A Conversation with Human Resources

Human Resources Representative: Good afternoon, Stuart.

Stuart: Hi.

HR: As you may have heard, we have been conducting interviews with certain personnel lately. In the current economic climate, our company is looking to reduce costs wherever possible. This may also, unfortunately, include "right-sizing" in certain departments head counts. In order to be absolutely fair, we are giving the persons whose positions are being considered for right-sizing the opportunity to justify their current positions worth. Do you understand?

Stuart: You're going to fire me?

HR:No, Stuart. "Right-sizing" is not about firing people. Based on your answers to a few questions, your departments head count will be evaluated. This may include shifting of positions and responsibilities, adjustments to salaries, and in some cases individuals may be released from employment. Does this help you understand?

Stuart: I guess so...

HR: Alright, lets begin. According to our files, your present position is Unix Systems Administrator, is that correct?

Stuart: Uhh, yeah.

HR: And what responsibilities, in your view, does your position entail?

Stuart: I administer to the Unix systems, which includes 4 GNU/Linux Samba servers, 8 load-balanced GNU/Linux Apache web servers, and a FreeBSD firewall... Hey, if you're looking to fi.. err, "right-size" somebody, why don't you look at the two NT admin guys? After all, they have much less experience than me; they're just a bunch of paper MCSEs, which just means you memorized a bunch of stuff and passed a test. They don't have any real admin experience, like with a GNU/Linux system.

HR: We'll get to that in just a moment. In what ways would you say your expertise is vital to the continued operation of these servers?

Stuart: Well, I know just about everything there is to know about GNU/Linux and the associated GNU operating system utilities.

HR: Mmmhmmm. In this email from the director of IS, he tells me that the company is considering the elimination of Linux from the environment in order to lower our TCO -- total cost of operation, I think? No, total cost of ownership. He says we are considering replacing these servers with Windows 2000 Advanced Server, running IIS 5. What do you think about this?

Stuart: That's a stupid idea. Winbl... err, Windows is extremely difficult to administer. You have to keep up with new security patches coming out every 2 hours, and on top of all that you have to deal with the Blue Screen of Death every day, and Microsoft charges you like 500 bucks every time you call them.

HR: So Windows is much harder to administer than Linux?

Stuart: That's right. As a matter of fact, if you just got rid of the Microsl... err, Microsoft boxen, you could replace them with GNU/Linux and save some money on the licenses right there.

HR: Explain this to me. If Windows is so difficult to administer, why are the NT administrators able to support twice as many servers, given their limited "real world" experience, and the fact that they are only "paper MCSEs"?

Stuart: Err, they're probably just not doing their job. After all, my FreeBSD box has a 279 day uptime. Their Microsh... err, Microsoft boxen are up and down every week because of security patches.

HR: Yes, the FreeBSD firewall is an interesting topic. We had an outside security consultant come in, and he found that the FreeBSD firewall had not been patched for a vulnerability in a program called "Open SSH". The NT servers were up-to-date on patches, and properly secured. In addition, a large proportion of helpdesk tickets are called in because of issues with the Samba file servers. How do you respond to this?

Stuart: What? Gaah, the OpenSSH exploit was only a local root exploit!! There's no reason to take down a server with almost 300 days uptime to patch it!! And those people just have problems because they are running Windows 2000 on their PCs!! Microsoft deliberately changed the SMB standard to cripple open source competitors!! If the users weren't so obsessed with using their Outlook calendars and their Powerpoint presentations, they could just use Mandrake or something with StarOffice, and everything would be fine!!

HR: There's no reason to get excited, Stuart. These are just questions we have to ask. Now, given that you say Linux is far easier to administer than Windows, is there any reason to believe that if we bring on another NT administrator, he or she would be unable to support the Linux and BSD systems until they get migrated to Windows 2000?

Stuart: No... err, YES. It is easier, but... they just wouldn't understand!! There is a lot you have to know!! It's not just all point and click and all that kiddie stuff!!! It's really hard, you have to be able to compile kernels and edit conf files!! They couldn't do what I do!!!

HR: OK, Stuart, I can understand your anxiety. We'll move away from that subject. Now, is there any possibility that you see for us to use your skills in another position? For instance, would you be interested in earning your MCSE to become a junior administrator when we roll out the new Windows 2000 servers?


HR: Well, that tells us just about everything we need to know. Stuart, your input is of course appreciated, and we will be taking all your comments under advisement. Your department head will be contacting you soon to let you know about any change in your employment status. Thank you for your time.

Stuart: BYE. <slams door>

Re:How about people with pace makers? (4, Informative)

mclearn (86140) | about 12 years ago | (#4400575)

The article states that the device uses the body's natural conductivity. Hence, there should be no issues regarding those with pace-makers.

Re:How about people with pace makers? (5, Informative)

LinuxInDallas (73952) | about 12 years ago | (#4400625)

Pacemakers and other implantables typically communicate with external devices using low power RF signals. It's quite possible that this networking could interfere with operation of the device. There are rumors of airport security x-ray machines causing havoc in some types of devices. It's the responsibility of the medical device manufacturer to make sure an implant meets certain criteria for EMI/RFI but those requirements are not all that strenuous to meet.

How about you use it for electonic business cards. People tend to lose real business cards and an electronic business card would cut down on cost. What if by bumping into somebody you gave them your business card? Or how about even using it as a personal identification system in which when you go to your company it verifies its informatoin w/ the information that you are carying w/ you. I'm sure a security card such as this transmitted by just touch could become useful in numerous applications...

rice_burners_suck (243660) | about 12 years ago | (#4400442)

This looks like an interesting technology, but what about the security implications? Suppose in ten years, everybody carries around a tiny device--the futuristic counterpart to today's cellphones--which acts as a phone, voice recorder/MP3 player, PDA, digital still/video camera, electronic wallet, and even contains the digital keys to your house, car, and whatever. All you have to do is touch the doorknob to your house and it'll read the keys from your device and unlock automatically.

Now ask yourself this: What's to stop crackers from using a root-kit that operates through handshakes to steal information from your electronic device and then use that information to break into your stuff? Is this another one of those technologies that will become totally critical in our everyday lives, and that will also become a huge security problem?

Re:Interesting, but... (1, Funny)

I've seen this sort of thing thing demonstrated years ago on TLC or the Discovery Channel.

The exception was that it was planned to be a device placed in the shoe which would store the information, like a business card's worth of info.

Really, I can't think of a better way of transmitting your public key to someone. Have a sit down with the boss of the family and shake hands. Write your messages on your PDA and send them to the person through IR or with another touch.

Imagine the human-to-human e-mail system or TCP/IP over Homo Sapiens Sapiens; HSS for short. Write an e-mail with a public key attached and it travels from person to person via handshake until it reaches the person who's key is the same and they in turn could decode the message with their secret key.

Damn... maybe I should patent my system.

Your unique conductivity will be added to our own.
You will be assimilated.
Resistance is futile....

Somehow I envision all my personal data being extracted somehow when I step onto a sewer grate.
Or a nimda virus that uses my unwitting conductivity ports for DDOS attacks against others outside my collective.

My dying wish will be to link up with 7 of 9, who is really about 9 of 10 anyway.

Some things to resolve, but amazing potential (5, Insightful)

Problems: Stores might rig their doornobs to download your personal information as you go in the store. Privacy issue. Or someone could touch you, and have all your information stored. Think potential stalkers/criminals/etc. Scary. Of course you could always turn it off, I suppose, but if you forget it's a problem. I assume I'm not the only absent minded human around.

However, there are some interesting possibilities:

A credit card reader could read your body's electrical signal, as it is also scanning the card. Added consumer security. Even cooler would be if each person had a unique electrical signal their body generates, but I don't know anything about that. Either way, interesting.

You could make long distance calls from anywhere, and have the phone read your calling card number automatically when you pick up the phone.

Possibility of electronic "keys" for car/house stored in PDA. Not so good if PDA is lost or crashes, but if you can call the company and say "My PDA is gone - please scramble my house key codes until we can resolve the issue" it might work. Locking the house would be great - simply disable the electronic circuit from the inside and there is no lock to pick. As for someone who tries to crack it while you're out, simply have the system stop taking input for five seconds if it gets a bad signal. With billions of possibilities at five seconds a try, it wouldn't work real well trying to crack it. If you're paranoid, have it take thirty seconds. No more fumbling with keys or those little remote control keychains, either - just touch and open.

Many issues to resolve, but some very cool possibilities as well.

Does anybody else think this sounds just a teensy bit flaky? The article says the connection works through clothing ... "Apparel and handbags have their own conductivity, allowing an electrical connection to a PDA that can remain in one's pocket..." Huh?? 10 mbps using the cloth of my pocket as a conductor??

I have a suspicion that is getting one slipped to them. The closest Google result I could get with "NTT NoCoMo skin" is this article [] about a cell phone that conducts sound through bone and cartilage, enabling you to listen to the call by sticking your finger in your ear.

Uhhh, okie dokie.

Although, I am telling you right now, if we greased our palms with conducting paste, and gripped REALLY hard, we could get down to 100 kOhms in conductance. Then we deal with noise. Now, most of the connecting tissue is stricly low-pass (which is a bitch for high bandwidth issues), and noise is in the millivolts range. To add insult to injury, most of the signal loss will occur in the skin itself, so this application is a really tough one. I think in the lab you could probably rig it to transmit the amount of info in a business card, maybe.

OTOH, detecting a handshake and using that to trigger an IR linkup seems fairly easy.

Congratulations people, you have been reduced to a wire. And a crappy wire at that.

Oh, but to have this on a college exam.... (1, Funny)

Anonymous Coward | about 12 years ago | (#4400564)

Where you can get charged with academic dishonesty not for looking over at someone elses' test or passing a cheat sheet, but for just givin 'em a high five. That's neat.

That could be concidered a very effecient Peer-to-Peer relationship, however, I'm still waiting until I can get 802.11a wired directly into my brain. The idea of it is simply a little disturbing for me, especially when dealing with power regulation. I wouldn't want a simple thing like a business card exchange to become a 'shocking' experience.

Great for trade shows (0)

Anonymous Coward | about 12 years ago | (#4400582)

This was demonstrated at a trade show that I was at a few years back. The idea was that you could shake hands or touch a button and have info d/l straight to your PDA. Having worked a Comdex or 2. this sounds like a great way to gather a ton of info withour breaking your back before the weeks over.

I haven't even read the article, probably wont. Isn't every couple of months there's some startup scam promising some massive jump and paradigm shift in bandwidth? Aren't we about due another one?

Communicable Viruses? (1)

New reason to wash your hands after pissing. Your PDA may pick up viruses left in the static charge of bathroom doorhandles, etc. For serious.

From Japan? (2, Interesting)

zwoelfk (586211) | about 12 years ago | (#4400608)

Doesn't anyone else find it odd that this was developed in Japan of all places? Living there, I don't know when the last time I shook hands with someone was. At least this could be handy for exchanging information with women... because I don't when when the last time I had (physical) contact with a man.
