I also agree with the article author to give them a take home project to work on. Just saying that a computer science degree and a 10 min chalk board test are a pretty terrible way to make new hires.
As someone with a computer science degree I can say I've never questioned it being on my companies job postings. But when I think about it I'd rather see a candidate with an excellent github account than a degree.
"I hope to see the industry improve in this respect, but in the meantime I'm happy to exploit this imbalance as a competitive advantage."
I wonder how much of requiring a computer science degree is simply because the people hiring have computer science degrees. Seems like a self perpetuating insiders club.
This is the company the FBI supposedly contracted (http://www.cellebrite.com/Pages/cellebrite-solution-for-lock...), if that's the case it's just older devices that don't have the secure enclave which is not surprising.
This bummed me out as well, but it's worth noting if you have an Apple Watch that has a barometer in it.
Most retail accept them through companies like coinbase or bitpay but they immediately convert them to USD so their exposure to a bitcoin hack is minimal.
The reason they do this has more to do with the fluctuating price though as they can't risk the value dropping after they sell something.
SHA256 is used for mining but that would only expose new coins that are being generated. If there was a vulnerability there the community would switch to a new mining algorithm to secure new blocks.
Addresses are protected by hashing a public key to the bitcoin address (https://en.bitcoin.it/wiki/Technical_background_of_version_1...). If you've always sent coins to new addresses like the hierarchical deterministic wallets do then your public key is only exposed after you spend the coins, so you are not susceptible to a cracking attempt on the public key.
Yeah, I just pulled the title from the github issue.
I got it and liked the image for the project, I just think it's a little crazy this is a controversial issue and wanted to see what hacker news thought.
That's a pretty good comparison. In both cases you are adding warmth to a source one via software and the other via an amp.
A counter argument I'd give is has anyone ever described a TV as being too harsh, as in they can't watch it for an hour without experiencing "fatigue" that causes them to need to stop. Of course with a TV this sounds ridiculous we just want the most life like picture possible so these measurements are a great way to accomplish that.
With headphones though while something may sound more accurate it might not be enjoyable to listen to. It can be too harsh to our ears and cause listening fatigue. While the Sennheiser HD800 are a great pair of headphones I find them very difficult to listen to on a neutral amp for long periods of time. The only way I could really enjoy them was to get a warmer tube amp. In the end I replaced them with the Audeze LCD-3 which I would argue are less accurate headphones but are far more enjoyable.
In pomodoro if you get interrupted to the point where you need to stop what you are working on you are supposed to stop the timer and start over when you can.
It forces you to make sure interruptions are actually worth dealing with vs putting them off till after the timer is up.
Plex has a feature called Direct Stream that supports this use case:

I haven't used it but I did attend the talk on it at the AWS conference when it was announced.
It is not using DynamoDB under the covers. It basically uses a fork of MySQL for the front end and their own storage layer built from scratch on the backend. It does use concepts from the Dynamo white paper for redundantly storing the data to disk which removes the need for MySQL style replication. But it's not using the DynamoDB service currently offered from Amazon.
This would only make sense if when you moved bitcoins into coinbase they immediately converted them to USD. In that case, sure they would need to have USD on hand to cover your funds.
In the case where you are storing the bitcoins with coinbase and not converting it they just need to make sure they have the bitcoins on hand. Forcing coinbase to both hold bitcoin and USD to cover the value of those bitcoins makes no sense.
I'm sure he took it with an iPhone 6 cause that's the phone he has but it also looks like higher than usual ISO probably due to bad lighting.
The bigger issue is think about how close you would have to hold the watch up to your face to make it that big in real life. If you did that you'd be able to see the pixels but you wouldn't hold it that close.
http://www.hodinkee.com/blog/hodinkee-apple-watch-review has much better real life shots that mirror what I saw at the Apple store.
Now that it's in stores to try out (they have units on the table you can use the UI on in addition to the try on appointments) people should just go check it out for themselves.
I got the same sense from reading reviews, most seemed negative on it, like it was unfinished and not ready for primetime (wait till version 2 or 3 most would say).
I can tell you after going into the store and trying it out I left thinking it was a great product. The fit and finish is top notch and the UI is smooth and responsive. I couldn't test watch kit apps out so that might be an issue, but that'll be resolved once Apple releases a separate SDK for running on the watch which they said they would do later this year.
I'd say if you were previously worried by the reviews go check it out in person and you might be surprised.
It's kinda buried in all the announcements today but before this AWS Lambda could only be used for asynchronous calls. So if you were developing a mobile backend you could only process events asynchronously and had no way other than out of band push notifications to send data back to the client.
Now with Synchronous Invoke you can have a backend for a mobile app live fully on AWS Lambda. The benefit being you pay by the millisecond for compute time used vs having to keep EC2 nodes up and paying for underutilized instances.
I don't know the answer to this but given the user is the one who didn't complete the transaction in 10 minutes they are probably held responsible. I would guess if it was underpaid they would have to send more to the address (the same as if they only paid half the bill). If it's overpaid they probably send the overpaid amount back as a refund to the address it was sent from (or keep it).
To put this in perspective here is some napkin calculations on how much power dogecoin currently uses:
Assuming an average kh/watt of 2.333 [1] and the total network hashrate of 68 GH/s [2] we can see the network uses about 30 Megawatts of electricity. As a comparison Microsoft uses 250 Megawatts to power for their datacenters [3]. So it is wasteful, yes, but who's to say it's any worse than running datacenters so I can play battlefield 4 with my friends on xbox live which also provides no benefit for charity.
[1]: most ATI cards use this much per kh (https://litecoin.info/Mining_hardware_comparison), this ignores the newer ASIC hardware that is orders of magnitude more efficient

Considering the term goxxed is a staple of bitcoin vernacular I wonder why they decided to use it as their rebranding.
I'm not sure if people think crypto currency market manipulation is new but this was going on far before Dogecoin came out.

Lost in the news that they accept bitcoin is the "Coming Soon" under Butterfly Labs hardware mentioned on that landing page. First I've heard of a mainstream electronics store selling ASIC mining hardware.
Nobody GPU mines for bitcoin anymore (ASICs killed that long ago). My 2 year old ATI card makes $4/day mining litecoin or even $8/day mining dogecoin. If you want bitcoin you simply send the alt currency to an exchange and trade for bitcoin.
No they don't.
I wonder why this is. One of the benefits of bitcoin is that once you send it it's gone so there if you wait for enough confirmations there is no chance of charge back fraud. I'm not sure what they are worried about happening with international orders. Stolen bitcoin?
Except you can use any bitcoin wallet so they accept bitcoin not coinbase. As absurd as it sounds when snapCard (a site that orders from other sites for you) first started they would only work with Coinbase. Enough customers complained that they had to offer a second option to accept bitcoin payments from anywhere.
"If you believe the deflationary attribute of bitcoin will cause it to be hoarded instead of used as a tool of commerce"
I don't believe that, I think we can see that people are willing to sell it when there is something they want.
By the same logic why wouldn't you use all the extra cash you have to buy bitcoins? If you frame it that way then the answer is obvious, there is no guarantee the value will continue to rise so you will use it to purchase when you think it's over priced (I bought a TV and new camera when the price was over 1k).
The volatility actually ends up being a good thing in this regard because sometimes you are better off purchasing other goods with bitcoin, sometimes you are better off holding.
If the value eventually balances out and is truly deflationary against inflation then I don't think people are going to lose sleep over selling bitcoins that are going up 3% each year the same way they don't worry about taking money out of a savings account to buy something they don't really need.
If you've dealt with any of the bitcoin exchanges you'd realize Coinbase is the most reputable and trustworthy. It's either deal with them, trust Magic the Gathering Online Xchange or the Russian mobsters over at btc-e.com. Seriously this is a sector that is in desperate need of more legitimate players but so for this is the best we have.
Not all think that way at least:
