Gee - and the average policemans gun is fired in anger how many times during it's life? Prior to the current war in Iraq you could pretty much say the same thing for the average Military rifle, or artillery piece, or tank, or machine gun...
Have it, and hope you don't need it is a LOT better than Need it - and don't have it
Oh - and BTW - there IS another way - and we can trace through the idea - lets see where it leads (give me time - you'll see how this is NOT OT by the end):
As you may know if you've ever delt with analog racks and patch bays, back when, someone came up with the idea of an electronic patch bay. Instead of moving a physical patch from jack 1 to jack 7, you tell the patch bay to connect jack 1 to jack 7 with a command..
The NEXT step in the process is we take the signal, and we come up with a way to do 2 things - tell the patch bay we WANT a connection and when we are done with it - and we have a way to tell the patch bay where we want to connect. Let's say we do the first part by having a 48 DC volt idle voltage drop to about 6 volts when we want a connection, and when we are done, we raise the voltage back to 48 volts. We then signal who we want to connect to with a series of 10 sets of pulses of the control voltage - each pulse set moving a relay stack
We've just invented the rotary dial telephone
Now, electronics comes along, and we replace the pulses with tones - we have touch tone. But we still have this problem. Your local rack has a LOT of wires going to other racks - wires, particularly wires between cities, cost BIG money. So using this new fangled electronics, we first devise an analog way to put more than one signal on a wire, and break them up on the other side, by shifting frequencies - we'll call this "Multiplexing". We eventually come up with the idea of digitizing this data, and we do that -
But now we realize - there is a LOT of dead space in each data stream - so we can break the steam up into little chunks -lets call them packets, and tag a sender, and a destination on to each packet, and stuff them on the wire. We decide which wire to send them to on a packet by packet basis, based on the header information - and we let the machine on the other side decide where to send them... (starting to sound familiar?)
OK - to make a LONG story short - we've invented these rally nice, highly flexible electronic patch bays - they are called routers/switches
You stuff one in EVERY rack - all gear goes to the router - the router decides if the packet is local - and you send it by the one FAT pipe out of the rack to the central patch bay (a bay full of routers) for it to be moved betwen racks...
Of course this assumes you can deal with packet latency, and have a fat enough pipe to handle the inter rack traffic (otherwise, run more than one pipe)
In theory (yeah I know the difference between theory and practice) - in todays day and age, there should be ONE wire coming out of each rack - that's it! The wire coming out of the router - that goes to the router bay - and you think of a lan room like a big rack...
Want to patch device 1, in rack 6, lan room 12, company 220 to device 3, rack 22, lanrom 14, company 156? Maybe you just tell the router that 220.12.6.1 goes to 156.14.22.3?
Look at the history of those big dumb telcos - they are not so dumb, and can still support legacy gear from WAY back when
BTW I forgot to point out - you are making a MAJOR mistake if you think you need a full mesh - and that you run wires from 5 to 15 and also 5 to 22!!
Lets say your main patch bay is rack #1 (note - not patch PANEL - patch BAY - a full rack of patches)
When you want a cable that goes from 5 to 22 - the wire goes like so: Equipment in rack5 > Patch Panel in Rack 5 Patch Panel in Rack 5 > Patch Bay in RACK 1 Patch Bay in Rack 1 to Patch Panel in Rack 22 Patch Panel in Rack 22 to Equipment in Rack 22
Replace the #22 with #15 for rack 15
Now - you now need to go to a backup gear in rack 16, to replace something in rack 22
You go to the pach BAY - pull patch that connects #5>#22, and move it to connect to #16 - your DONE (assuming you have the patch panel in rack 16 configured)
BTW in Audio-video, patch panels are often "normaling" - if the normal, original design has rack 5, cable 1 attached to Rack 22, cable 6, they will be one above the other in the patch bay - and best yet - if there is NO cable in the patch holes, they are automatically connected to each other by the panel itself. Under NORMAL operations, you walk by the patch bay and patch panels and se NO patches
I didn't say you were not going to spend MONEY and TIME and space - but once it's RIGHT....
I wish I could show the photos of some of the wiring downstairs - hint - the raised floor is a FLOOR - aka there is a full sub-basement under the wiring racks - and the master patch bay is something like 20 RACKS wide - NOTHING but patches in each rack
One of my friends here at work designs Network TV studio wiring. I would LOVE to post a photo to "Master Control" over here, but even taking a photo is off limits
Folks should get a gander inside one of the "Remote Trucks" at a Football game or a NASCAR race - here is gear that has to be packed up, MOVED, setup DIFFERENTLY, in a different location, and repeat, all season. The design of the wiring there, and how it's done could teach most IS shops a lesson. Then again, they are paying folks GOOD money to design this stuff, and TV stations realize that the signal is their product, and will SPEND - of course, we also have some horrid IT wiring, because it's NOT the product, and they cut corners
I'm going to be redundant here - as I've said it in 2-3 other messages. You use patch panels for flexibility. Yeah, they cost money. The FLEX comes in designing you panel correctly - NO wire goes direct from unit "A" to Unit "B" - it goes - Unit A to Patch Panel in rack where A is - to fixed wiring - to Patch Panel in rack where unit B is, to Unit B - even if they are in the same rack
That's why they invented PATCH PANELS - the wiring coming into/out of the rack is bundled, and goes to the patch panel - NEVER to an item in the rack - in fact, even wiring intra rack goes via a panel
Yep, Telcos, Radio Stations, TV Stations etc have been lacing cables for a LONG LONG time (12 cord anyone )
The back of the rack should be designed that it doesn't change - spare cables etc - patch bays in the front that are well thought out
BTW folks - FILL your patch bay!! If they give you 32 patches, don't run 20 cables to it - put in the 12 spares - you'll use them sooner or later. That's why when you see a telco cable, you'll see multiples of 25 pairs - 25 pairs = 1 block
The TRICK in that kind of wiring is patch bays, and EXTRA runs/spares to every OTHER bay. You repatch on the bay etc. More work up front, less down the road
Go look at a TV station, or a Radio Station. They've only been doing it decades longer than we have
Which is your option with the subway - the searchpoint is outside the turnsyles - they just say "if you want to enter, you must consent to seach, or you may leave" - BTW - go to the next entrance down the block - it will NEVER have a search team... Dumb, yes, legal yes, will only catch stupid folks, yes, wrong? HELL yes
Well, besides my medice, I fly with needed medical devices - I lose it - and I go to sleep that night, I might not wake up in the AM - you think I want to CHECK that? RIGHT....
as I said - he said they DO tell them about the right to attourney, and in fact, have one at central booking to meet you there (Queens is a BIG place, and there are always lawyers there) - you come in, and an a Public Defender is right there - you are given your rights in front of him - aka the cops don't BOTHER until your back at the precinct or at central booking
If I said they don't read them to you at all - I stated it wrong - it's just NOT at the moment your arrested - it's when you get to the police station or central booking - and they are NOT going to worry about any statements you made in the car on the way there, as it would be almost impossible to use against you.
Actually, the cop NEVER has to read you your Miranda rights - even when you are under arrest. They ONLY have to read you your Miranda warnings IF they want to use your statements against you.
I know here in Queens County, I asked the DA about this (I was on Grand Jury) - he said that they often don't bother - bring the guy in, offer the one call, and a lawyer, and never bother with the "statements can and will" - because they have so much evidence, that the persons statements make NO difference in the case. In fact, he said that the claims of coerced confessions are used in court by the defense so often, that confessions/statements are almost worthless UNLESS videotaped, with full warnings, discussions of the rights etc before hand, on tape, that they don't bother
I WAS refereing to GUN crime - sorry if I was not specific (my bad) - gun crime tends to go UP where it's harder to get legal firearms, and has trended down where it has been made easier to get firearms
One of the HUGE jokes in the RKBA circle was "How many crimes were committed with a licensed handgun in NYC in the last 40 YEARS?" - until oh, 4-5 years ago, when some ID10T ruined our record, the answer was NONE. Yep, NONE, but every time there is a well publicised handgun crime in the city, they say "we have to make it harder to get guns", and the toughen the rules to get legal firearms. Hint - if NO crimes are being committed with legal firearms, why punish those folks by making it harder to do things the legal way - obviously they are NOT the problem (1 crime in 40 years is NOT a big problem)
Actually, if you look, we went from 2 states with "shall issue" laws, to 38 (aka we made it MUCH easier for LAW ABIDING citizens to get guns), and guess what? Crime FELL in ALL those states....
Highest crime rates are where it's hardest to get legal firearms...
How about the SAME money? BUT the big thing it shows is it's NOT MONEY to the classroom that makes the difference (BTW another interesting factoid - a greater amount of money makes to to the classroom in the better districts, even though the get less money.. Wonder of the bureaucrats have anything to do with THAT
- Oh, and 20K/year? hahahahahahahahahahaha Maybe starting. But after spifs, the average teacher around here is in the 70s, and in Nassau, up in the 80s to 90s
Of course there is also the case that 1)The suck, but 2)Are NOT underfunded, but that they waste funds
Want a good joke? I'll look at NYC. Did you know that the best school districts (and there are some that are VERY good) actually get significantly LESS money per pupil than the horrible districts?
Did you know that the big 3 specialized High Schools (BxSci, Stuy, and Tech) get WAY less money than average?
Perhaps it IS time to suck the money out of the underperforming schools, and get the same results by paying the "teachers" minimum wage to watch the kids. Heck, the kids aren't learning anything anyway - and if we give their parents a voucher, maybe they will spend it on a school that WORKS.
IF (the big if) they can get the POS software the want/need
Like I said - they will probably evaluate whatever is available from the terms of the functionality of the POS software, choose 2-3 candidates, get quotes, and go from there
If there isn't a POS program that fits their bill in OSS, guess what? Aka for most companies, the functionality comes FIRST
They will upgrade based upon the POS software, NOT the OS that is under the software.
Most folks here on/. were not around for the Windows 3.x - win 95 VS OS/2 wars. Whant to know why Windows won? Marketing helped, but the BIG thing was Microsoft introduced this nifty, simple (and much maligned) programming tool that made it EASY for companies to get their custom apps on the desktop - Yep, Visual Basic, plus things like Visual C++ (and Borlands C++ and Pascal etc)
Companies don't _REALLY_ care what the OS is - they want to know what the computer can do for them, and if the best custom POS sale application runs on Windows, they'll buy Windows - if it runs on Linux, they'll buy boxes with Linux
It's not those wide market apps like Office and the like that make or break the OS (LACK of them will break the deal, but..), the BIG deal is ease of custom stuff - which is why "thin client", browser based applications were/are such a big deal. The BIG thing is that most custom applications just don't give the end users what they want VS "rich client"
Just remember that the Union has a significant interest in opposing ALL charter schools. From what I can see, most teachers unions have never met a Charter School that they liked....
Wonder why? Is it the kids, or is it the jobs/pay of the teachers...
No supposidly - I have heard (once) a tape like that, and it was more like "I've tried A, NG, I've tried B, NG, I've tried...(radio cutoff)"
I used to know someone who worked for the NTSB (obviously NOT test piolts) - he says you know what the most common last words of the pilot is in a plane crash? "Oh shit"
Hey, I admire you, and I'm a WAY out of shape guy. I've known 3-4 world class athletes (got to hold and Olympic silver one day. VERY cool) People don't realize what kind of work goes into it
The BEST description of it was I saw and interview with (can't remember who) and he said "You know what really bothers me? People who say 'I always wanted to XXX'. If you always wanted to XXX, you would have. You wanted to XXX when it was convienvient. I ALWAYS want to XXX, so I'm practicing, and training ALL the time, and have arranged my life around that."
One of those world class guys I knew was/is a shooter. A lot of people think it's the rifle, or the Ammo, or xxx. Yeah, they help. I've shot his rifle. I've shot with rifles that are darned close to his (and own one) - folks, he'll take your rifle, hand you his, and unless you are in that top 5% class, he'll still outshoot you. Once you get beyond a certain fairly reasonable level of gear in just about any sport, you're talking fairly small levels of improvement between the "best" gear, and the gear just slightly down. BTW in some sports, it's actually HARDER to use the top gear well. That gear, to get that extra 1% takes 25% more skill, and if you use it WRONG, you lose way more than 1%. The stuff that is 1 level down is a LOT more forgiving of mistakes
