I tried Imzy, but I can't like it. It's not forum-ey enough, draws too strongly from social networks: if your forum looks like a social media site, you won't have good discussion: that interface isn't optimized for it.

a.f.p on the usenet (that's alt.fan.pratchett for the uninitiated) used to be good, but it seems to be nearly dead now. :-(.

Bits of reddit are good. I love /r/adventofcode this time of year (although that's seasonal and event-specific).

If you're looking for proper, real, actual forums, I can reccomend a few. The xkcd forums are still excellent, give or take. If you like dwarf fortress, the bay12forums are good.

And onto the chans: much maligned as they are.

4chan's /tg/ is shockingly good if you like tabletop games (WH40K in particular): it's a blue board, so it's not totally flooded with porn constantly, and it's also got a decent community and isn't horrifically acidic, unlike, say, /g/.

Also, even if you don't like the chan, the wiki, 1d4chan, has a tvtropes-like stickiness about it, essentially being a best-of reel of the entire community. You should at least read The Tale of Old Man Hnderson, as it is one of the most famous in all of RPing.

7chan (http://7chan.org) was created as a reaction to 4chan, and it shows. Posting quality is enforced, and the mods are quite punishing. But as a result, quality is reasonable, AFAICT (although I am not a regular)

Sushichan (https://sushigirl.us) is a "relaxed" chan.

And than there's Lainchan.

Lainchan is a cyberpunk chan (sort of). It also has a strong programming and anime focus (with a name like lainchan, would you expect anything else?) It bears a semblance to HN in some ways, but it's a chan, make no mistake, and quite different in others. Just go look if you're interested.

Of additional interest is lainzine (https://lainzine.neocities.org), lainchan's official unofficial magazine. The typical immidiate reaction to lainzine, AFAICT, is "what the hell did I just read?" and I speak no hyperbole in saying that it is like nothing else on the internet.
This is a desktop app, "where the users are" isn't a compelling argument because it could be in practically any language and have the same barrier to entry.
And here you see the problem in the US having a fixed inauguration date.

In parliamentary countries, where the government can vote to dissolve itself, they tend to call for elections whenever the governing coalition is unstable, and elections can take as long as needed, and be re-held as needed.

I misread your reply on Lenski's experiment as dismissing it as not an example of evolution, rather than as not an example of speciation. The first would be incorrect, the second is more of a judgement call which calls for discussion.

If you did want a similar example in the same vein where speciation unambiguously occurred then one of Lenski's students just did a great experiment that shows that. I highly recommend reading it, it's a great paper. http://science.sciencemag.org/content/354/6317/1301

That seems like an excellent outcome, if you don't assume that only the NSA knew about the vulnerability. EU countries are our allies, after all.

In any case, our foreign intelligence would still be intact, if the NSA had restricted itself to that. Once it crossed the line into secret domestic mass surveillance, it made itself fair game for idealistic dissenters.
On the one hand, I don't psychological services industry has really demonstrated an ability to treat psychological problems in a consistent, effective fashion.

On the other hand, I would claim one can see a strong correlation between declining incomes and increased psychological distress in this society - the suicide rate approximately doubling in the last twenty years - not this is a direct casual effect.

Which is to say that easily available, acceptable housing - hotel rooms rather than shelters as suggested in the article - is better solution for people, psychologically distressed or not, than more psychological services or better psychological services. And also, if someone's on the streets, no amount of counseling (or drugs or whatever) is going to solve much if they stay on the streets.

The thing about skipping the news completely is that it's dependent on you not being impacted by a black swan event that significantly and negatively impacts you. The White émigrés from Russian in the early 20th century and the Jewish refugees from Germany in the 30's show clearly the value of paying attention to the news. Not doing so can cost you your life.
No, that's literally 100% Apple. They could've very easily shipped the higher specced cables for what amounts to a rounding error in the total overall cost. They just chose not to in order to sell more cables. They can now tell people that a cable is "only compatible with model X" - when in reality the 15" pro cable is compatible with all 3.

> “Being concerned” makes us feel like we’re doing something when we’re not

Corollary: retweeting about being concerned also does nothing. That is, retweeting about climate change won't reduce emission. It might feel good but does nothing. Retweeting about homelessness and telling everyone to be concerned about it does nothing to clothe, provide shelter or food. The article mentions about a substitute effect and I think it is even strong when it comes to spreading concern via social media, there it feels even more like "doing something".
One visit to carm.org or reasonablefaith.org with any questions outside the parameters you've set and you'll see there are ample examples to the contrary.
Progressivism is tricky -- the definition of the word is for continual change. So, no progressive agenda of Year X would be progressive in Year X+20. A successfu progressive in Year X would be pushing progress the margin choices of the day. In Year X+20, a different set of choices are at the margin. No effective progressive in Year X would have the same agenda in Year X+20.
I already told you what it took in numerous projects plus one company's regular work to deliver low-defect software. Vastly lower than that. That means something is missing in either your data ir mine. Thing is, the NICTA papers clearly tell us why:

1. They were mathdmatically proving equivalence of spec, security policy, C code, and assembly. Latter two were state of the art methods requiring more time and brains. Not necessary in most projects to achieve low defects or 0-days.

2. The methods were new. When that happens in formal developmemt, most of the work goes into building tooling and even figuring out how to apply the methods to the class of problem. The seL4 and L4.Verified reports said exactly that predicting that reuse of that tooling would drop cost dramatically. It did drop to a quarter later with COGENT. LOCK, Cleanroom, Praxis, etc reused existing tools and methods where possible to avoid huge costs.

3. Cleanroom, Eiffel, Ada, or even Haskell all cost similar to regular development in commercial use despite knocking out many issues more easily. That they achieve low defects and cost should already establish my claim (strong QA is affordable) as baseline.
Sounds like delayed delivery of messages?

If the buffers are filling faster than the servers can clear them, then you're headed for "catastrophic" failure anyway and notifications are going to get dropped regardless. You can handle it more or less gracefully while you spin up more capacity.

The other choice is to always keep around more spare capacity, but that can get expensive if as they describe these drastic peaks happen once a month.

Exactly this. There is absolutely no technical reason that Apple could not ship one cable that works on all adapters, it would be overkill for some and just right for the high end one and the difference in money would be trivial compared to the support calls from people who can't get the cable to work or it fails while they are using it.

Ask HN: Who crawls websites on a regular bases and why?
Hi folks,

I'm thinking about building a web crawling service very similar to kimonolabs. Before I do so, I'm trying to figure out who my target audience should/could be.

I started off thinking about a tool that I would personally use which is sort of a web polling trigger. For example, login to website A, sort a list by relevance, check if the first item on the relevance sorted list is greater than X, poll until true (once true, send an email/send an sms/make an api call), then login to website B, insert item from website A into an input field and submit. If I were to start off with this, who would use it the most? (Maybe a financial analyst? investor? Sales? Market Research?)

I've also been thinking about building the service particularly for data scientists/analysts. Some features would include visualizing datasets, clustering analysis, sentiment analysis,
relational & and non-relational database modeling (similar to MySQL work bench) directly in the browser, integrations with IBM Watson (https://www.ibm.com/watson/developercloud/personality-insights.html)

I don't think they sell the 12" MacBook cables stand-alone; I went to the store to get a new one, and they just sell the beefier ones. I personally think the problem is that the 12" MacBook was a test run of USB-C, and the cables they shipped for that ended up not being good enough to handle the needs of the new laptop they didn't ship until a year and a half later.

Even with passive devices, there's a risk that it's miswired and will connect things that should not be connected to each other. Most famously, earlier this year the Google engineer who reviews USB-C cables had one fry both his Chromebook and USB-PD analyzer.

Regardless of cash, does Apple have the reputation to hire and attract the best? I am assuming so.

With the recent missteps, maybe you're right. It seems like they currently don't have enough talent to steer such a huge ship.
I am pretty sure you can use the cables that are designed to support the higher wattage chargers on the smaller devices (and that's what I'm doing right now: Apple doesn't even sell the crappier cable the 12" MacBook shipped with a year and a half ago standalone right now, AFAIK).
It would be in isolation, but it would also make it hard for people to replace that income if they came to depend on it.

You're right, and I'm surprised (and concerned) that there haven't been any retractions or errata published for the paper cited. That said, the sentence-to-vector and paragraph-to-vector models are obvious extensions of Mikolov's original word2vec architecture (the performance of which has been extensively verified by people all over and by a myriad of reimplementations), and I can attest that they've outperformed traditional text vectorization techniques (different bag of words parameterizations, largely) as features for every task I've evaluated them on (can't be too specific publicly, unfortunately). I guess what I'm saying is that ideas can be decent in spite of a poor first implementation.
> The current shelter system very often warehouses people in conditions that would not be acceptable for any kind of paid accommodations, whether it be temporary accommodations (like a hotel) or permanent (like an apartment or house).

I'm curious how homeless shelters compare to (paid) hostels, which are far more economical than hotels. They're (I assume) both in a dormitory setting.

Hotels are obviously not economically feasible as a long-term solution. I think the risk of this proposal is that they are not a reasonable on-ramp to society, as even if you can get a stable job you almost certainly cannot afford to live in a hotel full-time. On the other hand, some sort of hostel-style accommodation would be reasonable.
