Testing is why companies maintain that old code. Will you guarantee you'll hit every little program patch put into 20+ year old code. At my company we have been modernizing stuff, but we hit the "hidden" logic from 10 years ago quite often. Somebody might have put one line of code to treat our favorite customer's orders differently in the middle of some massive program. You don't find out until somebody calls a month later because they aren't getting their standard discount which always just "was".
Ripping out old code and replacing is not for the feint of heart, you can put your company in a bunch of hurt missing a hidden calculation that's not documented. The only solution is massive testing, which means pulling actual employees off their regular jobs to perform a week's worth of work to check every single digit of every page of every report they touch in a day.
because these programs were written when programs only got 32KB to run, they had to make every bit count. That old logic is still in the programs and you have to understand how tightly things were pinched before you go fattening things up.
Also, those 8 minutes grow greatly when you have 10 plants sharing the same system.... that's 80 minutes of the day when running month end tasks, and they all have to complete the same day.
the application has to do with harmonics. For example the classic problem is that bridge that collapsed under wind load in the 40's. It collapsed partly because harmonics from the wind, just like a whistle, built up. Part of breaking harmonics is having a quick list of numbers that you can be sure won't duplicate. In a bridge you might pick your structural members to be just a little "off" using proportions from this list so that no two pieces were identical, one way of reducing vibrations in the structure.
Each length appears exactly once on the list and they can never be repeated unless you pick the exact same line segment.
it's essentially defines a list of numbers such that if you pick any two segments that are not the same segment they will always have different lengths. This is useful for things that involve harmonics.. radio, buildings, ect. where you need to build "imperfect" shapes. With antennas this is so that they don't interfere with each other in close proximity. With bridges you might need to make each length of bridge section a slightly different length to keep the bridge from vibrating to pieces. It's a list, highly useful to engineers of various types. Not that exciting, unless you really needed to have 25 critical measurements when 24 just wouldn't do.
bingo! Greenspan did exactly what all the Republicans and Libertarians wanted... lowered the interest rate the Fed charged for money and kept their fingers out of market regulation. Wall Street spent and gambled like drunken sailors.. they deserve to have been shut down, their employees laid off without paychecks like all the manufacturing workers they sold out, but they're so big and tie up so much money it will put the honest people out of business too.
Enterprise drives tend to stick to the 146GB limit and go for speed and smaller size. Simply because using cheaper 1TB disks sounds nice but that's too much data to recover in one failure. What's the chances of another drive having a different problem or a corrupt file when you try to rebuild by the TB... you have to account for that Murphy guy. Like you said also, the extra spindles help for moving the data around during recovery as well.
the topic is not flawed. It does happen that in a highly error ridden raid setup near the end of the drives lives that when one drive goes another (from the same batch in the same operating conditions!) will die from the excess wear and tear trying to recover the data. I think this happened to one of our servers at work and they had to restore the whole thing from tape on a backup server.
Something like Time Machine is a second copy of one computer. If the computer dies the chances of the drive dying at the same time are slim and visa versa. With something like Drobo, now you can have several machines in one location and if one of the array fails it can be replaced without losing data. Good enough for most people as long as the data is synced well.
iTunes... once you start with TV shows disk fills up very fast and you have to back your own stuff up Apple frowns upon letting you download all of it over again.
If she has received threats then a crime has definitely been committed. Perhaps the way to deal with it is not as a spoofed phone, but why are people she doesn't know making threats. Those people should be easy to track... let them explain to the telco and feds why they said that thing to a little old lady.
look at the Apple iPhone SDK... even without "owning" your work they can summarily shut down your project from ever shipping if they don't like one little thing. Microsoft has similar "non-competition" requirements in their development tools (you can't write and office suite with certain Visual Studio tools and you can't write certain modules Microsoft wants to charge for) as well for USING their libraries included with Windows, not even for copying them. OSS is far more reasonable than commercial software it's just that windows programmers have played fast and loose with copyright for years because Microsoft encouraged everything to be "theirs" and passed around without any auditing.
they're not... you don't BUY windows from Microsoft.. it is distributed by OEMS so it's Asus's fault if their PCS ship with malware on the Windows disc. (wait that happened just last week! and ASUS is the starter OEM for many commercial PC operations)
can you trust Adobe Flash, Apple Quicktime or Microsoft Windows? Those all have regular security breaches where literally anybody can find a bug and exploit it from a website.
Has any of your Staff actually READ the EULAs? Those companies regularly add stuff to actually spy on users or disable software remotely. They assume ZERO dollars of liability for routine bugs that lose your important data and Zero liability when their software gets hacked and causes data breeches. Microsoft changes the terms of the Windows License with nearly every patch and you can't do a damn thing about it. GPL has changed how many times between V2 and V3?
that's why a previous poster mentioned using a simply shotgun action. Those are legal everywhere with no special rules...as it's a "disabled" weapon. gotta love the NRA.
what happens when disgruntled air travelers start threatening the staff that's stealing stuff? Shouldn't we prevent that NOW by not allowing them to steal stuff?
except when people choose not to fly the feds pumped money into the airlines so they wouldn't fail... and other companies wouldn't build out buses or trains.
it's perfect "plausible denyability" for the thieves. By law they MUST open luggage to search it... they just add that little "we opened this" ticket and it's all good.. or they open and extra, swipe stuff and don't report it. Either way they have to open packages and the boss probably goes to meetings leaving them alone to do what they want.
that's not quite right. The TSA has the right to search anything in the airport. They allow minimum wage trailer trash to perform this without any oversight. Again, if these low-level grunts are capable of sneaking that much stolen stuff OUT of the airport without meeting security blocks, what the hell can they bring INTO the airport without inspection? This person is a huge violation of trust and the airport and TSA management is equally to blame that this got so far.
OK, say the ISP pre-approves the media before you can upload it. What then happens when the inevitable DMCA nuisance notices start to come in? Is that enough for the ISP to NOT take down your stuff because you have affirmed it's your material? If it's not enough to stop a DMCA letter than requiring the authorizations before posting is just wasted time and energy.

media life is the same whether the media dies or you can't get a working drive for a reasonable amount of time or money.

that makes a camera a WMD... F*ing liberal media terrorists.

and if you did float on water, you'd be different than the rest of us so we'd burn you for being a witch/terrorist.
whoa there partner!!!!
Our security folk are irreproachable heroes.. why should we put more stress on them doing such patriotic work?
except when people choose not to fly the feds pumped money into the airlines so they wouldn't fail... and other companies wouldn't build out buses or trains.
those were all Americans though... funny that all the extra stress causes the people IN the US to act out.
