Nitpicks: "A great deal of quality is lost as those huge files are squished to the CD format, before being further squished into MP3s on your iPod." Not true, AAC files at high bitrates are proven to be indistinguishable from the original. http://xiph.org/~xiphmont/demo/neil-young.html

"Every part of the signal chain—from earbuds to digital/audio converters—is improving and getting cheaper." Like other technologies, digital audio had rapid improvements in the first 10 years but has mostly leveled off as we have reached the limits of physics, signals and sampling. Good audio equipment is still expensive and power hungry in every part of the chain.

Technology won't save what are fundamentally psychological issues. We respond emotionally to louder signals. We like songs that sound similar but not identical to things we've heard before. We listen to things that our friends like. All of this points to why top 40 songs sound the same, but "all records" is pretty broad. There has never been a better time to create something new in music, and yet we lean heavily on what has worked before -- in songwriting, in arrangement, in production -- so that others will like and identify with the creative output.
Most of these "brogrammer" "frats guy" types that are loathed on HN tend to be a very particular type of person. They were uncool in high school, joined a low tier frat in college and then tied their entire self esteem to their club membership. They remain socially inept after college and therefore cling to their juvenille antics because that's all they know. [0]

In general, the people in the top tier fraternities tend to have extraordinary social skills and meld seemlessly with society after college. You probably wouldn't be able to spot one. As of now, these individuals are very much _not_ in software engineering.

Unfortunately, the top 3 or 5 large fraternities on campus take all the kids with social skills, and the bids trickle down from there. What you're left with is 15 or so fraternities that function as a factory for douchebags with weird personalities. These are the "loser frat guy creeps" that members other fraternities make fun of. Most outsiders are unaware of the social hierarchy within the Greek system and understandy lump everyone together.

If someone is still acting like a "bro" or "frat guy" after college then that's a red flag that they were the social inept guy in their fraternity or in a low tier fraternity.

A while back somebody commented that this very effect was a strength of TDD. It's easy to gain mental "momentum."

I'm not a strong TDD guy, but when I'm feeling a bit slouchy (or even overwhelmed) I'll often start with unit tests to get the ball rolling.
That depends heavily on with CPU and memory subsystem combination you're running it on. You need to know how far to prefetch and how to order your data in memory.
The problem with TeX is that it gets most of its current power from the large library of packages written on top of it (or on top of other packages, e.g. LaTeX). People expect those to keep running on any new implementation of TeX. Which means that you need to be almost 100% compatible; you cannot really mess with the TeX language in any way. So the best you could hope for is a clean implementation (or whatever we perceive as clean these days) of a processor of an ugly (again by today's perception) typesetting language. It's not clear that that is worth the quite substantial effort.

You can of course aim for a new typesetting language and just take the typesetting algorithms from TeX, but then it's a completely different product, incompatible with existing TeX packages.

> There's also no reason to presuppose that personal transportation SHOULD provide a livelihood. The goal of companies like Uber/Lyft is to take advantage of the currently wasted extra carrying capacity in personal vehicles. There's no reason to expect a priori that the value of extra capacity is enough to provide an income.

I don't buy it. Uber flies the flag of "the sharing economy" but their requirements for the car and the drivers make it look way more like a professional car service than an opportunity to share rides if you have a car.
I think that's time square. So the colors are real, from all the big screens with ads that stay lit at night.

Bernie Madoff had the same mentality. You get away with a little more each day until it's all you are. Sadly this type of story gives ammunition to those who decry science "if this guy can lie, maybe everyone lies."
You are right, but just that as a society we should stay vigilant in detecting and stopping companies that make profits using ways that are detrimental to society, the same should apply to politicians and security forces. There are checks and balances for that in a modern society, but they can't be watertight. One can only hope that society will feel the "pinch" (as you called it) early enough.
Thoughts about Rust from D programmer
I was on a grand road trip[1] and spent a couple of weeks in Whitehorse and met some really awesome people. We went White Water Canoeing, hiking, camping, etc. The wilderness and opportunities for adventure had me captivated, and I knew I'd have to come back. When I was in Argentina, I touched base with my friends up here and they helped me get a job with the local Telco, Northwestel.

It's extremely common to meet people here that say "I came for one summer...20 years ago" because it's so beautiful and the massive array of outdoor activities make it very hard to leave.

Decrease and Increase
I worked in Baltimore at the end of the 1980s, not far from Penn Station. The Monday Sun usually had a handful of murders to report from the weekend, and there was a shooting (not fatal) across the street from our office one day. The reputation for violence may be out of date now, but it was well earned.

Baltimore's disciplined voting habits have given it disproportionate power in the state government. The late William Donald Schaefer appeared to regard Maryland as a life support system for Baltimore, not just when he was mayor but when he was governor. I doubt it will do as well under Hogan who is a) Republican, and b) from Prince Georges County as it did under O'Malley.

But yes, there are perfectly fine parts of Baltimore.

I have no idea whether or not anything will ever happen with it, but I got a Curta teardown poster (shows all of the parts to scale) recently, with the aim of modeling each component. I'd really like to get everything machined, so I can have my very own.

I don't know if it'll ever get to that point, but it's one of my goals.

Edit: I should note, though, that it's unlikely to cost less than $1k per unit. This is more a labor of love and to get more of them out there, than an attempt to make them economical.
Not sure how different it really is.

I have to admit, as someone who is into quads (and embedded software) my first thought was that it would be cheaper to buy a $35-60 CC3D or knock-off dedicated APM module and then just add a Raspberry Pi to the quad as a separate unit. Having the two communicate is a bit more complicated but totally doable via serial if you're willing to hack on APM or OpenPilot code and a lot of the use-cases people are bandying about don't actually need the two units to communicate anyway.
How do you decide to put as sharding-key? Something like 'user_id'. What if a user becomes too big? Something like id=uuid. Then you lose the semi-free user_id index.

I believe the holy-grail of sharding is range-based (bigtable, hbase, hypertable etc).

Has anyone looked at the effects not on particles, but on changes to reactivity in the presence of magnetic fields? You don't need to rip apart molecules to kill us. Make certain reactions a little more or less likely to occur and we stop functioning.

I have seen some discussion of how heavy water could be lethal if it were to replace all of a body's water based on its very slight differences in reactivity.
The regulations actually don't require it. Under FAA rules for general aviation ("Part 91"), you need oxygen between 12,500 and 14,000 feet if you remain there for more than 30 minutes, and it's only once you climb above 14,000 feet that the pilot unequivocally has to have it. You need to get to 15,000 feet before the passengers have to have oxygen provided.

"White" light sources are generally not really white. For example compared to sunlight ordinary light bulbs are a bit orange and fluorescent tubes have a green hue. Our brain mostly ignores these differences, but a camera sensor does not. The author might have turned up the saturation on these images though, I don't know how strong the difference is supposed to look.

There is absolutely no need to use different languages and technologies within a microservices architecture if it is not necessary for your business. But to simply dismiss the business perspective from your perspective seems a little naive.

Some reasons why decoupling your architecture can make sense from a business perspective:

- You have a complicated product, and wish to break it up into more digestible chunks, with allocated teams working on each abstract business concept (Amazon and Spotify do this).

- You want to avoid having a single point of failure- if one service fails, the rest of the system might well keep on working. (Ever noticed how sometimes a panel on Amazon doesn't load?). If you're running a continuous development process, stuff breaks, a lot. It's good if that's locked down.

- You have a business requirement to build something with a different technology (from experience- rendering javascript in a node service was much, much easier and more maintainable than with an existing Django app- we tried both.)

- You want to experiment with new technologies without changing your whole stack.

I'm pretty sure that the author wasn't talking about moving to microservices so they can blindly start building every aspect of the application in a different stack- but more that if they need to use a new technology for their business requirements, or want to give something a trial without committing, they can. And with the uncertainty and rate things change in modern software, and in a startup, that flexibility is invaluable.
Yea, perhaps it's worth being explicit about it in the documentation, if it's not already mentioned.
Every car here has 3 heaters actually.

Block Heater: Like you mention, in the 500W range and heats the coolant (basically a kettle element)

Oil Pan Heater: A stick-on heater that goes on the underside of the oil pan, usually in the 200-500W range. It heats the oil, because past about -35C oil has the consistency of butter, even synthetic will do that past about -40C. If you have a big vehicle, you stick more than one on.

Battery Blanket: Like an electric heating blanket for the battery. If the battery freezes, it's done for, so you don't want that. You'll also get a lot more current out of a warm battery, which is critical when you turn the key at -40C and have to spin all that cold oil.

Everyone also puts cardboard or whatever in front of their radiator for the winter so when you drive on the highway the vehicle can actually get up to running temperature.
British Prime Minister Wants to Ban Encryption
I'm certainly no expert but I can take a stab at it.

I think the author was talking less about the syntax and more about the semantics of SQL there. Specifically the query plan. For instance in a SQL statement there is no indication which fields are indexed. You don't even have to use a primary key to find the data. So the database has to take both the data you provide in your AST as well as data about the tables and fields you specify to figure out where to find your data in a distributed database.

Contrast that with the redis example where the client must specify a key that redis then knows how to map to a shard. The logic is much simpler and easier to implement.

Redis has shards builtin to the method you use to query it which allows Redis to simplify the logic of distributed queries.

SQL does not have a notion of sharding builtin in to it so this complicates the query plan logic when it comes to sharding.

> So punitive, indeed, that some Muslim scholars - who are generally most reluctant to countenance the possibility that the earliest biography of their prophet might be unreliable - have gone so far as to question its veracity.

This is dishonest. If the author knew anything about how Islamic texts are analyzed, he would not have made this statement.

The fact is, there is a general consensus that this story is fabricated. When analyzing any Islamic text, the first thing to look at is the chain of narrators who relayed the incident. This is the first step when classifying a text as (Sahih -- sound, Hasan -- good , Da'eef -- weak, Mawdoo' -- fabricated, and more). Further steps follow.

In this particular case, the chain of narrators contains known fabricators and liars. As such, this narration is classified as fabricated, and carries absolutely no weight.
Congrats on the deal. I've been using Dark Sky for about a year and it compliments the longer term Weather iOS app fantastically.

It's a tricky one. Mine was not covered enough last week and it hurt. Most people use some kind of face mask like for skiiing. https://www.google.ca/search?q=ski+face+mask

I don't wear glasses and don't have a problem with dry eyes, though sometimes my eyelashes start to freeze together - it kind of depends how hard you're breathing and how much condensation is building up on your face. Some people wear ski goggles when it gets really cold - but mine are dark and no good when the sun is not up :)
Regarding faulting mechanisms, if you've got a discrete GPU on a PCI bus then it's a separate piece of silicon that handles the network protocol. The important point is that I don't believe that the GPU cores have to be able to halt execution and save their state at any instruction.

It's certainly true that SIMD instructions in CPUs have predication which saves you a lot of trouble. The difference is that if you have two instructions which are predicated in a disjoint way you can execute them both in the same cycle in a SIMT machine but you would have to spend one cycle for each instruction in a SIMD machine. You can look at Dylan16807's link for all the details.

I think the concern is simple, really.

People are going to be told (rightly so) to use `let` instead of `var`. If they do so too mechanically, and their code is structured in certain ways, an expression which could never before throw an exception in Javascript, `typeof x`, now will do so.

This is not the end of the world, by any means. And it doesn't add an exception into unchanged code, but it still is a legitimate concern.
The chemical compounds, for instance, are phosphorous this or that.

Yeah, of course there are tasks that can be executed with coarse-grained parallelism, that can take advantage of multiple threads. It's not embarrassingly parallel though like with graphics, where you have millions of pixels that can be shaded independently of all the other pixels in an image, per rendering pass. In an optimizing compiler, compiled functions are not independent of each other, because data flow analysis will affect code generation, so you can't just compile each function on a different thread and combine the results. At least on a per-file basis, compilation has an inherently serial bottleneck, and that's not considering that 1. not all languages have separate compilation and linking like the C family, and 2. even with whole program optimization disabled, the linking phase can be fairly complicated in modern linker, so you have yet another serial bottleneck. And if you're implementing an non-optimizing compiler, then even with the naive, completely serial compiler, the whole process won't take long enough for it to be worth going to this trouble.
> More than half of Japanese are single. 49 percent of unmarried women and 61 of unmarried men, ages 18 to 34, are not in any kind of romantic relationship.

So 12-24% of women are sharing men then? Or would this be an artifact of the age bounding and women pairing with older, not counted men?
Any reason you went with DD-WRT instead of OpenWRT (just curious)?
I don't really have a problem with that, to be honest--I certainly don't run an IPv6 network internally (and neither does anyone else on AWS) and IPv6 translation can happen at the edges.
Also, Python3 has a separate operator, "1 / 2" versus "1 // 2", where "/" is always floating point and "//" is always integer.

Python2 also has "1 // 2", but the "/" operator can be floating point as well as integer, depending on the inputs.
Building mobile apps since before the app store
In Whitehorse we have cable internet and TV, and you can get 100Mbps Cable for $140/mo with a 300GB usage cap.

All the internet is capped, which is the worst part.

As soon as you're out of town, you can only get DSL, up to a maximum of 15Mbps, though most people top out at 5Mbps due to distance from exchange. Checkout the only provider for more prices http://www.nwtel.ca/personal/internet/packages (I work for them...)

Cell phones are good now - 3G in pretty much every town, though basically nothing between towns. It's normal to do a 6 hour drive and only have coverage for 30 mins of that.

In the bigger cities there are rarely weather related interruptions - as must stuff is on fiber, though once you start getting out things change. Of course, if you're in a town of 100 people in or very near the Arctic Circle you have to expect you're not getting 100Mbps internet with no interruptions.... it's all about expectations.
Well, thats been tried and rejected by the user base. If you harden too much it becomes a real PITA to do anything productive (SELinux running in strict mode).

RHEL aims to be secure, while also remaining fairly compatible with previous versions.

Red Hat do have documentation on how to harden, but most users don't use it and instead turn SELinux completely off as one of the first configuration steps.

In many jurisdictions, it is on the tax authority to prove that a certain transaction was not using an at arms length valuation.

If Rothko paintings are usually valued at 15x the size of the canvas, multiplied by an arbitrary dollar amount, and the person who structured this has the evidence to back this up, good luck to the tax authority winning that argument.

I've heard stories about collectors buying up 10 Picasso paintings, 3 of them really wanted by collectors, and 7 of them being 'mediocre' (if you could call any Picasso mediocre). As a set, they can be sold for $100M. Even though the acquisition value might only have been $50-$70M.

That said, how do you value a rare painting? Should the painting be worth $1M or $10M, but it's just hard to sell, that doesn't mean it's not worth the actual value. Should you deny a tax deduction just because it's a very illiquid asset? After all, the same reasoning often applies to houses (and other illiquid assets).
