Why would developers want/care about long-term support?

There are a tonne of packages out there that will grab source from a repository and compile in a root jail. You now have binaries for every permutation of dependencies ever produced. Test harnesses (you remember those, the things developers are supposed to use) can give you a list of regressions and compatibility bugs within minutes of a commit.

Long term support encourages developers to be lazy, to presuppose things that may not be true.

Developers are best supposing nothing, testing everything and isolating the conditional (which they should be doing anyway, good software design). If you don't have time to be competent, then you certainly don't have time to be incompetent. So find time.

As a developer, I categorically state I hate Ubuntu for development work. It is horribly sub-optimal, poorly organized and package management is unstable and space inefficient. It also doesn't run on several of my white box PCs. Very standard, old white boxes.

Red Hat is only marginally better on efficiency, but recovery is ugly.

Gentoo would be ok, except that compiler flags are a bother. I can't use utilities for using profiles to calculate optimal flags when those flags will vary down the dependency chain.

Linux From Scratch is good, it's essentially how I put together my own systems between the last of the MCC builds and the first Red Hat I considered tolerable enough.

Look, I don't expect miracles immediately. Only after the updates from the repository. There simply isn't any reason for so much broken code and suboptimal configs. Not when Ubuntu is run by a billionaire who can afford a few extra hard drives for high-end builds.

Just over a month ago, Steam has a sale on some very big games, like Wolfenstein: New Order and Splinter Cell: Blacklist. (maybe it's all the colons that take up the space.

It doesn't take too many games at over 20gig each, along with Netflix for the wife and streaming music before you're knocking on 150gig.

Why in the world the Wolfenstein game came out to over 40 gig I'll never know, but sure enough, for the first time I got the email from AT&T that I was at 90% of my limit. Fortunately, it was two days before the billing cycle rolled over, so I didn't have to pay.

This is why I love Slashdot. I discussion of internet overcharging and ATM encapsulation quickly pivots to the etiquette of showering with gay men at the gym.

Imagine if you went to buy milk and bought a gallon but were charged for 1.25 gallons because of spillage in the bottling plant.

Or to be more similar: you got charged 1.25, because they determine the price by weighting it and thus are also weighting the glass milk bottles and the hard plastic crate carrying them.
And when you ask them why you don't get the same amount of gallons that you measure in your kitchen and on their bill, they just answer "No, everything is okay, our bill is 100% right.". Without ever mentioning that you need to take that overhead into account. Without you having any way to check it or control the milkbottle+crate weighting process neither.

I thought everyone knew this, or were able to google it especially if they are able to upload something like DDWRT to their router. Perhaps I had too much faith.

especially in AT&T if nobody he's ever spoken with about the issue knew enough to mention encapsulation. It doesn't sound like he's a dope, just possibly missed this factor. Somebody there could have simply asked him, "are you counting the overhead of PPPoE and ATM?" and then his post may have been entirely different, if it even existed at all.

With millions of home users and thousands of techs, the onus should not be on the customer base to understand how the vendor's product works internally.

Most places I've seen measure with encapsulation, because it's easier. The problem's not with the meter, it's with the small print

The problem actually is with the meter, if you're not allowed to see the meter.

"We're going to charge you based on this gas/electric/water/phone meter, but you have no way to verify the reading" is something the PUC wouldn't accept other than in the case of "the Internet".

the rules and licensing that happens on the State level should only be applicable to those roads.

Please explain the legal theory for the State being able to a-priori take away your right to free travel without due process of law and how that fits with, e.g. the 5/9/14th Amendments and the privileges and immunities clause. Remember, they seized most of these roads, however long ago.

Here's a more technical discussion from NHTSA. At page 74-75, the data elements of the Basic Safety Message I and II are listed. The BSM Part I message doesn't contain the vehicle ID, but it does contain latitude and longitude. The BSM Part II message has the vehicle's VIN. So this is explicitly not anonymous.

Back in the 1980s, when Caltrans was working on something similar, they used a random ID which was generated each time the ignition was switched on. That's all that's needed for safety purposes. This system has a totally unnecessary tracking feature.

Most of this stuff only works if all vehicles are equipped. It also relies heavily on very accurate GPS positions. However, there's no new sensing - no vehicle radar or LIDAR. The head of Google's autonomous car program is on record as being against V2V systems, because they don't provide reliable data for automatic driving and have the wrong sensors.

If something is going to be required, it should be "smart cruise" anti-collision radar. That's already on many high-end cars and has a good track record. It's really good at eliminating rear-end collisions, and starts braking earlier in other situations such as a car coming out of a cross street. Mercedes did a study once that showed that about half of all collisions are eliminated if braking starts 500ms earlier.

V2V communications should be an extension of vehicle radar. It's possible to send data from one radar to another. Identify-Friend-Foe systems do that, as does TCAS for aircraft. The useful data would be something like "Vehicle N to vehicle M. I see you at range 120m, closing rate 5m/sec, bearing 110 relative. No collision predicted". A reply would be "Vehicle M to vehicle N. I see you at range 120m, closing rate 5m/sec, bearing 205 relative. No collision predicted". That sort of info doesn't involve tracking; it's just what's needed to know what the other cars are doing. It's also independent of GPS. Useful additional info would be "This vehicle is a bus/delivery truck, is stopped, and will probably be moving in 5 seconds.", telling you that the big vehicle ahead is about to move and you don't need to change lanes to go around it.

The whole point was that developers influence the choice of distro on the server

There must be cases where this is true. However, it's really unclear to me why most developers would care and why they would feel themselves qualified if they have competent sysadmins to work with.

When I've got my sysadmin hat on, most of the developers I work with are developing on Macs. They have no hangups about their code being deployed on EL systems in a big data center. Nobody is clamoring for a shelf full of MacPro tubes to deploy on.

When I've got my developer hat on, I usually write on a Fedora machine. But I'm not daft enough to try to run Fedora on a server and have to worry about the maintenance cycle. I put my configs in a puppet module that pushes the code out to whichever VM I'm going to run it on, regardless of the OS, hypervisor, hardware, or country that code is bound for.

If my code doesn't run on a particular distro, then my code is probably broken (or my devops is hosed).

Maybe there are some startups with a bunch of kids and one third-careeer CEO and they all tell him what's going to happen. Good for them, I guess. Someday a sysadmin might come in and help them fix their stack. Let's not speak of the failwhale.

If the US and Europe were to reduce carbon output to post civil war levels (i.e. effectively go back to some sort of agrarian lifestyle), China and India certainly wouldn't be using more coal and oil. It is the US and Europe which is driving the demand for fuel in China. It's not Chinese peasants buying all the stuff China puts out, it's generally the West that's fuelling China's increasing demand.

what's funny is that CS nerds and stats nerds work very hard together to enable hard drive firmwares that permit the very dense and cheap storage that scientists and statisticians need. Not to mention the broad applicability of coding theory to every other discipline. TFA might have a point on the margins but by and large he's trolling academia (which is working to bring attention to his issue).
