Ask HN: Who is using Blu-Ray to back-up their data?
What is the best software and/or workflow to use to archive encrypted data across multiple Blu-Ray discs?

Any recommendations on brand of Blu-Ray disc to use and expected life-time of disc?

Any brand of (portable) Blu-Ray burner you would recommend?
> Anyway, definitely a lesson in where we choose to direct the benefit of the doubt. In this case, the author of the PR was the one who deserved it, but wasn't the one who received it.

"Benefit of the doubt" isn't such a finite resource. If anyone escalating this chain of tomfoolery had applied it, you would have likely found that there was more than enough to go around.
Yeah, I know it's basically like what happened after the industrial revolution. However, I wonder what the consequences would be, considering the constantly rising population.

-- Where do I fit in? --

We're looking for someone sharp to become the second member of our backend team, primarily in a DevOps role. Having a working knowledge of AWS, Chef, and Postgres is a must. Experience with Cassandra and Java on top of that is even better.

We're also looking for web developers fluent in Backbone (or similar) who is up to the task of spearheading our web efforts as well as UI/UX designers who can help to fill out ideas (Objective-C experience a definite plus here)

Beyond the technical specifics, if you're the type who is always learning something new and takes pride in their work, we want to talk to you.

-- What else should I know? --

We're based in DUMBO and would love to meet you! We're a diverse bunch. Members of the team have worked done everything from award-winning video game music to live visuals to open source game engines to being a professional chef.

We'd prefer local to NYC but would by no means discount someone remote with the right stuff. If this sounds interesting, please drop us a line. We'd love to meet and buy you a cup of coffee.

Its become fashionable to bash Facebook but comparing it to cigarettes is a bit extreme.

People need something to waste their time. Real life can get very bland at times. If Facebook didnt exist its not as if people would suddenly start self actualizing , writing novels and building companies. They'd probably be watching TV. We all need to turn our brains off for a few hours every day.

Till recently it was television and now its Facebook. But its way better as it is interactive and ties into the basic human need to gain the approval of others.

Those who profit are the ones who recognize these basic human needs and tap into them.

HN is the same thing but targeted at nerds. But the basic flow is the same. Its mindless and effortless , offering just enough novelty that you don't get bored.

People criticize things like Facebook and Farmville for being mindless and dull. But thats precisely why they're popular. Its an endless stream of slight novelty for very little effort. We need novelty and creating it ourselves can take too much effort. At the end of a long day our brains are just too tired.

Thats why we have Michael Bay Movies , Chick Lit and Twilight.

In the days before TV and electricity, alcohol and drugs may have been one of the ways to unwind and maybe in a weird way that validates OPs thesis.

I use Facebook mainly for the chat feature. Facebook turns acquaintances into friends and though some people dislike this ,for me its a big plus. It keeps me in touch with people who share common interests whom I wouldnt get to meet as often in real life.

Also Facebook is a gateway drug to participating in other online communities and realizing the power of people forming groups over the internet.

Bill Howe did a solid intro course for the University of Washington. Videos and other materials are available on Coursera.

https://www.coursera.org/course/datasci

The one thing I'd really change is to tighten up the range of tools used. It seems helpful to show students a range of tools, but it usually ends up being a major distraction for students and a lot of extra effort for course staff. Any such course is already going to be a blitz of new concepts and technology.

Go full Python, plus interactive tools as helpful (Weka, Tableu). Let them pick up R or D3.js or whatever later, after they have a better appreciation for the concepts and such which make them useful.
Thanks! Agreed, we need to tweak the difficulty.

> he uses his BTC stash as collateral

Doesn't collateral require that you provide the ability to transfer ownership?
If a receiver of bitcoins sells them for dollars right away, that isn't necessarily money laundering or tax avoidance. I don't know if you've tried to transfer money overseas lately, but banks tend to make it difficult and expensive. An international wire transfer is not a trivial thing to set up; in many cases it still involves faxes.

If bitcoin succeeds only as a payment network, where users convert from and to dollars at both ends, it can still provide a very valuable and legal service.
Probably not similar enough in style to e-mail messages but maybe. You would also need control sets.
The post assumes that Bitcoins will fail if they are not suitable as a store of value. It overlooks the fact that a currency can succeed as a medium of exchange, even if it is not suitable as a store of value.
That's only in the easy levels. If you advance to the harder levels you can almost never see the repo's name in the code.
> In such a future you wouldn't need to "cut the breaks" to "make it look like an accident" anymore, and doing it like this would be far easier, if strong security measures aren't considered from the start.

This future is already here to some extent. All they need to do now is to clean up the evidence (remove a plug, or have it self-destruct) after the event.

http://www.techradar.com/news/car-tech/delphi-s-new-plug-in-...

The OBD2 bus has been around in most vehicles since the late 80's and you can assume that those who need such functionality, have had it for a long time.
The biggest difference is the leisure time that accrues to you by retirement. On top of having more money saved, you're almost certainly in much better physical shape than someone who engaged in physically demanding activity for 8 hours a day, 40 hours a week, for 40 years.
Is what passes for a blog post? Copy-pasting 4 paragraphs out of a book?
Thanks! The front page only mentions Chef and Puppet, so fwiw this isn't clear at a glance.
I am a graduate student, currently working on building a x86_64 unix like preemptive kernel from scratch, as part of a course. Most of the OS dev guides and books focus on 32 bit arch and I haven't found a single guide so far that is based on 64 bit arch.
Since this this guide seems to be in its inception, I hope someone (hopefully me) will send a pull request for a 64 bit tutorial.

Building an OS has been in my bucket list for long and it has been one heck of an experience so far.

The Google search is only mentioned once in passing in the text, and in the image.

Their argument is based on the number of users/groups on lift. This is of course, also pretty flimsy - but I don't think its being presented as scientifically rigorous; just as an observation that many people are trying to give up Facebook (and apparently having some trouble).
Separate reply the HHS document (thanks for the link!).

400 bug fixes ~= 200 new bugs inserted? (Well, at least initially.)

Page 5, hardware upgrades: "Deployed 12 large, dedicated servers; upgraded storage unit", with a resulting ">3x Database Throughput"

Don't like reading that, although maybe it's not the critical path slowdown now. "upgraded storage unit" sounds like they're using a SAN, NAS, what have you, not the ideal recommended cluster architecture you described. I wonder if they've got enough IOPs....

Ah, reading this: http://online.wsj.com/news/articles/SB1000142405270230333290... confirms what we've been hearing about it running on VMs on machines shared with other Medicare services, vs. the dedicated hardware now.

System stability is bad at 95.1% exclusive of scheduled maintenance. Per this table https://en.wikipedia.org/wiki/High_availability#Percentage_c... that's a bit over 8 hours a week of unplanned downtime.

Hmmm, maybe not a total disaster now. And the fix-it czar said his highest priority was (correctly) to stop sending garbage to insurance companies. We'll see ... especially since they evidently haven't started working on the really hard problem of paying the companies....
I'm going to buy a bitcoin after the bubble has passed. What do we think the real price is. Like $10 or $100? What's the projected bottom? I'm hoping for less than $10, because cheaper is better. The thought that I would never be able to afford an entire bitcoin has a negative psychological effect, which may be silly.

What I like about alt-coins is how one can use that for games. Imagine making a game where a custom alt-coin, a bitcoin-fork coin that has no value outside of the game, used for transactions. Seems like a cool idea to me anyway.
Rinse ( http://www.rinse.com ) - San Francisco, CA Rinse is a very early-stage startup (we are only 4 people currently) looking to bring technology to the dry-cleaning industry. The industry is ripe for innovation! We're building mobile apps, tackling scheduling and dispatch problems, and scaling a service at over 10% week-on-week growth for months now.
I know 'app for laundry' is a tech cliché right now, but we're definitely encountering real demand. The problem is real, and we're solving it.

The team is very strong, with an HBS grad who grew up in a dry-cleaning family heading operations, and a Stanford GSB grad with direct consumer startup experience heading customer acquisition. I'm Stanford CS/EE, have built a few teams at various startups, and am just starting to build the technology and team to support this (very viable) business. The tech stack is Heroku / Python / Django / Celery / Phonegap / JQuery / Backbone / Twilio currently, but obviously there is plenty of opportunity to influence technology decisions early on, and plenty of opportunity to learn new technologies as well. We expect the next couple of hires to own entire new efforts, and have their hands in wide-ranging parts of our entire business.

We're looking for a Web Developer or Front-end Developer to develop interfaces for our customers, tools for our personnel, and visualizations for our managements. Ideally, this person would also have an active role in the design process as well, either leading design or working with our contract designer.

We're also looking for a Director of Marketing. Rinse is a quintessential B2C business, with plenty of opportunities for online advertising, offline collateral, partnerships, and 'growth hacking.' We're building a scalable business model and the technology to support it, now help us scale the business. Please see a job description at http://bit.ly/1dLJigo - The sky's the limit!

Finally, if anyone in San Francisco is looking to make a few extra dollars part-time, Rinse is hiring part-time Associates to help us deliver clothes. We pay $25 per hour for a handful of hours per week. Perhaps it would be a way for some of you bootstrapping startups to earn a little extra cash? To apply to the Driver / Associate position, fill out this web form: https://docs.google.com/a/rinse.com/forms/d/1kWZYu1kg1r8kxdD....

Hacker News has definitely been our most successful recruiting channel. Thank you! Feel free to contact me at sam@rinse.com with questions, comments, or applications.

You are correct. Usually I see this in CVs. It usually means that the person is proficient in C++ but knows a little C as well.
But C/C++ can be a language. It could be a code written in C++ but looks more like C than C++. Some people e.g. use character arrays instead of string class, avoid STL as much as possible, don't use object-oriented aspects of the language, etc. The end result uses some C++ libraries, compiles on a C++ compiler but resembles C more than anything. I think it would be appropriate to call it C/C++.
Very unlikely. Much more likely explanation is that Satoshi was influenced by him and uses similar terms. AFAIK Szabo is a lawyer / historian.
He knows; he's pointing out that you can go to Latin High Mass / Tridentine Mass in certain parishes in big cities. There's a bunch of places in Chicago that do it once a week too.
Once I was a Marine combat engineer. We worked all day. Reveille starts at 06 and taps wasn't until 20, 21, or maybe even 24. There was a singular focus throughout the day: get shit done.

That involved no computers, no phones, no digital distractions. Just blowing up stuff, building bridges, or moving boulders by hand.

Physically draining work that at the end you try to somehow find a can of un-skunked beer to cheer to.

I remember the culture was unkind to office work, they saw it as soft. That's partly why they were out there in the first place, unfit for mainstream society, not wanting to be desk jockeys, just good ol' boys, the desperate, the unwanted, the jailed, standing around in uniforms doing things with their hands. I made sure I never told anyone I was any good with computers.

The type of problem solving we had to do on a day to day basis didn't require too much thought, and if anything there were always policy or documentation to explain what to do and how to do it.

Long days, hard work, but I never had to use my brain. I quite enjoyed functioning as a tiny cog in a big machine despite the risks.

Transitioning home, I found work at a premier tech company, one where they make phones, tablets, and computers. The work was different. I stared at screens all day. Inside a cubicle with fuzzy walls, where often times the only communication I have were email chains.

Operating a computer, functioning as a tiny switch in a big board required the a more precious asset: my brain. I was thinking all the time, trying to recall, connect, and communicate. And doing the same thing all day is... boring.

I went home every night drained. Physically, mentally, and emotionally. The days weren't as long, the environment wasn't bad, the risk were low but the work is hard. I hated it.

Nowadays I code. I romanticize my job by equating it to writing love poems to an inanimate object. Sometimes I get affection, often times I get rejection. It's an ongoing love-hate relationship. One that just takes and takes from my brain while leaving me a soft, mushy lump on a nice Aeron chair yearning to be free.

Computers took a lot from me since I was 10. Two decades late I've only barely learned how to take a lot from computers.

Find your balance.

Largest source of inefficiency (and heat) in common isolated SMPS designs is output rectification, which has to run on frequencies ranging from tens kHz to units of MHz, thus the diodes there tend to spend relatively large proportion of operating time in various half-open-half-closed states. Active rectifiers somewhat improves overall efficiency for high output currents, but the problem with switching time still remains.

On the other hand for line-frequency rectifier times required for rectifier to switch can be ignored and only significant source of heat is voltage drop on rectification diodes (ie. 0.6 - 1.5V), so one watt of heat dissipation per one ampere of current is good ballpark.
He means insurance prices will rise for those who choose to remain self-drivers. However, you bring up a good point, incidentally, that even if the insurance costs more for a self-driver versus auto-pilot, rates will go down for _both_ either way due to much safer roads.

Why you should Not upgrade kernel on elementary OS Luna/Ubuntu 12.04.
No article link on me, but my guess the cause is that there, with bitcoin having doubled a few times in a few weeks to new highs, are more people who feel it's overbought and want to cash out / lock in enormous gains that could briskly vanish / sell short than there are people who feel the opposite. Basically.
