>Financial and real-world decimal calculations is the norm.

A significant amount of financial calculation is not in the nature of 'sum this column of numbers'. Most computation in e.g. derivative pricing has a lot more to do with scientific computing than it does with accountancy.
16 million is way too few because of collisions and the birthday paradox. Even with a tiny corporate network, you are likely to connect to other companies’ networks, and, with private addresses, no one coordinates allocations. Collisions are quite likely.

Also, the major players probably have more than 16 million devices, especially if you could VMs.

Pretty sure a callback vs synchronous style of coding is a little more than syntactic sugar.

It's a complete shift in application design...

The problem, in the end, is the other side of that inelastic demand.

Everyone needs to live somewhere. Landlords only profit if their properties are occupied, but they can simply decide to all increase their rent by $1000 a month, knowing that eventually, the only choice for some people will be to pay it or be homeless.

I have no idea if it would actually work this way in practice.
Same here I understood it as sending insta reeling from the decision.
The existence of hardware Apple emulators is quite interesting. Especially since they were for TRS-80 and Commodore 64.

WSL is the closest thing I can think of today that gives us that kind of interplay "out of the box," and that only came after decades of proprietary animosity.
It is a bit odd from my perspective because I have not seen/heard of "Axios" until this "Trump Interview" thing happened. So I understand the OP's bafflement at it's prominence all of a sudden. Even the fact that they got an interview with the US president seems out of place to me.
It is an interesting definition of competition if you can stifle it by allowing competitors who offer very similar or identical products.

When I was a kid that was competition.
Clearly they would if there's money to be made, as we've seen in China.
Copying snapchat to make stories. TikTok to make Reels. And fb originally bought Instagram. Can the big players just copy or buy every competitor at some point and remain on top?
Anecdata for sure, but my younger aged family members (and their general age group) on TikTok are all on Instagram.
Many financial institutions are required by regulation to enforce a minimum contiguous two week period without accessing internal systems. Even if the regulations don't require it, it's not necessarily a bad idea.

If your systems are so fragile that they can't cope with a two week absence, that's a problem. And the point of the regs is to flush out people who are trying to cover up problems -- two weeks may well be long enough for someone else to notice something they wouldn't normally notice because the person who is away would normally "deal with it".
Not necessarily. for the [flagged] to appear it requires a certain threshold of flags, but the ranking is affected before that.
Yep, super annoying for me as well. I paid $60 which I feel is quite a lot for a password manager. When I built my new computer the other weekend I found everything on 1Password's site was subscription-walled, I finally found a download via a hidden Google backlink. But, of course, since I don't have a subscription it's now in read-only mode... feels really scummy of them.
I doubt there's any component in a PC getting remotely close to the ignition point of oil (which for canola is 424°C). Plus, it's going to be a minimal amount of oil.

I'm more worried that the oil won't get to a high enough temperature and thus won't polymerize, so it'll flow out and ruin some other component, or go rancid, or something. Thermal paste won't move on you. Oil will.
Touch screens are horrible for frequently used controls in cars.

Any car you are in is traveling with kinetic energy, so it is likely to bounce and move around over the road surface. Without a physical button to rest your finger on it's nearly impossible to get something on the first "touch" unless you are standing still.

Yes it looks cool, and yes it's fun to play with on a red light, but using any of these touchscreens even at 50 mph is nearly impossible.

Made much worse if it's a sports car and has a bit of a stiffer suspension.

One step forward, two steps backwards.
Should've called it "Moments" or "Memes."

> Every large server-rendered app I've worked on ends up devolving to a mess ... that is a big pain to work on.

I can honestly say the same about every large SPA style app I've worked on and I've worked on several. Rewrites are the norm in the JavaScript arena because code devolves into a complicated mess then people look at it and say "It's just a JS app–there's no reason it should be this complicated!" Then they rewrite it with the latest framework magic, rinse, and repeat.

EDIT: I have to go further and (respectfully) say this comment I'm replying to is a load of BS. It's responding to a big pile of data saying that pageload speeds are not faster today with 'well that's not my experience.'

The other aspect of this comment that sets me off is what I'll call the "you don't have to use JSX to use React" type rebuttal. With this type of rebuttal, you respond to complaints about the way 99% of people use JavaScript by claiming that it's not strictly necessary to do it that way, despite the fact that "that way" is how everyone does use JS as well as the way thought-leaders & framework authors suggest you use it. It's responding to real-world conditions in workplaces with a hypothetical-world where JS is used differently than it is today.

This type of argument always shifts the blame on to individual developers for "using JS wrong." When 90+% of people are "using the tool wrong" there is a problem with the tool and it's not reasonable to shift the blame to every user who's trying to follow the latest "best practices."

I wish we could acknowledge the facts of the JS ecosystem (like those presented in this article) rather than deflect with "not all JavaScript apps..." when mostly what you're talking about is demos & contrived speedtests, not real-world applications.

If 'ifs' and 'ands' were pots and pans, we'd have no need for a tinker.

They weren't a Snapchat killer but they immediately cut off future growth and stalled it out for a solid 2-3 years.

You don't have to kill the competition in social to win, you just need to stop their growth. They can retain some percentage of users but if the growth is stalled out and you are dominate them in 5:1 marketshare it's as good as dead.
It's your responsibility to buy a car you can operate without causing an accident. If you can't use its wiper interface without losing control, don't buy it.

The same as when people buy power cars which are difficult to drive without training and then oversteer and crash.
This is not even remotely true, I once worked at a team in a company which aggresively run user segregation and send marketing emails based on it, then they collect click data to curate more effective emails

It is arguably more bad faith to assume the criticism is legitimate.

Its at best intellectually dishonest and at worst condescending/arrogant to assume people can't not form racist views because they can't figure out the context when someone uses the name of a color.

Am I supposed to mince words with my doctor when I am trying to describe the appearance of my severe frost bite? I don't think any of my black friends would take offense to me saying "my toes are black, this isn't good."
The regular Work visa is hard to get yes if you are older, but Blue Card does not have any age requirements or savings, as far as I know (otherwise, I would not be able to get it in the first place).

I assume most of the readers here would be able to get a job that is above Blue Card minimum salary, since the median pay for software developers here are above the requirement.
I feel similarly. I started subscribing to the monthly magazine "Le Monde Diplomatique" - they focus on in-depth analyses and not the daily or even weekly events.
When I was younger (read 20 years ago), I did crazy things like that, not over that long distance, but moving live servers in different racks.

Now that I am older, I don't think I would do it anymore, too much stress for a small reward. Also today, most of the time, I am able to "talk out" customers of crazy requirements, while I would just have said "OK let's do it" in my younger years.

On the Model 3 (the car in this article), the wiper controls are on a 'card' that you can swipe across to bring up. When the wipers are activated, either automatically or manually by the stalk on the steering wheel, that also brings that 'card' to the front.
America is way behind the curve here. It's typical for a South Korean restaurant to have a button on the table. The staff will only come over if you press the button.

It's a much more pleasant experience overall.
Not just Tesla. Every car manufacturer. So far it's only Mazda IIRC who said they are getting rid of touch controls. Meanwhile Mercedes Benz proudly advertisers this crap: https://youtu.be/SuFE5x6fPqw
That's an interesting approach. It incentivizes users to have a backup plan while also providing an escape hatch if things go wrong. The only issue is, like you alluded to, this could price out a large portion of the world's developer population. Perhaps the price could be determined by where you are in the world, although this may not cover US support costs. That and users could attempt to game the system by faking their location. Regardless, it's an interesting approach I hadn't considered before - I like it.
So the idea isn't to literally hop? They ultimately want to land it the same way the F9 rockets land now, and this is just a test?
I agree with your two sentences, but would add that a driver has a more fundamental must which is to correctly prioritize their attention so as to avoid causing a single-vehicle crash via distraction. Whether it's a two-knob radio, a touchscreen wiper control, swatting at a bee, or handling a sneeze is largely irrelevant as to where the most immediate responsibility for the crash lies, IMO.
Mutants Against Bugs: Implementing mutation testing in a niche language
For sure we see a lot of synergy with the CI systems. One of our alpha customers is using CircleCI (no surprise there). They have an issue where devs deploy services on top of each other in staging and accidentally take it down for their internal users. So Speedscale lets them detect their new build is not a good candidate to deploy to staging.

I think one of the things I have started to realize is how rarely people in Rails-land tend to reach for more established patterns that are generally thought to be important to writing good object oriented code.

There seems to be a real adversity among many to go ahead and create new classes as needed especially when that new class isn't obviously a model, view or a controller.

I just went over a short YouTube series DHH (creator of Rails) did where he walked through the production code behind Basecamp and I was struck by how different it looked to almost any other Rails app I recalled looking at previously.

But it seemed like there was not a whole lot that they were doing that would seem in any way out of place from a SOLID OO perspective. It's a very interesting set of videos to take a look at what a modern Rails app with a decent amount of complexity looks like as intended by the team who wrote the framework.

Design Systems in TailwindCSS? Material, Fluent etc.
What if you get components made up with tailwindcss from different design systems like Material Design, Fluent and Carbon.

In this, way we don't have to learn new classes or read docs, to get a design system's code we love.

For Example: https://demos.creative-tim.com/material-kit/index.html made with TailwindCSS. *(like TailwindUi)

did they hurt their competitors by copycatting stuff? It seems like tiktok has a different user base that does not overlap with the way ppl use instagram.
Never used Tiktok, or Instagram, and Facebook just now seems to be nothing more than a feed of irrelevant ads to, and any friends' or family posts are relegated to the little bell icon.

I barely look at it more than once every few days now as it has lost much of its utility.

Most of my friends and family are on other social networks and sites (twitter, strava, discord) now with fewer, or no ads, or even just whatsapp groups on the phone.

I wonder if the conversions went up included a disproportionate amount of mobile users.

The chat bubbles are far too big on mobile devices.

I go out of my way to instantly close them and it does not delight me in the slightest to have to deal with them.

Having a chat button to press that is unobtrusive is a far better layout.
This flips the typical narrative of "Chinese companies copy our products and their government lets them" on its head. I understand why this is a valid business move, but I think that the sense of moral superiority over China that is so pervasive in conversations with Americans is even less credible now.

The case is in Germany though!

However it could indeed lead to mandatory safety standards requiring physical controls.
If the car was approved for sale in Germany, then it was approved for sale with the control system as delivered. If the courts have an issue with the regulatory bodies that approved having a Tesla on the road, they should go talk to them.
It doesn't apply to China specifically. The end result is for the rest of the world to understand that operating in the US is as risky as operating in China...

The real lesson is that the teller of the tale sort of did initally -- fire the customer.

If the story is true, the client is a stereotypical know-it-all small business owner who gets by on bullying. You see them frequently in businesses that pay low-skill workers a small premium that is hard to replace. (ex: cleaning services, pool guys, mechanical contractors that do low-end maintenance work, etc)

As a contracted SME, taking a job like this is dumb. The chances of failure, where "failure" == the server going down is high, and the customer will just stiff you.
I've worked with H1 software engineers in the past, their skills ranged from highly capable to not very capable (same distribution i found among American software engineers), but one thing that stood out to me was how hard they worked for their average to below average wages due to the fact that they feared getting laid off and being sent back to their home countries. I knew a guy who was at the beck and call of our then manager almost 24/7, this definitely creates unhealthy expectations in the labor market in general.
I don't think the main reason car companies are shifting more and more functionality to touchscreens is because of the perception that they're "smart". I think it's because touchscreens are cheaper, especially in terms of development costs, since it's easier to iterate in software than hardware. I'm not super knowledgeable about the field though, so maybe someone who's worked at a car company can help explain.
LADR is probably the best linear algebra book around. It's a bit of a shame that the "marketing" mostly involves the fact that it does not use determinants.

The last edition also contains chapters on stuff like dual spaces and quotient spaces, which are important yet very often missing in other textbooks.

That being said, his reliance on C/R in about half the book could be a problem for people with CS background. Like, what if I want to compute determinants of linear maps which are over Z_2? There are also no chapters on number wrangling (like the gaussian elimination and friends), which is a big plus in my view but possibly a problem for others.
I personally like the name Reels, it implies a level curation needed in the process.
I’ve been developing a lot of serverless over the last 18 months. And oh boy, the logging tools for cloud based infrastructure are either a) to heavy or b) painfully tedious to dig through when all I want is to read console.logs.

So over time I built up this tool that I now call Twig, which I use a lot in the early stages of a project when things are moving fast. A few months ago a coworker asked if I could bundle it up for her and so here we are…

Would love to hear what you think.
I disagree. Mathematics is a tool to practice our hobbies .. see Feynman‘s biography.

Rot mathematics is where it goes wrong. Meta mathematics, abstract, detached from real life, as alot of the academy with its publish pr perish thinking ... that produces pain. Existential voids filled with an exercise that does not help many to move forward optimally.

saying weirdos hate logic is extremely dismissive to a lot of what I would call the human experience.

The same stuff can be taught with soul and purpose If we actually show children how they can apply mathematics to improve and enhance what they’re actually doing whether it is building castles in Lego, Or designing faster toy car, A better school project volcano, etc
I guess in order to see things you have to open your eyes to it.
Another data point. My sons group are all on both, but no one actively uses IG. TikTok is their app of choice. My son says IG is boring. I think Reels has a major uphill journey.
I think the point was more that allocations are fairly explicit.

There are a few places in C++ where allocation can happen pretty much invisibly. A copy constructor is an example of that. You might see a new allocation simply by calling a method.

With rust, you usually won't see an allocation unless it is explicitly called for. You can follow the call tree and very easily pick out when those allocations are happening.
Are users tired of filling feedback forms?
So we've started our business a bit more than a month ago and it's going(ish). subscriptions are coming in at a very slow rate, nothing to be able to live from but better than nothing i supose at this moment.

There is this one thing that's troubling us, how do you make users to give more feedback?

We've tried several things like:

- Sending newsletters with surveys attached
- direct outreach on our support channel (crisp)
- Twitter comments and direct messages
- Reddit messages
- Hotjar surveys
- ...

Most people give a "great", some give a 0 when i ask them to rate (without further explanation). I've optimized a lot of hotjar surveys to poll for more feedback when they give 0 or follow up messages to not just get "great". But it seems like almost nobody feels like filling it in, are users tired of giving feedback?

What are your thoughts? How can i increase this conversion rate to be able to iterate properly.
This is another example of why replacing tactile controls in cars is a bad idea.
I think the European courts still expect you to behave responsibly and not forgoe usage of your brains just because someone put a regulatory stamp somewhere.

This US-like transfer of responsibility to more and more overbearing regulators (and regulating corporations like Apple/Google/et. al.) has always seemed very harmful to me.
There is a reason, why India banned not only TikTok, but 58 other apps of Chinese companies, after at least 20 Indian soldiers were killed in a clash with Chinese forces this year. It's called national security.

Russia's Yandex, Mail.ru, and VKontakte have been banned in Ukraine since 2017 for the same reason[1]:

> Russia also continues to hack into individual cellphones, with Ukrainian Colonel Ivan Pavlenko saying that the Russians had gotten into his phone at least twice in 2018. He also confirmed that Russia has used its ability to tap into cellular networks to send SMS text messages to Ukranian troops.

> These are tactics that the Kremlin has also reportedly used against NATO countries, including the United States, and allows Russia's intelligence services to both scrape potentially useful personal information and possibly insert disinformation onto these devices. The texts can also be psychological warfare tools, with past reports that some were purely insulting or threatening. Using hacked personal information, those threats could include very distressing ones directed at family members or significant others.

I believe, that the Internet of the 2020s cannot be compared to the Internet of the 1980s. It has become a business platform, and any country has the right to ban a foreign company from operating in its territory.

Especially so, if that company is based in a foreign state that is not considered trustworthy. And trust is based on mutually shared values: which the US and China have almost none.

At least to the Communist Party of China this has been clear for decades.

The risk here, if I'm not mistaken, is far from being teens lip syncing, it's the ability for a foreign actor to control the algorithm of what Tik Tok users end up seeing in their feed days after days.

This could potentially be used to stir the political discourse of a country towards one outcome or create unrest by putting groups of citizen against each others, etc. All done by controlling what users see.
