More On the Disposable Tech Worker

fredklein Re:Recycle! (323 comments)

All the workers need to know is how to look up the correct Process and follow their check list. The Process will cover all scenarios and situations imaginable and should never be deviated from.

Sounds like Manna.


"...I replied, "it's a new system they've installed called Manna. It manages the store."

"How so?"

"It tells me what to do through the headset."

"Who, the manager?"

"No, it's a computer."

He looked at me for a long time, "A computer is telling you what to do on the job? What does the manager do?"

"The computer is the manager. Manna, manager, get it?"

"You mean that a computer is telling you what to do all day?", he asked.


"Like what?"

I gave him an example, "Before you got here, I was taking out the trash. Manna told me how to do it."

"What did it say?"

"It tells you exactly what to do. Like, It told me to get four new bags from the rack. When I did that it told me to go to trash can #1. Once I got there it told me to open the cabinet and pull out the trash can. Once I did that it told me to check the floor for any debris. Then it told me to tie up the bag and put it to the side, on the left. Then it told me to put a new bag in the can. Then it told me to attach the bag to the rim. Then it told me to put the can back in and close the cabinet. Then it told me to wipe down the cabinet and make sure it's spotless. Then it told me to push the help button on the can to make sure it is working. Then it told me to move to trash can #2. Like that."

He looked at me for a long time again before he said, "Good Lord, you are nothing but a piece of a robot. What is it saying to you now?"

"It just told me I have three minutes left on my break. And it told me to smile and say hello to the guests. How's this? Hi!" And I gave him a big toothy grin.

"Yesterday the people controlled the computers. Now the computers control the people. You are the eyes and hands for this robot....."

Bitcoin Plunges After Mt. Gox Exchange Halts Trades

fredklein Re:Magic the Gathering Online Exchange (249 comments)

Bitcoin fails 1, 3, 5, and 7.

It is not durable in a practical sense because it relies on a global P2P network to work. Governments have taken their countries off the internet before. How do you spend your bitcoins during civil unrest when you can't access the network?

How do you access your bank account via an ATM when the connection is down? Oh Noes! Any type of money accessed via ATMs and Debit/credit cards is not... um, money?

It is also vulnerable to a 51% attack, which is well within the technological capabilities of many governments.

Get back to me one you figure out what would happen if one group help the majority of US Dollars (or any money)

It is not convenient because it relies on both parties having setup a bitcoin wallet and having an internet connection

A wallet is trivial to set up. And who doesn't have internet access these days?

If I want to buy a used car for 3 ounces of gold, all I have to do is hand the seller the gold and they can verify firsthand that it is real and then I get the title to the car.

That is not convenient because it relies on both parties having setup gold testing equipment. Oh, and don't you need to go online (or to the DMV) to register the transfer?

I've gone to estate sales where there was no cellular or other data service and was not aware of this beforehand. Someone trying to buy via Bitcoin would be SOL, people using gold, silver, or paper money would go on with business as usual.

Where are you buying land that there is no cell service? (Note: not at the property itself, but at the real estate office (or whatever) where you buy it).

Website Checkout Glitches: Two Very Different Corporate Responses

fredklein Re:Same rules apply (303 comments)

So, I guess the whole thing comes down to: When is an online order 'complete'?

After the buyer has both paid for and taken delivery of the item.

You must own a business.

So, what you're saying is, the business can take my money, 'ship' the product (Ground, of course), then, on the last day before it's delivered, cancel the shipping and have it returned to them, all that time keeping my money in their bank accounts, earning them interest, and only then refund me? Bull.

Website Checkout Glitches: Two Very Different Corporate Responses

fredklein Re:Same rules apply (303 comments)

On the other hand... if the price said $3000, BUT the cash register rings up $300, they need not honor the $300 price: if the clerk catches the error, before finalizing the transaction. If the clerk doesn't catch the error --- tells the customer this is what their price is: then the deal is final after the customer pays.

Similarly IF THE WEBSITE advertises $1000, but when you got to checkout, your total shows $100. The customer should expect the store won't honor the $100 price; if their online shopping cart disagrees with the advertised price.

So, I guess the whole thing comes down to: When is an online order 'complete'? When they say 'thanks for your order', and email you a confirmation? (That's what I'd say.) Or when they actually ship? Or when you get the order delivered?

Mathematical Model of Zombie Epidemics Reveals Two Types of Living-Dead Strains

fredklein Re:hehe (163 comments)

Unless they're magic, they have to get energy from somewhere for all that shuffling.


For zombies to move, their muscles must be working. For their muscles to work, they must have a source of energy. Absent 'magic', that source of energy is blood sugar and oxygen, which needs to be delivered to the muscles by the circulatory system. This means zombies have hearts that beat, lungs that breathe, and blood that flows. (So, basically, aren't they are still alive?) So shooting them Not in the head would still result in blood loss (zombies don't perform First Aid on themselves), and would result in 'killing' them. This also means that zombies need to eat something, otherwise they'd all be dead due to starvation in a few weeks. (no food= no blood sugar= no muscles moving)

This is why the 'infected' type zombies are more logical than the original 'magical dead coming back to un-life' zombies.

Yup. Comes down to observer bias, just like nuclear energy. A nuke plant has an accident that results in a tiny leak of radioactive steam (resulting in exactly 0 deaths)? OH NOES!! THE WURST THING EVAR!!!!! But if a coal power plant spits out literally TONS of CO2, ash, soot (and even radioactive isotopes that were in the coal!), and that's a "Meh".

Sinkhole Sucks Brains From Wasteful Bitcoin Mining Botnet

fredklein Re:Kill the zombies (203 comments)

DUI, per se, that is, driving with a BAC over a certain number, is not harmful. Getting into an accident is harmful. And there is some evidence that people who DUI have a higher chance of getting into accidents.

Of course, there is just as much evidence that being fat/out of shape due to poor eating/exercising habits is harmful. For instance, it takes real time and money to send an ambulance out when you get a heart attack (caused by cholesterol caused by poor eating). Government mandated diets and exercise regimens for everyone!! And the cops should have the right to warrantlessly search your kitchen to make sure you don't have unhealthy food!

Ask Slashdot: Speeding Up Personal Anti-Spam Filters?

fredklein Re:spamassassin (190 comments)

I see you've never had your server compromised.

"The certifier contacts the sender and demands an explanation. If sender was hacked, they fix the security hole and tell certifier they
did so. If spam was not spam, or a misunderstanding, they explain."

A hacked server might result in the revocation of the certification (and thus the UN-certification of all the emails sent by it), but the company can simply re-certify (with a new key pair).

And of course nobody can spoof an email header or perform a Joe Job.

What's what the Public-key cryptography is for. No email can pretend to be from your server, unless it has an encrypted header encrypted with your private key. Which is, you know, private.

These are just two obvious holes. There are certainly more.

Actually, they're not holes at all.

fredklein Re:spamassassin (190 comments)

Just switch over to Email Certification.

Long story short, everyone who wants to send Certified mail has to be 'certified' by their ISP. (UN-certified mail would still be possible, if
you wish.) Getting certified is nothing more than providing enough information to positively identify you, and costs a nominal fee.
In return, you create a public/private key pair, and give the public one to the certifier. The private key goes into your email server, which
adds some headers to each outgoing email. One of these is encrypted with the private key. When someone with a certification-compliant email
program receives a certified email, the program reads the headers, connects to the certifer's certification server, and downloads the public
key. It then uses the public key to decrypt the encrypted header. If successful, it proves that email came from the specified server, and no one

If you get spam, your email client has a big 'report certified spam' button. Click it, and an email is auto-launched to the certifier of the
sender. The certifier contacts the sender and demands an explanation. If sender was hacked, they fix the security hole and tell certifier they
did so. If spam was not spam, or a misunderstanding, they explain.

If, OTOH, the sender does not reply, then the certifier revokes their certification, and from that moment on, all their (the senders) emails are

What if a Certifier themselves is 'evil'? Well, it's certainly possible to have blacklists like they do now, but, instead of blacklisting IP
addresses, which get re-assigned and cause trouble for their new owners, it would be evil Certifiers that get listed and blocked.
Eventually, it'll reach a point where any spam that is sent out will get the sender 'de-certified' almost immediately. That means everyone else
probably never ends up seeing the spam at all (depending on how their clients handle un-certified emails. Most people will probably auto-trash

However, white lists are still possible. If you like getting emails from a certain un-certified sources, just white-list them, and you'll
continue to get them. You can also use challenge-response or keyword set-ups for people sending you un-certified email.

By proving who sent the email (or, more precisely, which server did), Email Certification can hold the server owner responsible. If they send
spam, they get de-certified, which means in all likely hood, they lose the ability to email anyone at all. Spammers who can't get certified
can't send emails anyone will see.

A New Spate of Deaths In the Wireless Industry

fredklein Re:Tie off (247 comments)

At the same time, if the job will take an hour when proper safety measures are followed but if you take more than 45 minutes, you're fired, the fault lies with management. It's not uncommon for employers to pay lip service to safety but then structure things to assure it will be ignored.

A simple letter/email to your boss with pointing this out ("safe practices take one hour, minimum, you say it must be done in 45minutes- are you telling me to be unsafe?"), and requesting a (written) response usually sort these matters out. None but the stupidest manager will put their job on the line by stating in writing that you must not follow standard safety practices. And the ones that do... you sue.

How to store massive amounts of video on the cheap

fredklein fredklein writes  |  more than 3 years ago

fredklein (532096) writes "I recently started contractor work at a relatively small video conversion business. They accept jobs from the public as well as various photo studios and photo labs. They digitize everything from photos to VHS to old reel-to-reel film, putting it on DVDs. However, in the process, they end up with at least two DVDs to archive- one of the raw video, one of the edited. I'd like to move them to a completely hard drive based system, where the incoming jobs are saved right to video files, edited, then stored, all without being burned to DVD (except for the customer's copy). This, of course, requires massive amounts of storage. 20 jobs a day, roughly 5Gig for the 'raw' video (DVDs are 4.7Gig, but...fudge factor), another 5Gig for the edited, means about a Terabyte a week to store, or 50+ Terabytes per year. And that's not mentioning backups. I'm looking for any ideas on how to handle such a huge amount of video data, preferably while keeping costs at or below what the original DVDRs would have cost."

Grad student suspended after pro-gun-rights e-mail

fredklein fredklein writes  |  more than 7 years ago

fredklein (532096) writes "A Minnesota university has suspended one of its graduate students who sent two e-mail messages to school officials supporting gun rights.
"Hamline University also said that master's student Troy Scheffler, who owns a firearm, would be barred from campus and must receive a mandatory "mental health evaluation" after he sent an e-mail message arguing that law-abiding students should be able to carry firearms on campus for self-defense."
When informed that suspending him violated the school's freedom of expression policy, the University changed their tune: Now they claim he's being suspended because of "anonymous allegations" they received, and they can't tell him (or the press) what those allegations are, or who his accusers are. With all the talk of 'Big Brother' throwing people into detention centers without knowing the charges, are we overlooking 'Little Brothers' closer to home?"
