"Flash is still the best way to make video content accessible to the largest number of users"

Choosing any one option is rarely the best way to do anything. Offer whatever users need. In the early days of Internet video it was not uncommon to see 3 or 4 different video types available for download. This was in an era of considerably slower computers to do the encoding on the backend and expensive commercial video encoding software. It's not that hard to just offer FLV, straight H264 and even Theora. For other common uses of Flash offering alternatives may be a bit harder but not out of the question. If you have interactive data presented via Flash just give non-Flashers a boring ole' table of the same data. If you build games in Flash Adobe is going to give you the option to publish onto the iPhone and get into the App Store. If you are serving up Flash ads just serve a static image file instead when there's no-Flash -- many sites are already doing this today.
That first paragraph really reads like an advertisement.

I'm not saying you got any personal gain from writing that, and I might just be crazy, but it really sounds like some celebrity in a commercial would awkwardly read off of a teleprompter when sponsoring a product he's never actually used.

Alex Gaynor - Thoughts on HipHop PHP
The line about "Most users not commenting" sounds like damage control; it's true about almost every website in the world. My old rule of thumb was 100 visitors for a comment.

As for the Pro/Anti apple site; I have a MacBook pro sitting right next to me, but covering the code-name for the next generation iPhone (http://www.engadget.com/2010/02/02/next-iphone-codename-new-... - K48 for those wondering) in anything more than a twit feels inane to me.

I've been using homebrew for a few months now and while I love it I still can't figure out how to 'brew remove' packages that have more than one version installed.

For example:

I've looked at the (very sparse) 'brew help' and the wiki and still haven't found a solution other than manually deleting the extra version directories.

Am I missing something obvious?

We've been putting on the finishing touches since the weekend. At the moment, we've been running through the startup experience over and over, clearing any rough bits that are low-hanging fruit.

We've been working on the new bundler, which makes the normal unbundled experience as safe and isolated using system gems (the "default" experience) as when you explicitly lock the dependencies. We cleared a bunch of small bugs today and are coming in for a landing.

`instance_eval` and `class_eval` are very hairy if you pass strings (which you MUST do for some kinds of template metaprogramming). But they aren't hairy at all if you pass blocks, where all you are doing is (essentially) setting `this`.
"... The liquid glass spray produces a water-resistant coating only around 100 nanometers (15-30 molecules) thick. On this nanoscale the glass is highly flexible and breathable. The coating is environmentally harmless and non-toxic, and easy to clean using only water or a simple wipe with a damp cloth. It repels bacteria, water and dirt, and resists heat, UV light and even acids. ... Liquid glass spray is perhaps the most important nanotechnology product to emerge to date. It will be available in DIY stores in Britain soon ..."

Not news but a PR release. It pays to be cautious when making claims to be "new", "harmless" and "available in stores soon". The claim the particles are 100 nanometers is significant.

Why?

Well it appears that a lot of research is done on nanometer particles, health and lung function and the threshold for damage around 100 nanometers ~ http://www.google.com/search?q=100+nanometer+particles+and+l... even more for 50nm. Below a certain size, particles are membrane permeable - when breathed in, pass directly through the air/blood membranes of the lung into the bloodstream. There is a lot of research to suggest that sub .25µm particles of diesel (2.5 micrometers = 2500 nanometers) causes health problems ~ http://www.google.com/search?q=.25+micron+diesel+particles+h... An explanation here to why ~ http://www.lungoregon.org/air/Diesel.html

"... PM (Particulate Matter) has now been linked to a broad range of adverse health effects, both respiratory and cardiovascular, in epidemiologic and toxicologic research. ... The primary impetus for the 1997 PM NAAQS and the current proposed revision has been epidemiologic evidence that associates PM with increased risk for mortality ..." ~ "Small Particles with Big Effects", William N.

I think one of the problems comes from trying to use PHP too heavily as a template language, and then people try and do the shortest thing possible even if their source looks horrible. (I know I've done some icky things in the past to make the HTML look nice at the expense of the PHP file looking worse, or vice versa.) It's very easy to fail in separating code and visible content in PHP, which is great for some cases but bad for others.

You'd be surprised how little comment deletion there is outside of Ask Metafilter (where all comments have to answer the damn question). Pretty much the only comments deleted from the main site are personal attacks. There's an active backchannel for discussing such things where almost nothing is deleted.

They take great pains to avoid banning people (excepting spammers, who get their signup fee refunded!), though sometimes they dole out timeouts. The community policing means that the shitty users tend to disable their own accounts.

pg takes the opposite approach, applying a single assholish technical approach to all problems: hellbanning for everyone!

IANAL. That said, I believe the relevant law is http://www.mass.gov/legis/laws/mgl/272-99.htm and the key element will prove to be whether using a cell phone as a video/audio camera would constitute a "secret" recording of audio as required by definition B4. (Apparently, with Glick's original case dismissed, there's a chance that it would not suffice.)

In terms of his suit, anyone can sue anyone for anything. It's the winning that's hard. I can't imagine any cause for action on impairing his freedom of speech, nor that sufficient probable cause did not exist to effect the arrest. While I don't like how the law is written, and may not agree with the premise, the law is the law and it's easy for an officer to believe that they have probable cause for an arrest under that law. Frankly, I think they had PC for the arrest, even as I wish they didn't and wish that even if they had, they'd have chosen not to make that arrest. I can't see how Glick can meaningfully win this case...

I disagree about the long-term reliability of SSDs. Intel's X25-M has a 5 year warranty. They claim that writing 100GB/day for 5 years will not cause it to fail. If we compare the technologies in terms of reliability, flash has three things going for it:

1. Flash degrades predictably over time. Manufacturers know the average number of write cycles a cell can sustain and design SSDs with "spare" flash and wear leveling. They can engineer the expected lifetime of the drive. Hard drives usually fail spontaneously.

2. The most common failure mode for flash cells is to fail on write. Even if a cell gets "stuck," the data can still be read. Hard drives fail on read or write, and in most cases all data on the drive is lost.

3. A 3.5" 7200RPM drive's platters spin at 70mph on the outside edge. The head gap is measured in millionths of an inch, making them very susceptible to vibration and shock. Since SSDs have no moving parts, they're practically immune.

There are really only two disadvantages of SSDs: cost and capacity.

China's "healthy" respect for education boils down to one standardized test which it uses to assign people to what they'll get to do for the rest of their lives. And censorship of facts because they're inconvenient isn't healthy either. Just like we do here in the US.

Anyway, I'm familiar with why Guido doesn't want them, and I totally respect it, and I write 99% of my personal code in python, so I clearly don't think it's a huge deal. It's just something I wish python did have, is all.
I'll agree that sci-fi geeks have vastly inflated opinions of both fields. That said, advances from AI have contributed to your quality of life significantly. Space exploration has been one massive money pit since we got satellites working.

AI:

+ Keeps your inbox free of spam.

+ Is more responsible for black Americans being able to get a home loan without being discriminated against than any act of Congress.

+ Saves you money on your car insurance.

+ Runs the factories that make your goods and the warehouses that ship them.

+ Loses video games against you every day without complaint, by being hopefully challenging enough to flatter your ego without actually being difficult.

+ Can do some surprisingly sophisticated things with language analysis these days, such as determine whether you're a man or woman by analysis of a sample of your writing.

And the coolest thing about AI is that we've accomplished the above feats of magic so freaking routinely that people don't even think they're AI anymore. People will only admit something is AI when we can't do it.

Space Exploration:

+ Artificial satellites.

+ Slush fund for defense contractors.

+ Tang.

I wonder where this myth that "[websites] on the internet [are] I/O bound, not CPU bound" seemly implying that optimizing CPU usage is a waste of time, comes from.

Since the I/O bound generally comes from latency, rather than total throughput, the number of concurrent connections a single webserver can handle is often proportional to how much memory and CPU resources each connection uses. If you have an asynchronous design for your server, concurrent connections don't cost physical threads - they just cost the bookkeeping overhead in the kernel. The faster you can switch between those connections, and get finished with work on them when I/Os complete, the fewer physical machines you need to serve a website to a given number of users.

Or to put it another way, the saturation point of processing asynchronous I/Os is CPU-bound, even when speeding up individual requests is I/O-bound.

You may be right. And I am glad that I visited Turkey in 2008 and not 10 years earlier. They have made huge strides but there's still a lot of progress left to achieve. While I was there they banned youtube several times for showing silly (Greek) videos that claimed Attaturk (the republics founder) was gay.

My thoughts exactly; this is really not too exciting. (I will disagree that web apps are never CPU-bound. That has always been the bottleneck for me.)

I haven't seen the source code yet, but I think Chicken Scheme did everything HipHop does but many years ago. And, there are some hard problems to solve when implementing Scheme, notably handling continuations. PHP is much simpler in comparison.

I do see good things coming out of this project, though. As people are enticed by the biggest temptress in computing, speed, they'll learn to run and deploy web applications that aren't as simple as "ftp this HTML file to a directory". Once PHP's only advantage over other languages is gone, and developers realize that it wasn't that big of an advantage, they'll switch to better programming languages. Then we can forget PHP ever happened, and the field can move on!
If space exploration includes the Apollo project (which I assume it does) you should add integrated circuits, CNC machining, freeze dried foods, LED's, aircraft anti icing systems, solar energy, water purification, the Internet, and probably many more I can't think of right now.
Most hard drive faults do not cause an instant loss of all data on the drive. (Look at SMART reallocated sectors/events. Take 50 of your drives that are "working just fine" and I'll bet that 10 of them have reallocated sectors.)

When people say I/O-bound, I think they mean disk-bound. Using less CPU really won't help you there.

Whether Web servers really are disk-bound is a different issue.

If you have an asynchronous design for your server...

This is PHP we're talking about.
my personal definition of a 'startup' is a business that aims to grow rapidly, acquire venture funding, and hire more employees. this seems like a (successful) small business, not a 'tech startup'. the author's hope is not to become the next 37signals, meebo, facebook, google, etc.
It means that somebody has a really weird idea of what a spaceship looks like. As the article text says, it looks like a debris cloud that is getting smeared out by sunlight pressure. So, if it's a spaceship, it's a spaceship that exploded already.

Seems the quality of alien spaceships is going down. They used to at least be able to travel at least four light years, reach Roswell, New Mexico, then explode. Now they travel four light years minimum and explode before even reaching Earth. I'm not really certain that we have much to learn from our neighbors who seem so desperate to contact us, yet so frightfully incapable of it; we don't need to travel the stars to blow things up, we can do it right here. Seems more efficient than their approach.
Yeah, exactly. The reality is that most web applications don't handle IO sanely, and have a 100-400MB process sit idle while waiting for the results of a database query (or for a slow client to suck down the rendered page).

Using a proper threading system (and I mean lightweight threads, not OS threads) makes any application CPU intensive instead of IO-intensive. If the app doesn't use all the CPU, it's performing as well as possible. If it does use all the CPU, then making it run faster is a net gain for your users.

This is PHP, though, and you would have to jump through a lot of hoops to remove the IO overhead. At least HipHop uses libevent, so at least apps won't be blocked by slow clients anymore.
Hack Brings Mac OS X to the Nokia N900
Because of differences like this ... I believe that the work done on HipHop represents a fundamentally smaller challenge than that taken on by the teams working to improve the implementations of languages like Python, Ruby, or Javascript.

I think this is true. On the other hand, it's not Facebook's job to do research. If they can benefit equally from solving a simpler problem, then that's what they should do.

I agree with the author's points, I just want to make explicit that Facebook didn't make wrong choices. It's just that their work is probably of limited value to everyone else.

A better example is modern x86 CPUs. You feed them x86 instructions, but that is not the native language of the CPU; everything is translated into the real underlying (RISC) language as the x86 instructions are encountered.
