Nike Air Pegasus 2 are the best running shoes I've ever had for training, I went through a gait and foot impact test at a sport science clinic to match shoes to my running style. Their combat compression kit is also some of the best you can buy in terms of lasting the year even when used every day.

Now if you meant those ridiculous Airs with the spring shocks in them then yes, but brands that endure aren't built on nothing.
More important than the speed of those backups is this:

And that makes me think of Anathem and the potential issues around long-term data storage that is capable of surviving through falls of civilisations and/or sacks of storage areas.
You can keep your recent backups in a fast access location for disaster recovery. It would be a good place to keep older backups though that you don't need to access in an emergency.
>Do you want to scan dmesg to see which serial port your USB AVR programmer has appeared as?

If I only have to do it once it's no biggie. Do you want to have to rummage around in /dev to see which new name your DVD writer has been given today? I suspect that specific udev bug has been fixed by now, but I still don't feel confident that I can reboot a linux system and have my device nodes be the same ones they were before, even though I haven't plugged anything new into the USB ports since 2009.

>Do you really want to edit /etc/fstab to mount a flash drive?

I should've been clearer; if you set it to allow user-level mounting then FreeBSD will let one simply use the regular "mount" command with its ordinary arguments to mount a flash drive. No need for a new command with a new name.
Most companies don't trade at book value because net asset value is a bad measure of market value. Getting a mark-to-market assessment on a firm's entire balance sheet is very expensive and still resorts to estimating market value rather than directly sampling it.

One could do equity value + discounted payouts - discounted invested capital. This includes payments on debt and possibly taxes.

This measure would not be a "value" in an economic sense as valuation is in present terms, incorporating future potential and using the past only to inform assumptions. This measure catalogs a company's time-integrated capital productivity. This could inform a valuation, but taking an extreme case, it would value dearly a shell company that just paid its assets out in a dividend.

With the subjectivity complexities like cross-border activity or M&A introduce the exercise has little value beyond the pedagogical.

Richard Stallman: We're heading for a total disaster
The ideal solution is the Quadfecta (is that a word?) - Dropbox for (in my experience) excellent versioning/synchronizing (Never failed me) + Backblaze (or its ilk) for continuous Offline backups + Super Duper (weekly/whenever) - for Image Backups - + Something (Arq?) on top of Glacier for long time off-site-archival.

For $50 in software (Arq+SuperDuper), $100 for an external HD, and less than $25/month ($4-backblaze, $10 Dropbox, $10 Glacier) you have a backup system that is next to air tight for a Terabyte of Data and a working set (on dropbox) of 100 Gigabytes.

Unfortunately, SVG hasn’t been well supported on Android until quite recently, and likewise for IE.

Also, you still have the problem that SVG doesn’t support hinting, so for small icons its value is limited.
Hypothetical question - say I'm an idiot and I already have a database full of md5-hashed passwords. What do I do now?

The best I've been able to come up with is bcrypting the md5's. But unfortunately, while bcrypt^-1(ALL STRINGS) is hard to compute, it's not clear that bcrypt^-1(range(md5)) is. I see no compelling reason why it wouldn't be, but I don't know enough about the subject to offer a strong claim.

Can any experts offer advice on this?

(I'd also replace the `bcrypt . md5` password with a regular bcrypt one after the user authenticates.)

Ask PG: What made you change your mind about crowdfunding?
Paul,

Four months ago, in a thread about crowdfunding (http://news.ycombinator.com/item?id=3893783) you said that "having a very large number of inexperienced investors is the worst scenario possible."

FundersClub is a YCS12 company, so I´m curious: what made you change your mind? The whole scenario? A different approach if an entity works like a proxy? Is there any secret sauce you can share?
This is by far the most important comment on the page. Very frustrating that, when I read it, it was nowhere near the top.
The fundamental flaw in CatB is that it was essentially an adaptation of ESR's libertarian creed, that Free Market is infallible and would always boil down to the best optimal solution. While that may work on the scale of a single project, it fails when applied to a full ecosystem, and thus we get dozens of competing projects aiming at the solving the same problems (WMs, desktops...).

It also postulated that code being open would incite devs to be as their technical best, in order to gain peer respect. That didn't happen either, quite the contrary the OSS community has proved to be rather conservative and traditional, Unix being seen as "The Right Way", not to be deviated from.

In short, the Bazaar model completely failed in its promise to always let the best solution win. What we got instead was perpetual chaos, and less than 1% of the desktop share.

I attended the 1st GUADEC back in 2000. If at that time we had known where we'd actually be 12 years later, we'd all have left in disgust.

I moved to OS X in 2008, my only regret was not doing it any sooner.
WikiLeaks stories are upvoted around here because (I suspect) they reflect the massive social changes that the internet is enabling, which the HN community is clearly interested in.

Anonymous, WikiLeaks, et al represent the changing power dynamic in society globally, and that's fascinating to a lot of us (especially considering it generally involves people with a hacker mindset).

I'd agree with flagging a real political story (like a Dems v Republicans rant) but flagging a WikiLeaks story doesn't make sense.
The problem that I've seen with lockouts is that they become a route for denial of service attacks.

If lists of usernames/emails are available elsewhere for users of the site - a NastyPerson can reasonably quickly lock your entire user base out of the system (either deliberately, or by a poorly coded password attacking bot).

If you have per-IP lockouts then you're still open to bot-nets and the problem doesn't get much better.

What seems to work best is to slow logins down rather than lock them out completely. Still lets users in, but slows down bulk attacks enough so that the risk is low.

And having nice metrics / reporting tools so that you can spot attacks as they're happening and make appropriate case-by-case responses.
They should provide a "time capsule" option - pay X dollars, and after a set number of years, your data archive will be opened to the public for a given amount of time.

There'd be no better way to ensure that information would eventually be made public.

It’s not usually the high-dpi devices that you’d be adding hints for. The point is that anything that is going to replace today’s pixel-perfect bitmap graphics still has to look pixel-perfect when rendered on lower-dpi devices, which is going to remain by far the majority of visitors to most sites for a while yet.
Nerve-growth protein in semen linked to ovulation
This is sort of OT, but I always love to share this little tidbit of my time at Xavier (I graduated in 2001). At the end of the semester, the bookstore would put out these huge boxes and when they would refuse to buy back people's books (because the same book was not being used the following semester), people would just chuck their books in the boxes. I'm sure the bookstore was just selling those books to some other efollett (or whatever) bookstore. I used to go and snatch tons of books out of those boxes and sell them on half.com or amazon marketplace...similarly, profs would put the sample textbooks outside their office doors for people to take if they wanted them...those went on half.com and amazon marketplace too...I at least took a bite out of my textbook expenses that way.

I always remember reading in a book once (Influence by Cialdini?) that the main signifier for whether a doctor gets sued or not is not whether they make mistakes, but how they handle them. 'fessing up honestly is the way to go.
I have said it before and I will say it again:

A police state is simply a free society where only the police can see the tapes.

We need laws, now, that provide for all forms of surveillance and tracking of humans in public and semi-public locations to be made known, and the (raw) output of the surveillance to be published in real- or reasonable- time.

Only in cases of valid, warrant-backed surveillance should this not apply.

It does not matter that the surveillance is pico-second lasers, big CCTV cameras, GPS phones or whatever else. Make the laws cavier surveillance, tracking and monitoring. Not specific technologies.

After that, of course, hiding your affairs from your wife will become, quite literally, your affair.
Is there anyone else that thinks Harvard is now spewing out "bozos" for writing this type of piece? Are you that arrogant? First of all "B class" employees are generally speaking still highly intelligent and educated. Second off, you seem to dismiss the reality of the business world in replacement for technical achievement.

To me all this article displayed is the clear distinction between the technical and the business side (that which employs the technical).

Degrading "B class" people as "Bozos" is quite frankly disgusting. You can have all the brightest minds in the world that create the next progression of technology, but without the "bozos", they will be stuck in a room congratulating themselves into perpetuity...
per object. So although the chance of losing any particular object is tiny, the chance of you losing something is proportional† to the number of objects. Still extremely small.

†roughly proportional if you have << 1e11 objects
Add a new bcrypted password column.

Alter authentication so that it uses bcrypt column if populated.

Alter registration/password changes so that it populates bcrypt by default.

As old users log in (and you therefore have access to their plain text password and know that it's valid) populate the bcrypt with the correct hash.

After a period of N weeks when you've basically migrated all of your active users, do a forced password reset on the rest.

Kill the MD5 column.

Done :)
Great idea.

Entrepreneurship: Silicon Valley vs. Munich
"No offense, but this post doesn't quite match what you wrote originally. My sigh was in response to the phrase "Dropbox should work here, ...". You didn't state security as your concern as to why not use Dropbox, rather it was cost. This might lead someone who only needs <2GB backed up to believe that Dropbox is perfectly fine for that task."

A fair point.

In my case, Dropbox use is in addition to local RAID (scratch) NAS (network scratch, access of larger files) + off-site (backup).

I only use Dropbox for syncing and sharing.

The sync vs backup is an interesting one, simply because most consumers couldn't tell you the difference.

For example: Q: "Are your contacts backed up?". A: "Yes, they're sync'd to Google".

I did conflate my scenario with thinking about my girlfriend's peers in my post. And then reacted from my perspective again... my bad.

"Agreed. IMO no consumer backup system is quite there yet. TimeMachine is very close, if only it would do better logging and have some more intelligence about warning messages"

Vigorous agreement here too, except for the TimeMachine bit as that is Mac only and doesn't work for <insert any other system or device that isn't Apple Mac OSX).
This is so confusing. So apparently if you spend the entire month retrieving the data at 1.6MB/s it only costs $40 plus transfer fees? And more importantly, how do you throttle your retrieval?

Edit: So I'm working through a scenario in my head and trying to figure out how charging based on the peak hour isn't completely ridiculous.

I have 8GB stored to try out the system. This costs a whopping dollar per year. One day I decide to test out the restore feature. So I go tell Amazon to get my files and wait a few hours. When Amazon is ready, I hit download. I'm on a relatively fast cable connection so the download finishes in an hour. I look at the data transfer prices and expect to be charged one dollar.

But I didn't take into account this 'peak hour' method. I just used roughly 8GB/hour over the minimal free retrieval. This gets multiplied out times 24 hours and 30 days to cost 8 * 720 * $0.01 = $57. Fifty-seven times my annual budget because I downloaded my data too quickly after waiting hours for Amazon to get ready.
Surely if the journalist actually thought Apple stock would increase in value 6 fold in the next 8 years they'd buy it. (And then put a disclaimer on the article.) If the market shared their opinion then it wouldn't be available to buy at such a low price.

If you don't need to support legacy browsers, then you can use 2.x.

If you still need legacy browser support, then use 1.x.
In certain segments: yes. If you're doing something aimed at developers or gamers, supporting IE (any version) isn't all that necessary.

A battery could presumably power it long after being unplugged.

Coincidentally this research was from 1958, so I assume there is a connection there. Thanks for posting that - It puts thing into perspective.

We just ran a quick cost forecast and it's interesting:
If you start with 100GB then add 10GB/month, it would cost $102.60 after 3 years on AWS Glacier vs $1,282.50 on AWS S3!
Also remember its free to recover your entire Crashplan archive (I have 500GB with them). If you wanted to recover 500GB with Glacier it would cost $200 @10MB/s (according to someones calculation further down) You have to pay for retrieval
I pressed Cmd-S instead of Cmd-D...
Maybe not everybody, but it’s a reasonable default. IE8 has been out for more than three years, and works on Windows versions as far back as XP, which in turn has been out for more than a decade and is nearing the end of support from Microsoft.

There is accommodating customers, usually large organisations, who for whatever reason have chosen stability in their system software. And then there is not taking advantage of new technologies that almost everyone in most markets can use, and that almost everyone else could upgrade to if they needed to, just to support a tiny and shrinking minority.
I'm not sure if cost is right. Each project I work on is approx. 50-60 TB in size (video). Recent one got backed up on 20 LTO 5 tapes times three. That's $600 for tapes per project. Each tape set went to a separate location - two secure ones for about $20/year and one at studio archive for immediate access, if needed. I find this method extremely reliable and it cost ~$700 initially to back all up and virtually non existent further fees. With Glacier it would cost $600 per month.
While it's not as comprehensive as full traffic redirection, I host a shellinabox[1] over HTTPS on my server that I use when SSH is disabled. It's quite convenient when I want a shell from anywhere quickly since there's nothing to setup.

I also have an openvpn for when I want full tunneling, but that takes more time to setup properly.

I think having the last letter visible for a very short time is a good balance. I certainly do not want the password to be visible in clear text. Shoulder surfing is an even bigger issue for mobile devices like phones or tablets -- which you routinely use in public and around strangers -- than it is for laptops or desktops.
Enterprise-class Code: how your environment can dictate your coding
I also connect a lot through an EC2 machine that I use as a proxy. I do this because I do not live in the U.S. and many websites require U.S.-based IPs.

It's a pity that StackOverflow doesn't allow me to do this (so I end up turning the proxy on and off and back on again). It's not like you couldn't rent a cheap Linode instance (or from another provider, take your pick) and do whatever you want with SO, if you really wanted to.

SO needs more sophisticated tools to block the access for bots/crawlers. IP blocking just doesn't cut it and tends to discriminate against legitimate users with special needs.
> Governments of stable countries are obviously capable of this

I don't consider that obvious. I live in Berlin, the capital of what most would consider a stable country, but my apartment (which is even older) has been a part of 5 different countries in the last 100 years (German Empire, Weinmar Republic, Nazi Germany, East Germany and finally, the Federal Republic of Germany).

Not really. Facebook and other social sites nowadays all rely on one true personal identity. On forums on the other hand you can be whatever, multiple times, and have a discussion with yourself (even a meaningful one).
I wonder why that site is using the v1.0.1 version of it's own code.

Was v2.0.1 not suitable for that simple landing page?
I don't know what the best practices are, but some crackers definitely do do that. And yes, the added processing is generally too large for non-cracking applications.
Whenever I read about "Unlimited" plans (Backblaze has it as well, for $3.96 if you get a 1 year plan) I always think of things like Joyent and their "Lifetime" hosting, or AT&T and their "Unlimited" data plans. Their business plan is usually structured around people not actually using the service, and those who do use the "Unlimited" option usually end up either (A) being rate limited, or (B) having a conversation with the hosting/data provider to encourage them to transition elsewhere.

What's exciting about this, is that Amazon doesn't care _how_ much data you send them - presumably they've priced this so it's profitable at any level you wish to use. It's a sustainable model. Services like TarSnap/Arq will likely adopt this new service (Possibly offering tiered backup/archival services?).

I have (close to) zero doubt that Amazon's Glacier Archival Storage will be available 5 years from now at (probably less than) $0.01/Gigabyte/Month. They are a (reasonably) safe archival choice. Now that light users (<300 Gigabytes) have a financial incentive to move off of CrashPlan onto Amazon - it further exacerbates the challenges that "Unlimited" backup providers will face. All their least costly/most profitable may leave (or, at the very least, the new ones may chose Amazon first)

With that said - I love Backblaze (Been a user since 2008) for working data backups, rapid-online (free) restores - and I will continue to use them, but I wouldn't plan on archiving a Terabyte of Data to them for the next 20 years.
As I said: "I'd also replace the `bcrypt . md5` password with a regular bcrypt one after the user authenticates."

The question is what to do to protect passwords starting today?
