Leopard

Filed under: OS X — Erwin @ 2:27 am

I received the Leopard DVD on Friday, shortly after noon, and almost immediately put it to work. Twenty minutes DVD-verification and 45 minutes of actual upgrade time later I’m running OS X 10.5.

Here are my notes such as they are:

  • The default netatalk package in Debian/Etch does not cooperate with Leopard. You can either compile it yourself, if you can figure out how to do that, or fetch it from debian.jones.dk (which appears to be unreachable right now). The actual package lives at /dists/stable/misc/binary-i386/hykrion/netatalk/netatalk_2.0.3-5.0.0jones2_i386.deb. The reason is that Leopard no longer puts up with clear-text passwords and the default package in Debian/Etch doesn’t include uams_dhx.so that implements Diffie-Hellman eXchange, which Leopard will accept.
  • After I carelessly upgraded to Tunnelblick 3.0b5 (I was using 3.0b4) I found that something in 3.0b5 doesn’t play nicely with Leopard, causing it to not set up a default route after creating the OpenVPN tunnel, so I’ve downgraded for now. Maybe later.
  • I am happy to be using Spaces and have already made a list of applications that by default open in specific virtual desktops. Occasionally switching between applications seems to interact a bit quirky with Spaces, but I can’t quite put my finger on it.
  • Thankfully all of my regular applications (Adium, iTerm, Firefox, Thunderbird, Moneydance, MiniBatteryLogger) seem to behave well after the upgrade.
  • I must not have been using cronjobs when I upgraded to Tiger, because I don’t remember that upgrade nuking any crontabs, but I hear that that’s standard procedure. So if you have any, make sure you keep a copy somewhere and restore them again afterwards.
  • I like what I’ve seen of the Time Limits feature in the Parental Controls. It takes fast user switching into account and pauses the countdown when the time limited account is not actually the one in focus so to speak. When you’ve reached your daily limit it still lets you log in but almost instantly kicks you back to the login prompt. When you try to log in outside of the allow time frames it simply doesn’t let you. When you’re logged into an account with a time limit it warns you 15 minutes in advance and shows a countdown. At 1 minute before you run out of time it also gives you an audio warning. All in all, not bad and I’m looking forward to putting it to good use on the family Mac Mini.
  • The Fan Control setup was removed in the upgrade process but a new version was released that is Leopard ready.
  • The Time Machine doesn’t seem interested in my network mounts and I’m pretty sure that in earlier builds that did work. I guess I’ll continue my rsync + Bacula based backup setup for the Macs for now, then.
  • I like the new iPhoto based screensaver, although now I’m tempted to set one up similarly with a network mount that includes all the photos in was-there.com. Something to try another day.

So far I’m happy with the improvements and there are a few things I haven’t even tried yet (the new iChat for instance, although I know in advance I’d never fully switch to it). I briefly glanced at Photo Booth but the backdrop tricks seem to expect a certain kind of background that I don’t have, so the results are less than perfect.

More testing fun tomorrow!

Update: Instead of a non-mainstream netatalk package it’s also possible to re-enable the cleartext passwords with this magical command line incantation:

    defaults write -g com.apple.AppleShareClientCore -dict-add afp_cleartext_allow -bool true

Update: There is a newer version of Tunnelblick, 3.0b6, which appears to work better with Leopard.

Update: Another magical command line that I applied pretty quickly, which turns the 3D dock back into a 2D one:

    defaults write com.apple.dock no-glass -boolean YES

This week’s linkage

How to build your own Sputnik:

“I wouldn’t be surprised if you could build one in a container smaller than a matchbox, weighing about as much as a wristwatch. The components, including a transmitter, battery and the sensors you’d need would probably cost less than £50,” he says.

That’s progress.

Stellarium:

Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. It is being used in planetarium projectors. Just set your coordinates and go.

Looks pretty cool!

Comcast traffic blocking: even more apps, groupware clients affected:

So far, Comcast has been extremely tight-lipped about what’s going on here. The only thing Comcast will admit to is using “the latest technologies to manage our network to provide a quality experience for all Comcast subscribers.” From the look of things, that quality experience doesn’t extend to BitTorrent, Gnutella, and Lotus Notes—and we wouldn’t be surprised to see more applications added to that list.

What was that about net neutrality again? Ugh.

The Evolution of Yahoo! 360:

On Yahoo!’s Q3 Earnings call today, it was announced that we intend to transition Yahoo! 360 to a more integrated Yahoo! experience in early 2008. I want to provide additional information on this news and assure you that we will minimize any disruption to you and our valued Yahoo! 360 community. I also want to assure you that you can still use all the features of Yahoo! 360 until this transition takes place in early 2008.

Translation: We’re shutting down Y!360. This was posted there a week ago and only today I hear about it through TechCrunch. If a tree falls in the forest and nobody is there, did it really happen? Or something like that. 🙂

Printer fun

Filed under: Technology — Erwin @ 8:24 pm

Our Epson Stylus CX5400 (bought almost 3 years ago, it’s been discontinued now, of course) all-in-one printer stopped working when 2-3 weeks ago A wanted to use it for something and even putting new cartridges in place (although the old ones weren’t fully depleted yet) didn’t do any good.

What to do, given that I know little to nothing about printer internals. Pondering this a bit and doing some research, I run across a website called fixyourownprinter.com which sells self-help packages. The appropriate package for our printer is $9.99 (excluding tax or shipping) so we take our chances and order one. If it works, we’ll have a working printer for the price of this, some wasted ink and paper and an hour of our time and if it doesn’t… sending it in for maintenance (if that’s even an option) is surely going to be more costly than just buying a new one, so not much to lose!

Last week the cleaning solution, syringe and a small bit of tube arrive and yesterday M and I sat down to figure this out.

As described on this page (referred to by the instructions that came with the cleaning solution) the ink purge tube had become disconnected. We had to wing it a little because didn’t have forcepts available, although in retrospect we had needle nose pliers somewhere but didn’t think of those. While doing this the spring underneath the cap assembly that keeps it in place came off so we also had to partially take out the cap assembly itself to reattach it underneath and then reattach all of that to the rest of the printer. Fun! This is where some dental floss came in handy! 😉

From there on it was smooth sailing. I applied the cleaning solution with the syringe, we left it sitting for a few hours and then ran the head cleaning routine a few times before running a printer test. It’s nearly back to regular quality so I’ll likely apply some more cleaning solution and then run the head cleaning routine a few more times, but 95% working is a whole lot more than 0% working, right?

This week’s linkage

Verizon Wireless: If you don’t opt-out, we get to share your CPNI call data:

Verizon Wireless has been contacting its customers via mail to inform them of their intent to share CPNI [Customer Proprietary Network Information] data with “our affiliates, agents and parent companies (including Vodafone) and their subsidiaries.” The company says that customers who do not want their CPNI data shared need to call 1-800-333-9956 to “opt-out.” Upon dialing the opt-out number, Verizon customers will be prompted for their phone number, billing ZIP code, and last four digits of their Social Security Numbers (in the case of businesses, their Employer ID numbers).

Whatever happened to opt-in? Anyway, if you’re with Verizon Wireless I recommend you do this.

Cold weather really does spread flu:

At room temperature, they found flu transmission peaks at low relative humidity (20-35%) and again at 65%. It spread less well at around 50% humidity, and not at all over 80%. This parallels the stability of flu virus in aerosol droplets at different humidities, and also the droplets’ ability to remain airborne. At over 80% humidity, droplets containing flu virus themselves fall out of the air.

The effect also happened too quickly to be due to dry air damaging nasal tissue so that it is not as effective a barrier to viruses, which has been suggested as a factor in humans.

But temperature trumped humidity: at 5 °C animals caught flu at humidities that stopped the virus when it was warmer, possibly because sick animals’ noses shed virus two days longer at cooler temperatures.

Record labels to ditch CD singles for USB flash drives:

Universal told The Times this week that by the end of this month it will release USB singles holding several songs, videos and multimedia content. However, it’ll charge around £5 (€7/$10) per stick – around £2 more than CD singles currently cost.

Read the comments for added fun.

US lawmakers’ apology to Canadian:

Members of Congress have apologised to a Canadian who was seized in New York in 2002 by US officials and sent to Syria, where he says he was tortured.

But then… that’s apparently all they did, while Canada (which also apologized, although I’m not sure what they did wrong, given that the guy was grabbed at New York’s JFK) has offered him $10M (Canadian dollars, which is $10.2M US dollars at the moment, ahem).

Apple Tidbits

Filed under: News,OS X — Erwin @ 7:11 pm

Yesterday Apple finally announced when the next version of OS X (10.5, also known as Leopard) will be released, Friday October 26, and within an hour of finding out I’d pre-ordered a so-called family-pack (since we have 4 machines running OS X in the house). Nothing stops anyone from installing the single user version on multiple machines, Apple didn’t put checks in their code to stop you from that as far as I know (and have noticed, ahem), but I guess I wanted to do The Right Thing ™ 🙂

When the previous version came out I waited much longer with the switch, I was holding out on 10.3.9 while Apple was already at 10.4.6, but this time I’m eager to try out things like the built-in backup software, proper support for the iPhone Notes and various other of the 300 new features (obviously not all of them as exciting as that). I’m also curious to try out the improved Parental Controls on the family Mac and hope the Guest Log-In Accounts will be useful for the occasional visitor (right now I have an account that’s locked down using parental controls for that). Browsing through that list I also notice that Terminal finally has tabs! Not that I expect to be convinced to give up my iTerm just yet.

On a related note: Apple announced that it will have an actual iPhone (and iPod Touch, or iTouch as I see it being called) SDK in February 2008. Were they just waiting to see how easily hackers would break through their defenses first, or are they really not quite ready? Having seen the things that developers created without an SDK, I’m looking forward to seeing what they’ll come up with with one.

Counting down now, 9 more days until Leopard…

Identity Theft

Filed under: Humo(u)r — Erwin @ 3:59 pm

Actually, I’m dealing with the opposite here. Someone has mistakenly used the email address that I have with my ISP (that would be the one that I don’t use except to check it regularly to see if anything other than the usual batch of spam was there, like important messages or anything from the ISP itself) to sign up for websites aimed at future college students.

The most recent one was more than just an email-newsletter subscription, it was an account with all sorts of personal information like the person’s name and address, phone number, current high school, etc. I’d like to warn this person (or the parents) that making mistakes like this is going to cause them trouble one fine day, but how do I do that? Calling them up and saying “Hi, I’m a complete stranger that lives in a different state, but I know your child’s name and birth date and what school s/he attends” wouldn’t exactly inspire confidence, I imagine, and they don’t exactly live next door (the fun of cable companies that provide their service in many different states).

Suggestions would be appreciated. 🙂

A little bit of everything.

Amp’d Mobile’s Sordid Remains:

As Hamilton was cleaning out the desks and filing cabinets, he came across some of those excesses in the form of marketing schwag—like condoms stamped with the unfortunate tagline, “Try not to die.” Little did the Amp’d marketing genius who came up with that line know that the expiration dates on the condoms would outlast the company.

Windows Update Brings Down Newscast:

A Pittsburgh, Pennsylvania television station was forced to broadcast its noon newscast from its parking lot on Wednesday because this month’s Windows update wasn’t installed in time. The “major meltdown” occurred during a ribbon-cutting ceremony to celebrate Channel 11’s new facility, attended by executives from Cox Broadcasting, the station’s parent company.

China joins UN censure of Burmese regime:

China turned against the Burmese government last night and supported a UN security council statement rebuking the military regime for its suppression of peaceful protests, and demanding the release of all political prisoners.

5 seconds (if that) of fame

Filed under: Humo(u)r,Software — Erwin @ 9:50 pm

Yesterday morning I came across an article in The Register about Apple preparing some sort of webapp portal for the iPhone and iPod Touch. Since this seemed relevant, I passed that on to the iPhoneWebDev group, to which I’ve been subscribed almost as long as I’ve had an iPhone. Within minutes Erica Sadun, also on the list, followed up, and I thought that that was the end of it.

Then in the evening I got an email, out of the blue, from a former colleague (we worked at the same company about 8 years ago), saying he had come across my name in a TUAW article, where Erica mentioned the rumour and thanked me for passing it on. 🙂

Oh, and that portal is actually live now, by the way.

Math

Filed under: Family — Erwin @ 1:04 am

When you do a subtraction like 13 – 7, you probably don’t even think about it anymore, you just spit out the answer, right? And just to be sure, that should be 6.

A surprised me this evening with a trick that he apparently figured out by himself. Instead of trying to do 13 – 7 in his head, he first subtracts 7 from 10, getting 3, and then adds that to 3, with final result being 6 (one hopes). So more generally speaking he uses the transformation (10 + x) – y == (10 – y) + x to turn a trickier subtraction into an easy subtraction and an addition!

I think that’s pretty cool for a fourth grader (a nine year old), but maybe I’m biased? 🙂
