A perceptive assessment. You've got Ikea, which is generally quite tasteful, and then you have the likes of Target furniture, which is also tasteful yet somehow makes even the lowest-tier Ikea pieces seem rock-solid in comparison. You can step up to Art Van and get agonizingly milquetoast design for about 1.5x Ikea prices, or fiddly, baroque Arhaus for 2x.

Then you jump up to the likes of Restoration Hardware, in that 4-5x Ikea range, with the real vintage aesthetics Arhaus is hamfistedly aping, and after that, the ironically-named Design Within Reach which matches Ikea's minimalism with maximum durability at what seems like 10x Ikea prices.

I would say the one thing you've missed is Crate & Barrel, which is in maybe a 2-3x Ikea range and tends to have very tasteful design along with across-the-board durability.
There's been a lot of comments about Chinese HSR here costs, figure I can cover a few things:

1. Their labor cost per mile is a tiny fraction and their work safety standards are far different.

2. Iirc (not 100% sure) the cost per mile is lower as well because they are not taking into account property acquisition costs.

3. The actual equipment they use comes from companies either not selling at a profit or at a steep discount.

I still don't have an accurate enough picture here, but it doesn't seem apples to apples at least.
> Something along these lines (although by far not that bad) happened to me when I traveled to NYC for vacation of New Years Eve 2016/2017(this was before Trump took office).

Incidents like this have probably happened hundreds of thousands of times throughout history, at customs checkpoints for many different countries. But now that Donald Trump is the president of the United States, a certain percentage of the ones that pertain to entry into the US will become international news stories that will routinely make it to the front page of HN.

It might seem silly to you but I think that the import controls to protect domestic agriculture make sense and preventing unintentional/incidental imports like this one is an important part of CBP's job.

They should spend more time on this and less time on rejecting visitors to the US.

> Any reason why you wouldn't just put 3 GPUs in a regular chassis and be done for a quarter of the price?

Not a *coiner but I can guessL

With most motherboards even 3 GPUs will require you to have the cards right up next to each other. This is not great for cooling, which is important when you have the GPUs cranking away at full bore.

Also you can only get 4 GPUs at max in to a normal size PC case. With these you can have a single host PC running 16+ GPUs.

I was going by wikipedia "He emigrated to France with his family in 1956 due to the rise of antisemitism in Egypt.", but if we click through to the source for that statement we get

This is a problem. In epub, you can use MathML, but support on reading systems is spotty. You could embed something like MathJax, but that would also depend on there being scripting support (not all systems have it). On the Kindle, there is none--no Latex, no MathML, no scripting, nothing for math support at all. Your only choice is graphics. SVG or high-res PNG works best. Though on a Kindle, there's no "S" in the SVG (i.e, the Kindle can't actually scale SVG). Occasionally we do a math-heavy econ book here, and it is always a compromise.
Tesla went public on 29 June 2010 [1]. Since then, it has traded 1,677 days. It's average (median) movement, from open to close, is -0.01% (-0.09%). There have been 50 days when Tesla stock fell at least 5% and 53 days where Tesla stock rose at least 5%. So about 6% of the time, historically, it's "tanked" or "boomed" by a similar amount. (By coïncidence, the average >=5% movement is +7.452% while the average <=5% movement is -7.458%.)

Note: this is not a traditional presentation of volatility. Its point is to narrate, not power trades.

---

So what should you be looking at? One, there is heavy bearish sentiment around Tesla, representing about 30% of its float [2]. Short interest ratio "is the ratio of tradable shares being shorted to shares in the market" [3].

Two, Musk's reality-distortion field just faltered. None of Musk's companies have ever been realistic about timelines. But having a Goldman Sachs analyst publicly counter Tesla just a week after "Musk said the firm’s new vehicle is on schedule to arrive in July" is a new level of assertiveness.

This is salient given Tesla's short-term need to raise boatloads of money. I'd keep an eye on Musk positioning back-ups to Wall Street through political channels, e.g. low-cost 'infrastructure' or 'domestic manufacturing' financing and/or government contracts, while he repairs his warp field.

Give small people a little bit of power and the results are very predictable.

Real lives > paper, that's the bit that people in uniform the world over seem to instantly forget the moment they put on their work clothes in the morning.

I've seen so many examples of this in my life by now that it hardly surprises me any more but I still absolutely boil at it every time I see another instance.
This isn't a competition. While I appreciate that you were only trying to be helpful, in reality proposing false theories doesn't add anything of value to a discussion, especially when the issue can be settled with a basic web search.
As someone that also implemented A/B booting for the Pi: I wonder how you roll back fully automated? I read a bit of the code but wasn't able to find that. Or is that already handled by u-boot?

In my case, the first thing I do once an unverified version boots is to switch back to the other partition (so the known good version is active during the next boot), then run a detached reboot process that forces a reboot in 5 minutes. Once the system is up and it verified that everything is ok, it commits the next version (by switching back to the partition that booted and marking it as confirmed) so it is now active by default. Finally it kills the still running 'reboot' process.

As far as I understand your update process: You download a complete new version for every update and are able to stream that directly to the new partition? Is there any way to do delta updates? In my experience, most of the disk content is unchanged, unless you do major updates. In my case I download the new version using zsync, verify the downloaded/updated `install.zip` (which is kept on the volatile data partition), then extract that to the new partition. I make sure that `install.zip` is created in a way that it is rsyncable, so updates are pretty small that way. Of course you lose the streaming feature, unless you modify zsync somehow to support that.
Right. The only thing C had going for it was that it was the fastest non-assembly language.

I'm biased, I want all C development halted and moved over to Rust. If C is no longer the fastest, for some definition of that, then no one should be defending it at this point.

Honestly, I want the LLVM optimized C version specifically so that this last argument for C in any context will be taken off the table. I'm sure there are some people saying, "but it's not using the same compiler backend and optimizer...", I want this to counter that.

Rust all the things.
Routinely blocking the air inlets and outlets on a laptop increases the probability that electronic components will fail over time, though most modern laptops have multiple forms over overheat protection and will throttle CPU speed or even shut down if they get too hot. I should note that all the airflow in a Macbook Pro is through the sides and rear, not the bottom, so setting it on a soft surface would not typically block the vents.

The temperatures that start to increase failure rates for electronic components are far lower than those that trigger thermal runaway in Li-ion batteries. The least thermally stable Li-ion batteries, those with cobalt-based cathodes, are at risk of thermal runaway over 150C. I've never heard of poor cooling being the root cause of a laptop battery fire.
If you're going to be worried about everything that has a small chance of failing and injuring you, I'm sorry to say you're currently living in a minefield. But statistically you'd be more likely to break your toe on the coffee table than your laptop exploding and burning down your house.
Remnants of working with energy consumption and smart meter data - our examples are still a bit focused on that. On the other hand, the current version is able to handle distinct/heterogeneous intervals, although it clearly does not perform as well. We try (maybe too) hard to mangle the incoming data into something as _standard_ as possible for our models, and sometimes those transforms are not kind to sparse data.

Defective batteries aren't that new to Apple, I remember having to exchange the battery from my white pre-unibody MacBook twice because it was swollen by over a centimeter. There was a recall even IIRC. Of course, back then you could swap it out yourself.
I had the exact opposite experience, I went in to a store with a MacBook Pro (2013) which had morphed by a good 1-2cm's due to the battery expanding over the course of the previous hour. They refused to take it and insisted I book a genius appointment for the following week.

After much insisting (30-40minutes) they finally agreed to take the battery and keep it in their safe for a week, until the first available genius appointment was available. There they said it was out of warranty as its a disposable part and therefore not covered by the AppleCare+ plan I had at the time. Genuinely it was the worst experience I've had in an apple store to date.
I think this should be higher in this stack of random things because that's just one of those things that makes someone seem naive. Ok, you are junior person in a company- can you explain how your paycheck is funded? Can you see why what you are working right now directly benefits your business? Why is this area of the system more critical than that area of the system? What is the customer perspective on whether this works or not and will it affect the money?

Much like the other mention of communication this is just one of those things you learn on the job and outside of school/solo work. This knowledge also helps guide your decision making/architecture work with dealing with a system over time as well as general decision making/prioritization.

Is this somehow connected to facebook Prophet? How do you compare?
There isn't enough information in the article to determine the cause of the fire. He does say he was sitting in bed browsing the Internet, so it's possible he had the laptop resting on some blankets, which blocked the vents and caused the laptop to overheat and shut down.

I haven't heard of MacBooks spontaneously exploding under normal conditions.
It's especially ironic because one of the other posters mentioned about how he'll only believe it (your claim that there is a cultural purge) if it actually happens to you.
An earnest question I've heard from people trying to switch is: what's a good benchmark for testing where you stand in terms of coding skills? How do you calibrate and measure your production-quality coding skills in Scala, C, etc. when you have spent all your life in academia?

I feel Kaggle is sufficient for the exploratory part of data science. But Kaggle's relevance to testing and honing "production quality" code-writing skills is sometimes minimal.

In the larger context of programming and software engineering, scientific programming is fairly easy to code-up (though they are harder to conceptualize and understand mathematically). The coding part of non-CS/non-CE/non-some-parts-of-EE academia is pretty much mostly scientific programming. Yet, production quality code is seldom just scientific programming.

1) Be helpful. Colleague beating her forehead against her desk debugging something? Go help. Account manager running into a bug? Go help. Sales team encountering pushback from a potential customer? Go help. You'll learn a ton.

2) Learn why you're building something. Not just the technical 'why', but also the business 'why'. Yes, you should understand why you're using RabbitMQ over Redis. You should also try to understand the business case that you're solving – in as much depth as you can get. The stronger you align with what your business needs, the more valuable you become, and the harder problems you will be solving, an the more you'll have the opportunity to learn.

At the time I was choosing between these kinds of services, Dropbox and its competitors were all pretty comparable. I have great respect for the Python community and it's values, so when I learned that Guido was working there and that they were giving him time to work on Python, I thought it indicated a positive company culture. Why not go with Dropbox, all else being equal. Then they pulled this kind of BS repeatedly and appointed Rice to the board. I guess lesson learned about thinking good people will work at places that align with their values.
TSLA is up over a 5 year period, a 1 year period, and 25% in the last 3 months alone. As far as I can tell the only people who learned a hard lesson were those who bought in the last week or so. I believe the lesson they learned is: past performance does not guarantee future results.

Interesting. I recently published a paperback in a different space (color, lots of figures), and made completely different choices. I can't write anything nearly as long or specific as your blog post here, but in brief:

* I used XeTeX plus my editor of choice.

* I sent it to a few friends, listened to what they said, and read and re-read until my eyes bled.

* I avoided Amazon like the plague, instead using a small print-on-demand shop with reasonable prices.

* I sold via pre-sales, my personal website, and consignment at small bookstores.
No, not if it's weakly interacting.

Matter forms big balls because it collides with other matter and turns kinetic energy into heat. If dark matter is weakly interacting, it won't collide, so after falling into a star it will just shoot right back out the other side. It might form a stable orbit, but it also might just fly away and fall through some other gravity well.

You can probably expect some bulk gravitational effects (e.g. Dark matter might tend to cluster along large matter distributions like galaxies), but in general it wouldn't be amenable to staying in one place.

Let me give you an example, from visual perception.

The "Feature Integration Theory" suggests that low-level image features are processed in parallel: you extract information about the color, orientation, and movement in parallel across the entire visual field. However, these representations are separate, and a second, serial process is needed to combine information across the two areas.

This makes a specific, testable predictions. Suppose you're searching for a red triangle. If this shape is embedded in a sea of green triangles, your reaction time shouldn't vary as a function of the green triangles. The same thing should happen if the red triangle is surrounded by red circles--reaction times should be relatively constant regardless of the number of red circles. However, if you need to find a red triangle embedded in a mix of red circles and green triangles, you should a) be slower and b) your reaction time should be a function of the total number of shapes.

I'd argue that this theory is empirical (run the experiment, record reaction times) and about as falsifiable as it gets (it's easy to test the difference in RT. vs. item # slopes).

I'd also argue that this is a computational theory describing how visual search works, without worrying about the underlying implementation of that process. Clearly, it would be interesting to know that too, but it's certainly not necessary. David Marr proposed that cognitive processes could be studied on three levels: computational (what's the problem), algorithmic (what's a way to solve the problem), and implementation (what do the neurons do to run that algorithm), and each level was largely independent of the ones below.
I work in related areas of math but don't know anything about the applied side of this stuff. The general rule of thumb though is that whatever algorithm the mathematicians are proving correct is chosen so that it is easy to analyze and isn't going to have the best convergence properties for actual use. After this result, though, expect others to tackle questions like faster converging algorithms, stability, etc. There are exceptions though: Newton's method was both ridiculously fast and easy to work with mathematically and is still used in both applied and pure contexts today.
So each core has its own JS engine, or when you iterate across the DOM with a selector you have to query across all the nodes? This doesn't sound great.

(The "pile of cores with scratchpads" exists e.g. Tilera and Netronome, and they're a right pain to program for)
> you cannot pick this up in any meaningful way in a "few months" of after hours/weekend study

You can't pick up coding like this either. See Peter Norvig's famous "Teach yourself programming in 10 years" article. The delta in the wisdom you obtain, between a few side projects over months and battle hardened experience with real products and code bases over years, is immense.
Oh I see. That's cool! I do want to check it out but will probably wait for its release.

And I wait with bated breath.
I often reflect that if Elon Musk died (god forbid) the shares of Tesla would drop to a fifth or a tenth of their current value in the space of a few hours. It's incredible how much a single person can make the difference.
I can't imagine that anyone would be so foolish as to do that today, even if they had been so inclined years ago.
Once people realize that the self-driving dream won't be taking place anytime in the foreseeable future, I'd expect another big drop.
