There is no nVidia chip in the Surface Pro 4. I believe you are thinking of the Surface Book.

I completely disagree with this article. Yes, helmets may increase the risk of other injuries (not inclusive of "I am hearing a helmet, I am a invincible" injuries), but the benefit of reduced head injury vastly outweigh the increase in other injuries.

On another note, there has been quite a bit of development into helmets in the last 5 or so years. Check out MIPS system [1]. It basically allows the head to move independently of the helmet increasing the "time" of the impact and also reducing oblique forces on the brain. Does it 100% work? Who knows. Is my head priceless, yes.

The greatest share of accidents are because of infrastructure, so put all your effort into getting better road for foot and cycle traffic, it's more effective to prevent accidents than injuries.

I've never hurt my head while on a bike, yet the first thing you hear when I've been in a crash is: "Did you have a helmet?". Statistically helmets help in rare but severe cases, compared to a seat belts and airbags that helps against almost all injuries in cars from mild to serious..


Already has a thread going on HN (and was currently at spot #1):

Always impressed by the write-ups the Backblaze team does. Very informative and very clear on what you guy are achieving and how you do it.

Crazy amount of hardware involved, and Backblaze is the "small kid on the block" in relation to FB, Google, and Amazon.


Yev from Backblaze here -> Yea, we hope they start doing more stuff like this too! More information = everyone wins!


Great theme, I do enjoy it. A few suggestion:

- make the bad bar thinner: it takes up a good chunk of usable screen real estate for just showing file names (especially important on laptops)

- The scroll bars could be a bit "lighter". They blend into the dark a bit too well.


This can be customized, thankfully. I love this theme now! https://github.com/YabataDesign/afterglow-theme#tab-height-s...


Did you mean the tab bar? It's specifically mentioned that you can change this with a setting.


Try:

    "tabs_small": true
for small tabs. I just turned it on and now it takes up about as much space as space grey did.


I find Sourcetree to be a pretty great product, with some negative marks here and there. I use it on W7 and OSX and find the "tabbed" interface of Windows versus the separate windows of OSX much easier to work with, especially on large products.

Some issues I have: - The app does have some lag at times. I really wish the app would update with local changes and remote changes much faster. Commits can also take some time. - I know how to use the application, but it could really use some better explanation/help around some features. For example, how to set up SSH keys and how branch/merge/stash/tag work. This would make Sourcetree much easier to learn for new users.


Thoughts on using this as a cache instead of memcache or redis? Yes, it does not have nearly as many features or functions but when raw performance is needed I could see this working (given an api for using this via Node.JS, PHP, etc.).


You'd be better off using MemcacheDB/LMDB http://symas.com/mdb/memcache/


You seem to have written a great piece of software that you're very proud. I don't understand the ownership very well, but if you're allowed, why don't you promote your database with its own site, like every little javascript library out there?

Good examples: http://duktape.org/ (it might seem silly but that right column makes people want to try it!), http://redis.io (i bet this page wins many folks http://redis.io/topics/twitter-clone)


why even pay the cost of memory mapping if its a transient embedded cache not shared between servers?

just use a std::unordered_map, or better yet a tbb::concurrent_unordered_map or whatever the equivalent is for your language


Because it's shared between processes on the same server.


In theory STL implementations, if used with a custom allocator, should be able to pull this off... that's why the STL containers all have internal 'pointer' typedefs.

Practically speaking, Boost.Interprocess includes a shared memory hash table implementation. Boost Multi Index, which is a further generalisation of containers to allow the construction of database-like indexes, is also Interprocess compatible.

http://www.boost.org/doc/libs/1_57_0/doc/html/interprocess/a...


Because it will persist between restarts?


then it seems strange to call it a cache.


It could be a cache to a much slower backend. I pull a lot of stock price and other data to my server which is is slow - 200-1000ms per series. I cache it in postgres which allows me to load it nearly instantaneously. It also allows me access to data while I'm disconnected.

Another reason to cache to disk is that you want to store more data than you have ram.



The author is an OpenBSD developer talking about crypt(3) which supports bcrypt hashes: http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man3/...

OpenBSD implemented bcrypt more than 17 years ago http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libc/crypt/...


Could you elaborate on that? The article explicitly mentions bcrypt, so what's the point you are trying to make?


I would guess he was trying to mock the meme that everyone says whenever the question of storing passwords comes up here.


Amazing how little this was publicized and promoted compared to Baumgartners jump. Undoubtedly because Redbull used FB's jump for marketing, but still a feet like this should have had more media exposure.

On a side note: If the marketing/publicity budget on this was so much lower, and the design was simpler, how much less do you think this cost compared to FB/Redbull Stratos?


I believe from reading the article that he planned this in secrecy and the lack of publicity is intentional.


Yeah, according to this it would seem like it

> Mr. Eustace said Google had been willing to help with the project but he declined company support, worried that his jump would become a marketing event.

Seems like he did it just because he wanted to do it... And that's awesome.


It's great to be able to afford that...


If something went wrong and he died that could be bad for stocks. Better keep it a secret until it's a proven success.


Imagine how much he could have got in sponsorship money from Monster Drinks or some other competitor of Red Bull.


Alan has been with Google for a long time, he doesn't need money. Having interacted with him on a number of occasions, this whole think shocks me. He doesn't come off as the extreme type. Always seemed more Mr Rogersish. Awesome huy to work with and for. Very impressed.


Because Alan didn't break the world record. According to article, he used drogue-chute, which is basically a small parachute, and it's WAY safer to jump with drogue. Baumgartner, however, didn't use no drogue-chute, and has really broken the world record. Funny that during Baumgartner's jump they kept telling that previous record was held by Joseph Kittinger, while it did not: FAI doesn't recognize it, because with drogue chute it's way easier and safer.


http://www.fai.org/records/news-of-records/37017-baumgartner... Here is the list of records set by Baumgartner. The record set today is the highest exit altitude. So yes the record is broken. Baumgartner will still have the farthest freefall and highest speed jump without a drogue. The article did not say all records broken. The most important record to the public probably is the exit altitude record.


So what's the current record with a drogue chute?

And are you sure the drogue was used during the entirety of Alan's jump? It mentioned that he did a series of backflips and broke the sound barrier during his jump. Is that even possible w/ a drogue?

EDIT: Plus, you seem to harbor some negativity about his achievements. Two things (1) It was verified by the US Parachute Assn, and (2) perhaps this reaction is precisely why Alan didn't seek press fanfare; it's an awesome accomplishment by itself!


sniff I smell an Austrian!


This is an eerily similar project to something posted a few weeks ago here. Most notably, the exact same "success" animation.

Third line on the link:

   This is just a clone for Bootstrap of the original SweetAlert.


Wow...my eyes must be going.


It's a fork of the repo you mentioned, but with Bootstrap.
