Let’s keep in touch!

By Louis-Dominique | Filed in General

Recently, I’ve stumbled upon this little piece of wisdom: “stop pretending that you are going to keep in touch with someone if you don’t really mean it.” The context of this advice was when you run into old schoolmates or workmates, chat for 2 minutes and then exclaim: “let’s keep in touch.”

I find myself in agreement with this advice.  When someone tells me “let’s keep in touch”, I take the statement at face value: that person really intends to keep in touch.   Now, I realize that people often say things they do not mean.   They say things like “Wow! I love your new hairdo.” while thinking “Who’s your hairdresser?  A ferret?”  So it is quite likely that “let’s keep in touch” is a socially appropriate thing to say but that there is no real intent behind it.  As likely as it may be, that’s not the way I take it.  I take it as an expression of real intent.

I’m not the kind of guy who readily keeps in touch with people. So I’d find it dishonest on my part to let the person who says “let’s keep in touch” believe that there’s any substantial probability that we will, in fact, keep in touch.  So my reply to “let’s keep in touch” is usually to point out how in actuality it is unlikely to happen.  And then the reaction I get is similar to the one I’d get if I had just said “away from me, you leper!”

When it comes to securing the data I have on my computers, I take the task seriously. I use Ubuntu and Windows on my laptop.  The Ubuntu installation is fully encrypted.  There’s a performance hit but I feel pretty sure that if my laptop is ever stolen or lost or needs service by a third party, I won’t be at risk of getting sensitive information stolen.  The Windows side is not (yet) encrypted but I do not use Windows intensively or for sensitive tasks so I’m not very worried about that.

Now, when I talk to other people about this, I’m told that I’m paranoid.  If I’m not keeping porn on my laptop, I have nothing to worry about.  If my laptop is stolen, no one will take time to look for banking information.  The techs who perform service are interested searching for porn, not financial details.  Basically, I’m told I’m worrying for nothing. (Now, logically-minded readers will have figured out that the flip side of this bad reasoning is that if I do worry about people snooping through my hard disk, then it means I must have porn on there.)

Well, well, it turns out that a Sky News undercover investigation that technicians do indeed look for financial information on the laptop they service and they try to use it to break into banking accounts.  OMG!  Who would have thunk?

The solution against unscrupulous technicians is to give them a clean drive: a drive which contains no sensitive information.  My point here is not that encryption is the solution but that unscrupulous people are indeed after your financial information.  Encryption is part of the arsenal of tools to protect against that.

Pride is strange

By Louis-Dominique | Filed in General

I do feel angry about things, happy about things, annoyed about things, sad about things. Pride, however, is not natural for me.  It is not that there is nothing I could point at and express pride about.  I can conceive that someone might feel pride if their hard work is fruitful. I can also conceive that someone could feel pride in someone else’s accomplishment to some extent.  I mean insofar as one can be instrumental in someone else’s success.  I can conceive of these kinds of pride even if I don’t usually feel pride. But some kinds of pride just plain seem silly.

“I am the proud owner of [brand name gizmo].”

Say what now? You walked into a store and bought your gizmo. Is this some sort of achievement to feel proud of? Are you also proud of being able to walk without drooling all over yourself? How about “I am the proud owner of a banana.”

“I am proud to be [ethnic group or nationality].”

Bravo! Luck made it so that you were born with that ethnicity and nationality. Now, if you want to feel even more pride, grab a coin, flip it, and scream to everybody nearby that you are proud that you got head or tail. For more variety, grab a die instead of a coin and wear some sexy lace.

Sometimes national pride is expressed as:

“I am proud to be [nationality] because [my nation] did [something awesome].”

Now the funny thing is that the same person who asserts the above won’t usually want to admit “I feel ashamed to be [nationality] because [my nation] did [something terrible].” In this case, pride is axiomatic. It has been drilled into the individual from a young age. No amount of disconfirming evidence is able to overturn this pride. It is especially bizarre when the “something awesome” part of the formula consists of some event which happened before the prideful person was even born. Pride for something you contributed to? Ok. Pride for something you cannot possibly have been contributing to? Say what? You might as well feel pride for your neighbor’s doings then.  Or you might as well feel pride for the imaginary achievements of imaginary persons: “I’m proud that Luke Skywalker was able to blow up the Death Star.”

Strange rationalization

By Louis-Dominique | Filed in Commerce

I’ve been researching espresso machines a bit some months ago with the intent of buying one. (I’ve eventually decided against it.) I found that good machines are expensive. I also found a fairly peculiar bit of rationalization in discussion forums.

Dear Cessna: Correlation is not Causation

By Louis-Dominique | Filed in Commerce, Media

Cessna has put out a piece of propaganda containing this gem:

Study after study shows companies operating business aircraft outperform competitors that don’t.

The implication is: buy a business aircraft for your company and you’ll outperform your competitors. Dear Cessna, is this really the logic you want to espouse? Has it occurred to you that maybe causality runs opposite to what you imply? Could it be that companies which are successful due to other factors are enough money to spend it on planes and on frivolous purchases? Does this seem possible? Maybe?

Yeaaahhh, I thought so.

Airbag safety

By Louis-Dominique | Filed in Technology

I have to admit, sheepishly, that I have not been paying good attention to the fact that airbag technology in cars requires changes in behavior. I’ve been reading up on it a bit and came to that part where they advise passengers to avoid riding with hard objects in their lap. I can’t count the number of times I’ve violated this rule and I shudder I the thought of what would have happened if an airbag had deployed.

“You love laptops! How about having one embedded in your face?!?”

Yes, yes, I know. Even without airbags it is dangerous but airbags make it much more dangerous.

The Smell of Zombies in the Morning

By Louis-Dominique | Filed in Nonsense

There was some stupid ad on TV this morning. As I am wont to do, I parodied it. I made up some nonsense slogan with the phrase “zombie pus”. Debbie immediately corrected me, arguing that zombies cannot have pus because they are dead. Technically they are living-dead but she’s probably right. I did a bit of research on Wikipedia and found that corpses have cadaverine or putrecine. So I guess that’s what zombies have too.

Putrecine: eau de zombie, by Chanel.

In-flight entertainment

By Louis-Dominique | Filed in Nonsense

When I opened my bag of peanuts on the flight back home last weekend, one of the peanuts flew right between my legs. I reached for it but it just kept sliding further and further. I stopped when I realized that from the perspective of the other passengers I must have looked like I was trying to give myself a rectal exam.

Fixed my power supply

By Louis-Dominique | Filed in Technology

“It is a poor craftsman who blames his tools.”

Let’s get this one out of the way. I’m not a craftsman, so there.

The power supply on my laptop gave out while I was in Taiwan. I quickly found the problem was located in the wire going between the power supply and the laptop. The internal sheath had broken so the wires made a short-circuit. I tried repairing it while I was living at Dharma Drum but that proved quite difficult due to the lack of proper tools. The only soldering iron available on the mountain was of terrible quality. It was barely getting hot enough to melt the solder. Moreover, there was no new solder available on the mountain. I eventually was able to reuse the old solder already on the board (gaaah!) and made some sort of temporary repair. I considered going into Taipei to get parts to finish the job properly but I gave up on that idea. It turns out that during my last few days at Dharma Drum my temporary repair gave out and I had to keep the wires in place with a piece of plastic tape. (Eeek!)

I came back home two days ago.  Yesterday, I bought heat shrink tubing.  This morning I gathered my tools and was able to finish the job in about 10 minutes.  It was a real pleasure to work with good tools.  No doubt someone adept at soldering would laugh at my work but… well… the power supply now works and I’m not pretending to be a craftsman.

I’m quite pleased with myself.  When I bought the laptop, I did not get an extended warranty.  I took the one year warranty and made the bet that if something were to happen I would probably be able to fix it myself.  It looks like I’m going to win that bet. (I’ll only win if the laptop is still working fine after 3 years of ownership.)

The Internet has proved indispensable in this process.  First, I found this guide on how to fix a power supply cord.  Sri1ram’s comment about using a blade to crack the glue holding the case together was very useful.  Second, I found Keith’s blog post on refitting a strain relief.  Before I found this post, I thought I’d get a new strain relief or I’d finish the job without the strain relief.   The problem was that I was unable to rethread the cable through the strain relief.  Keith had the same problem and solved it by drilling through the strain relief.  I got my wife’s Dremel out and did the same: it worked nicely.

Coders without shame

By Louis-Dominique | Filed in Software

I’ve been running into a good deal of bad computer code lately.  Here’s an example from an actual tutorial.  I’ve renamed the variable to protect the shameless:

if (count == 0) return false;
return true;

Why not this:

return (count != 0);

There are some god-forsaken languages in which returning the evaluation of a boolean expression is not valid (e.g. the creeping horror which goes by the name Open Office Basic).  C and C++ are not among these.   Yet, I’ve been running across a good dozen cases where the coders did not realize that.

In case someone would like to object: I know it is possible to just return count and let the compiler do an implicit conversion to bool but an explicit test makes the code clearer.  The additional “if … then” does not.
