itsnotvalid··on SSL broken. (TLS 1.0 cryptographic attack that works. Not just fake certs.)
As mentioned in the article, the attack only works on TLS 1.0 (and below). Now the question would be, why are we still stuck with TLS 1.0 (at least with Mozilla's NSS) and not migrated to newer versions of the protocol,

I am guessing that they are able to bypass this restriction.
itsnotvalid··on Linode announces new datacenter location, Japan
It depends of what kind of business you are dealing with. If you mainly serves mainland, then host in mainland as you don't want sudden ban of your site.

However, please note that hosting a site in mainland requires a registration at the respective ICP bereau hosting province.

Thanks. isn't that seems to be a choice now for HK devs wanting a quality service for hosting?
itsnotvalid··on AeroFS (YC S10): It’s Like Dropbox, But It Runs Inside Your Firewall
One should note that Dropbox also transfer your files without the cloud if you happens to have those devices within the same private network.

Also, as much as I think, having some Java programs running at the background is the best idea. I have already got a Java background service running (Crashplan) and it holds up to 500MB after running a longer time. I have yet to receive an invite (msg me if you've got one!), however a native client/background service/daemon would always be welcomed.

There is an option too in the right-click menu for sharing a folder. They may just have missed it. But the same button on the web based interface is clear enough, I suppose.
itsnotvalid··on Check Out The New Blue Screen of Death in Windows 8
Seems people are rushing to use Virtual Machine software to test drive. However most of them don't have the correct hal.dll support...
itsnotvalid··on UTorrent.com compromised, malware added to installer
The current "mainline" one is simply the same as utorrent, with a different name.

Whatever the outcome would be, that is enough to stop people from using this piece of open source software to provide safer updates.
itsnotvalid··on Bitcasa: Infinite Storage (really?)
Clearly they need to work on a better video. The disrupt showcase was much more informational on those aspects. They mentioned caches, pricing, etc.
itsnotvalid··on Bitcasa: Infinite Storage (really?)
The finite part is the bandwidth you gonna get. If you can't get them uploaded, you ain't gonna get it filled.
itsnotvalid··on Bitcasa: Infinite Storage (really?)
My last time visit on mozy I didn't see "unlimited" offerings.
itsnotvalid··on Bitcasa: Infinite Storage (really?)
I guess somebody got it fixed for me, thanks.
itsnotvalid··on Bitcasa: Infinite Storage (really?)
We will see. Actually some backup companies also have such claims on storage (e.g. http://www.crashplan.com http://www.backblaze.com)

Well this is also backed by CrunchFund.... we would see (seen via TCDisrupt)

itsnotvalid··on Convergence, distributed, secure strategy replacing certificate authorities
This thing is as old as DEFCON 2011 (see http://blog.thoughtcrime.org/ssl-and-the-future-of-authentic...) but in view of current events of certificate trustworthiness, there is quite a chance for anything that can successfully replace the approach of trusting CAs.

Please view this blog entry (from the core author of convergence.io) to get the idea of also why DNSSEC is not a good approach (he had put it in the way that it's worse than CAs.)

itsnotvalid··on Michael Arrington Resigns From Techcrunch
Aren't we expecting this? Editorial independence is a good thing here, so really no surprise here.
itsnotvalid··on New Approaches To Designing Log-In Forms
as a matter of fact, they don't strictly tell you who the person is with an email address... they just tell you that the email address is taken.
itsnotvalid··on A letter from _why
Just remember that there are many ways to become successful. However without even trying, there is no way to learn anything.
itsnotvalid··on Large-scale Amazon EC2 Outage
one should build a crowdsourced status checker to really know what happens.
itsnotvalid··on Matz (creator of Ruby) joins Heroku
It is yet to see another cloud based solution for python. Of course, having Guido there is not the _real_ reason why this would happen.
itsnotvalid··on JS Plumb: cool js framework to build flowcharts, diagrams, ...
You didn't. Someone else did, so they post it again and again.
itsnotvalid··on Why You Might Want To Consider Java And/Or Clojure For Your Next Project
Scala seems to be a little better to work with in this case.

I think he is just referring to iOS. However I have to disagree the author that it's suitable for desktop GUI applications. I hate running Java programs on desktops (may be except Eclipse), as they always take much more resources than they actually needs, while still maintaining ugly interfaces all over different platforms, or would require much more work for the developers to solve issues with incompatibilities over different configurations of Java installs. For GUIs, Java is _still_ (for since Swing was available) not the choice.

why don't you submit the original than this reprint? (besides the comments on the new one)

itsnotvalid··on This is why memory fragmentation is bad
I have the inverse of your situation that chrome always use much more memory than firefox.
itsnotvalid··on The Go Programming Language, or: Why all C-like languages except one suck.
I thought the ideal language he was talking about is Haskell.
itsnotvalid··on Google App Engine team answering about New Pricing (ongoing FAQ)
Now it is much harder for people who haven't got any billing needs to try GAE seriously.

So people can only make testing app that doesn't cost anything or $9 for each paid app. Judging from the "tick" list (marketing props) there is not much you would get for $9 one.

itsnotvalid··on Reduce ajax requests to one-line with jquery-ahm
Any revision controlled source tree for this plugin?
itsnotvalid··on π = 3 (sometimes) for Nobel laureate
May be the word "fact" would be better to describe these kind of numbers.
itsnotvalid··on Meet news:yc, the open source Hacker News client for your iPhone.
Try wordpress for iPhone (http://ios.wordpress.org/development/) which has been developed for a long time. However I agree that it's easier to pick a project with less code in it to learn.

Another way is by writing an app.

itsnotvalid··on Firefox Add-ons with the Slowest Start-up
I think I have quite a lot of them (Firebug, greasemonkey, NoScript, Scarpbook, etc.) but the thing is, I don't close my browser every hour or so. Startup times are nothing if you don't do startups too often.

What would bother is any performance impacts with them running. However we don't have figures for that.
