Regarding bras:

If you had your boobs made, they're probably pretty close to the exact location and proportions that bra makers expect. But if your boobs are broad rather than projecting; or set closer or further apart than the typical bra in your size... underwire pokes in all the wrong places. (Don't get me started on all the assumptions built into women's clothing and bra sizing.)

Plus if you've got an extra layer of fat on your torso or wear it too tight, the band can dig into your skin. If your band is too loose and you have big boobs, the weight falls onto the straps and hurts your shoulders.

That said, a lot of women who find their bras painful are wearing the wrong size.
>reasonable worst-case behaviour (think real-time apps, or adverserial scenarios)

I'm not sure I agree. When faced with potentially adversarial input, a hash should be keyed. And, depending on the specific tree, you can probably cause a lot of havoc by causing repeated tree reorganizations. Even worse, you have a timing side-channel, because node-split and node-merge are expensive, likely measurable over the network. This can leak info about existing adjacent keys in the database.

This kind of attack is afaik not as researched or well-known as hash collision based attacks, but in my book that is a point in favor of hash tables with keyed hashes.

On the other hand, both approaches shouldn't play in the same league: If you need to support range queries, then you need to support range queries.

>And the speed boost from locality gets more dramatic every passing year as the memory gap keeps widening.

This is true for scenarios where trees save cache misses (e.g. if there is a correlation between order of queries and location of keys). The linked comparison explicitly compared L3 misses between various trees and various hash tables for various scenarios, and the hash tables come out better in that metric.

All that being said, ART is pretty cool and node16's branch-free SIMD search is amazing.
A society without cash is a society in which every person has no choice but to get the permission of someone they don’t know and will never meet each and every time they seek to obtain food, water, shelter, or transportation, and that permission can be revoked instantly, silently, and invisibly at any time.

As someone who uses nicotine a couple times a year, largely flavored cigars, as a self prescribed mood stabilizer rather than a daily addiction I would like to say there are drastically life improving upsides.

When I have had an abysmal day, it can make everything seem ok and even stave off a panic attack.

When I am flying off the handle in anger it can calm me right down.

It can do this without dulling my abilities - actually improving them - unlike other legal and less than legal alternatives.

Is it prone to abuse, particularly in certain people? Absolutely. Is nicotine, particularly in conjunction with tobacco a carcinogen? Absolutely.

But to say there is no upside is dishonest.

No, not ironic, that's precisely what he doesn't do; he says you probably need 5-9 shades of each colour group - Primary, Secondary, Highlight, Greys, etc.

He also says the reason you can't write a generator is because every colour looks different and needs to be judged by your eyes.

How exactly? What in the definition of the app market is disingenuous.

If "browsers" were a market at the time of the Microsoft anti trust ruling, a $70B app store space is very much a market according to prevailing economic theory.

You just don't like the truth about Apple, which is understandable, as they're a loved brand. But evil
Pretty sure all those "benefits" come from big tobacco-backed research. If nicotine is a stimulant, it's a crappy one.

Do you program for a living or have a job that requires lots of human interaction? I find coder jobs amplify the unbalancing nature of loneliness. On the other hand , loneliness is just a symptom of the human not knowing how to be alone and remain content. If only we were born with the user manual around our neck
Haha! The display was also behaving strangely so they gave me a completely rebuilt machine. i.e. none of the parts were the originals.

Oh and I should have said originally I'd already dropped something on the screen which shattered and they did charge me the £700+ for repairs at a previous date.

It does make me question how long this machine will last and if I should sell it while it's pristine before anything bad happens to it...
(Author of Badger here)

First of all, thanks to the growing Go community for using Badger. Within a short period of time since the original announcement [-1], Badger has become very popular.

A lot has changed since the original post. Despite being tagged as a non-goal at the time of release, Badger now runs concurrent ACID transactions providing serializable snapshot isolation guarantees.

In fact, Badger is being used to serve Petabytes of data (yes, PB, not TB). On my long TODO list to write a blog post about it. It has stood the test of time, being directly used by the community and Dgraph [0]. We have put it through many different crash testing scenarios, including ALICE[1], and run Jepsen style bank transaction tests every night for 8h [2].

There're some common questions around benchmarks on our blog posts. They were done before Badger had transactions and are somewhat old by now. But, Badger's read-write performance is still spectacular. In terms of write throughput, it outperforms RocksDB (called from Go), LevelDB BoltDB, and in terms of read performance, it goes neck-to-neck against B+ tree based DBs, which typically perform better than LSM trees. Recently, there was a benchmark by Ethereum 2.0 folks, which I ran [3]. You can see the ASCIInema here [4].

There's an open bounty of $1337 on Badger to help us find scenarios where Badger could lose data [5]. So, if you got ideas, throw them in!

Thanks again for using Badger!

This[1] is the one I bought. It is now sold out from that particular seller. It was $180, not $160 as I said before. Being on AT&T seems to give the widest array of purchase options in terms of carrier lock.

The box was sealed, serial number was valid and unused (Apple can confirm this) and the warranty is valid as well. Buyer beware, there are some sketchy sellers on Amazon but if it is "fulfilled by Amazon" I would expect no issues with a return.

If you're going to make something almost totally unrepairable, you'd better make it almost totally reliable as well.
A prediction of Apple losing its dominance "over a couple of decades" is useless. It's almost guaranteed to occur at some point by statistics alone, in exactly the same way as any single wine glass in a restaurant will eventually be dropped. Plus reversion to the mean, obviously.

And the fate of Samsung, (and some other company I can't even remember but that was dominant for Android phones before that) shows that the Innovator's Dilemma just doesn't apply, at least not yet. The theory's whole stick is that it describes a mechanism that cannot be defended. That's why it's termed a "dilemma". Apple has successfully withstood dozens of attacks with low-end generics, showing quite clearly that this is currently just a regular market.

Samsung and other competitors also show that it's ridiculous to analyse this market in time frames of "decades". At that resolution, it's quite likely that, when the history of this market is eventually written, Samsung wouldn't even show up! The rather wild swings in profits and market share of all competitors also show that for the market segment in general, a single year (which not coincidently aligns with the product cycle) is the adequate granularity. It's only Apple that somehow manages to show a rather strange stability among this volatility.

Yeah, there’s always a guy in one of these conversations that can’t imagine working in an office with people talking to their computers. I guess you get to be that guy this time.

The other guy is the one who will never talk in public to a computer.

Finally, you have the guy who can’t imagine not using a keyboard to program.

For the rest of us, we have no problem talking to our computers, and we anxiously await the future to arrive.

The list of companies you give doesn't quite work. Bell Labs and Xerox Parc were small organizations within a larger company.

The vast majority of people in the companies you listed are doing work that has nowhere near the density of interestingness that happened in Xerox Parc, for example. There might be individual departments in those companies that are comparable -- in Microsoft Research perhaps, and a sibling comment points out Alpha Go.

Anyway, the point is: Working at Alphabet or Intel or any of these is nothing like working at Xerox Parc, unless you happen to be in a very special place within those companies. But then, such special places are bound to exist elsewhere as well, in particular in small startups that are doing genuinely interesting things.
> why couldnt it be part of a bigger impactor, so if it was just a shard that broke off after impact and flew mostly horizontally before settling?

I agree, there could be any number of explanations. I haven't seen many meteoroids but the rectangular shape appears peculiarly unnatural, more like a fragment of a shell.
"Remarkable" does not mean extraordinary, it means worth remarking upon. Hence the old saw in Philosophy: "No remark without remarkableness." There is a connotation of surprise, in addition, but surely surprise is warranted. I am very willing to believe that there's some difference in usage on different sides of the Atlantic, but doubt that difference is extreme, in fact it may not even be remarkable.

Note that the response you got was that others aren't reliable when extracting statistics from articles, so while you may be very reliable in this way, they can't trust users to do this and have had to draw a line.

I too hate clickbait (unless it's a headline I wrote, of course) but "remarkable" doesn't trigger me.
You have to backup the thing before giving it to Apple and I format the thing too.

> The development raises some crucial issues regarding the state’s role in the payment market. For hundreds of years, the public has been offered central bank notes and coins. If cash stops working, it would leave all individuals to rely on the private sector alone to get access to money and payment methods. This would be a historical change without precedence. Norway is seeing a similar trend, and the two central banks are cooperating in this area. In the Eurozone, cash is still used to a high degree. The value of the outstanding amount of cash is equivalent to 10% of the Eurozone GDP, versus the Swedish equivalent of only 1%.

A government system ideally guarantees access to every citizen/entity desiring to possess "cash". A system run by a private entity doesn't have to do so. If you don't agree/fall out of compliance with the terms of service of a private system, you can be banned. The same can be done on a government system, but at least you have the option of court intervention and voting people into/out of office.
For contrast, I went back and read Brendan Gregg's explanation of heatmaps and found the concise explanation of the mechanics clear and easy to understand:

TBH, the Honeycomb overview felt long and difficult to get through. Does anyone argue against heatmaps and demand a case be made justifying "why heatmaps"? This read like it was fighting hard in defense heatmaps; against who I'm not sure :)
Men at least can get shirts with shoulder, chest, and waist in any combination of proportions. Women just have S/M/L, never mind that not only do our waists vary in thickness relative to our shoulders and hips but we have an enormous variety of boob sizes.

Men never have to worry about the buttons of their shirts busting open across the chest. For many women, that's a constant struggle if they want to wear something that isn't 3 sizes too large in every other dimension.
As a resident of Sweden, i can only say that this is the future for all western countries. Life is just better without cash. We don't pay the mental tax of always ensuring i have dollar bills on me to tip left, right, and center. Your phone is enough to get you through the day. The govt is still run by the people for the people here, so most people aren't worried about totalitarianism. Most beggars now have signs with their phone number to swish them cash - because nobody has cash to give them (the other form of begging is collecting plastic bottles and cans with deposits).

> Smoking in the center of cities on the street should be illegal (like it is in most of Australia), because it causes harm to complete strangers.

I understand that secondhand smoke indoors is dangerous to others, but is there any real data on outdoor secondhand smoke?

How does it compare to the liters of exhaust per minute from diesel engines in trucks passing by on those same streets?

Perhaps more generally, at what ppm does second hand smoke start to have long term effects on unwitting participants, particularly compared to other major sources of toxins and their concentrations in an urban environment?

[edit: to be clear I’m genuinely curious, not trying to dismiss it or whatabout it. I’ve always thought most second hand smoke issues could be solved with good ventilation (aimed at properly exhausting the smoke) and it seems to me that trace amounts from smokers you pass by on the street are a completely different situation from sitting next to someone smoking indoors]

Mine are natural from years of estrogen, though I probably have a wider chest. Getting properly sized bras I don't even notice they're there anymore. If I get one that isn't sized right, it can actually leave bruises and make me want to scream during the day. I have also heard a lot of women are wearing incorrectly sized bras.
I agree, but the main point of an e-krona is exactly to try and reduce that risk.

One of the proposed goals is to have non-traceable transactions. Seems unrealistic to me but that would be the holy grail.

Irc, is still around. Usenet is probably still around (was 7 or so years ago) and, who knows, maybe The Well has some interesting things happening.

You don't have to take the top result on google.
And you might be leery of criticizing any of these entities lest they withdraw your ability to do any of these things. That's a serious chilling effect.
It looks like the meat starts at section 9.

- Sections 1-8 are a summary of REST, HATEOS, their problems, and reflections on the problem that every endpoint is `application/json` and not something more specific to the intended use case.

- Sections 9-11 discuss a variant of REST that doesn't use Media Type differentiation for capabilities, but rather composable nuggets of semantics called MicroTypes. The MicroType schemata is accessible through an introspection interface; one suggestion is to use (cacheable) OPTIONS. Clients would transmit their desired MicroTypes to an endpoint using the Accept-Type header.

If I'm reading this correctly, the author is suggesting the clients be allowed to specify the middleware chain used by the server to compose the response data (cf pagination, query, filter MicroTypes), and that these programmable chains are attached to every traditional REST endpoint collection. In one sense, this is an attempt to marry the resolver chain concept from GraphQL into the world of RESTish JSON APIs.

I think you could pull this off only with a dedicated server library because I don't see real world developers using this technique successfully on the current crop of HTTP webserver APIs. There's also the very real performance issues that come up when clients are allowed to control resolution; we see companies using GraphQL in production locking down the ability to do custom queries.
I'll take a bold guess and say that it makes you frustrated, because you've never worked on anything very difficult, and as a result, have unrealistic expectations of what that process is actually like.

The folks behind LightTable/Eve have a commitment to living their life as they see fit. That's it. They had some ideas they wanted to work on. If you want to support creative people doing creative things, you give them money.

That's it. If you want creativity, you have to give and not expect anything in return and when it works out, that's great!

You may be confused by established companies that were once creative, now doing incremental improvements every year, selling it as creative work. It creates an unrealistic expectation of what the creative process is actually like - full of things that didn't work.

1. (author) That's how WiscKey did it. But, they omitted a lot of details around how an online value log garbage collection would work. Offline GC doesn't work for most users. On top of that, Badger supports 3-dimensional data access, i.e. key-value-versions. The version axis is supported natively, not overlaid on top of an internal versioning.

Supporting versioning while also doing value log GC is a very tough challenge, something that has taken us many iterations to get right. And there're still improvements that we can make, and users ask us for.

2. Skipping, another comment tackles that.

3. Using a hashtable would not give you sorted iterations, something that many users use very heavily. A 15 min thread idea would work a lot worse than LSM tree, just by definition.
Hi, If this is going to be your intro into programming, codeschools may not be a good first step. They may say you don't need any prior experience, but typically they drop those people out if they aren't doing well so it doesn't mess with their metrics. Honestly, it may take a bit more time, which can be a good indicator if you want to work in this field, is to find out what a local community college is offering for courses and sign up for one programming class. You'll often find that you have time to learn the material and put it to use while being in a classroom setting where the class size is smaller and the instructor can walk you through tripping points. Plus it will be way cheaper. You'll expand your network there too and maybe get a good reference from the instructor who has industry contacts. Any career is a marathon, some people can sprint the distance, most can't. Don't set yourself up for failure from burnout.
Central ledgers long predate blockchains and are widely used, i.e. by all banks.

The only 'novelty' here is that it'd be run by the central bank and accessed directly by consumers.

> When the church ruled the roost the important people in the church would be wearing clothes that we recognise as robes but are essentially women's clothes.

FYI, that’s because Christian vestments are descended directly from men’s clothing in the late Roman Empire, where men who weren’t clergy also wore robes. I don’t think they were “women’s clothes” unless you define all robes and dresses to be female specific.
