He's implying that developers will specify a complete environment where every DLL available to the application within the environment is exactly what the developer used. There is no DLL hell because you run what the developer ran, and it doesn't matter if you have seventeen different incompatible versions of (to pick windows example everyone's familiar with) mfc42.dll, because things inside the container won't know that you have those dlls.

In that case, why bother with dynamic linking at all? Why not statically link everything? The effect is essentially the same -- you get exactly what the developer had. You also get no shared code pages -- even if you're using exactly the same library as someone else -- and bloated memory and disk usage since you have your own private copy of everything. Disk may be "cheap," but it's still surprisingly easy to fill up a 16GB eMMC device.

Am I getting hopelessly old and unable to appreciate new things, or is this not anywhere near as whoop-de-doo as they're making out?

"You can update transactionally!!" Great. What does that mean? Is it like git add newapp; git commit -a? If so, how do I back out a program I installed three installations ago?

Transactional updates have lots of useful properties: if they are done well, you can know EXACTLY what's running on a particular system, [ ... ]

dpkg -l

You can roll updates back, [ ... ]

dpkg -i <previous_version>

...lets you choose exactly the capabilities you want for yourself, rather than having someone else force you to use a particular tool.

#include <cheap_shots/systemd.h>

Because there is a single repository of frameworks and packages, and each of them has a digital fingerprint that cannot be faked, two people on opposite ends of the world can compare their systems and know that they are running exactly the same versions of the system and apps.


Developers of snappy apps get much more freedom to bundle the exact versions of libraries that they want to use with their apps.

...Did this guy just say he brought DLL Hell to Linux? Help me to understand how he didn't just say that.

I bet the average system on the cloud ends up with about three packages installed, total! Try this sort of output:

$ snappy info
release: ubuntu-core/devel
frameworks: docker, panamax
apps: owncloud

That's much easier to manage and reason about at scale.

No, it isn't!! What the hell is OwnCloud pulling in? What's it using as an HTTP server? As an SSL/TLS stack? Is it the one with the Heartbleed bug, the POODLE bug, or some new bug kluged in by the app vendor to add some pet feature that was rejected from upstream because it was plainly stupid?

Honestly, I'm really not getting this. It just sounds like they created a pile of tools that lets "cloud" administrators be supremely lazy. What am I missing here?

I worked for NTG/3DO for just under five years, so I know (knew) the machine inside and out. It will be interesting to go through this code and see what kind of tradeoffs were made.

Some comments on the README:

My friends at 3DO were begging for DOOM to be on their platform and with christmas 1995 coming soon (I took this job in August of 1995, with a mid October golden master date), I literally lived in my office, only taking breaks to take a nap and got this port completed.

*snerk* I could have told you at the time that a ten-week dev cycle was crazy talk.

Shortcuts made...

3DO's operating system was designed around running an app and purging, there was numerous bugs caused by memory leaks. So when I wanted to load the Logicware and id software logos on startup, the 3DO leaked the memory so to solve that, I created two apps, one to draw the 3do logo and the other to show the logicware logo. After they executed, they were purged from memory and the main game could run without loss of memory.

An interesting and valid approach (3DO's OS had full memory tracking). I'd be interested to know which of the 3DO libs was leaking memory on you.

The verticle walls were drawn with strips using the cell engine. However, the cell engine can't handle 3D perspective so the floors and ceilings were drawn with software rendering. I simply ran out of time to translate the code to use the cell engine because the implementation I had caused texture tearing.

Were the floor/ceiling textures not power-of-two dimensions on each side? As I recall, you only got texture cracking when the dimensions were not power-of-two.

You could have decomposed the floor/ceiling textures into strips as well, but ultimately the lack of perspective correction meant you were going to have to do some heavy lifting somewhere.

I had to write my own string.h ANSI C library because the one 3DO supplied with their compiler had bugs! string.h??? How can you screw that up!?!?! They did! I spent a day writing all of the functions I needed in ARM 6 assembly.

Ah, yes, the Norcroft compiler (or, as I always called it, Norcruft). It was a piece of shit. It was also the only thing available that would run on the Mac. It was never anything but a C compiler, but kept throwing unblockable warnings about constructs that C++ would have problems with (such as implicit cast from void*). There was no MacOS port of GCC, and there were no usable ARM backends for GCC available at the time, anyway. (Bear in mind, this was before the Web existed in any familiar form, and you had to go trawling through USENET for clues -- not even AltaVista existed yet).

I hope that everyone who looks at this code, learns something from it, and I'd be happy to answer questions about the hell I went through to make this game. I only wished I had more time to actually polish this back in 1995 so instead of being the worst port of DOOM, it would have been the best one.

I'm sure many memories will come flooding back.

And, if you've not figured out what I'm trying to tell you, my answer in your example would be, "Unless you want to spend two more million and spend 12 more months in development, and COMMIT to that- no."

The idiot notion of not being "negative" is fantasy that some crazy HR people came up with to whitewash over the real problems going on in a given company. You need to not just simply say, "no", but in the same vein, trying to not say no is stupid, crazy, etc. Sometimes things ***ARE*** really negative things and you can't wish/will them any other way.

The problem with that particular notion ("Yes, but you'd need to spend...") is that they're oftentimes NOT savvy enough to grok where you're coming from and they'll just hear the "yes" and make you try to jam 18+ months of dev effort into 6-8 months with the typical, classical, predictable failures, in spite of explanations why it just won't work with their notion. They hear "yes" followed by "wah...wah-wah...wah-wah-wah" like on Peanuts animated features when the adults talked. The "yes" means to them it's doable- the rest is irrelevant details as far as they're concerned (And, YES, I've dealt with the kind all too often and quite a bit in the last two and a half years, much to my chagrin...)

If "yes" is part of the answer when it probably ought to be a "no" or a qualified "no", then it's the wrong answer many times. Seriously. Any notions, from HR or otherwise that doesn't allow for a "no" answer from anyone other than executive management is a recipe for disaster.

They saw the cookie-cutter AS degree and passed on him. Not broad-based enough. Probably in a downturn.

Both items are deal-breakers when you're dealing with someone with the levels of experience that were available during the latter condition. (Why get a fresh AS grad, when you can get an SME for roughly the same price? Mainly because the SME's desperate...)

Yeah, you're technically old-school. You were taught a discipline- which, in truth, is little different than learning a trade, to be bluntly honest.

Colleges have lost their way...or worse, they've taken to strip-mining students for all the cash they can bleed from them and the government through student loans.

How many of them are doing embedded Linux and Android projects- and when they weren't, how many of them were using ThreadX, VxWorks, pSOS, Lynx, QNX, etc.?

If you needed to know VS, you were working in the wrong circles. I didn't need to know VS even though it was one of the bigger deals for doing Windows development- I knew how to code C++ and understood and used ATL, MFC, etc. Which, by the way, is the way everyone should've framed it. Not, "do you do VS"?

Which is pathetic for the CC, honestly. Python's doable because it's *free* just like Java was then- and worse, you didn't need VS to do C++...

Dev C++
With MinGW or Cygwin, Eclipse

Sure, it didn't have some of the glitzy stuff MS was shovelling- but you could have pretty much done Windows or Cross-Platform C++ development back when Java was the big rage at the Community Colleges. And this doesn't even get into them doing Linux for all of it, including Java, Python, etc... They're guilty of some of the same mentality that spawned the notion that these idiot "bootcamps" are a good substitute for a discipline or vocational education. The problem isn't quite the thing Mike Rowe's fingering on this- but he's close enough to not disagree at all. They're guilty of trying to strip-mine all the students for all the money they can. Actually teach something? That's too much into our "BoM" on those grads we're pumping out.

Part of the reason you had problems getting a gig was that they saw the "cookie-cutter" Associate's degree and passed on that. You've nothing to offer except coding for them at that stage, regardless of whether that's true or not- because that's the only metric they've got to go off of. If you actually have ability and can pick up the Engineer's trade, you should get the rest of the BS degree you should get (which won't assure you the job...little will, honestly, unless you've got 2-3 decades of the bleeding edge, self-taught through the school of hard knocks...but it'll HELP, all the same...) and work on teaching yourself any gaps in anything they didn't teach you on your own. There's always something that they won't/don't teach you. You have to learn it on your own. Whether it's C++, OOD/OOA, or the like, you're going to have to be able to grab the ring yourself repeatedly to keep employed. The reason they passed on you is the AS degree- because of the "pathetic" I opined on at the beginning. They're not teaching a trade. They're honestly not teaching a good base to work with at most Community Colleges these days. They're teaching you the in-vogue stuff right then (You shouldn't be learning VS, you should be learning C++ which doesn't really and honestly give a tinker's damn where it's being implemented if you've done it right... You shouldn't be learning Java just because the College is too cheap to get proper Windows tools (which, again, is PATHETIC because the tools have been "there" within reach for nearly 20 years...). You shouldn't be learning Python because that's the big main big-deal in dynamic content websites in there with Java and PHP... You get the idea...) In all honesty, it wouldn't endear you to me if I were to hire help with either my Game Porting interest or my Agritech one. In the former, I'd need a self-starter that understands C and C++. They'd need to be adaptable to pick up Lua if they didn't already know it. They'd have to be able to debug code on X86, ARM, and MIPS. The requirements for the Agritech business I'm starting...are similar in nature, along with "getting" embedded coding. That's the kinds of jobs there's currently work for that's sustainable. An Associate's isn't going to help you there unless you can show you putz with that stuff already and can prove you might grow to fill those shoes in a 6-18 month timeframe being allowed to do it. The same goes for a "bootcamp".

And, unless they were wired to move on to other things, either on their own or by way of a proper (mind...) college education, they'll be technically obsolescent in 3-5 years.

Bootcamps are useful for teaching you some new buzzword skill, but they're not the same thing as properly learning a trade or a discipline- they're only truthfully useful for quickly picking up a new set of tools for the trade.

I wouldn't put mine to the curb because I'm still playing game titles on the console. Having said this, the world being awash in $100 and less boxes that do a better job of Netflix (AND the others...), it's also awash with devices that with a decent BT game controller or similar can manage just shy of the PS3 titles as well.

It's not a wise move on their part. Google's going to eat their lunch if they do this.

It's still a hack and a workaround there. Just because it works "okay" and it's "easy" doesn't mean the yanking of the functionality in the PS4 isn't problematic. I know I'm waiting for a critical mass of PS4 titles before I contemplate a move- and with GoogleTV or an Android HDMI stick, it became stupidly easy to do the others. It's another box, but still- Sony's not getting me to sign off on this crap and at the rate they're going I might just give the PS4 a pass as well.
