one thing you see sometimes (often for goods use)are elevators with manually operated concertina style doors. I think theese make it much easier to get a wide opening for the entry than the sliding doors seen on passenger lifts. The trouble with them is if you don't shut both doors very carefully the lift will end up stuck at whatever level you left it at .
on the one hand they do contribute a lot of code to the opensource movement and they should be applauded for doing so!
on the other hand they released rh9 which was known to be a pita to get a lot of software to work on. then they scrapped rhl altogther and moved to fedora with its insanely fast release schedule and which afaict wasn't properly stabalised before rh9 was eoled.
i really got the impression that they wanted to force people to switch to rhel.
sure there is the rhel rebuilds but you really get the feeling that redhat would rather those didn't exist.
Yes, product keys are a PITA. However, as a developer and software publisher, I understand their need. People want everything for free, and they don't want to pay.
how exactly do product keys help you make people pay?
well a stop the world garbage collector is extremely bad for percieved performance even if its aggregate cpu time usage is smaller than that of reference counting. I think that may be one of the things that got early java a bad name.
I DON'T CARE if code is slightly and CONSISTANTLY slower than the best achiveable, that can be optimised if it becomes a problem. I DO CARE about unpredicatable long hangs.
btw whats the GC like in opensource java atm? from things i've read i get the impression its nowhere near as advanced as what sun is using nowadays.
WTF is the point of product keys for normal retail software (assuming no centralised online service like with some games and no activation systems of a kind that only a big company could get away with)? sure if a particular key gets particularlly widespread you can ban it from upgrades but your going to be playing a seriously hard game of whack a mole that way.
all product keys ms style do is piss off legitimate users who can't find the box or manual with the key printed on it
You forgot 4) Microsoft wants to cement the fiction that you actually need a licence to run software you have already purchased.
whilst copying your retail software onto your own machine to use it yourself may well not require a license i'm pretty damn sure copying it onto every machine in your company from one source (and who wan'ts to deal with a seperate retail copy for every user?) does.
the quality of stereo vision depends on the ratio of the distances between the two views and the distance to the object.
human eyes are good enough at it for everyday uses but not for judging depth in anything more than a few meters away. For longer distance ranging we rely on our knowlage of the size of objects.
my experiance is if you don't snipe then you will just get outbid repeatedly until the current bid is moret ahn you are willing to pay whereas if you wait paitently and snipe you have a much better chance of actually snagging a bargin.
imo the reason sniping works is because many of your competitors place a bid and hope they win but will pay more than thier initial bid when they get the outbid e-mail. sniping means by the time they get that e-mail its too late for them to compete with you.
ofc if everyone snipes it becomes essentially like a sealed bid auction where you get one chance to bid and win.
1. Is it possible for more than one WiFi router to cover a given hotspot? This has nothing to do with routers. Whilst some domestic kit has a nat router in the same box as the access point you won't see this in any serious installation it would be an administrative nightmate. Assuming you meant more than one access poitn in a given area your main limitation is that you only have 3 non-overlapping channels. You can have multiple access points on the same or overlapping channels but that can cause performance to such big time.
2. If so, how would the client choose which router to use? every access point has a configurable SSID that the user can enter in thier client to select a network to connect to although some clients are known to chanage to a network with another SSID if they lose access to the one they are supposed to be connected to
3. How many routers could occupy a hotspot before service is seriously harmed? see answer to first question.
rofl you americans can't even get universal mobile phone coverage accross your massive country and you really belive that a short range system like wi-fi will ever approach universal coverage?!
from a quick test that rom seems like a rather poor tetris clone. it freezes the peice far to quickly making it basically impossible to push it under another one.
a system that only played nes carts would be of somewhat limited marketability.
Oh really? What makes you think that?
1: it would have to be quite bulky and/or not enclose the cart (nes carts aren't exactly small)
2: if you started seriously marketing them in any one area you'd cause a run on stocks of old nes carts locally. Maybe this wouldn't be a problem if you only sold them online though.
nes knockoffs bundled with a huge rom full of nes games will be as illegal as ever.
Not if the "huge rom full of nes games" is actually "The Best of PDROMS.de". There's a project going on over at nesdev.com called "Garage Cart" to do just that, and I'm contributing a tetramino game. true but just how good are those PD roms?
even if they can make a legal nes clone they can't legally include its back catalogue of games and a system that only played nes carts would be of somewhat limited marketability.

if you do your voltage conversion with a transformer smpsu (which afaict is what PCs do) then you get just the same isolation whether the input is AC or DC.
oh and the DC ground of most pcs is connected to mains ground anyway so they aren't isolated.
we already do have a linear time measurement its called TAI iirc
local earth time is what we humans naturally work on, we get up at sometime arround dawn and go to bed at sometime arround dusk.
the problem is essentially using earth time directly for day-day use is impractical as its difficult to measure accuracy. but using linear atom time would mean that we get more and more out of sync with the sun.
the resulting comprimise is to base our civil time on UTC which is linear atom time with leap second adjustments to keep it close to earth time. The trouble is that leap seconds are an annoying complication that are frequently handled incorrectly and so some are pushing to eliminate them and put up with the drift it would place between civil time and earth time and/or correct for it in much larger chunks.
there are a couple of reasons i can think of why java wasn't a roaring succes.
1: thanks to the sun vs ms issue developing browser applets that will run without 3rd party software required working in a horriblly old version of java and you couldn't even use the swing classes without downloading them at applet load time.
2: also a lot of java applets wouldn't work if you were browsing from behind a http proxy as they used other protocols to talk back.
3: you can't exactly call awt or swing nice to program for;)
while i admit i'm slightly newer here than you (at least as a registered user i was posting as an AC long before i got an account here) i'd like to know what it was in your post that make you give the "you must be new here" response.

Well, no, but it does require the class to expose a method that does the right thing. That isn't much different from the class implementing the right interface.
its not if its your code thats constructing the instances but its not always. Quite a few java libraries return arrays of objects and if you wan't to fill a combo box with that information you are going to have to convert it to strings. The tostring method might do what you wan't but it might not.
the problem here is the patent holder holds all the cards. If there is no reasonable alternative you have to pay whatever he wants and that may well be a large enough sum to kill your product.
and thats assuming they don't just totally refuse to license it to you. An arsehole with a goverment granted monopoly can be a dangerous thing.

it doesn't seem very MS like to give up possible licensing revenue.
i see several possibilities
1: ms thought this would end up being allowed by uk law whether they liked it or not and decided to do a deal before it wen't to court.
2: they wanted to hurt existing resellers who were being disloyal
3: they wanted to provide a kickback to someone.

also note that the sheer number of ipv6 addresses will make it virtually impossible to hit using a random scan.
