Education. Engineers get the engineering core education. Which is basically calculus, physics, diffEq and the first semester of all the engineering disciplines (more or less the first two years of a four year program). Only then do you start your specialized education.

Competence not guaranteed in ether case. Engineer job title means nothing.

Degree from certified engineering school is the requirement for an 'engineering' degree. 'Engineering technologist' is the weasel word version from shitty schools.

Some nations require that you pass the P.E. test (or it's local equivalent) to call yourself an engineer, some that you are qualified to take the E.I.T.

In America anybody can call themselves an Engineer.

Wrong. That is only the case with Software Engineeres, and even then if you are in Texas you have to pass a certification to do so.

In pretty much every other Engineering field you cannot call yourself an Engineer without first having passed the exams. Just like you can't call yourself a Lawyer (Esquire), CFA, CPA, or a number of other titles without passing the relevant exams either.

And the difference between engineer and developer is.. what?

Engineers are often held personally liable for their mistakes. Tim S.

Only one state (Texas) regulates "Software Engineers". Software Engineering is perhaps the only Engineering field that that statement doesn't apply to except, perhaps, in Texas (but even then I doubt it). Typically "Software Engineer" is synonymous with "Software Developer".

On the other hand, a "Computer Engineer" is regulated in all states since it is a sub-field of Eletrical Engineering.

My CS professor said you can only get a CS job these days with one of them, but I can't find any information on what I have to do to get certified.

Get a job where a company will sponsor your H1-B visa. You can't apply until you have a job. The company has to justify the need to hire you over someone else for it to be approved.

If you believe yourself to be an eternal being, then this life is but one small step in a much longer journey. It's always puzzled me why so many Christians fear death, when they claim to know they are going to a place vastly superior to this one.

Well, there are many who profess to be Christians but are not; but then, you always fear what you do not know, no matter how much you try.

And then, of course, many fear how death will come on them - do you really want to die because a sword cut off your head in one of many passes, being burned alive, etc?

What kind of idiot would buy a cell phone with a non-replaceable battery? That would be even more stupid than if it had a proprietary data-cable port. Nobody in their right mind would but such a crippled device.

Apple Customers....did you see the original iPod? They've never had replaceable batteries. Now others (f.e. Google) are following with their high-end lines (Nexus since Nexus5 phone and Nexus 7 tablet).

What If We Lost the Sky? 420

HughPickens.com (3830033) writes "Anna North writes in the NYT that a report released last week by the National Research Council calls for research into reversing climate change through a process called albedo modification: reflecting sunlight away from earth by, for instance, spraying aerosols into the atmosphere. But such a process could, some say, change the appearance of the sky — and that in turn could affect everything from our physical health to the way we see ourselves. "You'd get whiter skies. People wouldn't have blue skies anymore." says Alan Robock. "Astronomers wouldn't be happy, because you'd have a cloud up there permanently. It'd be hard to see the Milky Way anymore."

According to Dacher Keltner, a psychology professor at the University of California, losing the night sky would have big consequences. "When you go outside, and you walk in a beautiful setting, and you just feel not only uplifted but you just feel stronger. There's clearly a neurophysiological basis for that," says Keltner, adding that looking up at a starry sky provides "almost a prototypical awe experience," an opportunity to feel "that you are small and modest and part of something vast." If we lose the night sky "we lose something precious and sacred." "We're finding in our lab that the experience of awe gets you to feel connected to something larger than yourself, see the humanity in other people," says Paul K. Piff. "In many ways it's kind of an antidote to narcissism." And the sky is one of the few sources of that experience that's available to almost everybody: "Not everyone has access to the ocean or giant trees, or the Grand Canyon, but we certainly all live beneath the night sky."

Alan Robock says one possible upside of adding aerosols could be beautiful red and yellow sunsets as "the yellow and red colors reflect off the bottom of this cloud." Robock recommends more research into albedo modification: "If people ever are tempted to do this, I want them to have a lot of information about what the potential benefits and risks would be so they can make an informed decision. Dr. Abdalati says deploying something like albedo modification is a last-ditch effort. "We've gotten ourselves into a climate mess. The fact that we're even talking about these kinds of things is indicative of that."

A friend of mine suggested such an idea to me 15 years ago. This is what I told him.

You run it inside an x86 interpreter which simulates the CPU all the way through the decryption. Then you snapshot the decrypted code and rebuild the app without the decryption and substitute the decrypted code. Now it's just a plain app. If it tries to "detect it's environment" (read the clock, etc), the simulator just tells it whatever it wants to hear. It cannot know it's being simulated, it's just code.

In a sense, that is exactly what Bochs is. It's a true Virtual Machine in that it software interprets every CPU instruction, and emulates every piece of connected hardware - RAM, motherboard, video, network, usb, chipsets, etc - to do so. A truely fine tool for OS and hardware developers.

Yep that trick totally evaded me... I don't doubt that would work fine though. Now.. what about if it had to be connected to the internet to validate the installation at startup >:W And the server had to give it's response in a reasonable amount of time ie 100ms and you couldn't fake it on the PC due to encryption. Now I don't doubt that could be broken but it would be a tad harder at least perhaps ... maybe :D

Until you have someone that has a slow internet connection, f.e sat-com where latencies are typically around 500ms or worse. A poor network, or bad mix of equipment, can make latencies really bad even on an otherwise good network.

For example, my Dell D600 from 2003 had a Broadcom networking chipset in it. The 1GBit interface had a problem with some Cisco routers. The previous routers it was on were 10/100 and it had no issue; but when they upgraded the router to 10/100/1000 the new router had an issue with the auto-negotiation. Until I figured that out, the network speed when from 100 megaibts to 17 kilobits. Outlook generally worked okay (no choice at that company) but anything that made more use of the network had big issues. (Outlook worked to view what was in my inbox, because of the small messages; but even then it was slow).

So even doing something like that would be risky - of course, you could also just capture the network traffic and hack that too; since you can control the network in Bochs, if you were really going that far it wouldn't be an issue to capture and adjust it as required to make it think it was talking to the real thing. This is actually relatively easy:

  1. Setup a transparent MITM proxy so SSL connections can be handled and neither side necessarily knows about it; though they would have to allow you to specify a client proxy because some places require you to do so to get to the Internet any how, so you could just use a client proxy too.
  2. capture the network traffic using tools like Wireshark for several different runs of the program
  3. compare the deltas to figure out what is changing

Now you just setup a server to either play back the captured data, making the emulated system think it is running at that point when the older software did, or if you figured out enough of the traffic setup something to fake the other side in a way you control.

FYI - this is how SaMBa got started (at least for Windows compatibility) - network analysis of CIFS/SMB traffic with Windows. They found some interesting things doing so - read their docs for things like single-bit flip reboots the Windows computer kind of stuff.

There's very little that cannot be cracked in this regard.

That's utterly ridiculous. There's a lot more to an OS than just the desktop environment (DE): there's the kernel, the init system and other low-level daemons, the display subsystem, the package manager, and of course lots of apps (beyond just what KDE (or Gnome) include in their software collections). The KDE team has enough work to do, they certainly don't want to become their own distro, when there's already several distros that feature KDE as a prominent DE (Mint, Debian, OpenSUSE for starters).

You do realize that KDE is maintained on more than just Linux - including BSDs, Unix, Mac, and even *gasp* Windows. Some ports (like the Windows port) are not as far along as the others - well, pretty much just the Windows port last I checked, and that's primarily because of Windows not having some of the requisite functionality yet.

I'd avoid SVN for anything that isn't a flat text file, otherwise it becomes a pain to merge or determine what the actual difference between two files is. I'm not aware of anything that will make viewing diffs for Word documents human readable. Never mind that some of the people who need to use it will probably be a afraid of it or have even more basic problems like forgetting to commit.

Which is why you just treat the SVN repository as a WebDAV network drive. They user knows nothing about the underlying versioning going on, and you can always capture back the old version.

Additionally, tools like TortoiseSVN (well, technical TortoiseMerge written by the TSVN devs) have support for comparing MS Office documents. You have to have MS Office installed as it loads both into MS Office and runs the comparison functionality within MS Office to do the diffs.

Most developer VCS are overkill for a business environment. Do you really want to have to explain branching/merging or *gasp* rebasing to an office temp? The ideal system would require initial configuration and then create versions automatically.

Candidates: * Dropbox or equivalent. Good choice. Automatic backup and versioning. Reasonable per user / month pricing ($15/user/mo) * Sharepoint. Love it or leave it.

Individual users can turn on the versioning features of office, but since no way to enforce that behavior, good luck.

http://www.makeuseof.com/tag/not-just-for-coders-top-version-control-systems-for-writers/

That is why I usually recommend Subversion - because you can just mount Subversion like a network drive since it uses WebDAV as its base protocol. I've done that with several managers and it works well.

And there's no additional cost.

The problem now, though, is that Microsoft is removing their WebDAV FS drivers from Windows.

Just detect if CPU performance is above a certain threshold.... Bochs is slow dead slow as is anything else that emulates adequately enough to make this vector of attach relevant even FPU x86 cpus are at 486 performance levels these days.

Until you adjust the base clock so that the software running under bochs thinks it is running at 1GHz while in reality it may be running at 1 instruction per minute. Yes - it's possible to do since Bochs doesn't rely on host system for any hardware, unless you introduce the qemu module for Linux to bring it to near native speeds but someone employing this kind of reverse engineering wouldn't want to do so.

This is possible because Bochs is a 100% software emulated computer. They emulate everything, and even have their own motherboard and video card (VGA) BIOS stacks.

The more they over-think the plumbing the easier it is to stop up the drain.
