  1. Why I would be really happy about this on Mind Control In Virtual Reality, Circa 2013 · · Score: 1

    Amazing! A friend of mine has done his Ph.D. in exactly this field. He was shining a beam of light right THROUGH an opaque sheet of material (paper, I think) already a few years ago, and published about it in 2008. I think it's pretty much the same idea, from what I understand of it (but keep in mind, I chose the evil path of Business instead of Science, so I have no brain).

    Anyway; on his page there's a much better explanation, with cute pictures and all that, of the same idea.

  4. Chrome does not need market share on Google's Chrome Declining In Popularity · · Score: 2, Informative

    Google did not build Chrome to capture market share. They did not create it to launch a product or to circumvent adblock (duh).

    They built it for a real strategic reason: to make sure the web remains usable and open. If Google hopes to serve web apps in the future, they depend on the quality of browsers, and the current browser architectures apparently don't satisfy them.

    Changing Firefox wasn't an option and attacking IE is a mission with very little payoff for Google. So Google chose to inject their design principles into the market by creating a radically new, yet incomplete browser, and release it open source, so it gets adopted. If Microsoft steals this technology to make IE9 even better, Google's mission will have succeeded.

    There's an Economist article which explains all this pretty good as well:

  5. Be more specific on Ethics In IT · · Score: 1

    Hello,

    Speaking from experience (I work in IT, I did an MBA, I chose the elective Business Ethics, I had to write an essay), my first guess is that your prof will tell you to be MORE SPECIFIC.

    Do a google for, for instance, the Journal of Business Ethics ( http://www.springer.com/philosophy/ethics/journal/10551 ), and be surprised by the wealth of articles you'll already find about a really wide range of Ethics & IT topics. At the same time, once you have read the first few, you'll notice how immensely full of holes this area of research actually is. There's academic articles, for instance, about the morality of P2P File Sharing in Asia or the limitations that virtual personae should have with regards to knowing what they should remember about a given system. There's professors specialising in the combination of Business Ethics & IT; Jeroen van den Hoven (University of Delft) is the first one that jumps to mind for me.

    So, if you wish to add something to this body of existing knowledge, you'd either go with something very specific (i.e. the behavior or a normal user when suddenly granted god access, on a tuesday afternoon, if he's exactly 42 years and two days old) and search what else has been written about your specific topic, OR you could do what your initial suggestion is, and give a high-level overview of a given topic. If you prefer the latter, the least that will probably be required is a quick overview of which topics are covered in research and which are currently barren. Summing up best practices or drawing up a directory of "hey, this is what slashdot users think" may be valuable, but only if you put it into a good context.

    Hope this helps :-)

    No it doesn't "closely mirror the technal functionality" of the internet. It may seem like it to the user, but cells are nothing like backbones. Technically there are few similarities.
    This is arguable. Except for the bearer medium and the connection-oriented principle of phone-to-GGSN, 3G technologies like UMTS have a routed IP backbone at the core of it just like a "traditional data" network does.
    Because a cell phone has a two inch screen. DUH.
    I'm seeing loads of people on the subway and at the airport that use PDA's which function on cell-phone technology, and use this "two inch screen" to browse the 'net. In fact, while I was on safari in South Africa we kept track of the worldcup scores by using a GPRS-enabled PDA to browse to a website that provided us with the scores in real time. Keep in mind that this website was owned and operated by the cell phone operator since we apparently couldn't get to fifa.org. Web-on-the-go may have been useless a few years ago, but ever since European providers advertise with a picture of Google on their PDA's I think the world is ready for a mobile ebay/craigslist/etc.
  9. What's the alternative? on Cell Phones Presage Future of Non-Neutral Internet · · Score: 2, Insightful

    So, no net neutrality is a bad thing - I've felt this in my guts for a long time and this article gives me some very good arguments to articulate it (yes, I should have done my own thinking, but I'm lazy).

    It's easy to understand WHY cell phone companies are doing this, though. Too much money was lost in creating a transparent, neutral internet; some companies and executives may have gotten rich but as an industry, global telecommunications has an appaling performance record.

    Cell phone providers are one of the potential providers of the "next net" (depending on who will win the technology battle - the cell phone providers with 3g/4g, broadband providers with WiMax or whoever else can float a business model for some cool technology). So, the folks in strategy and marketing of Verizon/AT&T/ have figured that net neutrality is a bad thing 'coz they need to get some ROE on their investor's buck.

    The question is - how are we as consumers (or better - potential entrepreneurs?) going to prevent this from happening? I'm not sure Joe Average is smart enough to understand he shouldn't be buying his UMTS minutes from a company that doesn't offer him a neutral service.

  10. Been on both sides. on Is Corporate Speak Invading Your IT Department? · · Score: 3, Insightful

    Well... I guess I am in the position to comment on this one. Depending on your viewpoint, I may be a corporate sell-out, a nerd without spine or just someone who goes where the challenge is.

    I'm a CCIE, so I have at least some credibility in the tech department. I spent years working on some of the most interesting projects a CCIE could dream of - network planning, (re)design, troubleshooting, working with Cisco and other vendors to develop next generation features... Yeah, it was interesting and 98% tech-related. After a few years, though, I kind of lost interest. I found that the "next generation" complex system after BGP wasn't RPSLng but instead systems of people. Once you get the RFC, working with the system is simply a derivative. However, there's no RFC for "how companies work" - and there are so many more facets to understanding the system of how people work within a company than within even the most complex network. Maybe it's different if you program java, but for me, I found the interesting challenge elsewhere.

    Most of us wonder why the heck our stupid managers make some of the decisions they do. Yes, maybe they are plain stupid. Maybe, though, "they" understand something that we do not - and I wasn't going to let the arrogance of "knowing better because I am a geek" tell me that managers are stupid. I wanted to find out what made them tick.

    I am now enrolled in a part-time MBA program at a good institution (and recently recertified for two more years of CCIE-dom while doing it). I've had a job as a "pre-sales consultant" so I could begin to understand how this whole evil sales process actually takes place. I've always wondered why someone with money to spare would give it to someone who, to us geeks, obviously has so little brain as a sales guy.

    No, the answer is not that people with money to spare are by definition stupid. The answer is not that sales people are necessarily shallow. The answer is not that earning money is evil. The answer from the IT department should not be "I READ YOUR EMAIL! FEAR ME!", as this is probably the best excuse I can think of to recommend outsourcing to the next CIO I meet.

    I'm now at the point where I have taken up a relatively new concept within my company and can make it work partially because I understand the technological concepts underlying it AND because I can explain to companies why it is important for them to invest in my concept. This requires me to speak some of the lingo - and yes, I do talk about adding value to a company's core business processes with the use of our business solution. I talk about the benefits of RFID for supply chain management. I wear an expensive suit and describe the opportunity for growth in a certain market which can be enabled by this-or-that network solution. So, yes, the 'speak' is important if you want those who are likely to make decisions to hear you.

    However, having said that, the 'catch' is that there is a lot of BS going around in the corporate-speak-world. If you discuss a routing protocol, there can be no dispute - in the end, look up the RFC or reproduce whatever you're trying to prove. Discussing a company's marketing strategy or trying to make a business case for unified messaging is a lot more shaky. There's no undisputable book or testlab to point to and say "look, you're wrong, see - that's not how it works!". I can quote the latest book or article I read about the latest trend in strategy. I blurt out page numbers of Harvard Business Review articles. This is not proof, though. The guy to which I am talking can always blurt out some Sloan Managment Review article which declares exactly the opposite. Or worse, he will pretend to know it better - and he just might. There's no way to prove it. Professors have been wrong - unlike a routing protocol, which just "is".

    This is exactly why corporate BS'ers get away with BS'ing - and why it's so difficult for most of us with a technical background to work with a system that apparently allows tolerance for nonsense.

  11. Image-building or not-doing-evil? on Google.org to Spend an Initial $1.1 Billion · · Score: 1

    I am a huge fan of companies becoming involved in charity. The practice is mostly dubbed "corporate social responsibility" nowadays - see http://en.wikipedia.org/wiki/Corporate_social_resp onsibility

    I also honestly believe that a company with a real long-term vision will understand what CSR means and will therefore act accordingly to it. Most Japan-based companies realise that there are 120 million Japanese on a small island, and that it doesn't take too much to upset the local eco-system. Factories and plants are almost by rule CO2-neutral. Couple this with the long-term vision that is inherent to the Japanese and you understand why Toyota was the first company to shoot for the "green car". It's not just caring about the environment - it's business. I have even been at seminars where consultants calculate the price of media coverage gained from "philantrophic" activities. Yes, these activities definately CAN have a good ROI.

    However, I do think we have to realise that 98% of companies are active in CSR because it is a short-term economic response. Individuals are becoming slightly more moral, and they expect the same from the companies they are doing business with. Nike can't exploit little kids in far-off countries anymore, and
    since Brent Spar, Shell can't sink end-of-life drill platforms anymore (nevermind that the Shell scientists were actually right in this case...). Other companies have to follow until in ten years, CSR is a requirement and not a differentiator.

    So, we therefore have to ask ourselves. Is Google buying $1.1b of brand equity - hoping to reclaim the "coolness" they lost over google.cn? Or does the $1.1b really spring from their true desire not to do evil? Yes, the effect will be the same. Their motives, however, are what determine if they would still act like this if there's no shareholder-driven imperative anymore.

    Two good writers come to mind. I've named both of them because they evolve; other then, say, Orson Scott Card who just writes the same 4 books about 15 times, these guys grow from one stage into the next:

    1. Neal Stephenson. "Snow Crash" and "The Diamond Age" are probably the only ones of his books that could be classified as "Science Fiction". They all succeed in mixing a number of themes into a reasonably good story. In the case of Snow Crash, he's trying to mix mythology with technocracy and linguism. In his last work, "Cryptonomicon", he's completely stepped off of SF and is proudly banging himself on the chest about the research he did into the WW2-history of cryptology (it's still a good book, though).

    2. William Gibson. Writing mostly in trilogies (two so far), his most famous book being the first one of the first trilogy - Neuromancer. It's cyberbunk at its best, but over the books, he's turning into a stylist rather then a technogadget-loving society-critic (how's that for scrabble-words).

  23. Try networking... a sidestep can renew the feeling on What Do You Do When CS Isn't Fun Any More? · · Score: 1

    I was in exactly the same situation. Four years of "computer engineering", at a crappy university years behind the times, trying to teach me how to integrate software with hardware.

    I was sick and tired of it by the end of year 1, even though all I had wanted as a kid was to do "something with computers". But after the first few years, I got so fed up with the way it was taught and the uselessness of the education that I had a severe case of antipathy against anything CS-related.

    Then my first internship. Bay Networks. For some freakish reason it was a networking assignment, not in the line of computer science 'pur sang' or even computer science. I learned the wonderful world of IP, routing, switching, ATM, Ethernet, Token Ring, , all the beautiful stuff that didn't have their roots in CS as much as being an alongside part of it. At least, that's the way it was viewed in that world. And because of that, I liked it.

    My education turned out to be less and less useless as I got on with my career in networking. I managed to get a graduation position and finished my degree - probably the wisest and most relieving move I made during my career. Not even obtaining my CCIE (hopefully, soon, if the fsck'ing proctor will be reasonable this time) will be as good as that was. And although the education hasn't got much to do with my current job (network consultant/engineer), I keep on finding out that in fact those years were not totally useless.

    I have no use for the skill of knowing how a C-compiler works. The practice I had in tracking a bug in a pile of code, though, helps me in finding errors in a network now. I never make a calculation using the Calculus and other kinds of maths I had any more. I do, however, make use of the ways they forced me to think while teaching me those subjects.

    So, in short: The education will be good for loads of other stuff then just hacking code. Nowadays, I'm doing the l33t3st stuff (in my opinion, anyways) with my job and loving it (and, yes, making the big-ass salary). It's all I hoped to do, in spite and because of the fact that it is NOT computer-science. And if you want to invent a new wheel: Write an RFC! You'll just need the experience first :-)
