A long time ago, C++ MVP Bruno van Dooren started a new job. He blogged about why the procedures they follow are important:

We make medicine. Ours is injected directly into the bloodstream of patients who are already weakened by their condition. It goes without saying that there is absolutely no room for making mistakes. Any possibility for error has to be eliminated.

Most of us don't have stakes quite that high, but we work in environments where mistakes should not happen. And yet, they do. And more importantly, every once in a while a cascade of mistakes (I typed something in error, then I didn't run the tests because it was such a small change, then someone else just copied without checking etc etc) means that something bad actually happens "in production". Our procedures are designed to prevent this - the bad cascade happens when people don't follow procedures.

I've found that everyone sets procedures aside some of the time. Heck, if you have something wrong in production at 7pm Friday night, you don't leave it like that because you can't raise a second person to sign your release form, you fix it, and you do the release form Monday. And some procedures seem to be always ignored, which is a sign (when I have my I Own The Company Hat on) that they should be changed. But what interests me is that some people almost always ignore procedures, even good and helpful procedures that everyone else follows. Why would that happen?

I don't have a lot of data on this. People don't like to sit down for an open and honest chat with their boss about why they don't do things the approved way. In fact, most folks who never follow procedure go to some trouble to make it look as though they do follow it. What's more, once I become aware that someone routinely ignores a procedure and hasn't come forward to suggest it should be changed, our opportunities for conversation tend to dwindle, since they're usually busy with a new employer :-). But it seems to come down to one of three things:

  • The procedure takes a little extra time. The person is selfish or lazy or both, and skips that time. The pain the procedure saves is not their own, so they would rather have the time to either do other work and look very productive, or relax at work and have more free time. Sometimes this is a cue to me to reduce the time that the procedure adds, but not always. If you had a developer who took the read only flag off all source files so as not to be bothered with the time it takes Visual Studio to check those files out on edit, would that be OK?
  • The person doesn't know or understand the procedure, or doesn't believe that management will change the procedure if they come forward and suggest a better way. This is why we all suffer through endless "presenting the new procedure" meetings. How else can you tell people? How else can you make people believe? Thing is, I don't know anyone who was actually convinced by a "presenting the new procedure" meeting. I do better by following it myself (tough, because for many tasks in the firm I only get near them in those emergency "I'll do the forms tomorrow" situations) and by paying strict attention to whether others are following. I also need to be more transparent about "presenting the new procedure that was changed because X convinced me this new way is quicker but still prevents errors".
  • The person has discovered a way to do the tasks that is quicker or easier, and still prevents errors, (or maybe that prevents more errors, or whatever) but actively doesn't want the rest of the firm to know it. A sort of "I'm all right Jack" approach that makes that person more productive and perhaps more promotable, but does the firm as a whole no service. I often find out about this only long after the person has "left to pursue other opportunities" since hoarding information and increasing your personal success only are not paths to promotion with me, and this behaviour tends to show up consistently in many things the person does.

Of the three, the hoarding one is the hardest to deal with as a manager. Believe me, you will get more gold stars for having the idea that made your whole department faster than you will for being the fastest in your department. Even if, after your new procedure is implemented, you are somehow second fastest, I will know whose brain is saving/making me money.

So you have your app on Vista now and it's working great. It needs to elevate maybe? Or part of it does? And do you cringe a little when you see that An Unidentified Program Wants Access To Your Computer super-scary version of the UAC consent prompt? Would you like to stop being called Unidentified Publisher? Well then you need to sign your application. But how do you do that? How much does it cost? Isn't it hard?

I seem to only have questions in this particular post. Well John Robbins has answers. Check it out. Try it. Let me know if it worked for you.

This fall there will be a PDC. Yay! What will it be about? Some hints are starting to emerge. I predict you will hear the word Cloud a lot. I predict things I blog about pretty regularly will get some serious coverage. I predict I will be there. That one's a sure bet actually ... I'm registered and everything.

Yeah, I know, LA again, but hey! It's the PDC! How bad can that be?

I watch a lot of videos. Technical interviews and webcasts, mostly. I'm not much of a YouTube person. Channel9, DNRtv, the DVDs with all the TechEd sessions on them, that's what I watch. And I watch on planes and in hotel rooms, to pass the time, or because there's one specific thing I want to learn. But I am an impatient person. Especially when I'm alone, I just cannot go slow. So I love that I can speed videos up with Windows Media Player.

It's not a simple option to find. You click Now Playing, then Enhancements, then Play Speed Settings. And presto, you control your impatience level:

I generally live at 1.4. This gets you through a 1 hour video in 43 minutes with really no loss of understandability. I might slow it down to 1.0 during a demo if I want to take notes and capture the code or the steps as the demo proceeds. I move up to 2.0 if the person is explaining something I already know. This is one way to make that huge pile of stuff you are trying to catch up with just a little more bite sized. As well, because you really have to concentrate at 1.4, I don't do that continuous partial attention thing where the video is playing but I'm checking my email, answering a few things, IM-ing two people and the hotel room TV is on CNN all at the same time, and then -surprise!- I can't really remember much of what I just watched. By really really watching for half or 3/4 of the time, I really learn what I set out to learn. Works for me.

I mentioned in an earlier post that applications with manifests that require Administrator privileges will show up with an overlay icon of the shield on their exe icon in Windows Explorer. Applications with manifests that deny needing Administrator privileges will not get the icon. What about applications without manifests? Well, among other things some Vista heuristics come into play. I found some really old executables (15 year old games) and did a little experiment. Obviously these are manifestless apps. I copied Tetris.exe and renamed the copy Setup.exe. That's all I did. The timestamp is still unchanged. But there's a fairly obvious difference as a result of the rename:

If the file name contains Setup, Patch, or some other magic strings then you will get the overlay and you will be prompted for elevation consent when you run it. (If you're curious, Tetris plays just the same elevated.) Then something fun happens. After you run a file called Setup.exe, if your program files directory is unchanged, your registry is unchanged, your System32 directory is unchanged etc, something is probably wrong. Well, not if you're just playing Tetris, but if the plan was to install something, there's a good chance it didn't install. So Vista says:

If you let it try again, it actually uses Group Policy to store extra information about this application - including whether it needs to elevate or not, should be lied to about Windows version, and other settings you can find on the Compatibility tab of the properties:

Why do you care? You care if Vista has wrongly guessed that an app of yours needs to elevate, and prompts you every time. Understanding these heuristics gets you closer to being able to clear away that overlay icon for your not-administrative-at-all application.

How can you avoid the UAC prompt for applications you frequently run? Well, you could turn off UAC entirely, but that's a bad plan. There are two ways: one is realistic and feasible, and one much less so.

The less feasible one is that you could re-enable the Administrator account (not just some account you happen to have that is in the Adminstrators group, but the actual Administrator account) and log on as that. Pretty much everything you do will be elevated and you won't be prompted about it. But I don't want to do that. I want to log on as me. Plus, I kind of want to control my prompt-noprompt life, or we're right back to malware using my powers without me knowing.

So here's my solution. Get yourself an elevated command prompt (Start menu, spot a command prompt shortcut, right click, Run as Administrator.) Consent once and for all (till your next boot) to elevating that prompt. Now everything you launch from there is elevated, no prompt. Don't believe me? Try regedit. Try notepad. Then try, say, editing your hosts file with that notepad. Cool, no?

Leave the elevated command prompt open, and use it whenever you want to do something elevated. No prompting. You have to type the name of the app (Visual Studio is devenv, which you will care if you're still using 2005.) But pretty painless.

If you've ever watched Star Trek: The Original Series you know it had a trope or a meme where an "away team" would beam down to the planet and suddenly one of them would be killed. Usually vapourized or dragged off by a yeti or somesuch. And as my four year old once said to me "Red people fall down. Not red people don't fall down." This is also known as the redshirt phenomenon. To this day, when I see three main characters (on any show) plus some guy we've never seen before, someone is sure to call that guy out as a red shirt just as the suspenseful music starts to rise.

Well, Matt Bailey has run the math. Are red-shirted crewmen more likely to die than yellow or blue shirts? Indubitably. But - is it good news or bad news, redshirt-wise, if the episode also features what I've always referred to as Kirk putting his boots on, though strictly speaking he does that after the plot point Matt refers to as "meeting" alien women. See how some solid data analysis and well chosen visuals can truly illustrate the redshirt phenomenon on Star Trek, at least for TOS. The powerpoints alone are worth the click.

Have you seen the Deep Zoom example with the Hard Rock Cafe artifacts? It's pretty darn cool. If you don't have Silverlight and would like to see why it's cool, there's a video on the Mix blog. But I love the zooming into Virtual Earth example I was just sent. It's a CodePlex project, so you can be part of it. It can take a while to load so be patient. I showed it to someone who said that Google Earth did that, but requires downloading and installing an application. If you already have Silverlight, you don't need anything else to use this. I like that.

I've been carrying this link around for a while and it seems like a good time to share it. Rico Mariani knows a LOT about performance and why it's important. And he knows that many of us no longer care. We trust optimizers and runtimes and frameworks and auto-caches and such to take care of things for us. Sometimes, we're right to do that. Other times, we're not. Thinking about games will naturally make you think about performance.
