytes on a budget: How to build cheap cloud storage
|
This made the Beowulf list yesterday, and below is what I wrote in response:"Seagate ST31500341AS 1.5TB Barracuda 7200.11 SATA 3Gb/s 3.5″
Aargh! Should be definitely substituted by 2 TByte WD RE4 drive.Today I've built a 32 TByte raw storage Supermicro box with X8DDAi
(dual-socket Nehalem, 24 GByte RAM, IPMI), two LSI SAS3081E-R and OpenSolaris
sees all (WD2002FYPS) drives so far (the board refuses to boot from DVD
when more than 12 drives are in though probably to some BIOS
brain damage, so you have to manually build a raidz-2 with all
16 drives in it once Solaris has booted up). The drives are about
3170 EUR sans VAT total for all 16, the box itself around 3000 EUR
sans VAT. I presume Linux with RAID 6 would work (haven't checked yet),
too, and if you need more you can use a cluster FS.Maybe not as cheap as a Backblaze, but off-shelf (BTO) and
you get what you pay for.

Light Table is in YCS12

OK now, this is a whole new business model and I like it. Early supporters pay for the demo and get a t-shirt. Later supporters pay for the continuing refinement of the demo and get a t-shirt. Later supporters pay for the demo and get a t-shirt a mention somewhere.When the demo is awesome (but not open to the public) and also the market can be assessed based on early support, someone (who saw the latest demo and the early support) pays for the rest, but what they get is a cut from any potential future cash flows. Now, this, is, neat!!!Incidentally, this is the problem with Kickstarter - if you want money, don't give me a t-shirt, give me a part of your future profit. Then people who back bad ideas suffer and people who back good ideas profit. As opposed to the current model, where everyone gets a cheap shitty t-shirt and the world gets another worthless r&b record that nobody wants.

What The Rails Security Issue Means For Your Startup
|
Code execution while deserializating / parsing data is my first and uttermost concern. Nowadays I'm in Clojure land and it's still not entirely clear as to what I can and cannot do and what the language as to offer me so that data doesn't contain rogue code that is going to be executed.In Common Lisp, for example, as far as I know you can set a flag so that the reader is set to "no evaluation ever" (if I understand things correctly) and, hence, if you're not using eval yourself specifically, nothing is ever going to be evaluated.But how would that work in Clojure? And what about other languages? Ruby? Haskell? Java? C#?I think the ability to execute code became the most important security issue (more than buffer overflow/overrun which can now be prevented --even sometimes provably impossible to happen thanks to theorem provers).More thoughts should be put into explaining how/when a language / API can execute code and how it should/can be used to prevent such a thing from happening.

Simple Minecraft Clone in 580 lines of Python
|
Software has a habit of becoming exponentially complex as the featureset increases, so I am not that impressed by small code if you cut features aggressively.To prove a point, I wrote a minecraft clone in about 60 lines of code (10x less than the Python version). It cuts a few more corners (no textures, no gravity), but has the basics of world generation, rendering, and most importantly, adding and removing blocks in front of the crosshairs to build (see the little arch I made in the middle):http://i.imgur.com/ZZWFkXn.jpgIt's written in Lobster in about 1.5hrs, which is quite similar in features to Python + pyglet. Yes it uses a few high level calls like simplex() and camera_FPS_view(), but these have been part of the Lobster standard library for a while, so I believe that's fair. All code I created for this demo are in that screenshot.

Heartbleed should bleed X.509 to death

Rather than all the engineers and tech-minded people here naysay the idea into oblivion, I think it's worthwhile that we encourage designers to take an earnest stab at this problem.The complaints here are basically "w.o.t. is not usable", but that's basically what the author said. He therefore also indicated this is as much a design problem as anything else. That's a useful insight we shouldn't dismiss, at least not until some thoughtful, imaginative designers have actually taken a crack at it.

Everybody saying "lawyer", ignore, that's expensive and bad advice, you already know what the lawyer is going to say, lawyers are incredibly cautious and not particularly flexible or business savvy in helping you, all you'll get is a bill and no help with anything except what you already know couched in terms of a lot of statements designed for future "I told you so"sFire: probably, but not because this infraction was so bad or impossible to deal with (the victim herself said so) but because the guy appears to be a bad egg, just really bad judgement and other employees or customers might not be as adept as she is at dealing with it. So, unless his contract somehow protects him, or he is God's Gift to Business Development and your company is down the tubes without him (in which case you'll still need to figure out a way to head-off/handle his future infractions (promote her above him?)), you don't need to spend more time dealing with this.

Is AI Riding a One-Trick Pony?
|
Funny thing, the problems with deep learning sketched in the article are pretty much exactly the same in nature as problems with machine learning 10 years ago (when other algorithms such as SVM, LVQ and others outperformed NNs for a bit), except of course that the examples of what a ML algorithm could do back then were much less impressive.That lack of real-world knowledge, understanding and conceptualisation feeding back on itself has always been a big unknown roadblock standing in the way of AI. And of course now, with the modern and improving impressive results of deep learning, there appears to be less and less cool stuff to solve before we finally have to face this roadblock.But it's the same roadblock.But, maybe the advances in deep learning will provide some tools to chip away at it. That wordvector stuff seems promising, if it can do (Paris - France + Italy) ~= (Rome), that's a good stab at realworld knowledge, it seems.I used to study Machine Learning at university until 2009 (until personal circumstances forced me to abandon it). But even after that, when I read the first papers and talks about deep learning (back when it was still about Boltzman networks) I got very excited and have been following it closely. Except for the part where I haven't yet played around with it myself apart from some very tiny experiments :) (I only recently acquired hardware to have a stab at it, so maybe soon. The libraries available seem easy enough to use, and many of the concepts I learned in ML are still applicable).

Counterintuitive Properties of High Dimensional Space
|
A simple observation that makes these properties a bit less counterintuitive is that the diameter of an n-dimensional unit cube (Euclidian distance between two opposite corners) is √n while the diameter of a unit sphere is always 1. So as the number of dimensions grows, the diameter of the unit cube can become arbitrarily large and the corners of the unit cube move further and further away from the unit sphere.

It also described the author's motivation as vindictive. But NPR did not contact the alleged author.So NPR did NOT contact the author and then described their motivation. It's good that they retracted this article but how many times have they released similar articles with similar total disregard for the truth?

IBM purged ‘gray hairs’ and ‘old heads’ as it launched Millennial Corps: lawsuit
|
Age discrimination in technology is alive and well, flourishing under the veils of "over qualified" and "culture fit" and "no experience with the xyz product".
I have had many great phone interviews. On site, in the presence of hiring decision makers, while I look like a typical white corporate employee, the gray hairs blending in with brown are visible enough for the comments such as, "this role may not be challenging enough for you", and the end result is being over qualified. Not too old for them, just too qualified. Makes everyone feel better.
If and when I need surgery, I hope my surgeon is overqualified!
But thecreal focus is on tools. "Do you have x years experience with the xyz software product?"
I spent at least a decade of my career evaluating new technology...And implementing some of it. A tool is a tool. But what is the process? What is the purpose of the tool?
A person says they have 5 years experience with a Milwaukee hammer. That's what the job req says is required.
This person gets hired because the person with 7 years weilding a Craftsman hammer doesn't have the Milwaukee hammer experience. But what is the purpose?
In the end, the 5 year Milwaukee experience person gets the job but still can't hammer in a nail without bending the nail. And places nails with no regard for rhe building code.
Experience is not about the tool, but that is not what today's HR hiring/vetting process is about.
ISAM, VTAM, DB2, Paradox, Oracle, Sybase, SQL Server, nosql, hadoop... tools. Third Normal Form? Data dictionary? Index optimization? Processes not addressed by a specific tool. Similarly, does memory management enhancements make the C coding language that much different?
But I digress.
Hire the experience with the process, not necessarily with a tool. Especially the "flavour of the year" tools.

Level Design Patterns in 2D Games
|
I really enjoyed the Commander Keen series. But also Duke Nukem 1-2 (2D), Crystal Caves, Bio Menace. Or Game of Robot.I always found that some of the platformer games of consoles, like Super Mario, Donkey Kong, had much more simplistic and kind of boring levels. You did not had to collect keys to enter doors, or do other more complicated things, but basically it was mostly dexterity.This aspect comes a bit short in this article, I think. To me it was always kind of crucial, how much such puzzle element there was in the game, whether I liked a platformer game or not.

Raspberry Pi 4 not working with some chargers
|
The Pi people are good folk - all that is needed is to run the USB 3 conformance tests and report back the results (both as USB PD sink and source). Better to know the knowns than have a enthusiastic fan base find them and we get into discussions like this!I'd also recommend they put up a compatibility table of power supplies on their website in time - probably cables as well! Its a good opportunity to collaborate with the Google engineer who has been spending his non-core hours on the USB-C madness.

Performance Matters
|
This sounds like a clear case of consultant software. The people building it won't be dogfooding the result - at most they'll be clicking around the UI on their powerful desktop machine and patting themselves on the back because it responds in less than half a second. The requirements will be vague, because getting performance requirements anywhere beyond stupidly vague "performant on modern hardware" or some shit requires real expertise in UI design and will cost real money to build, and UI designers won't be involved in the details until the contract is signed."Premature optimization" in reality is a vacuous phrase, because premature anything is bad - it's right there in the word! (Insert joke here.) The problem is that most developers (myself included in many cases) are just not qualified to say when it is premature to optimize, because the requirements do not state anything meaningful about performance.If you think this is overly pessimistic, I would encourage running pretty much any Android app or opening any major website on a 2018 or older smartphone. It's pretty obvious developers don't know how to build software for the probably 50% or more of customers who don't buy a new top-of-the-line phone every year.As for performance guidelines, have a look at Jakob Nielsen's amazing evidence-backed UX guidelines such as Response Times: The 3 Important Limits[0]. The ones which should stick are that 0.1s feels instantaneous (probably not when using a scroll bar, but that's another matter) and 1s is the limit for not interrupting the user's flow of thought. In other words, if anything your program does takes more than 0.1s to respond to user input on the target hardware that should at least be acknowledged and prioritized (maybe at the end of the backlog, but at least then it's a known issue).[0] https://www.nngroup.com/articles/response-times-3-important-...

MyPayrollHR CEO Arrested, Admits to $70M Fraud
|
I read this article, the previous one, and this blog post that explains ACH: https://engineering.gusto.com/how-ach-works-a-developer-pers...This is such a fun and interesting rabbit hole. And now I get how the whole thing worked from a computing perspective. I'm now just confused as to why the scam broke down the way it did. From my understanding, it seems that Pioneer was going to freeze his account (and they did). So in order to fix that issue, he temporarily diverted funds to his Pioneer account, settle debts(?), and continue trying to get money to cover the money he now owed to Cachet. But that doesn't make sense, does it? Because this fraud was going to be detected instantly (most likely) or ~3 days later. But that is nowhere near enough time to settle debts with Pioneer and get enough money to cover the Cachet debt.It seems to me like it was an extremely long Hail Mary that was likely never ever going to be successful.

U.S. immigration policy has been a boon for the tech industry in Canada
|
It's remarkable that the United States can have the highest number of immigrants for any country by a wide margin and still be in this position.https://www.pewresearch.org/global/interactives/internationa...Over 44 million residents of the US were not born in the US, as opposed to 8 million in Canada. As a percentage of the population, that's lower than Canada, but by weight of sheer numbers, the US shouldn't have any problem with this.The US takes over 1.2 million immigrants into the country every year, we just don't have much of a skilled immigration system - ours is largely based on family reunification. Canada and Australia, on the other hand, have a points based system that favors immigrants with education and skills.I actually do blame the high tech industry for some of this. I just don't think it's a "bug" that the US system was largely based on a very indentured approach, where high tech companies got to decide who is allowed into the US and the circumstances under which they are allowed to remain, with long, grueling waits for a green card, where a would-be immigrant was beholden to an employer (called a "sponsor") and could be fired and deported at the employer's pleasure.Facebook, Google, Apple, all the big companies - you see, what they wanted was a freer, more open system where skilled immigrants got to choose what they'd study, where they'd work, what companies they'd work for, and even whether they'd work in tech in the first place, in accordance with their own personal values and interests and market signals such as salary, cost of living, and work conditions.That's what google and Facebook wanted. Unfortunately, all they could get was an visa that they bestow and control, putting them in a position to determine micro aspects of a would-be immigrants life.Right. This utterly corporate self serving H1B guest worker visa system that undermines markets and is an affront to freedom did terrible damage to the public perception of skilled immigration.Want to be clear, I don't blame anyone for working on an H1B, this wasn't your choice, and it was your only option. Don't blame you for going to Canada, either. But I just don't buy it from the corporate lobbyists. This was hardly a bug, to the companies that make heavy use of the H1B, the control over the worker's right to live int the US is a feature, and they lobbied hard for it.

Small mail server best current practices

Very interesting article, but hosting my own email is a fantasy for me that I will probably never spend the time setting up and maintaining. ProtonMail does everything I need in an email service, with FastMail and Hey (which I only tried for a week) being excellent runners-up.Sorry for going off topic but everyone should host their own web site(s) and stop putting their content on other people's platforms.

Launch HN: Noya (YC W21) – Direct air capture of CO2 using cooling towers
|
Cooling tower "drift" is an air emissions PM2.5 permit matter in California. What is drift / carryover of the unsaturated and saturated material? Typically it happens associated with entrained water droplets; that's why e.g. salt water can't be used (among other reasons). More to the point, what fraction of the total capture energy are you eliminating? If you're changing evaporative efficiency in a forced-draft tower, you're incurring additional fan power or worse, increased fuel use in the process for which cooling is taking place. How do those balance against the fan power of a separate capture unit? But maybe the biggest matter: in other capture technologies, the heat of dissociation/regeneration and the compressor power to deliver to sequestration are very large. What change to the total energy budget are you proposing? When you're at scale, what fraction of total capture needed could be delivered this way?Does putting CO2 in a bottle keep any CO2 out of the air for as long as a month? Removal times of hundreds of years are required for the capture process to contribute to climate.
