    This is a massive part of it. It's easy, even trivial, to develop a system more secure than this. You can just use HTTPS and any API. Even if you completely forget certificate pinning etc. it is still more secure than this.

  8. Re:Need sailors to vette sea stories on Computer-Controlled Cargo Sailing Vessels Go Slow, Frugal · · Score: 1

    I used to work on container ships. Every vessel I was on could achieve at least 25kts, and some 26kts during sea trials. The engine was being loaded more than the design limits though, so the maximum we could achieve day to day was 24-24.5kts. We frequently did do this and could sustain it for a Pacific or Atlantic crossing. There were no real reliability problems, but fuel and cylinder oil lubrication went up massively. The planners clearly thought it was worth it though. Warships can do much higher speeds - like you say, 30+kts isn't uncommon. However, the warships I have looked at have their already quite poor range halved by changing from 20kts to 30kts. We could circumnavigate the globe at full speed without refuelling. Also because of the gas turbines warships use, they need to run on marine diesel oil, rather than the heavy fuel oil that slow speed diesel engines run on. MDO is about 4 times as expensive as HFO. So warships cost more to run. So, we frequently found ourselves making journeys faster than warships. I'm not saying they couldn't have caught up if they wanted to, but they didn't.

    Jump starting cars improperly can sometimes trigger the central locking - when you are outside the car, with the keys in the ignition.

  18. FPGAs on Recommend Reading for FPGAs and VHDL? · · Score: 2, Interesting

    FPGAs are my thing really, I think they are one of the best ways into electronic design if it isn't your career.

    I'm not up on Xilinx at all, but I've used most of the Altera FPGAs available. They are all pretty amazing devices, and all have their own dedicated features such as memory, DSP, fast IO, things like that. Learn about the structure of the FPGA from the data sheets to see how they work, and recommended applications.

    If you are doing anything reasonably complex, rely on the automated routing and placing. It's simply too complex for a human to do well. When you want that bit extra speed, or maybe when you are nearing 100% usage, then start manually tweaking the automated system - there are some really clever tricks to be done here.

    I did some fairly basic projects to start with (a digital function generator, an IIR filter, a display processor) which were guided coursework assignments. They gave me the grounding in the tools and techniques required.

    I think VHDL is my favourite language. It's so different to conventional programming, and again you can learn some really neat tricks to do jobs. A neat project was a biquad filter which used a systolic array of very similar blocks - watching how it ran as a simulation was interesting.

    I think the best thing though is to come up with a complex and real world application, and build up from there. Buy some of the reference books, but do something that will really tax you - it's far more interesting doing something like this all by yourself than using books to do projects of things already designed 30 years ago.

    Computer architecture is an exciting and unexplored field. Read some papers on new ideas, like asynchronous processors, or multicore processors, and try and implement some of the ideas. It's a good way to bring the world of hardware programming and software programming together.

    I ended up developing a multiprocessor system on a chip. Which as an individual I think is a great achievement. I learnt so much doing it.

    I should have added that we always upgrade to SP2, the advantages far outweigh the disadvantages, especially on business machines.

    The registry hacks that involve restricting activex, adding restricted sites etc. that we do are almost the same as the ones used by Spyware Blaster - expect we use more sources of information, and do several things this doesn't. Also works out a lot smaller, and doesn't need to be installed.

    Do you find that the SP2 firewall is inadequate? After watching many users just click "Allow" in most third party firewall applications, I tried SP2 firewall, and found it to be more effective under the control of someone who does not know what they are doing. Though, in most situations, the machines are behind an existing hardware firewall.

    I should ad (hoho) that one major advantage of Spybot S&D is that you can schedule it to run quietly in the background... this just isn't possible with any of the other free tools. The command that does it:

    spybotsd /autoupdate /autocheck /autofix /autoclose /autoimmunize /taskbarhide

    There are other tools that help massively with spyware. As a consultant, it's equally important to understand the ways and means spyware gets onto the system, so that you can prevent and cure effectively, and respond to new spyware before the automated tools do it or before it appears on the many forums.

    • Sysinternals Utils are free and great. Process Explorer replaces the crippled useless tasklist in XP, and is quicker and easier to use than the command line utils. Filemon, Regmon, and Diskmon allow you to monitor files, registry keys, and disk access - you can see how, when, and why spyware is getting in.
    • WhoLockMe - appears on the right click menu in explorer, and shows what is causing a file to be locked. Again, this can be done at the command line, but this makes life that little bit easier.
    • Knoppix - for when it all goes very very wrong.... recover files, partition tables, reset passwords, even edit the registry
  25. Spyware tips I've picked up on Failing Grades For Most Anti-Spyware Tools · · Score: 4, Informative

    I run a small IT consultancy, and nearly every internet connected PC we work on has a significant spyware infection on it. It's not only our job to remove it, but to prevent it coming back. The things that I've noticed after fixing a lot of problems:

    • People don't know they have spyware on their computers. They are crawling along, at a stage I would call barely usable, and it doesn't bother them in the slightest. Or, better still, they find those new toolbars really useful...
    • A combination of Spybot S&D and Adaware will clean up most problems. Hijackthis will then allow you to remove anything else. Some people say that Hijackthis is the only tool you need - but it can only remove very apparent problems, whereas the other tools will remove nearly all associated keys, files etc.
    • To prevent re-infection, you need to lock down the machine whilst it remains usable. People really do not want to change, or put any effort in. You can try putting Firefox and Thunderbird on the PC, but most people will choose IE, or complain if you hide IE, so they don't have the option.
    • Change the settings for the zones in IE to be more secure.
    • Add a big list of bad sites to the restricted zone in IE. This includes some sites that have content, but it's generally porn, and as our users are business users, they won't call us back to give them access to a porn site.
    • Add an even bigger list of ActiveX CLSIDs to not run.
    • Stop the default action on windows scripting host files, scr files etc. from "run" to "edit". A lot of problems start with some user interaction, and this has cut down on quite a few (mainly non spyware) problems.
    • A lot more small registry tweaks can be done... most of the above is done automatically by scripts we have writen. One of the problems we found was adding keys once to each HKCU hive - you don't want to overwrite them at each login, or the user changes will be forgotten, but none of the Run, RunOnce etc. keys do it per user.
    • Add some buttons to the IE toolbar to put sites in the trusted or restricted zones, for when people have problems.
    • Install Spyware Guard - this provides some active protection against spyware.

    This won't stop everything by any means, but it slows down reinfection. End users need to change habits - reading EULA, not just clicking OK, using passwords - but this isn't something you can do with a couple of hours work, so people aren't willing to do it. I have no solution to that problem.
