In this viewpoint it should also become immediately clear why for-profit companies interact so poorly with FOSS communities: they are not interested in taking on unnecessary burdens and would prefer the original developer(s) contributing more free labour over having to pay for it.
Stock-trading app Robinhood scraps UK launch
Shouldn't be using Twitter at all or shouldn't be using Twitter DMs?
This is the only good book I've found on the topic. A high school textbook from 2003: https://www.amazon.com/exec/obidos/ASIN/1590704843

The show "How It's Made" is helpful. Also if you live close to any brand names that have a factory, they will usually do a tour.
Ask HN: What's some good content for a background/ambient projector display?
I have a spare projector; generic <$100 one, so it does reasonable video and larger displays, but you wouldn't want to be reading fine text off it.

I'm considering using it as an always-on background display for "ambient" purposes (more decoration than information radiator) in my home work/play/create space. Display hitting a wall off to the side, driven by a PC or Raspberry Pi, custom code if necessary.

Looking for ideas for content to display on it, beyond the obvious slideshow of random photos or generic nightclub-esque visualizations.

Don't have anything specific in mind - probably something dynamic, maybe data-driven, connected, more so than pure art. Assume similar tastes and proclivities to the usual HN demographic.

Any ideas?
This is a completely fair question and is something anyone working in performance optimization (marketing, product, etc.) should be asking themselves all the time when looking at data and finding ways to suss it out.

In the case of retargeting ads, you can run tests to figure it out. When I was doing more on the marketing side, I used to find a non-profit and then show ads for the non-profit to my retargeting audiences. That way we could test to see what kind of value our retargeting ads had vs. a completely irrelevant retargeted ad.

For the most part, the relevant retargeted ad outperformed irrelevant by enough magnitude to make the retargeting campaign profitable.

An update on Robinhood UK

Hi there,

We’re saddened to share that we’ve made the difficult decision to postpone our UK launch indefinitely. We'll be closing our waitlist and taking down our UK website shortly.

The world has changed a lot over the past several months and we’re adapting with it. On a company level, we’ve come to recognise that our efforts are currently best spent on strengthening our core business in the US and making further investments in our foundational systems.

Since we announced our intent to launch in the UK, we’ve been fueled by your excitement for Robinhood and humbled by your response. We’re sorry that we cannot deliver the product we promised you this year.

Although our global expansion plans are on hold for now, we will continue our work to democratise finance for all and we look forward to the day when we can bring this mission to the UK.

Sincerely,
The Robinhood UK Team

A note about your privacy: We will be deleting email addresses from the waitlist and removing them from our systems to help protect your privacy.
Are Captcha companies violating those laws? If so, then yes, enforce them. If not, then either change the laws or leave the Captcha companies be.
You are obviously completely wrong. But on the other hand...
Perhaps a job at a medium size non-tech company. There are plenty of problems that can be solved with small scale (web) apps everywhere, that don't need webscale levels of scalability, but are well suited for a single full stack developer
So if I'm understanding the article correctly, they didn't find much in the way of specific evidence that Russia was interfering in (say) the Brexit referendum and they're blaming it on the government and security services not looking hard enough? This feels like it's getting worryingly into conspiracy theory territory, especially given the quality of the publicly available claims of Russian interference which this appears to be referencing as proof there must be something there.

Edit: OK, I'm reading through the actual report now and it doesn't reassure. They literally reference the Buzzfeed "From Russia With Blood" piece which relies on the idea that Russia are so good at disguising killings that any death of a Russian-linked person - anything from a heart attack to a suicide of someone showing signs of depression who had made previous attempts - is in fact probably an assasination. This is well into conspiracy theory territory; it's basically unfalsifiable.

Also, it's clear from the report that they know the UK intelligence agencies had a lot of other work on their hands regarding the terrorist threat, and this consumed a substantial amount of the resources that would previously have been dedicated to Russia, so to attribute this to the intelligence services supposedly not wanting to know about Russian interference seems itself like an attempt to interfere with the UK political process.
> Why wouldn't I want deduplication though?

On a desktop?

Chances are, that you don't have many users saving the same or slightly modified version of a file on the same storage. For a single person, it doesn't make much sense.

> "You can use ZFS just fine, just turn off one of its most useful features."

ZFS has many useful features. They come with a price though, because there's no free computation (see also laws of thermodynamics). It is then a matter of deciding, which features you want or need, and are willing to pay the price for.

You obviously are not willing the pay the price for dedup (lvmvdo asks for similar price, so it is not ZFS-specific), so why are you complaining that you cannot use it? ZFS still has many more useful features.

You also have another option: add RAM to your desktop. It is cheap. Then you will be able to use that one feature.

> I hate the cargoculting on this fucking site.

Sigh. I'm actually btrfs fan, all my data are on a btrfs volume (at work, we do use ZFS though, so I do have the experience). But that doesn't mean I won't point out something that the other club does well.
> Would immersion in salt water for a few hours damage a fairing?

Yes.

They haven't been very public about how much refurbishment is required for fairings that they fish out of the ocean, but they've managed to use them on Starlink launches.
I read Peter Naur's "Programming as Theory Building" and thought it quite good.

http://pages.cs.wisc.edu/~remzi/Naur.pdf

At the time I found it I was was working where the key challenge was not so much technical as much as ensuring that simple technology, spread across a large breadth of functionality, adhered to a consistent vision of the business domain that was being implemented. The program became an implementation of the mental model I developed of the business domain itself: its purpose, its uses, and its allowances and prohibitions. The Naur paper hit exactly not only on what I had been implementing in code, but on what other developers would have to know in order to maintain that code over time.... and had the kind of knowledge that had been lost over the life of application by the time I came to be involved.... and part of why my project existed.
Welcome to your weekly sprint retrospective
“are there apps that just open a tab in your browser to show their UI?”

pgAdmin (https://www.pgadmin.org/) does that (at least on a Mac). Acceptable? Yes. Good? No, but part of that is that the web UI doesn’t feel good.

Edit: the page it opens isn’t on the Internet, it’s served by a web server that the application runs. That means it runs without an internet connection, but also (for better or for worse) that you have to update the application to update the UI.
Or grab them with a hook dangling from a C-130 like the film from old-timey spy satellites.
>> seems like they're trying to push a negative agenda on these two countries to prepare the population for a possible future more frontal conflict or war which I hope will never happen.

It's more about a restart of the cold war than a "frontal" war.

I'm not sure if you can compare Russia's situation with the US or UK. I doubt the wealthy of the US/UK are actually inteligence officers.

Of course UK/US tries to influence the elections in Russia but the warning here is that Russia is more successfull and seems to have more tools than us.
A bit more than that actually: https://www.theguardian.com/politics/2018/nov/28/uk-signific... We don't really know what the second-order effects will be, such as the brightest people moving abroad and companies permanently closing or leaving, as well as the general loss of influence.

I expect that we'll regain the 20% fairly quickly once the virus threat abates, but the Brexit loses are a permanent drag.

Anyway as I said in my comment above, we don't fully know, but we're sure going to find out soon enough.
Yes. The couple they reused after fishing them out required extensive rebuilds.

There are a lot of electronics on these things and weight is ultimate factor.
Interesting way of describing/thinking about hazard or risk analysis which is applied in many industries through ISO standard frameworks such as ISO 14971 for medical devices (but is also used elsewhere). Risk analysis complements requirements analysis in that risk mitigation plans become requirements of the system (if the risks meet some threshold).
I also don't like their theme choice, especially the "Table of Contents" is fixed and wasteful, and combined with navigation column they used 40% of the screen wide. I can't concentrate to the content because the other half is distracting.
Thanks, I took a look and I think they have a really good approach.
>It isn't even obvious why Russia especially would care about the UK electoral process

The argument I've seen is that Putin wants a weaker (or even no) EU, and getting the UK to leave is an important part of this strategy. I'm no political expert, but on the face of it this makes sense to me.
As a software developer I have been doing this exact thing for the past twelve years: think of all the possible reasons why something can fail.

The downside is that I have trained my mind in such a way that it is difficult to turn it off outside of work and it is influencing my personal live negatively.

(or maybe I'm just wired to be a doom thinker and that is what makes me a good software engineer)
One of the startup I worked for in London was using Adyen. That is to say they are not limited to enterprise customers.

We were processing a few millions a year at that time, which is quite small by enterprise standards. No idea how much volume it was years before when the company started using Adyen, I imagine not a lot.
> errors ... bracket imbalance in comments

Not sure where this is coming from. Elisp doesn't error on anything in comments.
Yeah a direct inversion doesn't seem to work. I think you invert the idea but with the premise that you don't want to do it.

So instead of: How do I decrease adoption?

You think: How do I avoid decreasing adoption?

I think this works anyway. Another example:

Goal: Fly to Spain

Question: How do I fly to Spain?

The inverted question should not be "How do I not fly to Spain?" (answer: get put on a flying ban or don't buy a ticket) but "How do I avoid not flying to Spain?" (answer: pick a date and book tickets)
That’s weird - I call it “letting it ride” and “never leaving a hot table.”

Gambling is a word used to describe anything beyond your own acceptable risk tolerance.
I did start similar things over 10 years ago. Where I am at these days is just text files ( markdown ) nested into folder structures. I've found this the most sustainable for quite a few years and it's been super useful. Main thing is, do whatever, as long as you find it easy to sustain.

> seems like they're trying to push a negative agenda on these two countries

Ignoring media manipulation seems like a way to allow instability to be promoted. We've seen Russia stir up gun ownership and racial issues in the US, and Scottish independence in the UK.

Regardless of your political stance it's important be be aware there are outside interests manipulating things to cause maximum chaos.
the exact same story a year later says 6.7%: https://www.theguardian.com/business/2019/oct/17/uk-lost-gdp...

> We don't really know what the second-order effects will be, such as the brightest people moving abroad and companies permanently closing or leaving, as well as the general loss of influence.

so what do you think they were modelling? nothing at all?

> I expect that we'll regain the 20% fairly quickly once the virus threat abates, but the Brexit loses are a permanent drag.

a reduction in growth is not a overall loss, sorry
The power of whataboutism is the change of topic so it isn't adressed. Like talking about China when the topic is government accessing your data.

So stripping whataboutism, your argument is basically reducted to "the FBI accesses a source of info but that isn't bad because of oversight".
US Withdraws from World Health Organization and Democrats Are Losing It
Never considered support role to be honest. Maybe it feels a little inferior after having those degrees I guess but that’s my own bias. I did think of like a product management role at startups but they all expect you to have pedigree or previous work ex in similar role. Catch-22!
Ask HN: Could we build an open, decentralized version of GPT-3?
I find it somewhat scary, that the most advanced AI is only available to whoever gets selected by a single authority.

From what I read, the model has 175B parameters and therefore cannot run on a normal computer.

Could we build something like AI@Home where everyone contributes some memory/processor time?

Getting up to some hundred GB of memory does not seem too hard this way.

I guess the hard part is creating a decentralized NN. Not sure how much research has been done on this already.
You miss the forest for thr trees Gentlemen.

The article is about the fact that UK intelligence and government both know that Russia interfered in referendum on the side of Brexit. Obvious leave won, and if they were to find any concrete evidence of this interference, it would damage credebility of UK Leave even further, on top of existing breaches of electoral law and populism / trumpism.

"There has been no assessment of Russian interference in the EU referendum and this goes back to nobody wanting to touch the issue with a 10-foot pole"
This is hilarious.

For me, it has made driving difficult. I think of everything I can do incorrectly and everything others can do incorrectly. I think of all possible events happening on the route. On the plus side, I am a careful driver. On the negative side, I _really_ hate driving.
Of course, "strong opinions weakly held" is a refactoring of the scientific approach to knowledge. Karl Popper taught that scientific hypotheses necessarily must be disprovable. Hypotheses that aren't disprovable (falsifiable) are useless in science.

Insisting on falsifiable hypotheses is a difficult personal discipline, not to mention collective discipline. "Nothing is true unless it might be false!" Wait, what? How can a company make decisions based on that sort of epistemology? How can a government set policy? It's much easier to make decisions when we have the illusion we're sure about the facts.

Maybe the only sensible path is to hold all our opinions, personal and group, lightly.
Well, there's at least one obvious motive: getting the EU a little more busy with itself so it may not have enough energy for other matters.

The mess it plunges the EU, having to deal with this one huge internal issue, rather than having more resources on other external topics (such as, what's happening on the border region with Russia, with the Middle East and with Africa).
> “Why does the framework not work very well?“

Framework? That’s just silly. It’s a turn of phrase that helps you change your attitude or approach a problem from a new direction.

“If at first you don’t succeed...” I suck. I’m never going to try again! Haha.

I didn’t know the origin of the phrase, and that’s a testament to its creativity.

As a life long learner, I found it useful in ways not related to the origin story. It helps me to overcome imposter syndrome.

I know a little bit about a lot of things, and a lot about a very few things. And I love solving problems with design thinking. Go for it. Feel confident about your knowledge if you have done the work, but know there are others who know more.

All that gets nicely summarized by Strong opinions, weakly held.
I think this might be due to a difference in optics. What you see as 'asking for a second or third opinion' might be seen by others as lack of independence, leadership and ownership.

Mostly everywhere senior developers are expected to self-manage and make difficult decisions on their own, unprompted, and just present working solutions to the business. It's okay to take time on this - solving it on your own, consulting literature, peers, etc. But looping in management into technical decision making might make you look like you can't make decisions on your own, or need micromanagement. Management, business and product care about things being done - not technical approaches or having to choose between multiple solutions.
I would love to I suppose. Sort of like a mini-cto/dev of a small non-tech company would be ideal. Tough to find such opportunities. Any ideas where?
Don't believe the dark matter hype
They didnt find because they avoided looking very hard. Because uk leave vote is such a sensitive issue politically.
Gamepedia was bought by Fandom too, FYI.
Machine Learning for a Better Developer Experience
Is the link in the blog post a good place to start? (https://fs.blog/mental-models/#what_are_mental_models) or do you have an alternative suggestion?
While I fully agree with this sentiment generally, I wonder what people think of NPR and WaPo in comparison (both give much less choice than Engadget).

I seem to see this complaint on every Verizon-property article posted, but NPR and WaPo get excused?

I wonder is it just a UX difference?
It is interesting because it lets you reflect on asine practices. If this level of distrust by government towards citizens is accepted and normalized because of terrorism and subjective security needs, don't cry if people think government wants to intentional feed lead to your kids.
In places like Japan you are expected to wear a mask if you're sick, so there's no reason that shouldn't become standard in the West.

More important could be that workplaces require staff to either stay home and not infect the office when they have the flu, or wear a mask if they have to go in.
They just have a very (over)zealous locale detection system that tries to show you a language localized page based on your browser's language priority.
I think its very difficult to do that. All media articles on snowden and assangle typically tall about their persona rather than illegal actions they've uncovered.
This is awesome. I ended up just removing random bits to make it look wrong, but somehow it always ended up looking pretty stunning. I think the shadows also add a lot to the scene.

I also made a pretty good-looking two layered structure with it: (pic https://ibb.co/vVbtG52)
The article gets it right, but "man muss immer umkehren," is better translated as "man must always turn upside down", "inside out," "turn back" or "reverse" depending on the context.

In Afrikaans, "omkeer" is derived from the Germanic umkehren and would be used as changing direction (in a military sense) or upside down as in 'leave no stone unturned.'

Strangely, nowadays I would refer to inverting your trousers as "binneste-buite" (inside-out) or "uitkeer" in Afrikaans: roughly 'about face'.
This is the problem with a good percentage of advice and life/career hacks on HN -- they're always spoken of in the early, idealist stage. Before the reality has set in. Before the downsides have made their presence known.

I've been in a number of firms with wiki knowledge systems. In 100% of the cases it was a wasteland of derelict knowledge that had been abandoned and was usually much more destructive than beneficial.

No one was going to undertake the process of keeping it up to date, and at the same time the emergent organization/structure of information was constantly evolving, and wikis are terrible at evolving with that unless you literally have people whose sole job is making templates deciding on the ontology, etc.

Similarly, countless people have tried to organize their lives into tools like wiki. And in the early days it seems magical. I suspect the failure rate would be somewhere barely under 100% at the one month mark.
This assumption really doesn't hold though if you look at a couple different language standards
Just noting that your MNIST demo on https://www.gradio.app/ seems to have a bug.

If you create a small zero it is classified as a 9. Or perhaps it is overly sensitive to line width? Drawing large circles counterclockwise with the small pen seems to be misclassified too.
> Also, I work for someone who is color blind.

Jethrains also does things with outlines, etc - a bit more limiting maybe but worth considering.

But yes, we much make sure we don't end up causing problems here - what about someone using a text-to-speech tool?
Apparently thats been considered, and you still might see another company like electron try it. It's just a bit harder to do safely and some other limitations.
It was actually far worse for the Lorenz (Tunny) traffic. The wheel patterns - the equivalent of the key in, say, AES - were changed quite infrequently early on. The five χ-wheels (in Bletchley parlance) were only changed monthly, while the five ψ-wheels were changed quarterly. While the two μ-wheel patterns were changed daily, there was little consideration given to what those patterns actually were. The χ-wheels generated the first of two sets of bit patterns to be XORed with the plain text; the ψ-wheels generated the second set. That would have been fine, except that the two μ-wheels together determined whether or not the ψ-wheels advanced - μ1 advanced on every keystroke along with the χ-wheels, μ2 would advance only if μ1 was a 1, and the ψ-wheels advanced only if μ2 was a 1 - and bad patterns on the ψ-wheels would mean that the ψ-wheels would be essentially frozen for extended runs of the message. What was meant to introduce a sort of dither to make it harder to determine how the key was being generated became the Achilles heel that highlighted the mechanism. (Not to take anything away from Bill Tutte and the rest of the crew at all. There was still a lot of cleverness and tedious attention to detail involved.) With a month of life on the χ patterns and three months on ψ, depths and near-depths on the message settings (the nonce or IV) were absolute killers. Later on, all of the wheel patterns were changed daily, and the μ-wheel patterns were verified for short stall lengths, but by then the machine's mechanism was well understood, pattern-derivation methods had been devised, and Colossus had largely eliminated the χ component from the puzzle.
Elisp is popular, but not likely through any strength of the language. Emacs' rich history of people writing crazy extensions is just so compelling it can't be avoided.

There isn't really an argument for why a text editor needs its own different brand of lisp vs. using Common Lisp with a dedicated library for the Emacs interpretation of how text works. It only ended up this way from inertia. But it is nevertheless extremely telling that the only major implementation of Elisp is Emacs.
Or you pay noting and use QT.
It currently is, but I can imagine that changing if it were to be as widespread as email, and anti-spam measures are going to take the instance toots are coming from into account.
