Curious, what are the worries you're keeping kids safe from? I've got two daughters, now 7 and 8, and since they were born they've had unmonitored, unfiltered[1] IP connectivity. My parents did the same (well, with BBSes at first). The only thing I've ever wanted to filter out is the "kids" stuff since it's often so bad (e.g., Netflix for kids has lots of dumb shit, or those Flash games my kids like so much are ... low quality.) What am I missing?

(If auto updates are on, that pretty much eliminates exploits installing malware. (Assuming no one's gonna waste a 0day to install some spam/ad junk.))

1: The only filtering is client side, an ad blocker so they don't grow up accustomed to adverts. And just for general sanity - the web's rather obnoxious otherwise.
I am curious about why you have to parse dates in different formats. Is it part of a web crawler?

Once I switched to python 3, datetime has been sufficient for my needs as timezone is also handled.
Didn't see this reply until now. I don't remember whether the repository is configured out of the box, or whether I added one, but I've gotten updates the last couple of times I installed OEL.

You may be right about their kernel, but I'm not interested in that. I run OEL because it's a copy of RHEL.

None of these activities, as you've phrased them, are particularly expensive. Doing them the way OP phrased them, i.e. the most expensive way possible, is what I think is meant by stupid consumerism.
Does mindlessly staring through the office window really calm your mind? I would imagine that's when day dreaming and other thoughts creep in.
Is 37signals really a "lifestyle company"? Sure the founders are not billionaires, but I think with the (what I assume are) 8-figure revenues they must have, they'd be considered more than "lifestyle".

Nice, "Error 503 backend read error". Before it went down I managed to get a €5 promise in edgeways :)
First thoughts are that I like the music presented to me post-launch. Will see over time how that holds up, but so far so good.

On-boarding was typically Apple. No frills, minimal signup screen. This is followed by the Beats-style bubble genre/artists selector. That screen was fun, but I was a little confused by the search icon in the nav-bar, which I thought would allow me to add bubbles, but seemed to just span out into something else entirely. I backed-out of it and just continued with the few bubbles I had selected.

Like I said, music quality and selection seems solid so far. The app feels rather big -- this may prove to be a plus or a minus, but at the moment leads me to want to explore it a bit, which is seems like a plus for a content app.

There are some new UI patterns I haven't seen in an Apple app before, particularly the minimize icon when you're in the song player -- which is a modal rather than push on the navigation controller.
They either release verifiable true information or they don't.

Their agenda is irrelevant, as is the personality of the people involved, their political affiliations, their haircolour and their dietary and or sexual habits.

And let's hope that others with other agendas and goals will do their bit and release as much or more information as well.

If you only accept facts from sources that are 100% neutral then you end up having to make up your mind without any facts at all, no news outlet, no journalist, no TV station and no editor is able to say that they have 'no agenda', in fact it is entirely safe to assume that anybody that sends facts out into the world has an agenda and wishes to further that agenda by the selective release of the facts that support their cause best.

Wikileaks has been slammed in the past for 'uncontrolled releases', which I thought were actually far more balanced than any kind of editorial control and or selective release.

In that sense they are damned if they do and damned if they don't.
I honestly thought this was going to generate a free logo and got really excited for some unknown reason? I guess I was wondering how it all worked, then I clicked through and it made way more sense. That was a wild ride!

Tick Tack time is getting over. :(
I think that for the most part Apple has the same streaming contracts as Spotify/Rdio/Pandora/etc.

There are still a number of albums/songs/artists missing that simply aren't available anywhere (Tool and The Great Gatsby soundtrack are two I always check).

But it seems that I should be able to mix tracks I own with streamed tracks, which is going to be the killer feature for me personally.

Having used Rdio for many years now, and Zune Pass previously, comparing apples-to-apples (no pun intended) with will be interesting.
Its the mom exemption where you don't need a license to cut a relatives hair non-commercially, and that existing legal framework collides with the current bubble of internet-coordinated-mom-replacement startups.

"Mom can you drive me to the mall?" and next thing you know governments are out to destroy a startup.
I never had a good experience using Ticketmaster. I doubt more tests is going to solve that.

We still get people coding haskell! I think for us it is difficult but we have to draw the line somewhere, as everyone wants their favourite language to be a top category.... not sure how best to solve this at the moment!
I'm not sure how you arrived at this 3750 per second number.

Processing 1.5 million messages for ⅓ of the time (1500000 messages / 30d / 8h / 60m / 60s) is an average of 1.7361 messages per second during those 8 hours per day. If the remaining 500k messages were spread evenly over the remaining 16 hours a day for a month, that's an average of 0.963 messages per second ((((500000 / 30 / 8 / 60 / 60 )×2)+1.7361)/3) over the entire month.

Even if you were to process 1.5million messages during the last 8 hours of the month, that is only 52.08 ( 1500000 messages / 8h / 60m / 60s ) messages per second during that 8 hour period.
I think they meant they're sorry that you previously had to manually find the file/line after an error.
Introduction to machine learning with R
Sounds like what's needed is a bunch of high altitude blimps or cargo planes with air-to-air missiles.

And enough countermeasures they don't get picked off by ground-to-air missiles.
(I'm agreeing with the parent post, just elaborating.)

Also, much like the weather, sometimes you can only make accurate predictions if you make a small prediction and correct it once you get feedback.

Much like you can get insanely high correlations on your predictions about the weather if you never predict more than 15 minutes out, the problem of predicting the other plane's response only become tractable when you can predict and correct over very short windows.

The higher clock rate doesn't just do more of the same faster, but rather, enable a sort of "phase shift", where the speed enables a new form of computation to work in a meaningful way.
Jerry Brown signs California vaccine bill
Airbnb killed short term rentals category.

42floors is killing the commercial rental category.

OKC/Tinder killed the personals category.

There are three main categories keeping it alive: apartments, jobs and for sale. Each of those categories are under attack from semi-successful startups but no homeruns...yet.

If either For Sale or Jobs categories get an airbnb-like competitor, it will be a massive blow for CL. The former is its largest category. The latter makes it all the revenue. My hunch is that its Jobs category is already under attack and they are having a harder time making revenue resulting in their aggressive legal battles.
They have had all their recent APUs and GPUs fabbed at TSMC on its 28nm node. Dunno what their most recent GF product line was, last I remember was Richland 3 years ago.
A new Cochrane meta-analysis is much more likely to make me change my mind about some empirical claim than a fresh study.
That's correct. The interface though is not separated. The client software that is running on your server seamlessly connects to our cloud to provide you with the management tools needed. You can call it a proxy, but a much smarter one.
I have a 128g 6+, for whatever reason on just one wifi network when I activate the vpn, I can reliably blue screen the phone.

Looks interesting, but not very clear how to submit an item. I'm guessing I'll have to register, but will probably be more engaging and clear if you can encourage people to submit something and then walk them through any registration.

Otherwise, I'd love to submit Kenhub[0]. It's a learning platform focusing on Human Anatomy, featuring articles, anatomy atlas, videos and interactive quizzes.

My most memorable interactions with potential employers started with a handwritten cold email from a tech lead person of the company, mentioning something about my github profile (which shows they took the two minutes to do some basic homework on their end).

For closing the deal, however, I look for good pay (e.g. don't offer me equity in lieu of money, especially when some quick research reveals you're also receiving candidates from recruiting agencies) and I look for a good fit (e.g. culture/policy of reasonable work hours, I'm allowed to - and encouraged to - hold intelligent discussions with the team rather than wasting my time w/ HR bureaucracy or googleable trivia, etc)
I can't tell you how many times I've had to help people who switched away from their iPhone and then saw eternal, intermittent issues with not receiving text messages because their friends iPhones were convinced they should be sending iMessages and not SMS.

This isn't trying to scrape the page and find something vaguely logo-like. Rather, it seems to be using iOS, OpenGraph and Twitter icons. In this case, the site has a strange OpenGraph image specified in its meta tags. If it produces a weird image it's because the site owner has specified an image which isn't their logo. It's not because the API picked a random image.

For this service, if it can find an image, it's at least an image the site owner wanted to be used to represent it.
So what _is_ the reason? I have always assumed that this is an example of regulatory capture: existing barbers gain from raising the barrier of entry for competitors, while non-barbers don't care enough about it to lobby.
Also that some Dutch companies are involved in producing parts for the F35. At least 70 Dutch companies are supposed to be involved in producing parts for the JSF. And perhaps the unconfirmed rumour [0] that US nucleair weapons of the cold war are still stationed in the Netherlands have also somehow contributed to the choice for the JSF.

I think you understood this, but I wanted to clarify for others: the Cochrane review that this article is about showed that fluoridated water may not prevent tooth decay. The 2009 review you mention does not contradict this, since it is about fluoridated toothpaste, not water.

None of them have shown any desire to support open firmware. Intel makes SSDs, Wifi cards, CPUs, and motherboard chipsets that all have binary blob firmware you cannot audit or trust.

AMD really only makes GPUs with blobs, and that is probably more in the ATI legacy than anything. They have been pretty good about coreboot support of their vanilla chipsets for years, even if it is usually delayed several months to a year post release.

Expect()ing the Unexpected – When Components Clash
LTE-U is coming to take your Wi-Fi away, consumer advocates warn
Did anyone expect it to do so?

Fluorine production was a proxy for uranium production if the only use for fluorine was for uranium production. Couldn't have the Soviets knowing how many atom bombs we were building, so we needed to use it for something else too. Something so massive that it would make it impossible to calculate how much was used for nukes. And so we put it in the water supply as an additive.
I've said this before, but it's worth saying it again. It's disappointing the two most popular OSs are a Unix derivative and the bastard child of VMS.
Well, contrary to the other comments in this thread. So far I've been enjoying it for about the hour I've had it on my phone. I enjoy the UI more than Spotify/Rdio (Although I only used Rdio for about a week.) It has artist I enjoy from Pharrell and Eminem to DJ Okawari and Major Lazer (although I guess they aren't as obscure anymore.) So far listening to Zane Lowe on their Radio channel has been entertaining. Do I think I'll leave my playlist from Spotify to come to Apple Music? Possibly, I have 3 months to figure that out, and currently I can't say I'm disappointed in the service?

Although I will say I'm hoping apple does more with the whole Music Connect and actually following artist that Spotify and other services currently don't, I'm going to hear about the new album regardless of whether or not I follow them on your service, update me with interviews they do, or if a concert is in my area, rather than just updating me whenever their album eventually hits your servers.

The way they handled security when that guy made shellcode for IOS was pretty reprehensible. Apart from flat out refusing to believe it at first, I believe they tried to get him fired as well as using legal tactics.

And in licensing model, be sure to include adding checks to lock out fair competiton ("genuine" checks). There's probably some other shitty things they've done that I'm not recalling ATM.

But otherwise? Well I probably am partial to what I first learned. But I recently tried Fortinet, and the configuration is so braindead stupid, I felt bad for all the times I got annoyed with Cisco.
One is an open source platform, the other is a commercial entity. The worst thing you can do is to complete depend everything on a product by a company. If they decide to kick you out, you can't switch over to something else easily.
It's more the context of the piece I take issue with. e.g., the fact that they call out critics for saying the program is behind schedule by linking to a piece they wrote quoting a civilian contractor saying he's very confident they'll deliver a specific component on time... that was written about a month before Lockheed announced more overall delays.

I'll keep an eye on them, but the handful of articles I've read through so far definitely feel like they've been run through a PR filter rather than a reporting one and that's not just limited to the F-35 coverage.

2000hrs of barber training
I, uh, am pretty sure that no one in Brussels are used to having the last word on anything. That's why everyone moans about the place.
The reason is that barbers have sharp things and deal with many people. Also lice. There's a very real public health risk if done incorrectly.
I agree with the Parent - Spotify is screwed. I've only had 30 minutes with the Apple Music app, and it's awesome. I mean, it's not just an acceptable substitute (which Apple Maps for anyone who took a bus wasn't for 2+ years), it's a serious competitor - that's included on every iPhone by default

I'm willing to wager by end of year, Apple Music will be used 2x more than Spotify on iPhones. That is, I'm guessing by end of year Spotify will have stalled at around 25 million paying subscribers, and Apple will have around 50 million+. And the curve for Spotify will be flat, or descending, while Apple will still be arcing up.

I guess we'll see though.
>"I hope you’re convinced. A hash is simple. A hash is fast. A hash is all you need."

Hash tables are cool but they are far from being the only thing you need.

The problem with this kind of subtle satire without a disclaimer at the end is that some people would fall by this and blindly follow it (collisions weren't mentioned not even once nor cache misses).
Ask HN: How can I learn Haskell?
I've had enough people mention the benefits of learning Haskell that I've decided to take the plunge. I'm very interested now in Functional Programming and want to "level up". I've taken the Intro to FP and Reactive Programming class on Coursera and loved it, but also know I have alot more to learn.

There's a ton of info online about this question that I'm feeling a bit overwhelmed.

Any tips or good resources that the community can recommend?
Iirc, a transaction has some number of ongoing and outgoing things, and the part of the ingoing things which don't go to outgoing things goes to the miner of the block that includes the transaction.

The specifics of that might not be quite right.

But a transaction generally specifies some amount which goes to whoever mines a block which includes the transaction.

If one wants their transaction to be included in a block more quickly, one can include a higher transaction fee, so that miners have a greater incentive to include your transaction in a block compared to other transactions.

I am fairly sure that the above is basically correct, but not entirely sure.

I don't actually own and have not used bitcoin, I'm just interested in the space.
Why we raised a small round (and why you should think about doing it too)
> all Linux distributions are tuned for nothing in particular.

Which is good, because often tuning means making trade-offs. A lot of those things like polling and interrupt shuffling have side effects and might for example negatively impact other scenarios -- presumably not everyone out there is running single client-server ping-pong with small UDP packets.

Yes a lot of parameters have retained default values from back in the day when system characteristics were different. Switching defaults drastically might break existing code that relied on them. Perhaps those are better updated during major distro version upgrades (RHEL 6->7 for ex).

In general though, I would say Linux is tuned for average throughput not latency. Sometimes they go hand in hand, sometimes they don't. Over the years there have been patches and forks related to operating on low latency environments (stock trading, media processing, hardware control, graphics in desktop environment). Those range from parameters tweaks in /proc to kernel patches, to almost full kernel bypass via things like DPDK for Ethernet for example.
There are of rules for proper sanitation and safety, as well as continuing education requirements that are enforced through licensing.

Just so everyone is clear: this review found that there is little evidence that water fluoridation has any benefits. It does not dispute that fluoride in toothpaste reduces tooth decay.

> Studies that attest to the effectiveness of fluoridation were generally done before the widespread usage of fluoride-containing dental products like rinses and toothpastes in the 1970s and later, according to the recent Cochrane study. So while it may have once made sense to add fluoride to water, it no longer appears to be necessary or useful, Thiessen says.

> It has also become clear in the last 15 years that fluoride primarily acts topically, according to the CDC. It reacts with the surface of the tooth enamel, making it more resistant to acids excreted by bacteria. Thus, there's no good reason to swallow fluoride and subject every tissue of your body to it, Thiessen says.

> Another 2009 review by the Cochrane group clearly shows that fluoride toothpaste prevents cavities.
"Hashes are always O(1) reads, inserts and writes."

Maybe, once you've found a location to read, insert, or write to. The author neglects the runtime cost required for the hash algorithm itself, which may not be trivial; computing the hash of a string key is typically an O(n) operation.

Furthermore, unless a suitable table size is selected, integer keys (should one use a map like an array) will eventually hash to the same value, requiring even more time to iterate through all the remaining values that match that key until the desired value is found.

"I don’t know why you would ever use [a linked list] over an array (or a hash)..."

Here's why: because arrays take up space whether you use it or not. Linked lists don't suffer from this problem, but at the cost of 1-2 pointers per item. Has the author seriously never managed memory before? Please tell me this article is a joke.
