Comment Re:Cost of physically implementing SHDSL (Score 1) 234

What will be telling is if they do the same to the DSL customers in the near future as well.

DSL works over high frequencies in existing copper phone lines. Far more physical bandwidth is typically allocated to the downstream than to the upstream. Balancing this out would reduce download speeds in favor of upload speeds. Are you sure implementing SHDSL wouldn't require rolling trucks and mailing modems?

Except Businesses have had access to higher speed symetric DSL for a lot longer; though that's typically a dedicated line instead of one sharing its bandwidth with a voice line.

Comment Re:Why then Netflix didn't deal with Level3 direct (Score 1) 390

Well, NetFlix could also enter into agreements with ever backbone provider, thereby forcing Verizon to either do the same to everyone or start upgrading

This brings to the question of why Netflix has chosen to deal with Verizon instead of with Level3 directly in the first place ?

Even if Netflix didn't know of the existence of Level3 (which I find too ludicrous to be possible) that they had signed up with Verizon, they could have changed the situation right now by dealing directly with Level3, and why wait anymore ?

NetFlix has contracts with lots of folks - Level3 included. These are with respect to pushing content from NetFlix over the backbone into various networks.

NetFlix also promotes having a CDN end-point within an ISP's network to alleviate the need for as much peering; which is what I believe the NetFlix-Verizon deal was about, which Verizon may have (or may not have, we don't really know) charged NetFlix for installing in the datacenters/hubs/central-offices.

However, the fact that NetFlix has done that, which should IMPROVE speed on Verizon's network, and there are still major issues shows that there is something else wrong with Verizon's network. Of course, they might rely on the back bone having sufficient capacity to pull down the information over the CDN too; or it might be that NetFlix installs a direct pipe for the CDNs, we don't know the details. Most likely NetFlix has a contracted pipe with a Level3 interconnect to these, and that is why we're hearing all about it between Level3 and Verizon as Verizon doesn't want to increase their interconnects with Level3 over which those CDN systems are suppose to operate.

But that's just a bit of (educated) guess work as I don't know the details of the Netflix-Verizon arrangement or the network layouts or the NetFlix CDN provisions.

If the mid-1980's is "the old days"...

No. Try the 1930's through the 1970/1980's. It wasn't until the 1960's that things started to filter down enough that you didn't need as much background in to the computer systems, and some where in the 1970's/early-1980's it became what you knew, namely as the micro-computer (aka PC, Macintosh inclusive) took over.

However, prior that - and even during the 1980's in corporate environments - most every programmer had to know a lot about the Electric Engineering of the computer. Most all of them had EE degrees; some had math degrees; a fewer had the new CS degree (started in the 1970's, but not really popular until the 1990's; I think the first CS program was late 1960's, circa 1968).

biggest problem with upload is you send it over free links with Tier 1 networks, or you pay them to take your traffic. with all the user generated stuff now like Twitch, flickr, video calling and other services where you want a fast upload speed that's a lot of data to be paying for.

with the current L3/Verizon dispute i wonder if they struck a deal where verizon will allow the connections to be upgraded for netflix to work on their network in exchange for L3 taking all their uploaded data for free.

Hmm...that actually makes for an interesting case.

So Level3 basically pointed out the issue with User focused ISP's - that they're asymetric and would never provide the ability for those ISPs to compete in the peering arrangements that back-bone providers have. So now if they go to being symetric, it would allow the users to do more and possibly try to combat what the ISP (e.g Verizon) thinks is a fallacy but they can only prove if they make all their links symetric.

Problem for the ISP is users don't really upload a whole lot any way. So it's not going to change anything for a while. It may get Level3 to drop the "symetric vs asymetric" part of their argument, but it won't change the amount of traffic going from the ISP to back-bone provider.

What will be telling is if they do the same to the DSL customers in the near future as well. Otherwise they are still primarily an asymetric provider as they have more DSL than FiOS customers.

Question is: Will Verizon only do this temporarily as part of an argument with Level3? If so, expect a change in the future when their plan doesn't work out. If not, then hopefully other ISPs will follow in order to "compete".

Comment Regulation won't stop them... (Score 1) 435

Honestly, the fact that they are even available for testing means that some criminals will use them, even if they are outlawed.
As to the specific points raised:

It discussed issues such as letting criminals shoot while the car drives (silly in my opinion, apparently they haven't heard of "partners" or considered requiring such cars have a police controlled "slow down" command),

Slow down command won't mean a thing when the criminals rip out the necessary parts to make it moot or reprogram it to do something - ignore the command, do the opposite, or even blow up the vehicle.

the use of such vehicles as guided bullets (safeties again should stop this), and loading it with explosives and using it as a guided missile. This last concern is the only one that I considered a real issue, but even that is not significantly more dangerous than loading up a regular van full of explosives with a timer, then setting the timer to explode before you leave the vehicle next to a school, etc.

True, aside from it being a "guided" missile - just set a target in the GPS and off it goes....again, the potential is there and criminals won't allow it to stop just because of a "slow down" or "stop" command. They'll figure out a way to override that before using it.

And again, if they really wanted to do it the technology is already out there and nothing is going to stop them from using it if they really wanted to.

Software engineering has a tendency to enshrine ivory tower principles, that - although sound and logical, can end up making your project large, slow bloated and excessively encapsulated. I'm happy that NASA and the DoD both use it, those things need to be rock solid, but it just doesn't make sense for a lot of businesses where being first to market is more important than any code refactoring issues you might have 2 years down the track. Being slow to market might mean you don't even have a business 12 months from now.

Good programmers know when to lay on the engineering and when to pull out the stops and slap something together that does the job "just good enough". That's part of what makes it an art, not a science.

NASA/DoD does a form of Software Engineering based on Engineering principles from other disciplines, namely mechanical and electrical engineering. Much of what they do there doesn't really apply to Software.

What we need to do is define Software Engineering in a manner that is practical for everyone to do it such that no one has any kind of excuse not to do it. To me, it's a matter of doing software in a very discipined manner and has nothing to do with whether you've documented every function at 30 different layers for 10 different stake holders across 5 different organizations.

You don't need to have an engineering degree to write a price of software that implements calculations and algorithms that are needed for an engineering project. Programmers turn math, algorithms, business methods, ideas and the like into code. That's our skill, understanding your needs and expressing it in a way a computer can understand.

I was just noting the irony. That said, I would personally put forward that people doing programming in the real world need a software engineering degree, not a computer science degree as you don't do computer science when writing real-world applications - you apply the principles of Computer Science in an disciplined/engineering methodology.

But then, software engineering as a discipline is in such poor shape that it is not really helpful to anyone but NASA and DOD as currently defined, and that needs to change.

The problem domain isn't "monitoring plants with only an AA battery for power" though. It's a host capable of running Linux and assorted toolchains for embedded software development. I know that there are systems for all kinds of applications and the power envelopes they prescribe. That's not the issue. The issue is that someone proclaimed that "electricity is expensive. Douche bag." And that's not true. Electricity is cheap. Cheaper than hardware which is incredibly cheap itself. And that holds true even for the very low end, where a tiny amount of energy is sold in an expensive package, but a finished system will still cost more than the batteries it takes to run it for a couple of years before it is replaced, yet the hardware is sold at prices which almost make the devices disposable. For perspective: How many smartphones does the average person buy per year? Still think a low to mid range quad core desktop system is expensive?

So I do development and I want to cut my costs down. I presently have a desktop at home with a 600W supply and a server with a 250W supply, as well as laptops with 60-90W supplies. As I use the desktop for other things (e.g playing DVDs, Netflix, etc.) I'm satisfied to leave it for now; laptops might get replaced by tablets or chromebooks.

But the server? I keep it on a UPS, and would love to be able to keep it up for a very long time. On the UPS it would only get between 10-30 minutes if power fails (APC 1500). I am very interested in switching it out for a few lower power devices. In fact, I'm targetting replacing it with 3 devices (a Rasberry Pi for authentication, a Udoo for disk storage, and a Routerboard for firewall support) with a total power envelope of 50W.

Do I still intend to do software development on the server? Yes.
Do I still intend to do DNS, DHCP, Samba, WebServers, etc on the server? Yes.

But you know what - unless I'm building something targetting a mainframe, some heavy video driven application (e.g games, autocad, etc) then I really don't need a very powerful system. Point being - a beagleboard, Udoo, or Rasberry Pi really is sufficient for most people doing software development....well, unless you're trying to use Eclipse or Visual Studios, but then you're just asking for trouble.

Why? A Civic Engineer doesn't design skyscapers. They decide only where the skyscapers can go and make sure the location can support it.

It's the structural engineer that designs the skyscaper based on the concepts from the architectural engineer that the client wanted to put in the space that the civic engineer told them they had on the land they own.

Of course, all of this was done in software designed by people without any engineering experience at all...go figure.

Somebody didn't read the article:

"In the old days there was a respected profession of application programming. There was a minority of elite system programmers who built infrastructure and tools that empowered the majority of application programmers.

I think this is more of deluded statement than anything. In the old days you typically had to have an Electrical Engineering degree to do programming - at a time when having a college degree was not the norm. This only filtered out of that circle as geeks took interest before college and tools became easier and costs were greatly reduced. The point: programming has always been done by a small group - the "elite" - at any time in the history of computer systems.

Our goal was to allow regular people without extensive training to easily and quickly build useful software. This was the spirit of languages like COBOL, Visual Basic, and HyperCard. Elegant tools for a more civilized age. Before the dark times before the web."

Again, progress has certainly occurred towards this, but the fact of the matter is that most people are not interested in being creative the way programming requires you to be. They'll be happy to play around with HyperCard or Excel long enough to get some basic thing done, but they'll be atleast equally happy to pass it on to some one so they can focus on what their actual job in stead of trying to figure out how to make a fancy little graph.

"The web is just an enormous stack of kluges upon hacks upon misbegotten designs. This Archaeology of Errors is no place for the application programmers of old: it takes a skilled programmer with years of experience just to build simple applications on today’s web. What a waste. Twenty years of expediency has led the web into a technical debt crisis."

Many of those things are because of people not skilled enough making the decisions - not understanding what's there and trying to fix it, only to realize later when they do understand it better that they royally screwed it up.

I don't think you understand how schools and their curriculae work. Nobody is holding a gun to the collective and independently-operated heads of CS departments to demand which language they use for beginner courses.

Java was historically chosen because it was a safe option; used widely in industry, decent documentation and tools, it supports good programming practices, and it provides reasonably powerful options while being relatively beginner friendly. Java largely replaced C and C++, which are not beginner friendly.

Funny...Java only lasted may be 10 years as the "first" language for CS curriculae. C++ laster longer (15+ years), and C longer than that.

Now unlike with C and C++ they did find bigger issues with Java being the first course - as upper level classes (e.g Networking) found they had to teach kids C/C++ first before they could get into the course material. Not to say that won't still be an issue with Python...it'll probably have its own layer of issues.

Needless to say, if I had to learn programming my freshman year of college I would rather have had Python than Java. (I didn't; I learned to program in High School in a far superior manner than taught at the college level; but that's beside the point here.)

That's not how it works at all.

Airliners pretty much since the jet age have had at least some measure of "envelope protection". In the 60s this was pretty simple - just a stick pusher to prevent stalls since stalls in many airliners can easily become unrecoverable. Airbus's envelope protection is much more sophisticated than just a stick pusher.

However when there's a systems failure the Airbus systems will automatically drop to a different control law that effectively works like basic stick and rudder flying.

So if the system is working perfectly fine, but the pilot wants to do something that the system thinks the pilot shouldn't do, then who gets to determine the end result? What if doing what the system wanted to do would lead to the system having an issue? Or if the system did not detect that one of its sensors (and the backups) had degraded because they all failed the same way?

There are a million scenarios where the system thinks it is right and the pilot knows the system is wrong but needs to do something else. Time matters in all scenarios where the plane may be in trouble.

Boeing uses fly by wire now too by the way.

Beoing may be fly-by-wire, but there is a difference between fly-by-wire and pilot vs computer being in control. You can design fly-by-wire such that the pilot still has the last say in the matter without having to have the system enter into a degraded mode first.
