The Tesla Valve is a leaky valve, which is why we still use one way valves with moving parts. The amount of leakage depends on the design of the valve and how well it suits the incoming fluid. A faster fluid will result in a different looking valve compared to a slower fluid. The valves design would also change based on the viscosity of the fluid.

Would you pay for this? For the last 3 years I've been creating a platform for this kind of servers for a small spanish ISP. It has grown to 15 Openvz hosts. A rails app connects to the host to create the virtual machine. Centos is installed and configured with puppet. A rails app is installed in every server and used to configure the accounts, domains, etc.

Postfix, Cyrus, IMAPS, SMTPS, POP3S, HTTPS, Sieve for filters on the server, roundcube as webmail (on a new product I would pay for @mail), decent spam filter (right now we run our own system based on commtouch and spamassasin), etc. You can export the whole cyrus mail storage folder or export mail to other server with imapsync, same thing with the database that contains the account, domains and aliases, so you are not locked. Billing can be done by hard drive space or accounts. They are also good as outgoing mail servers because you are on your own ip.

I run everything by myself, right now we have 126 servers with about 12300 accounts and thanks to puppet it's really easy to admin. I've always thought that I should try to do it by myself.
Prohibition was rejected because it was forced upon people, but I could see people start to "naturally" reject alcohol as they have tobacco. Drinking and driving used to be the normal thing to do, now you are an evil, evil person for even considering it. The straight up consumption of alcohol could easily go the same way.

OK. So let me spell it out for you (and others, who appear to be confused):

Obama is a charismatic leader.
Hitler was a charismatic leader.
Obama was elected democratically.
Hitler was elected democratically.
Obama wrote a biography. Barack Obama - Dreams from my father
Hitler wrote a biography; Mein Kampf
Obama held a rally in Berlin.
Hitler held a rally in Berlin.

...etc.

Therefore, Obama reminds me more of Hitler than anyone else does. (approx. quote from poster above)

Now, do you see why this is an idiotic comparison?
I'm a self-respecting hacker and I use Yahoo mail. I guess this would put me even lower in author eyes.

It's just convenient (where I can access the Web I can access my email, no spam). As long as I am aware of the that fact, I can encrypt my mail if necessary or use alternate means of communication (such as a different email service possibly my own, etc).
Gmail's spam filters are so good because they have a network effect going though, I doubt one spam folder would achieve much, you need a much bigger sample of all the spam than one account could ever attract

I think that's part of it, but I do think satisfying some of the major demands dissolved the broad coalition; moderate liberals, especially white liberals, were largely satisfied by the civil-rights legislation, and dropped out of the movement, leaving a much smaller activist core. The SNCC took a huge nosedive in membership after 1965, for example, and even MLK found it harder to muster the same levels of support for his post-'65 causes (like desegregating Chicago, and ending poverty).

>Slavery, Torture as a judical tool and blood feuds are also literally as old as human civilization and yet have recently fallen out of favor.

Those things all fell out of favor because they inflict direct harm upon others, not because of their long-term health effects to the individual.

And as I noted, the temperance movement was largely driven by the harm inflicted upon by alcoholics on their families, which resulted in impoverishing women (largely because women weren't viewed as fully autonomous at the time, something else that's socially fallen out of favor).

As for the TestWebP iOS lib itself, it takes 25 LOC to load an image, which takes 1 LOC with system libraries. Somebody needs to go in and put a category on UIImage to do the heavy lifting.

I just ran a grep across about 15 iOS apps I develop and the average size of art assets is about 1MB. So this is a neat hack, and I am sure there are apps out there with 300MB in art assets that could benefit from it. But for the typical app, not worth the effort.
I live in a world where I expect and need email access from anywhere, any computer, any mobile device. I also expect tight integration with calendar and contacts. Those requirements mean I need webmail and ActiveSync. IMAP Idle (push) has reasonable mobile support, but CalDAV and CardDAV have limited support -- so ActiveSync it is. ActiveSync is non-existent in open source software. The best webmail client I've used that can be used with any IMAP server is Roundcube, but it doesn't have calendar support. Zimbra is the only open source software I've seen with good mail+calendar+contact integration, and it has a good web client. Perfect, except the open source version doesn't support ActiveSync, and is missing the backup utilities. The commercial version is a minimum $399/year. Fine, I'll pay it.

Now I need to host it. I want my email to be highly available. So I want to cluster two Zimbra servers in one data center, and cluster two backup MXs in another data center to store and forward my mail if the Zimbra DC drops off the net. Zimbra supports HA clustering with Red Hat Cluster Suite or through the HA clustering of virtualization like VMware. RHCS requires a highly available SAN as backend. Damn, an HA SAN is going to be expensive. Maybe I'll do VMs. But virtualization products like VMware and RHEV will require an HA SAN or NAS. Fine, I'll build an HA NAS with open source.

I'll deploy two ZFS heads in an active-active cluster... wait, clustering will require purchasing licenses from a company like Nexenta. Or I can get active-passive from iXsystems. So I'll buy the cheapest Nexenta license which is $1725, plus the HA Cluster license for $4900. I'll connect those heads to a dual-controller SAS JBOD which only costs $3795.

I'm now going to fly all this gear to a non-US-friendly location to install it in a data center. Each piece of hardware as redundant power supplies. I will connect the power supplies to separate power distribution units, the PDUs are on separate circuits. Each system has dual Ethernet going to separate switches, which in-turn uplink to dual-clustered routers, which uplink to the multi-homed internet provided by the data center. Because I'm on the other side of the world I'll also have a console server, and the PDUs can remotely cycle power.

Awesome! I now have the email setup I want, and it only cost me $30,000 and a month of my time!

Or I can sign up for Google Apps, where they will host my domain's email, and provide all the features I want, and have a better interface, and not require maintenance, and have better uptime, all for free!

I've administered old school sendmail+procmail setups without webmail. I've administered Postfix+Dovecot+Roundcube+LDAP. I've administered Zimbra. I've administered Google Apps for Business. It isn't worth my time and money to do anything other than Google Apps.

i tried running my own mail server for a while. it's mostly tedious, but there was some settings and configs to poke at. the problem is that playing with configs and live mail servers don't go together so well, half the time my email server was down and mail wasn't getting through because i was playing with things that shouldn't be played with.

so now i use gmail. no matter how much i try to screw that up, my mail still comes through.
Respectfully, no.

The primary issue in spam filtering is not that we don't have training corpora, it's that spammers are very efficient at finding holes in your system.

One example is when the Hotmail team first enabled keyword filtering. When the spammers found out experimentally, they began injecting HTML comment tags into high-weighted words like "free", breaking the model. When the Hotmail team took steps to combat this problem, the amount of spam that employed this technique dropped from 5% to close to 0%[1] in a matter of days.

Spam detection is complicated and hard.

As recently as 18 months ago, I routinely got solid customer service from AT&T. While the wireless service itself was really sketchy in NY and SF, any account problems were handled with competence and care.

Given the incredible blowback they'd received from their poor iPhone support, I always felt compelled to tell the people I ended up talking to that they were doing great jobs, and that in spite of what was said in the press about them not having their act together, I found them to be on their game, and that I really appreciated the effort they were making.

Then something changed. Intelligence and responsiveness went off a cliff. On the occasions I did have to call I ended up so deeply infuriated that I'd find myself becoming angry BEFORE having to call again - even months later. It almost seemed that they'd adopted a posture of calculated incompetence, specifically designed discourage people from calling them.

Within a year (and after a series of truly appalling encounters) I'd gone from publicly defending them to hating them with an intensity bordering on incandescent. Were their service any less vital to my life in general, perhaps I'd feel more sanguine. But given the central importance of wireless connectivity, a "service" relationship costing north of $100 per month and delivering nothing by dropped calls and furious anger quickly made it to the top of of my dump-judiciously list.
This is a pointless comment, but with all the whining here I feel like making a counterpoint.

I run my own mail/irc/web/file/etc -server. Postfix on OpenBSD with maybe 10 config variable changes to add a DNS blacklist of my choice + secondary MX for a friend. FDM for sorting mail and piping stuff through bogofilter. Mutt and SSH to read mail from anywhere.

I post my email address everywhere and get about 10-15 spam mails per day that escape the blacklist. Of those, 99% are sorted out by bogofilter. I scan them for false positives like I scan other mailinglists for interesting topics. There are about 700 mails from various ml's every day. The maintenance time this setup "costs" is recovered in less than a week of not having to click through the slow gmail interface. There is nothing to do. Backups are done via rsync and cron, but they have to be done anyway.

Point is, running a private mail server is easy. But then I don't call myself hacker...
You think a "maximize the buck" move by Google would be to start rooting around in your personal drawers?
By the way, I meant someone creating an application you could install locally, instead of just being a gmail clone hosting everyone's e-mail at once.

The difference is that we have clear evidence that tobacco is vastly harmful to your health in the long term. Alcohol? Not so much.

Pretty much everyone agrees that it's bad to be an alcoholic. Most people get annoyed with people that routinely get sloppy, out of control drunk. That's already socially unacceptable.

The general consumption of alcohol becoming an outright social faux pas, though? I just don't see it happening any time in our lifetimes.

Yeah, but it's also email. You could delete every email you've ever created and everyone who's ever saved their copy still has their copy.

Even if you were trying to be all sneaky about your email by having your own service set up somewhere, you're still making copies of everything you send by virtue of sending it. It's more vectors for the government/Evil Google/whoever to need to scan to get a picture of the data you're creating, but it's not impossible.

I know you're just making a point, but to the people who actually are all tinfoil hat, this whole conversation to shift to whether or not you should even use email as a method of communicating.

Would be interesting to see what percentage of posts covered the really big companies vs startups on there. Feels pretty skewed towards the ever small and often pointless detail of the big tech companies rather than startups.
Most of the companies back then didn't have that kind of shelf life either. Making an investment in an early stage company is inherently risky.

If your goal is to get rich via investment opportunities I would not recommend trying to win the stock option lottery via the employee option pool as the best strategy to achieve that goal.

While I'd agree that much of the foundations of modern computing were built upon some form of free software, I disagree that it's primarily Stallman's work. For one thing, OS X is based upon FreeBSD and Mach, neither of which are affiliated with the FSF. And I'd argue that the foundations of Google and Facebook are PHP, Apache, Python, etc. which are also not FSF.

Of course it's a difficult exercise to try to imagine how things would be different had the FSF not been created, or what influence it had upon the creation of software that wasn't directly affiliated with it. Obviously gcc has been one of the most prominent GNU toolsets featured in modern operating systems, although that appears to be changing too (Xcode replacing gcc with LLVM).
Setting the privacy and security issues aside, I wonder why do so many self-respecting hackers use the Gmail web interface (instead of, say, fetching their mail via IMAP and use another client). Dedicated mail clients like mutt can be much more efficient (keyboard-driven) and are a lot more customisable (run macros, pipe mail through external commands, etc.). I wonder why so many hackers aren't put off by Google's "one size fits all" approach.

The R3 zoning district (all that orange on the map) allows fairly high density - FAR 1.05 maximum and upto >40 DU's per acre. [Mountainview, Ca, Code of Ordinances, Chapter 36 Article XII available at www.municode.com]

However, the primary land subdivision pattern of many small lots (and consequently many owners) makes assembling parcels suitable for redevelopment at higher densities not just expensive, but difficult.

Furthermore, existing high rents mean that the value of the land based on existing cashflows may make redevelopment infeasible once the cost of new construction and land acquisition is amortized and the higher returns associated with the risk of development must be paid.

Obsolescent housing (and other structures) remain because they are profitable and can be valued on an existing income basis and thus traded with known risk.

Higher density projects may be possible, but the market may not be able to absorb the units if the rents are significantly higher - and of course, higher rents are also likely to be untenable for voters as well.

Emotional sensitivity to computing machinery ought to be generally recognized, and not only on April Fools Day.
That sounds pretty identical to my upbringing, and I feel I'm the better and more level-headed for it. However, I've never met anyone who thought it must have been emotionally scarring - I can't comprehend people who would think that teaching kids to be self-reliant and responsible would be scarring. Sadly, those seem to be the scarred people.
What a well thought out proposal. Adding emotions to TCP packets, which are becoming increasingly important in our interconnected global world, could truly revolution the internet as we know it. The Emotional Web is the clear successor to the Semantic Web and the Social Web. It has tremendous possibilities for innovation and new startups. Note this statement by the author:

This document does not seek to build a sentient network stack.
However, this framework could be used to express the emotions of a
sentient stack. If that were to happen, a new technical job class of
network psychologists could be created.

The idea of a sentient, emotional network stack being created may seem frightening to some people, but as the author notes:

Some organizations are prohibited from using [the evil] mood by mission statement.

which should help alleviate some of the fears people may have of evil sentient networks.

Plus, by adding emotions to packets, we're a step closer to finally solving one of the most persistent problems in online text-based communication: determining if a message is meant seriously or sarcastically/facetiously.

Every now and then the possibilities of a new technology truly amazes me. This is one of those times.

I firmly believe that the Emotional Web is the future of the web as we know it.
