itsnotvalid··on Come and help save Posterous from oblivion
I am guessing that if Posterous and the ones who is responsible ultimately, should be giving the data to archive.org directly. This is the only sensible thing to do. Of course, they have to clear copyrights first.
itsnotvalid··on Stop Writing REST API Clients
When I see this post, the first thing to pop up is SOAP as well. Just that SOAP is not human-readable. Then I suddenly remembered that it wasn't SOAP itself that include the schema but the SOAP providers would generate WSDL alongside a SOAP endpoint.
itsnotvalid··on Show HN: Tavern, Next Generation Bulletin Boards/Forums (Product Idea)
Same here. I am not a native speaker of English and reading is not any easier. But as it's written using reveal.js you can reload the slides.

And when it comes to security, I think all the things listed there is almost like a requirement in current-day web development.

If somebody happens to have an invite of DesignerNews I'd like to give this a try, thanks!

itsnotvalid··on Why are there no true cross-platform filesystems?
Just a side-note, if he's not using Apple hardware to run OSX, there could be some licensing issues here.

itsnotvalid··on Hacker says security flaw let him access any Facebook profile
And since Homakov gave quite a detailed description of the class of bugs, it would be quite dangerous to use a browser with an active session to facebook now.
itsnotvalid··on Common JavaScript Gotchas
At the same time nobody else agrees on this language and currently only a branch of chromium supports the VM.

This is rather political - everyone want to have controls over the next language of the web, and nobody would want to adapt one made by others.

What even worse is that we all know it's almost impossible to create a good language without some dictatorship at the beginning.

itsnotvalid··on Announcing Xamarin 2.0
That pricing is much cheaper than a full $999 price tag and is entitled to $249 upgrades for future, so it seems to be a bargain.
itsnotvalid··on Announcing Xamarin 2.0
Then apparently the new pricing model is much more expensive to start with, since there is no longer discounts for renewals. Just to compare apples with apples, here is the difference in pricing:-

old: 999 first time and 599 for upgrades for "enterprise", 399 first and 249 for upgrades for "professional" and company with 10 or less people;

new: flat rate 999 for any companies (2+ people) and 299 (only for single person)

Sorry this may sound bitchy , I just don't like price-ups as I live in a location where inflation is killing me (and the salary is like half of what US rates are so software are twice as expensive in that thinking).

I am not against price ups and it's always better to be an early customer, but one a longer run, new customers (or existing customers as well if they don't get the upgrade price after the first renewal) is definitely paying more. That greatly affects small businesses because they can no longer use lower tier one just to get the juices with cross-platform joy on a more affordable rate.

itsnotvalid··on Announcing Xamarin 2.0
As much as the store page confused me, so you can't use the product after the end of your subscription (that is, the license is NOT perpetual)? I mean, would you be able to compile or release anything after the expiration of your current subscription?
itsnotvalid··on Dear Apple: I give up, WireframeApp will become open source
I guess you may try the news:yc way, open source it and sell it in App Store at the same time.
itsnotvalid··on Show HN: My first product. Thoughts?
It would be hard to evaluate as I know how to speak in Mandarin (and the hardest part comes to the written language, which again I can't evaluate.)

Not alone there are different favors of the written form.

itsnotvalid··on Diaspora Co-Founder Helps Startups Keep Kickstarter Backers Happy
I wonder if KickStarter would have been developing something similar already. If they do, the integration would be much smoother and would definitely hurt their business.
itsnotvalid··on Bootup.js - cache and load static files from local storage
Looks like an open-source version of Cloudflare's Rocket Loader, but without the source file concatenation. Still, we should produce something open-source for these.
itsnotvalid··on Hacking language learning
Any thoughts on non-spaced language such as Japanese (which I am learning) and Chinese (which I speak)?

itsnotvalid··on Problems with Skitch 2.0
I just regretted to upgrade the mac app store version of the app to 2.0. You know, the problem with app store is that you can't really use old versions of an app. The new version completely destroy the useability of snapping and destroy useability of sharing. Yes, they need tight integration with Evernote, however, Evernote really isn't my favorite for managing images (I use Flickr more) and they completely destroyed that too.

It's been too long that I saw such a degrade of functionality of updated apps for a very long time.

itsnotvalid··on Pocket Released (Formerly Read It Later)
What really made me sick is that the apps were charging (and silly me I paid for it) and now it turns into a completely free product. So, I am no longer a customer.
itsnotvalid··on Shutting down a product? Open source it.
For textmate there is 2.0 alpha actively updated: http://blog.macromates.com/2011/textmate-2-0-alpha/
itsnotvalid··on Shutting down a product? Open source it.
Technically they are just doing open sourcing for the most basic part. They are not starting a project, they are simply donating the code to those who want to start a project with it (read the post).

Being open-sourced doesn't prevent any codebase turning into some kind of abandonware. Certainly for me I have used a lot of software that turned out to be abandoned no matter they are open-sourced or not. But here is the problem, if it's a service, it's worse than abandoned. You simply can't use it. If it is just some desktop software, I can stick with an ancient version until I fill sick maintaining the running environment. For a service, that is it.

So to my own end, open-sourcing it, is at least, better than simply vaporize the service (which many of Google's services have been like that for the past months.)

itsnotvalid··on Linux Easy To Support = Lower Software Prices
I think a more justified way is to sell linux only licence on discount, and allow them to be upgraded to universal ones by topping up the cost.

Of course if that user operates on Linux, the likelihood of needing support at the first place would have already been lower...

itsnotvalid··on Why we are taking our startup to Hong Kong and other crazy stories of 2011
That is sad but true. Almost all my CS friends went to investment banks or private funds. I can only name a few that is willing to engage in startup-like activities. Fighting against the norm is hard here. (especially when the banks and funds pays pretty well)
itsnotvalid··on Stop writing good code; Start writing good software.
I think the problem of mess is that, if you have a team and they think so differently that they all don't like how others code.

Not to say, there are more than OOP on the world for programming. e.g. Hacker news is not written in some OOP environment and it is a piece of good software (IMHO).

I always remember this saying:

  // When I wrote this, only God and I understood what I was doing
  // Now, God only knows
itsnotvalid··on Graphene improves lithium-ion battery capacity and recharge rate by 10x
Or they can reduce the size of the batteries to cut weight.
itsnotvalid··on Graphene improves lithium-ion battery capacity and recharge rate by 10x
Since we can't control the discharging condition and rate most of the time, and today's design often stick the battery to a heat source.

Since I am no expert in chemistry, I rather point to an article here: http://batteryuniversity.com/learn/article/how_to_prolong_li...

Basically, the capacity degrades over charge/discharge cycles. The reason is pretty simple to explain, because you can't really operate the batteries in perfect condition, it always get worse while discharging and charging it.

The other conclusion of that report points to the fact that depth of discharge is related too. So instead of using it from 100% to 0% (actually 0% doesn't mean nothing left, it just means the phone can't operate on that voltage), recharge as soon as you have a plug.

itsnotvalid··on Google Music now available to everyone in the US
There is noticeable difference between 360p and 480p stream on Youtube already. They somehow managed to degrade that much for little bitrate difference.
