This paper : "How to be a programmer, a short, comprehensive and personal summary" (PDF) is a good start to answer your question. After debugging techniques, there are wonderful chapters like "how to talk to non engineers", "how to deal with difficult people", how to tell people what they don't want to hear". The author has a very sound view of dev work (more than net/sysadmin) and his concise advice is worth the read.
WHat you're dealing with is only mis-communication. One interesting point is to try to understand how non-techs see us, especially when they ask us something impossible or overcostly. We cherish this nerd culture, but it makes our interaction with the rest of the world somehow diffucult. Our individual value increases if we are also able to implement the NormalPerson interface.
low tech crack :
as far as audio is concerned, you can rip through analog (for instance old CD reader going line in), spill it on the P2Ps, fsck DRM, and nobody would even notice that your soundcard is only half-decent.
I mean, why do they bother ? This is doomed anyway !! Or is DRM only pushed by tech lobbyists whose sole quality is to give a bit of employment to some of us;-) ?
...apparently some closer to the situation in Japan think...
Am I the only one bothering with this ? What has Japan to do with all this ? Japs and Chinese are not best friends are they ? Is it just the writer's subconscious about oriental people that got mixed up ? Or am I missing something here ?

Computing's Lost Allure

Never trust a computer proffesional that doesnt list computer as a hobby.
I strongly disagree.
From my own experience, my computing skills raise when I manage to let computers a little bit out of my life. For in this spare time:
- I can have life, and it makes me stronger to solve what computers are useful to (solving real-life problems)
- I can think about the difficult programming issues I could not solve sitting in front of the machine.
Toplink is becoming JDO

Comparing is not the best way to go.
From what I've heard, Toplink is due to implement somehow the JDO specs in a few months.
Seems they are trying to change the spec (making the "code enhancement" feature optional), since enhancement is not the way they have chosen. And since they are backed by Oracle, their voice has become louder.
Probably there will be two levels of JDO spec : level one for Toplink, level 2 corresponding to JDO as we now know it.
Anyway JDO is the thing all Java developpers have been waiting for, especially those who have tried EJBs : a well designed framework. And the transactionnal cache feature (in some products, like Lido) may lead to excellent perfs for most apps.

Encrypted HD can't be safe, can it ?
Fo example, if it's a PKI, the private key has to be somewhere in the computer (BIOS, HD, ROM, etc.) for the OS to be able to decrypt. So it is very vulnerable.
The computer is a deterministic system, it fully contains all the information needed for automated processing ; usually security is ensured by the externalization of some part of data (password, private key, fingerprint) considered as needed for some processing.
I mean, you wont type your password everytime your OS reads from the HD;-)
BTW NTFS is a first step in the direction you suggest.

on one of the busiest crossroads in Paris (St Germain / St Michel) they had put an automated camera for a while, shooting whenever a car ran a red light. I've seen pretty neat accident pictures;-), but can't find any on the web.
There is a concise chapter on ADO.NET. The author acknowledges the fact that this is the latest in a long line of Microsoft data access libraries but fails to indicate why this one is better.

Roads have had sensors for at least a decade.
Used for different purposes:
- traffic monitoring (accidents, etc.)
- driver information by huge screens on the road, telling how long to this and this direction ; and I find it really nerve calming to know how long it will take and be able to organize (once it only said how long - in distance - the congestion is, which I don't care about) - website for 4 years.
Here we have two type of sensors:
- simple loops, which only give information about the "coverage rate" (that is, proportion of time there is a vehicle on the loop. Funnily, this figure is heavily correlated with the state of traffic and the speed of the vehicles. 0.1 is heavy traffic and 0.2 is congestion. I do not recall exacly the figures but you get the highest throughput for a magic "coverage rate" which corresponds to around 57 kmph (~37 mph).
- double loops are simple loops 1 meter away ; correlating data from the two gives you the time decay between them and so the speed of vehicles, in a more reliable fashion than just simple loops ; in particular with these you can ajust the nominal traffic model with observed speeds so your model integrates real road conditions (snow, rain, saturday night...) and single loops can then give you very accurate information.
On heavily trafficked roads (eg Boulevard Peripherique in Paris) you have a single loop every 400m and a double every 2km AFAIR.
Yeah mayb' you're right.

Sounds like the Netscape scenario : Internet Search will be "embedded" into Longhorn, and if successful, so long Google.
We may have to remember this day when, by saying no to MS, Google has committed suicide.
But there are a few if's in this scenario
- MS search service successful,
- MS OSes still dominant when longhorn released in 2007
