    The CPU still starts up in 8088 8 bit mode. The problem is that MS largely doesn't care about its legacy API. They don't reimplement them or improve them (when was the last time they improved or even touched the COM interfaces or old Win16 macros?), they just build more on top and when it breaks they say: just use the old version.

  3. Software licensing and legacy on Why Does Microsoft Still Offer a 32-bit OS? (backblaze.com) · · Score: 1

    Some software doesn't run on 64 bit, a bit of a problem with the Windows legacy is that all forms of API, both public and private have to be continue to be supported, just like Itanium and SPARC, PPC or Alpha for certain Linux and Unix distro.

    Another issue is licensing, especially Database and data processing from big companies like IBM, Oracle but a lot of niche closed source software has the same problem, 64 bit versions simply cost more because back in the day, that's how you got access to more than 4GB of RAM.

    Then there is Office. Doesn't work well on 64 bit machines. Works fine on 32 bit.

    You can take any irrational number and find any value in it. The problem is that you can't truly compress anything that way, your coefficients will be the same size or larger than any number you're trying to get as a result (the optimum compression can never be better than 2:1). If you're looking for "lossy" compression (basically, some values (but no more than x %) can change, you'd still have to look through the nearly infinite space for possible values and at best you'll get some compression close to whatever entropy allows.

    To encode all data that's currently being stored or generated this way by humankind, your encoder would have to work through ~2000 exabytes.

    Yes, but by the time you have encoded every possible combination that can be represented in a 'movie' (everything that's ever passed any screen), you need an infinite size 'database' and as your database grows, so will your pointers so your pointers will eventually become larger than the thing you're trying to encode.

    His encoding scheme was basically: Let's send everyone all movies ever made (which with good inter-frame compressions would be as close to mathematically optimal) and use a DRM key to unlock which one they can watch.

    It's not "impossible", you could equally make a pointer to any place in an irrational number (eg. find the nth digit of Pi) but the pointer is going to have the same size as the result.

    Eg. you can find sla in Pi at position 91104776 and thus you could work back and forth the text. But encoding 3 bytes took ~3.5 bytes. Even if you were to compress that pointer (which can only be up to 2:1), your encoding is no better than what compression already exists.

    If you read the original stories in Dutch, the whole story becomes a lot clearer.

    The system he had was enclosed in a box and you could initially see his "demo" of 4 movies in low quality. There were various claims on Sloot's part that it was only x size but nobody was allowed to look into or program the system. He was going around investors fishing for money to make it work at bigger resolutions for his lossless compression algorithm. When he croaked nobody found anything in regards source code or design documents.

    It's also mathematically impossible to get the file compressions he got. At best it was a reference to a pre-programmed movie.

    Every energy plant already has load banks, you can't just turn off coal or nuclear plants so they need it anyway. Wind turbines have brakes and can be fully locked out.

    These prices are just cost on the futures market. It is indeed government subsidy that is being 'paid back' to speculators.

  11. Re:subsidy on It's Been So Windy in Europe That Electricity Prices Have Turned Negative (vice.com) · · Score: 3, Insightful

    Doesn't quite work that way. There is no such thing as an oversupply on an electric grid. Just because you have a wall wart that can supply 2000mA doesn't mean it will blow up your cell phone that only needs 500mA.

    These are point prices on the energy market and works much like stock and futures markets. It's not like they go knocking at people's door to beg them to use energy, the end user still pays an exorbitant amount ($1+) per kWh at the end of the month. This is just a temporary swing in the futures of "supply cost" which is a very small chunk of the final cost, usage taxes, green buildout taxes, regulatory cost, network maintenance and energy transport costs make up the majority of the bill.

    The reason for this is indeed subsidies, which you pay for in taxes. So the state subsidizes "green" power, but you can't just turn off your nuclear and other plants, that would be both dangerous and take days to recover. So you keep supplying power and as always, the only option is to turn off flexible generators (solar and wind), the problem is that you now have a bunch of money the government gives you per kWh the green energy plant "generates" but there is no demand and you can't legally keep/collect the money, so now the people that have paid for the futures of the green energy plant get paid back based on how much the plant would've generated if it were running.

    So the end users are paying speculators through taxes levied on their energy bills for the energy that doesn't end up being generated.

    It just goes to show that this isn't real "AI" and that we have no effective "AI" as of yet. A "true" AI would "learn" patterns without having to hold onto all the details.

  13. Then send 1 bit per second. Across the entire router, this could still be easily 10-20bits/s and even 1 bit/s is plenty to extract information like encryption keys. As long as I can modulate the behavior of the LED's, I can send data. The reason I can modulate the LED's in the first place is so the system doesn't need the extra circuitry to detect packets moving on the network, just wire it directly to the CPU and let it handle the blinking.

    You can avoid these attacks by directly attaching the LED via a circuit to the data line and make it blink based on packets moving across the network, but that costs a few extra resistors, capacitors and perhaps even a chip (or not having LED's at all but there is a reason for them)

    Yes the type attributes of some elements is deprecated. For the input tag, they still exist, but DateTime and DateTime-Local in particular has been both on and off the chopping block as has "color" and a number of other ones and the worst thing is, all the other ones (telephone, number) have been modified (number in particular, now you should no longer specify a maximum number) and do not specify a unified format so depending on browser you could get a number of different values returned.

    You can even go from one version to another version of Chrome and get an entirely different value returned for some of those types based on the current flavor of what should be in the 'standard'.

    The best thing to do with input fields is, if you want them formatted, to do it in JavaScript because the W3C has absolutely no clue on what they're doing. Furthermore we now have WHATWG and W3C both saying different things about the HTML5 specification.

    I love Safari and its developer tools are way easier to use and more polished than either Chrome or Firefox and pages with heavy JavaScript render visibly faster . The only problem is some libraries like jQuery aren't the most compatible resulting in some weird behavior. Safari will also halt bad JS earlier while Chrome sometimes tries to trudge through things with disastrous results.

    I've never had problems with WebRTC support in Safari although that's probably because I only use open source software, no crapware like Google Hangouts, Facebook and Slack (and I've used WebRTC since Adobe Flash was the only implementation).

    Making a living wage is not a problem for most of these people but they still don't want to shell out for a $3k laptop or a $2k TV and who would, if you can get one for free with minimal to no chance of ever getting caught and if you do get caught, minimal to no punishment.

    A luggage handler may get fired but no investigation will be started because it makes the company look bad and may uncover more than they are willing to share. So with the people here that get caught misappropriating funds, the image of the organization and the need to accept more and more public money is far more important than any official investigation or report on the practice.

    It's a distributed data storage/processing system. Whether it's useful depends on your project.

    A good programmer makes sure that their storage and database backend is replaceable and good backend projects make sure that they support at least somewhat standard methods and functions.

    The problem with most of these implementations is they're relatively expensive for small setups. You need 3 dedicated nodes at least to make it "work" well enough and it still has huge amounts of overhead compared to a classic system. They really become useful when you can afford and/or need hundreds of nodes spanning multiple data centers.
