A modern email system really should be able to handle this. High performance messaging systems will store one copy of the message, with n number of pointers to it per back end store. Sending a message to 10k users results in one store insert event and a 9,999 cheap pointer operations. The MTA will have to perform directory look ups for the recipients, but should use LMTP to insert them into the store and prevent redundant directory queries, etc... Sun's big mail server will even "relink" duplicate messages in the store that arise from user migrations, and free up disk space.
~300 - message per second insert rates with 50 kbyte average sizes is possible on modern workgroup class servers and disk arrays.
Bring back the "paperboy" and afternoon delivery

Are Newspapers Doomed?

I used to be a paperboy. It taught me important work ethics & skills, and kept me in shape. When I provided superior service, I made more money. When I screwed up, I lost customers, and I had to replace broken windows and screen doors. I bought my first computer, a Sinclair ZX-81 with money I made on my paper route. (That I returned it immediately, and bought a VIC-20 is besides the point...)
They did away with paperboys and afternoon delivery in the mid-80's. I still subscribe to a local paper. Some nameless faceless carrier delivers it to the soggy ditch in front of my house at 5 am in a car with a noisy muffler. It costs 5x more than it used to. I usually don't have time to read it in the morning. If I think something worthwhile may be inside, it might get carried to work with me. Most of the time it gets tossed up on the porch (where it should have been in the first place...) and left till I get home. At that point, it's stale news, and it often goes straight to the recycle pile.
When I do read it, it's all left leaning opinion masquerading as journalism. All preaching, no in-depth reporting that helps me understand and perform my civic duties. All the reporters come from the same schools of journalism, and think the same way. They're employed by the same large media companies that have the same self-interests, and push the same agendas.
There was some discussion weeks ago that Obama's biggest problem was the "old men" in Congress. The old line 60's liberals are running out of time, and they know it. When Clinton came into office after 12 years of Republican presidents, they essentially wrecked his presidency by causing the 94 backlash. Now they're in the twilight of their careers. This is their last chance.
Term limits have a down side. Just ask anyone that was living in California back around 2000. The state legislature was full of people with no experience, and no long term commitment. They're still paying for the "power crisis", as well as the financial ineptitude of a never ending string of inexperienced legislators.
I still think direct election of the senate was a mistake. The original appointment scheme made them beholden to their states.
Most upcoming highway-speed EVs use advanced li-ion.
Serious question... How many cars need replacing, how much lithium is needed in each, and how much economically recoverable lithium exists here on Earth?
The problem is, they need to keep themselves warm. Once the internal heaters are powered off, the batteries and electronics freeze up. It's cold enough on Mars that the differential expansion rates of the chip dies and the substrates they're mounted on will crack the chips. Once that happens, they're done.
take old worthless computer, install second nic ($10), install latest ipcop, setup - and enjoy. No needing to learn ios, plus you get free snort - registration required but free. Many addons available and comes with traffic graphing etc.:D But no ADs...
Nothing new/useful added to your resume, it burns 5x the power of an 851, and no WiFi...
Having said all that... it would work. I'm not knocking it. Just pointing out that a real router is not out of reach.
This being Slashdot, I'll point out that a Cisco 851w, which runs IOS 12.4 with an appropriate feature set for most ADSL users, can be had on Newegg for around $350.
Sun makes a mailserver that runs some of the largest ISP's. Something like 30% of all mailboxes on the planet, with individual deployments larger than 5 million mailboxes a common sight.
A 50,000 seat University should be able to fit on a single T5120 and FC/AL disk array hidden in a basement somewhere. The trick with email is to not skimp on the disk. Email is an I/O problem. Disk speed is everything. The 5120 has a direct I/O channel that is perfect for an FC/AL card and storage array.
Yes. He's mad than Sun dropped support for a 15+ year old processor architecture over 6 years ago. Never mind that there were truckloads of Ultra 1 & 2 machines for sale cheap on eBay at the time, any one of which could have filled the void left in his life by the death of sun4m.
Now if he's talking about enabling sun4u only instructions in Solaris 9 patches without doing an arch check at patch install...
I remember being excited when 0.95b came out. It had a parallel port driver, and I could print on these flat cellulose sheets made from dead trees. You young whipper snappers probably don't know anything about that...
You can also build a DB of "first views". If there's a unique serial number on the player, or even the disc, this could then be used for enforcement purposes at a later time. For example, say the disc plays on a player that they later discover is owned by a conference center or a school, etc... That might indicate a "public performance" for which the work is not licensed, therefore copyright infringement.
If the disc keeps popping up on different players, that might indicate a rental disc. If rental discs are issued with a different ID code, it might be used to nail mom & pop rental shops that are buying retail DVD's and renting them, or commercial outfits that are buying discs under restrictive contracts that forbid resale, etc...
All kinds of possibilities when discs phone home. Welcome to the brave new world.
The US diesel sulfur content problem was fixed back at the end of 2006. 2007 model year diesels required 15 ppm or less I believe.
I think there's exceptions for off-road equipment and rail locomotives, both of which run "red-dye" untaxed diesel. But I'm told by a pipeline operator here in the states, that there is no more high sulfur diesel, it's all the same, and some places simply are not legally required to label it ULSD.
My 6.9l had the C6 auto, which was a great transmission, but didn't have the clutch pack in the torque converter and ran a bit hot. Being a three speed, you never quite found the right gear either. The C6 did last 240k miles, and was cheap to rebuild. The whole truck went 258k before my brother-in-law got behind on the oil consumption (valve stem design defect) and it ran it low and turned a ring.
I would have loved to have a manual, but all three were purchased in California before I escaped, and it's almost impossible to buy a manual out there. The 5 speed manual didn't appear until they moved to the short lived 7.3l IDI engine. I will say this, the 5 speed auto they moved to for the 6.0l is a wicked towing transmission. Once they got the software patched up it does a great job holding trailer speeds on downhill runs. Not quite a manual, but not bad.
Actually... The reason was GM's late 70's 350 conversion. They took the venerable 350 c.i. gasoline V8 engine block and converted it to diesel. The results were quite predictable. Cracked blocks, thrown rods, blown head gaskets, etc...
Ford put the first medium duty truck engine in their F-series trucks in the early 80's and had an instant hit. I still miss my smog belching 6.9l. All kinds of fun when some punk in a Honda pulls along side you and fires up the boomity boom music. There's no way their sewing machine motor can beat 400 ft/lbs off the line. Since they wanted me to listen to their music so badly, I used to blow smoke at them. Usually in the driver's window and out the passenger's window.:-)
The 4.88 axle really kills you. You should have had the option of a 4.37 diff., which does a little better. But I have heard from multiple people that the 6.4l just doesn't live up to fuel economy expectations.
I've owned a tired 6.9l IDI, a 7.3l PSD, and currently a 6.0l. The 6.9l would always posted 18 mpg solo with a fresh set of injectors and pump. I never tried towing anything significant with it, but it would drop to 13 - 14 with a slide in camper. The 7.3 has the 3.73LS gears, and gets 17.5 mpg all day at 70 mph. Towing a 10k lb. TT it drops to 9.5 - 10.5 depending on speed and hills.
The 6.0l got a bad rap for some injector defects and software bugs early on. I use mine to tow a 35' bunkhouse 5er and haven't has any trouble at all. The 3.73LS gears are a little tall for mountains, but it does OK. Solo it posts 17 mpg. With a 12k lb. 5er it gets 11 mpg at 70 mph. When I visit California, I have to go 55 mph, and the fuel economy goes up to 12.
I'd seriously consider swapping out the ring and pinion in your rig.
Oddly enough... Depression and Diabetes appear to have some as yet undetermined link. If you're diabetic, you have a high probability of being depressed.
My Dad was a mainframe operator when I was a kid. We're talking early 70's here, but he actually went all the way back to the IBM 1401. I've always had a fondness for the beasts, but no experience with them. Therein lie the problem. They're not at all commodity iron. Linux came into existence because commodity equipment became powerful enough to host such an OS. That cannot be said of z/OS. It simply doesn't run on anything I'm likely to find on sale at Fry's.
How does one gain employable skills with untouchable hardware? (Note: I don't consider Hercules to be a solution. Where's the software?)
The problem is more because California has a 20+ year history of failing to pass a budget and then running out of money every October. This then results in all kinds of political antics that usually get resolved by heaping fees and taxes on the middle class and a budget gets passed just before Thanksgiving. Lather rinse repeat.
Most other states don't have the dual noose of prop 13 and pseudo-socialism around their neck, and actually manage to pass their budgets on schedule most of the time, thereby avoiding the problem completely via fiscal sanity.
Nope. That relies on Carbon-14 production in the upper atmosphere by bombardment of Nitrogen by cosmic rays. This is impacted by variations in the Earth's magnetosphere.
We are releasing large quantities of C-14 depleted carbon by burning oil and coal. But this can be compensated for.
As I understand it, Arnie wants to pay them minimum wage, and then grant them back pay once the budget is passed. That's a whole different calculation, and requires some kind of per-employee escrow account, etc...
If I was a Ca state employee, I'd be pissed. Thankfully, I'm not even a resident anymore.
You forgot that there were more signal lines available, but unused. They had serial in and serial out. The fastload cartridges turned one line around and implemented a 2-bit parallel transfer. Fastload carts also offered a great place to solder in a reset button.
I'd tell you to get of my lawn, but that would just make more rocking chair ruts...

On the upside... There's a Fry's ad on friday.

Interesting read, thanks! (How often do you hear that on Slashdot?)
So 25 billion pounds of lithium carbonate in Kings Valley... I'm guessing at some point in the smelting process there's a:
Li2CO3 + 2H+ -> 2 Li+ + H2O + CO2
Which leads to an obvious CO2 emissions problem. Not saying it's not manageable. Just pointing out a potential problem with non-silicate sources.
Most upcoming highway-speed EVs use advanced li-ion.
Serious question... How many cars need replacing, how much lithium is needed in each, and how much economically recoverable lithium exists here on Earth?
The problem is, they need to keep themselves warm. Once the internal heaters are powered off, the batteries and electronics freeze up.

And from that you will learn why real network geeks use Foundry gear. ;)
Perhaps... But you get to learn their *iron nomenclature. It's almost as bad as Sun slapping "Solstice" on everything back in the 90's...
