Houston is also in the process of building a "new-style" tram network: https://en.wikipedia.org/wiki/METRORail

I'm personally a bit lukewarm on them. I think many of these systems, especially the longer ones intended as major backbone/commuter routes are mainly "backup" plans forced by cost issues. The city has identified a backbone route that would be well served by a rapid-transit line, but the capital costs to build one are impossible to come up with in the current transit-funding climate, so a light-rail/tram line is built as Plan B. Besides Houston, another example that imo is clearly a case of "should have been rapid transit, but we couldn't afford it" is the Expo line in L.A., to Santa Monica. Santa Monica is becoming a major tech hub and has huge commute problems, but the system being built simply doesn't have the capacity to offload more than a small portion of the current car traffic.

An in-between approach, sometimes called a "light metro", better serves in the commute-backbone role imo: light-rail-like vehicles, but at very high frequency (e.g. every 2-3 minutes) in order to enable the line to provide significant throughput. The Copenhagen Metro is an example of such a system. But running at those headways reliably almost requires a grade-separated right-of-way, which negates a lot of the capital-cost savings of putting in a street-level tram (though it's still somewhat cheaper, because the shorter trains mean smaller stations and a tighter max turning radius).

Rabbit rescue. I volunteer at a shelter in Maryland. Clean cages, administer medicine, check food and water and hay, brushing, and provide lots of scritches. Shameless plug: www.esrrec.org. If you visit the website, the "donate" and "volunteer" rabbit photos are my own pets.

Music composition. I have a nice little midi setup. A full sized synth, a 25-key controller, a launchpad controller with external track controls, and a special device that allows me to connect a tablet and a smartphone to use as additional controllers or sound devices. Ableton Live and Finale. Lately I've been composing music for weddings, but also dipping my toes into electronica and ambient. I'm an old hand at Finale, still new to Ableton.
Ask HN: Scriptable IMAP/SMTP servers?
I'm looking to build a mail system that can be accessed via normal IMAP/SMTP clients (mobile devices, Apple Mail/Thunderbird/Outlook, etc.) but with a decent scripting ability. The goal is to have inbound and outbound emails to be reviewed by a third party before they're delivered. Googling has revealed a number of dead tries at making a Node IMAP server, a long-dead Lua-scriptable IMAP server, but nothing particularly usable.
yeah +1

Like many devs, my jobs and most of my hobbies tend to be very cerebral, and I spend almost all of my time deep inside my own head. I think living this way contributes to feeling disconnected from the world and ultimately anxiety.

Rock climbing is extremely grounding, even compared to other sports. You have to use all of your muscles, and pay careful attention to what your hands are doing. You feel the weight of gravity and the stress of being in a high place, and then this wonderful feeling of accomplishment when you reach the top.

Nothing puts you in the 'now' like climbing. It's like the perfect therapy for spacey people.
No racing for me yet, but I have a track day tomorrow. The level of concentration required is astounding. I still remember being amazed at the difference between my first and second track days. How much more I could SEE after I started to relax, and the tunnel vision faded away. :-)
As an SF resident, I can say that every light rail line sees heavy use by locals.

I think oblio is confusing SF's cable cars (historic and almost exclusively used by tourists) with SF's light rail/streetcars (quite modern and used by everyone).
Where's part uno?

Look it, people can talk and read all the shite they want but unless they actually do and show results – they're a load of hot air. I do recognise a vibe from your post that I've encountered. Freelancers who have been freelancing for two years and write a book about it. A load of shite most times. Common sense and basic business practises are whats in the book. And they're written in this extremely irritating tone. But hey, if it helps some people out – great.

Your last sentence is revealing. The days of knowing some extra sweet photoshop tricks and that actually mattering is over. No one gives two fucks about your excellent layer effects. What does the image communicate and is it relevant for the audience? I can find out how to make anything I want – but if it doesn't affect the bottom line (money or action) why would anyone give a shit. That's just craft.

Although you reminded me of a great old wives tale of Eddie Van Halen turning his back on the audience to play the tapping parts of his solos because he was scared someone would steal his 'trick'.

Ad 1: Do anyone really need LTS for desktop OS? Especially since it's quite experimental distro so rapid changes and experimental solutions are part of what Fedora is.
I'm into 3D modeling. It's challenging and makes you always think ahead of what you are currently doing. It has a lot of similarities to programming actually, except that since it's my hobby I'm not trying to be extremely productive and allow myself to work at a slow pace. It is pretty relaxing.
Being somewhat familiar with a 3D workflow will also make you appreciate videogames or the CGI you see in movies even more.
It also has tons of applications. As an example, I recently moved into a new place but I wasn't sure all my furniture would fit into my room, so I made a rough 3D model of the room and of my stuff and quicky tried different configurations to see which one would work the best.

I've also picked up photography. I don't like sports but I don't mind walking, so it's a great way to actually go outside instead of sitting at my desk all day. On the downside it is pretty addictive and can quickly become very expensive.

From what I seen this is an issue between the main Fedora repo and RpmFusion. The nvidia drivers have the same issue.

Fedora upgrades the kernel, but RpmFusion havn't re-built kernel modules yet. So you do an yum upgrade, and are left with a new kernel, without the modules you need. There's the akmod- modules that's supposed to recompile itself on a kernel upgrade, but in my experience that works about half the time.

Small things like this gets old really fast. Even if there's workarounds, people will have to remember those, and it's easier to find an alternative that just works instead of listening to people saying "but that's because" or "you can just".
I hope so. This story makes me feel dirty just for being interested in computer security.
No problem!

There's also one more book I was trying to find which basically recasts normal linear regression in the geometric projection terms that most people know but that are never emphasized when learning it. The nice part of that method is that then you can extend the geometric interpretation to manifolds and get, I believe, GLM very naturally.

This was discovered months ago: https://www.schaafpc.com/bitly-viglink-publisher/

As @DanBlake had mentioned, there is a serious FTC issue where individuals that were casually linking to a merchant are now unwittingly becoming advertisers. There's a decent snippet in the comments of the above link about that.

They claim that they are just turning non-affiliate links into affiliate links.

They also claim they are not overwriting other affiliate links.

So do they automatically recognize all other affiliate network redirects? What about direct linking affiliate programs? What about Pay-Per-Call programs? There are a number of ways this can go wrong and take money from other affiliates by hijacking the links.

Not to mention the fact that there is very little benefit to the merchant here - that is traffic that quite clearly they were getting anyways. There is complete intent to link to them, so why must they pay VigLink and Bit.ly for shortening the URL? That's a service being used by the individual linking to the merchant. It's not worth commissioning on, there's very little value to the merchant.

If you have an affiliate program with Viglink, please contact them and request they remove ALL URL shorteners from their program - it's not just bit.ly, it's tinyurl as well, and a couple others that I cannot recall at the moment.
Just on a whim, I stuck the little 6" whip antenna on the trunk of my car and plopped my laptop next to it, just to see what I'd get.

As for the "experimental" and "rapid changes", I can assure you it is far more stable than Ubuntu by miles and miles. Just don't install it at the first day of its release; wait for a month or two.

This is a tangent, but don't write off heart problems TOO much--don't ignore symptoms just because you're young. I know that's not what you were saying, but a very healthy and young friend of mine (serious lifter too) had a heart attack recently. It started out mild but he tried to "push through the pain." Bad idea.

> If it's physically possible to go climbing now without definitely getting fired, you're going.

Hahaha, it's like this with every outdoor sport I can think of: Climbing, surfing, hang-gliding, mountain biking. When something is crazy fun to do and gives you that adrenaline boost/endorphin rush/seratonin spike, work can wait... as long as you're not getting fired, life is good :P
Writing your own crypto implementation is just like every other instance of reinventing the wheel, but more so. Namely, don't be a dilettante.

It's actually perfectly OK to reinvent wheels. Reinventing wheels is how people learn to build wheels and eventually invent new, never before seen wheels. Where we as programmers get in trouble is that we frequently reinvent a wheel once, and then drive around on it for the rest of our lives.

If you find cryptography interesting, try your hand at it. But don't just code up the first implementation once, slap it on a web app, and use it to protect your customers PII. Don't be a dilettante. Write lots of crypto implementations, and try to find the flaws in them. Read lots of books, read lots of other people's implementations. Whenever a new exploit of one comes out, try to understand it and try to find similar problems in your own code or other implementations (or figure out why a particular implementation doesn't have that flaw). Write more implementations, read more books, talk to other cryptographers.

It's not a crime to be interested in difficult things, but it is important to recognize that difficult things take a certain level of skill and devotion. Each of us has to decide which difficult things we want to devote our time to and which we want to casually watch from the sidelines.

The feature I miss most is being able to link text.

Right now people just paste links as-is, or use this numbering syntax [0] which works but could definitely be replaced with something better.

After that, supporting lists and fenced code blocks with syntax highlighting would be handy, though those are probably more prone to abuse.

> Still a bit odd the concentration of western political parties in the right-wing authoritarian section of the graph

Dunno, if you consider that much of the anglosphere is patterning itself more and more after US politics which lives solely in the top-right corner of the top-right quadrant it makes sense that they would coalesce there. And "labour" parties have definitely been shifting their stances towards US dem inspiration.
I think Gnome 3 doesn't quite "do" polish as much as Unity. I am very fussy about fonts looking right, and I'm afraid that at smaller sizes, the font scaling in the Gnome terminal just looked wrong, whereas Unity is perfect in this sense. It's a tiny detail, but Unity kind of feels as polished as a Mac. It also has better dual-monitor support because you can independently set the font scaling for different dpi on internal/external monitor. Crucial if you run a high-dpi notebook in conjunction with a normal fullhd monitor. On Fedora Gnome I had ugly mis-sized title bars and UI fonts on at least one of my monitors.

Second, I do CUDA development, and there are three Cuda 7.0 toolkits downloadable for Ubuntu 14.04 and 14.10 right now, but Fedora 21 is still "coming soon" and has been "coming soon" now for over 6 weeks. Deja vu a few times already on this. Moved back to 14.04, even though I loved the progressive ideas and clean look in Gnome 3.

I still run Fedora on a cubietruck for fun: no problems, works well, but I use the e17 desktop which is a fantastic retro reminder of the 90s if you need an antidote to Jony Ive. It's fast, lean, unapollageticaly black, and terminology looks great and has some neat features for inline graphics if you're a terminal junky.
Juggling: It's awesome because there is a vibrant community pushing the limits of what's possible. There are so many different things to juggling (balls, clubs, rings - But also devilsticks, pois, diablos, yoyos, ...) and you can always learn something new. It's also pretty easy to start and you can learn new tricks fairly regulary, so (at least in my experience) you don't hit a wall that often.
One very cool thing is that you can get started with 3 tennis balls or other objects and, if you think it's worth it, migrate easily to "real" juggling balls and other things that cost more.

Sprinkling a Little Celebrity Stardust on Silicon Valley
>So yes ARM is great. But let's be honest, Intel is vastly, vastly ahead when it comes to anything that is not a toy.

Well, I agree if you're using "toy" as Romans used "Barbarian". If you mean by "toy" anything that's not desktop, then yes.

But if you look at what happens in an industrial setting and do a teardown on those tools (oil industry, for example), you won't find Intel processors, you'll find FPGAs and ARM processors in a bunch of tiny toys that cost about 75k each.

So it appears that "toy" is not what the device is destined to be, but what the people who buy it end up using it for.

As with any programming language, you can print "Hello world" and leave it at that, or you can build a massive thing.

The limits of imagination are unfortunately reached way before the hardware limitations are.
I really like the use of tools that make focus the default, low-motivation option. If you're not on a Mac, Firefox has LeechBlock[1] and Chrome has StayFocusd[2]. Also, if you're on HN, there are built-in settings under your username you can use to limit how long you can access the site for every few hours.

Ironically, that's why I'm on HN now. I know I only have 15 minutes and then I won't get to use it for another few hours. :)

I bought a bunch of New Balance Minimus on sale for around $70 each. Many of them have >1000 miles on them, and they're going strong. I have yet to retire a pair. And the upside to running clothes is that they're all synthetics so they last forever. I still have pretty much all of the running clothes I've ever bought. Not quite free, but awfully cheap.

Neat site. I like the presentation of talking points.

My question, though, is how does this differ from other similar sites such as privacytools.io? How do I reconcile the privacy tools listed there with the ones listed here? Most of them are different.

Ultimately, whose recommendations should I trust?
I really appreciate the resources provided. But I'm not a fan of the website suggesting that I want/need privacy because I have something to hide.

Ubuntu provides less than a year of support for non-LTS releases. Anecdotally, this is quite annoying because the overlap between two consecutive non-LTS releases is normally a couple of months and their quality control for new releases is not great.

I'm still mad that Redhat spun off fedora in the first place, 3 days before the announcement I had bought a boxed copy. I returned it, and switched to Suse. Then when Suse got buddy buddy with Microsoft I switched to Debian, then Ubuntu, then Mint, and now back to Ubuntu.
I run into the opposite. St doesn't play well with n/curses in my experience (mostly corrupt characters on display), and the easiest solution I've seen is to run these programs in a Tmux session. I use Tmux all the time anyway, so this doesn't add any extra overhead for me (mental or system).
I bet some people did. But when you look at the population as a whole, it probably looks like 5% "I can add linux-kernel to the ignored updates list," and 95% "I'm switching back to Ubuntu because it breaks less."
Well, we all have something to hide.

Also, last time I checked, KDE, which I use, was many releases behind. Also, in Centos6 which had python 2.6.5(IIRC) was a PITA to update. Actually you couldn't so you had to maintain a source-based installation
of 2.7.X side by side. In general you ended up having a source distribution, because the repos had really old stuff. For web development stuff, it was really impossible to have it as your main system.

Maybe CentOS 7 is a bit better, but still I don't think you can use it for modern desktop/devel operations.

It's funny in the end. Parts of languages syntax reinforce other parts. In lisps you cannot write a-b as an arithmetic expression. Sequences of characters are symbols, and that's it. But also, lispers don't really care about infix notation[1] they have abstract polyadic operations: - + / * all take a list of zero or more arguments. (- x y z ...)

[1] And IMO people shouldn't, basic arithmetic isn't that frequent or complex enough to need such a dedicated treatment. But that's another lisp thing, you care more about having DSL opportunities for anything rather than a fixed set.

"At Magnetic, we’ve switched from running all of our performance-sensitive Python code from CPython to PyPy, so let’s consider whether these code optimizations are still appropriate... PyPy is incredibly fast, around an order of magnitude faster than CPython in this benchmark. Because PyPy performs more advanced optimizations than CPython, including many optimizations for classes and methods, the timings for the class vs. closure implementations are a statistical tie."
