I would say that learning mathematics is virtually impossible without a teacher. Like, would you try learning Karate without a teacher? How about if you get with a bunch of friends and you all try to learn it together? No way.

Even the professionals try to find someone to learn a new concept from. There's something about mathematical writing that is too fragile/brittle for wetware.

One other strategy: I've noticed the really smart (arrogant?) people just don't bother reading new mathematics, they re-invent it themselves. It's actually worth trying if you can stomach it.

If you have invested a lot in ICE, and it is a current competetive advantage, there are two choices: 1. bet on an ICE future or 2. bet on an electric future.

You make more profit in the former, since you can use your hard earned competitive advantage. You make less profit in the latter. It might even be that you have little competitive advantage in the latter one.

Now, based on this, maybe it makes sense to only bet on the first one. If the other future realizes, then you just go bankrupt. Margins are thin anyway, so it's not possible to cover all bases well. You might have a token effort towards electric cars - show some fancy concepts and meanwhile in reality slap on some bought tech in existing ICE cars.

If you're an upstart, it makes sense to bet on new technology where others don't have an advantage. Again, if the new technology doesn't really happen, you just go bankrupt.

In reality, since Germany has good engineering education and lots of relevant suppliers, there should be electric car startups in Germany. Where are they? IMO that's the more interesting question.
I'm always bit sceptical of "our rewrite in new language is quicker" stories. If I were to rewrite something in the same language as v1 t would probably be quicker.

Actually that's not true, I'd probably get bored and then just ry to get the damn thing working as well as v1 used to and then go on holiday without optimising.

Since I happened to need to send & receive a fax, but didn't like to commit to a longer subscription plan, I made this website for doing that: https://5dollarfax.com/

I had a plan to promote it by writing a deep blog post about the contents of a fax handshake, and got pretty far into it, but at one point it required some signal processing knowledge I didn't yet have and the post languished.
To be fair, the vulnerability was fixed quickly. And in the end it improved the security of Matrix and the governement application. I prefer this to a closed-source application developed internally, without communication on security vulnerabilities.

Far from me to defend every UI of every development tool out there but I think statements like these, and their illustration, could benefit from some explanation for those of us who are not designers:

> We coders still put up with horrid UX/UI when programming.

which is illustrated with a screenshot from Visual Studio... .NET 2002, I think, judging by the application icon?

Setting aside the relevance of a 20-year old screenshot, what exactly is wrong with that interface and what makes it horrid? I mean it definitely had its quirks but:

- It's spectacularly compact, certainly way better than anything I've seen in the last five years. We could display an UI builder and the associated code on single 1024x768 screen and work on it semi-comfortably. "Beautiful" UI/UX, as understood today, is so cluttered by whitespace (oh, the irony...) that it's barely usable on a 1920x1080 screen. A similarly compact interface on today's huge screens would be a dramatic productivity improvement that, twenty years ago, we could only dream of.

- You could easily access any function through textual menus -- no hamburger menus, no obscure, monochrome icons. Granted, the toolbar icons were a pain, but the way I remember it, most of us either disabled it straight away, or just populated with a couple of items that were of real value and which we knew well.

- The colors have great contrast, the whole thing is readable even on a very poor-quality screenshot that seems to have been actually downsized.

- UI items have enough relief and/or distinction that it's clear what you can interact with and what you can't (maybe the item palette from the diagram editor is an exception, or at least the screenshot makes it look like one, but virtually every program in that era made it look like that so it wasn't so hard to use).

So what's wrong with that thing?
Changing credentials is helpful if you assume they're compromised every once in a while. These days if a unique and random password is used for each service and/or with 2fa enabled, that assumption is not that great anymore. Adding to that the fact that most people will just add "1" or the current year at the end, it makes updating the password much less useful - it will only stop completely trivial malware.

Signal turned over everything they had on this user (which was two time stamps: user creation and last access), and fought the gag order to be able to publish the subpoena and the response. Signal would have to be pretty stupid to lie to a federal court.

Think what you want, but Signal doesn’t have any metadata to turn over.

Unfortunately, the JIT described here cannot be be used in an app submitted to Apple for review, which is required for all apps distributed on the App Store or via TestFlight. By the way, osy (who is also in this thread) is the author of UTM, so you'd want to ask them about project management decisions like these. I just submit patches :)
148 Billion Euros might sound large, but in terms of governmental spending it's pretty small (especially on a continental scale) and there, of course, other things competing for this money.
You misunderstand this problem. Doing group chat where you do a massive rekeying of all participants every time someone joins doesn’t scale, but it is secure. Signal doesn’t practically support large groups like Telegram does (although telegram is unencrypted as a result).

I can assure you that large secure groups with strong cryptographic guarantees and evolving membership lists is unsolved.

I'm a designer [0] and an engineer — you'll take my shell from my cold, dead hands.

There are two issues here:

a) Designers trying to simplify everything beyond usefulness is a good instinct gone haywire. Simplification helps, but without an understanding of accidental complexity versus essential complexity, one is bound to end up painted into a corner with no flexibility left in the app. Few designers understand this, and those who do got it the long way round — by working on products that have a lot of essential complexity, like AdWords, and by repeatedly fighting those battles

b) An engineer's operating environment, OS, IDE, shell, terminal, is a reflection of the inside of his or her mind writ large. Like every Jedi has to build their own lightsaber, every engineer has to go through this pain of building out their weapon, because one's workflow is how one thinks, how you look at the problems at hand. No UI designer can help with that.

The Dutch government is also often terrible at managing IT projects. It seems an industry has evolved to game the public procurement rules required by the EU. Those companies just leech money for never-ending IT projects that tend to be over budget, over time, and working poorly.

A lot of technologies are getting way more complex and confusing than necessary. Just look at the market of time management. Tonnes of tools, software, coaches, websites, books, etc. You name it.

>>Promoting the app, however, could antagonize the law enforcement community.

The margins of law enforcement and intelligence can be blurry, but to the extent that they're antagonistic towards private communication as a whole... "law enforcement" is kind of a euphemism. The article should have said "could antagonize the intelligence community," whether it's police or whatever.

Over time this "antagonism" is growing, because intelligence is increasing its reliance on these data sources.

>The license fee costs £154.50 a year, or £52 if you only have a black and white TV (lord knows how given we're now 100% digital), but the government pays it for you if you're over 75 years of age.

The government stopped paying for it years ago, and forced the BBC to give out free licenses in order to hurt the BBC.

> Also, AMO addons are code-inspected by reviewers, unlike the chrome store.

Are they still? Last I remember they started auto-accepting addons which passed the automatic tests and just maybe review them at a later point. Which could happen anytime between tommorow and next year. In the meanwhile the unsecure addon is floating around, endangering users.

There now is also this message:
"This is not a Recommended Extension. Make sure you trust it before installing."

This kinda indicates the user is on it's own with such extensions, and there is no review at all?
Yes, things should be written in a simple way, but excusing the issues with the program with "Well, the developer should have written it simpler" does not resolve the problem, just shifts the blame.
> The signal servers don't even have that bit of metadata. See [1], they only store the last time that a user connected to the server.

Note that it's what they claim at least. It's not verifiable client side, and to be honest, it's hard to come up with a scalable protocol where this is the case, but you should still not repeat their claim as a matter of fact while in reality we only have their word that the code actually matches what's deployed. And even if they don't store anything, AWS could still provide interested entities access to the infrastructure to capture what Signal doesn't want to capture. Yes, features like sealed sender are awesome and are an important step, but the service still gets ip addresses, which do provide hints about the sender. Again, likely Signal doesn't store ip addresses but people with access to their infrastructure could.

Furthermore, Signal's encryption doesn't help against people storing all of Signal's traffic and waiting until attacks on crypto algorithms become practical (quantum computers, theoretical progress on attacks). Some secrets become irrelevant with time, others increase in value. The best defense is never having the message leave your country's network in the first place.

Make an effort to not be productive most of the time and draw a clear distinction between work and leisure. Even if it feels counterproductive, not being productive and just enjoying yourself with non-tech hobbies or non-growth activities, likely will refresh your mind. I used to be like this; work 40hrs, then work another 20-30hrs from home. It used to work, and damn was I productive and enjoying it. But over the years that was no longer the case. Working on a better work/life balance and drawing that distinction did help me get back to that state of joy though.
This is a very fascinating discussion. NRK, the Norwegian national broadcaster also does this. NRK Beta, which experiments with new technology in broadcasting, launched a streaming service in 2007, which was the basis for the streaming offering they are still providing today.

It's worth mentioning that NRK and Norway has taken inspiration from BBC since the dawn of television, including the licensing system (which has just been replaced by a fixed tax).
Which company? I'm interested in these sensors.
Problem is not that BBC is biased, but doing horrible job and divides society.

During brexit referendum it would be very easy to debunk exiter's arguments (£350 million a week for the NHS etc). BBC instead called people racist, supremacist and priviliged. People voted for brexit just to spite BBC.
Why reinvent the wheel?

Signal does the job, doesn't store data, not even metadata, and can be used immediately.
> For end-users, this means that the sites you’re visiting have the latest encryption and security standards to keep your data private.

No, it means the certificate was renewed recently.

I wish the UK would just scrap it as an independent license, and just include it as part of the government budget.

Like Norway did last year. Now they have it as part of your income tax. [1] This will save a lot of expenses in informing, collecting, organising, prosecuting etc.

I know that means everyone pays even though you don't own a TV, but that is fine by me. You pay taxes if you don't use every road, hospital, school, opera house as well.

(Note, their license fee was about £300 per year last year.)

Scrapping the BBC license fee and not fund it the same via a budget, but instead, a subscription-only will be awful. It will then join the other commercial channels which is 99% reality TV and gameshows.

I think it's too easy to be sucked in by the promise of distributed X or eventually consistent Y.

In the past I managed migration of a few services away from Hazelcast as the team started peeling away the nice abstractions they'd become used to so they could handle things they hoped it would protect them from. All of a sudden a distributed lock isn't a lock if your cluster splits.

In the end almost everything ended up back in Postgres. Resistance was surprising - there was a lot of opposition to simple things due to a fear that the database would be harmed by being used to hold a few row locks, for example.

I can see why people overlook the obvious when the complicated solutions seem more sophisticated, which is easy to mistake for "better".

Well when Amazon takes steps to reduce fraud people scream to high hell about how unfair it is to the small business trying to sell product. Take the case of Apple and Amazon working a deal where Apple products can only be sold by Apple or whom Apple authorizes.

I know the headache of trying to find a Silpat cooking mat, the number of look alike fakes is astounding and worse they use the name brand when they clearly are not that manufacturer.

So the only recourse is to have a setup similar to the Amazon and Apple deal. Anyone wishing to sell a branded product must provide proof to Amazon which includes the manufacturer backing the claim that they are authorized to sell that product. Not line, by product.

I don't know that cool new tech is the way value is created. Airbnb's first 'tech' was an Excel spreadsheet. Observe, on the one hand, the person recently open-sourcing the e-commerce platform they built after their startup folded, and on the other, the person recently asking what's changed in tech since 2017, only to hear "not that much":

Value comes from solving real problems that real people have. The good ideas aren't incubated in front of a screen, they start with people, and conversations, and a whimsical approach to what the future can be.
So in a way, the best thing you could do for yourself is to make a concerted effort to spend time NOT developing.

Your A and B are true, but not your C. The FOMO is eating you up, but your belief in it doesn't make it real.

I don't know that it's really about forgetting the outcome...the outcome DOES matter, but not as it's measured in money made/feedback on PH or whatever external validation.

If you do one thing that solves a problem for you, even if it's you alone, there's a quiet joy in that. And the more attuned you are to thins kind of joy, the more attuned you become to where you and software connect, and all the other stuff falls by the wayside.
