I worked in this industry. 2 more common issues:

* Doing a latency-sensitive trade when you don't have good execution. It's easy to go wild in simulation and think you can flip in and out of positions. But if you're a retail trader (and in this context, by that I mean "not connected directly to the exchanges, at the minimum")

* Not taking into account the impact of your own trading on markets. This is obviously impossible to really simulate. Sometimes you can ignore it (if there's enough liquidity) but I've seen trades that looked great on paper and when trading at small-ish sizes, but then when you try to crank it up and do more volume, prices run away from you.

Obviously, there is money to be made in algo trading. It's big business and obviously not everyone is doing crazy latency sensitive stuff- there are quant trades that you could probably do with execution available to retail traders. And honestly I wouldn't be surprised if some retail traders manage it. But I will say that I think for an individual, it's not worth the effort even if you are ones of the ones who can consistently make a profit. Just buy sp500 ETFs and sit on them and do something else with your time.

From a marketing protective it may have made sense to revamp the website before launching 2.0 since you could've made a lot of better first impressions.

I hold Nokia stock for years and assumed they'd have been bought out by now. I don't know why they haven't and I had high hopes for some action on that front when the US kicked up the storm about Huawei and 5G infrastructure. But even after that Nokia couldn't benefit. There's something wrong with the company. Maybe it's too Finnish.
Not yet. I will do soon, but I have some things to wrap up first. When I have something to show I'll post it here.
Nokia had a number of problems back before Elop joined. Those were the cause for the actual demise. Elop did his own bad by going Windows Phone instead of Maemo but that's another story.

Nokia did a very good move in 2008 by acquiring Trolltech (Qt). And then they screwed it royally: instead of immediately started launching phones with Linux and Qtopia (which was mostly ready for mainstream market), Nokia kept launching Symbian phones.

They had this plan to use Qt as the migration platform from Symbian to Maemo. That was a good plan. Except they could have started a lot earlier: why were the Nokia N770, N800 and N810 only tablets and not phones, when what everybody was asking for were phones?

Because back then Nokia middle management would internally destroy any attempt to actually improve or replace Symbian with a serious alternative. Symbian ruled. That's why the first thing Elop did was to fire (outsource to Accenture) everybody working on Symbian. It was a blunt way of saying: "you no longer are Nokia, you will no longer decide what this company does".

Everybody was very excited about Maemo back then. While it was no iOS or Android, there were A TON of developers (and companies) looking into migrating their Symbian apps to Maemo with Qt, or even writing new applications.

And Stephen Elop decided to use Windows Phone instead of Maemo. This is what actually destroyed Nokia: Windows Phone 7.5 was released with no support for C++, which left Qt out, which meant you needed to rewrite your app from scratch. That was the single defining moment where 99.9% of app developers decided they would rather go Android or iOS, and Nokia was doomed from that moment on.

As for the comments regarding the little success of the Nokia N9 or Nokia N950, the reason was they were simply not launched in many countries. When they announced the countries where those phones would be available, it looked like a bad joke.

By the way, another very stupid decision by Nokia, which shows you the power of the Symbian people back then: the Nokia N900 was released in November 2009 with 256 MB RAM and 32 GB storage for 599 EUR. Back then, phones had 64-128 MB RAM (256 MB was rare) and 512MB-1GB storage. Do you know how expensive was 32 GB flash in 2009??? They could have sold this phone for 400 EUR with only 8 GB flash, which was still a lot in 2009, and it would have reached a lot more public.

Really, Elop made the fatal mistake of chosing Windows Phone instead of Maemo. But Nokia had inflicted a lot of damage on itself already. In fact, the only bad thing about Windows Phone was not allowing C++ (and therefore Qt), which rendered all existing apps useless. But Elop probably never knew about this.

Oh, and don't even get me started on another huge mistake: trying for many years to use Gtk instead of Qt. Nokia lost at least 2 years with that. Guys, Gtk was nowhere near Qt back then, and it's even more far apart today!

(I was very very close to Nokia, with many friends inside, in those years and was about to work for them when Elop announced Windows Phone would be the next big thing)
iMessage is not being attacked because it's not as sandboxed as other apps. It's being attacked because it's accessible with zero clicks.

For an attack like this you need to chain an iMessage exploit with an LPE, and the LPE can be launched from any other app.

On the other hand: Most articles are pretty fluffy and don't bring much to the table, and so are just an invitation to discuss the topic at hand in the comments at what is usually a far greater depth than the original story.

Long time fan of kivy checking in here. Important if you wanna be off internet grid. Portal to OpenGL as well. Kivy hugely underrated and better than QT imho. Made a 2D skateboarding game and tried to get it working with buildozer on android back in the day (2017) Cheers to the devs.
The lab I'm in has tried approaches with this.

It's effective, but the so-called "boundary cases" often have to be hand-chosen due to the difficulty of selecting them automatically: Early samples always have high loss and the decision boundary nearness is implicitly connected to the accuracy of the network at time of evaluation. In other words, the function we evaluate on forward pass itself is changing as a result of backprop, so the critical points and output of the function are also in flux.

You also lose an increasing portion of each batch to the "important" cases as you add more, so maintaining the size and contents of this pool is difficult - if you added every case, you'd have no new data.

So I think it's promising, but it needs more foundational work on deriving the impact of individual samples on the output. (If we ever get that breakthrough in explainability...)
Reminds me of Dijkstra's aphorism:

It's perfectly safe. Soy sauce and parmesan cheese has naturally occurning MSG. MSG is added in campbell and lipton soups, Doritos and Pringles chips, and dozens of menu items at McDonalds and KFC.

Ajinomoto is the powdered form that makes MSG easy. Traditionally umami is extracted through fermentation (as it is in soy sauce) or through konbu (seaweed) or fish (vietnamese fish sauce, katsuo dashi).

The only potential issue, as with any food, is with allergies. Growing up in Japan, there was a rumor that Ajinomoto may contribute to atopic dermatitis (atopy). Still doesn't appear to be any evidence of it [1].Of course, peanuts, milk, soy, wheat, fish, and eggs are the most common culprits, so it's not bad company to be in even if it were true.

The Primal Scream Line
This may be obvious to everyone else, but it wasn't until I adopted a dog that I realized how much "playing" is reinforcing skills needed for survival, like hunting and fighting. When dogs play with each other, they mostly wrestle or chase. It's hopefully in a non-violent context at the dog park, but it exercises the same muscles and reflexes that dogs would need for real fighting. It's been cool seeing my dog grow up and get better at skills like catching a ball in midair (chasing prey).

Even human play mimics skills needed for survival, we just need more complicated skills, like war strategy and creativity. Just think about sports, board games, and so on.
bold of you to assume they have QA.
He didn't say "insurance monopolies."

Presumably it could work the way auto insurance works, where you'd be required to carry insurance but you'd have your pick of who supplies it. (Unless I misunderstood and you're opposed to requiring insurance for anything.)

another one related to stock trading, but perhaps more interesting- build a simulator for a sport. both baseball and darts lend themselves to markov models, and are simple enough to simulate in some detail. with darts, you can get very close to as accurate as possible. baseball has more weird complications because of the rules. but its fun to do, and to compare to old games to see how well your model does.

This is all wrong, and ironic given your complaints elsewhere about misinformation on social media sites.

For example, moderators don't count for more than voters on HN. The site is moderated [1] but this is a sort of feedback mechanism to prevent the system from getting stuck in an uninteresting end-state (e.g. overwhelmed by the same few sensational stories over and over). The only thing we care about is keeping HN interesting for the community, and it's the community that decides what is interesting, not us.

The bit about users with 500+ karma is also wrong, but I doubt it makes sense to bother going further into explanations.

I think you've hit on the true issue.

The majority of people have only leared on a superficial level of of the intertwined racism of America's past - often times mostly the light touches they learned in elementary school. And what's taught in elementary school is intentionally simplified to something deemed appropriate for children. Some summary of slavery is bad, MLK, Rosa Parks, sit-ins...

Most people don't actually learn anything about American's history and ties with racism at an adult level. So instead people think they know the history of it, and as a result think (based on what they've learned) it's overblown.

Anyone I know who has actually taken time as an adult to read about American history and its relationship with racism, comes away with a very different view point.

It's so intertwined it's incredible.
Pedantic: I don't think it's really a strawman. It's conclusitory instead.
but which tech companies do devote enough care, resources and money to cybersecurity?

I always figured the industry never really rewarded those things over aspects (e.g. time to market).
I'd also recommend writing an emulator for real or fake (e.g. CHIP-8) hardware. It seems complicated but the core loop gets pretty simple. It ends up giving you a much better view of both assembly and pointer semantics (useful for better understanding C).
I read somewhere (on HN?) that Italians speak faster than Germans because their words contain less information, so in the end they still communicate the same amount of information per minute. Italians and Germans were used in the example because they were the two extremes.
Why do you use both every day?
I'm also talking about regular career choices (not academia) that only involve a three or four year undergraduate degree. Women self select out of technical pursuits (CS) and self select into more verbal or empathic areas (Law or Medicine, and an even more extreme example being liberal arts) even though such areas might entail even more study than CS. This self selection is magnified when women have more choice and freedom. Women in software is more common the more poor a country is.

I mean it's not only career choices where such gender differences manifest, we also see it in the choices that young children make. The burden of proof is on the camp that proposes that it's entirely sociological since the extant empirical evidence, along multiple independent lines, contradicts it.
Wow, these “virtual restaurants” is not what I envisioned at all.

In my head I expected each brand had their own kitchens, with their own staff, processes, etc specifically for making the brands menu. But really when you order, a random nearby restaurant makes the food, and I expect gets nearly none of the revenue. It seems a bit dishonest to the consumer.

Non-instant ramen is also essentially salt + oil + glutamate flavoring + noodles.

While I have very little doubt that xenophobia was a large factor in the hysteria over MSG in the United States, there's definitely no need for a "Maybe" here. Just look at the "pink goop" claims about McNuggets that range from two decades out of date to completely falsified - people are willing to believe all kinds of nonsense that fits their preconceived notions.

Very annoyed by the comment of no innovation since 1800. Basically computer is invented there, developed there and now sort of re-invented there.

Would you enjoy your favourite meal if it were the only thing you could eat for the rest of your life? If not, is it the food you enjoy or the variety, novelty and choice? After a strenuous workout would you prefer to sit down to a heavy meal or have a glass of water? The pleasure you derive from something is not an intrinsic property of that thing, the sense of pleasure comes from within your own mind. That is why pleasure is illusory, it is a state that exists only within your mind. The idea behind a practice like Buddhism is not to nullify everything, it is to draw the attention to the fact that all we know of the world is an illusion produced by our senses, we can never truly know the world outside of our consciousness since no matter how closely we examine it we are really just examining its representation within our own mind. It is meaningless in that all of these sense perceptions are essentially the same, the meaning we assign to them is once again something that originates from within us. This doesn't negate the external world, it is just a different way of viewing it and a useful one because it puts into perspective many of the frivolities and aimless paths we trace through it. You don't have to be an ascetic but you don't have to let the world subsume you completely either.

It's because the German language is highly compound. Take any descriptive phrase, remove the spaces, and you have a new word.

In English, it'd be the equivalent of taking "make worse by improving" and turning it into "makeworsebyimproving".

When I was learning German, we were taught the language has far fewer core nouns than English (4000 vs 20,000 is stuck in my head, but this is going back years), but then they bash them together to get the rest of the concepts.

They went that way for a reason, though.

Very comprehensive answer, thank you! I'm glad to hear that Kivy has larger aspirations than simply being a mobile focused cross-platform solution, and that it's got enough of a community to sustain its efforts. Cool also that it's able to leverage Python tools that the native mobile apps aren't able to hook into. It sounds like Kivy does have a small community of avid Pythonistas.
I would add "build a toy regex engine" to the list.

A couple of years ago I implemented a toy regex engine from scratch (building NFAs then turning them into DFAs). I thought it was an enlightening experience because it showed me that the core principles behind regular languages are fairly simple, although you could spend years optimizing and improving your implementation. How do you deal with unicode? How do you modify your implementation to know how many characters you can skip if you don't have a match in order to avoid testing every single position in a file?

It demystified the concept of a regex engine for me while at the same time making me realize how impressive the advanced, ultra optimized engines we use and take for granted are.
