WebP is lossy. Google provides a gallery of images here: http://code.google.com/speed/webp/gallery.html

Basically, they are using predictive coding to achieve good lossy compression. However, I agree, I would also like to see double blind studies on the quality degradation.
I have to agree. Just about every bit of this article is correct, it's part why I hate developing for Facebook so, so much. For an API whose stated goal was to power the social fabric of the interwebs, Facebook is doing a terrible job of letting those of us who create the interwebs work with it. The only response I've gotten from FB engineers was either "Sorry." or "I don't know what your talking about," both in person at F8 or via IRC.
I Want My Converged IP
I am not positive myself, but I believe that Greenplum and/or Netteza are built on top of Postgres (highly customized) DB engines to ensure their transactional integrity across their clustered servers.
the chart looks to be a hang-over from google.com/finance; I like the interactivity of it... I'm sure they will replace it with a html5/canvas solution as soon as they feel the adoption is worth it (for those alternatives)
Is there an unofficial wiki for Facebook developers that is independent?
Disclaimer: I'm just speculating

Mike Arrington presumably wanted to reduce Jason Calacanis' stake because most of the revenue was coming from TC50 and AOL didn't want to buy them with Calacanis getting half the revenue. So Arrington, acting in his own self-interest as one would expect, sacrificed his business relationship with Calacanis in order to make TechCrunch more attractive for an acquirer. These diverging interests led to their fallout and understandably made Calacanis irate. Though, I suspect that Calacanis would have done the same thing if the situation was reversed.
You forgot microwaving them.
An actually helpful suggestion (I hope): help her change the settings on her camera. Explain that she'll be able to take more pictures without filling up the memory.
I've had similar issues with Ubuntu upgrades in the past. I went to Debian (stable) instead, figuring the longer upgrade cycles would mean fewer problems. That was all well and good until I needed to enable backports to upgrade Firefox to >=3.5 for work. Now the package manager's broken due to some weird dependency issues.

I don't understand why there is no free software equivalent of Apple, selling (laptop) hardware and maintaining a GNU/Linux distro that's guaranteed to work on it. Surely there's a buck or two to made?
This is one of the many things I love about Ireland. You don't have to drive very far outside Dublin, Cork or Galway to go back 50-100 years in time. These one-lane roads also make for good cycling too, if you go with a group who knows where they are going. :-)
I dont think it is about the technology at all. It is more about social factors. Enterprises often shy away from being on the leading edge of anything. There is very limited upside and big downside. I'm willing to bet that once the NoSQL space shakes down with some big winners, some defacto standards, enterprises will be adopting it just the same.

Enterprises also need to be sold to. I don't see any startup having a sales team pushing NoSQL solutions inside the enterprise (Amazon's SimpleDB and my own team's Windows Azure Tables might be exceptions).
Incidentally, a friend at Apple said they had a magician on campus today.
Parallel threads are still a myth in Ruby
They already have the basic. What they are terrified of is precisely that technological change and decentralisation has compromised their ability to do "non-basic" wiretapping, and want to roll back those gains.

Also, scrambling calls on the PSTN requires somewhat non-ubiquitous - if not necessarily any longer prohibitively expensive - acoustic coupling equipment. By comparison, PGP, VPNs, and TLS are much easier for an average person to use. To some extent, everyone uses these things whether they consciously sought to or not, at least in the case of TLS certainly.
Did the new functionality include reliable replication?

Lesson from a tech startup: Sometimes you need a human
Ask HN:  AOL Techcrunch acquisition more than meets the eye?
The majority of the feedback I am seeing on the AOL / Techcrunch deal is critical.

However, I'm seeing this as a massively good play for a 'dinosaur' that wants to get into the industry. Think about it- they now own an 'in' to cutting edge information on every major acquisition target.
Same for Bit.ly...
For the brave enough who wants to get better at reading, I can recommend (see Disclaimer below) Mortimer Adlers' "How to Read a Book" ( http://en.wikipedia.org/wiki/How_to_Read_a_Book ). In the book, he talks about how to read a book properly (in summary, as suggested in the article, read TOC first, take notes, become active etc.) and the books one should read from the Western culture. Britannica sells the compilation with the title "Great Books of the Western World". (I am not in US, so excuse me if this is just common knowledge there, and many houses in US are filled with this collection.)

Disclaimer: Unfortunately, although I liked the book, I have been unable to apply the methods he suggested, due basically to "leaning".
I thought it made sense... well as much as "stackoverflow" does.
They are claiming better compression at constant PSNR: http://code.google.com/speed/webp/docs/c_study.html
The problem with advice like this is that, as a result of following it, you become a phony. The "don't go back to being buddy buddy" stuff is just odd. It's manipulative at worst and unnatural and uncomfortable at best.

My philosophy is this: If you're half competent at choosing your team and someone you lead isn't performing, it's probably your fault. So before you decide that "your employees have made a mistake," you should probably be clear on whether not you made a mistake first.

Are the expectations clear? I bet you they're not. Leading people means exhaustive communication, especially about details and success conditions. If you're not sharing this stuff, you're not providing useful leadership.

Have you communicated the stakes? If something is important, don't assume that everyone else knows that. What makes it important? Why should anyone else case?

Are you available to help? If you're not making time to check in and support as unexpected complexities of the task crop up, you're in for some nice surprises at the end.

When people fail to meet the needs and expectations of the task, are you direct about it or do you pretend everything is cool? Do you look for opportunities to teach about the failing, explain what was disappointing? Most importantly, do you point out how to do better next time?

When people do outstandingly well, do you recognize that?

The tl;dr of this: getting what you want from people is a combination of being proactive and communicating. Not micromanaging, not being a babysitter, not being a bully, not being a softie.

Be direct, don't expect anyone to read your mind, understand you're part of the process as a leader.

(All this collected from being led by extraordinary leaders, lazy ones, and outright terrible ones.)
My gut feeling is they keep building because otherwise they go out of business. If they can open a development and slowly build a few houses (and get them sold) then they can continue to build out the development.

Based on those pictures and your comment, I would prefer that Florida re-issue licenses to contractors to continue building on sites that were half built before money ran out. This minimizes the continued over-development and keeps small communities from being stuck with a large HOA bill for the entire community when only 1/4 of the houses are sold.
They don't. And I'd still like to have one. I was just saying that the root of the problem is insecure services.
Very impressive.

The video perormance sucked for me until I toggled full screen display
Ugh. Google entering this pretty much wipes out the space - companies like bit.ly are going to need to work on seriously differentiating themselves from the pack, and even then I don't think they're long for the world.

I can honestly say I hope to never be in a market - or working on a product - where google suddenly decides to enter the game. Even if their offering sucks, or is broken, it sucks all the air out of the room because it's OMG Google.
I wonder what the web will be like in 10 years when most of these URL shorteners don't exist anymore and we're just left with a web full of links that go nowhere. I'm sure the Google one will survive, seems like we shouldn't have to use these URL shorteners at all though.
Last time I talked to the Street View people they mentioned that missing streets like yours are usually related to bad GPS reception at the time of capture, leading to the inability to match roads and imagery. This is usually the reason for small pockets of no coverage in otherwise densely-covered areas.
Should I require  username at login?
I'm putting together my first website, and I'm wondering if I should bother asking for a username at login. If the password is long enough, won't that be just as difficult to geuss randomly as a shorter username and password?<p>Assuming the answer to that is yes, it a good idea to force users to choose a password, or would that be inconvenient?
I'm really hoping for gift cards, not just as a user, but IMHO that's likely to stimulate a lot more spending in the Android app market.
Why do we need url shorteners again ?

When I see a shortened URL the probabilities of me clicking the link go down to almost zero.
Unit Testing Arduino With Python
He has pitched but been unsuccessful. The output from all of them is that we have to change our vision, sometimes dramatically, sometimes slightly. The problem is the vision is now "build something huge" instead of "get something out the door and iterate."

There was some interest, but the current pre-money valuation they've been talking about (~USD5m) is not enough to get anyone other than small angels involved, or we give away too much of the company.
http://upload.wikimedia.org/wikipedia/commons/5/51/JPEG_JFIF...

JPEG looks better to me. It's only a data point of 1, but it's the most important data point to me. ;)
Sure, if that's what you think. I don't have a problem with that. What I don't understand is why a personal 32-bit (or 128-bit) identifier is a human right. If it is, most of you, including the ones with static addresses, are getting shafted. Your address means less than you probably think it does.
I wasn't suggesting they would be used, I was suggesting they would be wasted.

Unless you want to run your new company as a process on my grandma's cellphone, that she can have more IP addresses on it than I can make a witty comparatory analogy about, is merely stupid and wasteful allocation.

The IPv6 address space may be so big we could never use it all, it's not so big we could never wastefully allocate it all.
I'm not sure I agree with the definitions of enterprise being implied in the comments here.

I'm at a giant company all of you have heard of and we have the sql server visual studio enterprisey people that the article mentions, and they fit the articles description to a T. I also work directly on analytics for our company, and good friend of mine does analytics for another giant corporation nearby that all of you have also heard of.

I believe our companies would be considered "enterprise", yet neither of us work at banks, neither of us work with ecommerce or supply chains for physical commodities, and neither of us are at tech companies. We both have groups heavily invested in sql, yet it is the wrong solution for both of us. Our enterprisey people had never heard of NOSQL or things like hadoop. Fortunately we're coming around and are starting to move things to hadoop, but the article matches my personal experience, and ACID is a requirement for the analytics we do. Our analytics are fuzzy by nature, yet we've been stuck in the sql enterprise mindset for years.
Given that the JPEG 2000 patents are licensed royalty-free, I think this says something about open source patent nitpicking.

"All patents that WG1 believes to be essential to practice JPEG 2000 Part 1 are available on ITU-T’s patent policy 2.1, which is fee-free (see the ITU-T web site for their interpretation of this)." http://www.jpeg.org/faq.phtml?action=show_answer&questio...
Well, it's the implementation detail. Right now, without a first class internet connection, you can't completely exercise your ability to communicate (and publish) freely. Likewise, I think that right now, without a public IP, you don't have a first class internet connection.

So, by the contraposition, the transitivity of the implication, and my mathematical powers, having a public IP should be treated as the fundamental right it enables.

Of course, if there are several efficient "implementation details" which enable the layer above, then you just need one of those.

I did not realize this would be so hard to find, I thought I may be looking in the wrong areas. That looks promising. Thanks very much.
Cool, thanks very much!
Really? I still know people that don't know how to delete files, because they're not in MS Word's File menu, after new, open, and save.
SQL is actually quite often a bad way to try to answer those questions, too! See http://philip.greenspun.com/wtr/data-warehousing.html for an entertaining explanation.

I believe MongoDB in particular can be a fairly good solution to build datawarehouses (I'm starting to use it for reporting systems).

One great point about MongoDB is that it makes the ETL process a lot easier (you don't have to prepare tables with the right schema and it supports large amounts of data).

I wouldn't be surprised to see some NoSQL solutions get wider adoption in the enterprise, either alone or with tools that build upon them.

As for the article: it's pure linkbait in my opinion!
Sure you can. While classic scams do appeal to greed, more modern ones appeal to altruism. They focus on advance fee scams, but there are plenty of fake charities and whatnot out there.

Thanks for the advice. My problem is usually being especially assertive, but a simple,"I will be prioritizing other things above participation in the company," definitely sets the right tone.

Google Wants to Kill the JPEG: Meet WebP
Great news, but long, long overdue (for example, it's been well over a year since Android launched in Canada).

The market is one of the weakest aspects of Android IMO, hopefully they'll add more features soon.
We don't need them. Companies that create the shorteners need them to collect information about who clicks on your links. That, and there's a service out there that limits updates to 140 characters.

Your public IP address is also not a first-class Internet connection. You think it is[1], because you have a crappy Internet connection. But if you were an established company trying to use the address for real connectivity, you'd quickly realize that your IP address is nothing more than a stamp your ISP is putting on a connection it's lending you. You cannot, for instance, advertise your /32 on two different networks through BGP. Other people can, because they have better, more meaningful addresses.

So this notion that we all have a fundamental right to full and fair access to the Internet is already subverted by the fact that we're all default-routed second class citizens of the Internet.

In an overlay network world --- a world that is easier for us to travel to than an all-IPv6 world --- this wouldn't be a problem. Addresses would be inherently portable, multihomed access (both through ISPs and through our friends and neighbors) would be the norm, the notion of "server" addresses and "home" addresses (where you can't take port 25 connections) would be extinct.

Unfortunately --- but very importantly --- this is not equally true of an all-IPv6 world. There is nothing magical that IPv6 does to give us all access to the BGP RIB's of top-tier providers. You're still going to be some ISP's b+tch whether your IP address is 32 bits long or 128 bits wrong.

I'm not arguing that people don't have this fundamental right you want them to[2]. I'm saying that the IP address doesn't actually give it to them. Static IP addresses are just something for geeks to argue about while the telcos continue locking down the Internet.

[1] I'm being presumptive because it simplifies the point I'm making; sorry.

[2] All though I don't think they in fact have that right; things that compromise the "right to IP addresses" are invariably first-world kinds of problems.
yes, you are right of course about the phone. But if the reason the phone isn't listed as one of the Android phones is because Google doesn't think the phone is good, then that is a slippery slope. What else do they think is inferior and will be (not just deprecated but) blacklisted from other search results? For Google to list their marketing material under what I would argue appears as search results is a mistake.
[edit - Nevermind, solved below in the comments.]
Does anyone know how these work long-term? This one shortens a URL to 4 characters, so for a potentially major URL shortener, there is a relatively low number of possible outputs.

Once they hit their limit, do they start erasing the oldest ones? The most inactive ones?

For shorteners that give consistent shortened URLs (i.e. everytime you shorten the same input URL, you get the same shortened output URL), how do they deal with hitting their maximum?
nice work. I subscribed to your blog. I'm probably a step behind you in the case of still rounding up and finalizing on 2-3 ideas and selecting one. I actually started trying to establish a sleep routine (sleep at 12:30 am, wake up at 7:30am drill) and deciding to put off B-school for another year.
you should assign them a password without a username. that would be cool cause nobody else does and really would be just as effective, except you need to assign it...they can't pick it!
I don't think anyone really believed that something you can hack together in twenty minutes, where your business plan is completely based on "for as long as Twitter doesn't do one", really counts as a "space". Anyone who invested in it deserved to get burned.

bit.ly were working on partnerships with publishers as their means of getting some monetization, but that's all I've really seen.

I'd prefer the Google one to the others, because at least I have some guarantee that the Google one won't go away.
Before I get to see the demo, I must look at two other screens.

The first has two photographs, one of an iPad running nothing in particular, and another of some people futzing around with iPads in a coffee shop. Do you sell iPads?

Also on the first page are a number of features of your product, but none of those tell me what the product is. Take the first phrase: mobile point of sale. Last I checked, "point of sale" was the way in which retail people refer to a cash register. So I when I see "mobile point of sale," I think "portable cash register." I have seen those in restaurants in Europe. The portable cash register is ready when I am -- I sure hope so.

Since I am going to "drive product sales with pictures and descriptions." But this is a cash register, no? Aren't those typically used in places where you can see the very product with your own eyes?

But then comes the confusion. Take orders from anywhere? Why would I want to take orders from, say, France while I have the cash register frob in my hands and I am talking to a customer? Ah wait, maybe you mean that I can take orders anywhere (as opposed to from anywhere) because, after all, I can be anywhere (modulo the cost of plane tickets and such) and carry your widget!

Then, I think some more, and I piece it together. Logically, what you are selling must be a device for traveling sales reps. Wherever the sales rep is is the point of sale, and thus the device is a point of sale device. And the sales rep carries a... catalog! An electronic catalog! I see.

So you're not selling a portable cash register at all.

The second screen, which shows up when I click the demo button, tells me that I can indeed view the demo, if I click another button.

And then comes the demo, which should have been first. Except when I try to do the demo, all I get is a countdown timer.

(I know the above sounds a little acerbic. I don't mean your idea is bad. It may very well be great. I am just trying to be up front about how you should not squander the eyeballs you attract to your site.)
Add the Dropbox File System to your iOS app in
I had the same question. Until last week when I sent out a link to a google spreadsheet, and my awesome </sarcasm> Navy Marine Corps Intranet Windows XP/Outlook 2007/Exchange system broke the link across two lines (but only after it was sent), and then every single recipient (about 100 physicians) said they couldn't see the document. I now use tinyurl.
I rarely use shorteners, so excuse my ignorance here, but what does Google offer here that bit.ly doesn't? Why would I switch to Google after using bit.ly for a long time?
I note that WinZip 14 does decode JPGs and reencode them smaller, but without further loss of quality:

"The main trick those three programs use is (partially) decode the image back to the DCT coefficients and recompress them with a much better algorithm then default Huffman coding." - http://www.maximumcompression.com/data/jpg.php
that's exactly right... agree with criticism and reassert what you want...

when i first started my own consulting company, i had read several books about assertiveness and that's the advice. agree with criticism and re-assert what you want. I was trying to collect a bill and the guy that controlled the money ripped into me saying i did a bad job, there had been bugs... I said "I agree, I think we all wish things had gone smoother, but I think the bill is fair and I expect to get paid." He cut me a check shortly afterwards. The guy was hoping for me to start defending my work and get into an argument. I really don't think I would have made it in business without reading that advice and following it. sometimes it's hard to swallow your pride, but when people are trying to manipulate you.. they play on that.

agree with criticism/reassert your position.
What historical evidence is there for this? In every case I can think of in which a Google product supplanted an established competitor, it's been pretty clear that it did so through merit. As a converse example, I don't see Google Finance establishing any obvious position of dominance. Google has had no lack of failed products.
I think he just wrote a blog post. He can apparently work under these conditions.
There are a couple such companies, I think. One is called Emperor Linux (if it's still in business) and offered reasonably late-model Vaio laptops among others.
