PostScript on choosing a thesis font

Following hard upon questions of content and structure is another essential decision related to the thesis: what font to print it in. The obvious choice, based on past form, would be Garamond (the font used in the banner atop this page). It is definitely a more elegant font than the ubiquitous Times New Roman, but it is rather too common itself. Bembo is an older and rarer variant, which I believe was used to print the hardcover edition of The Line of Beauty. Cheltenham Book is an option I am considering.

For ease in reading, as well as general aesthetics, I strongly prefer a serif typeface. Indeed, if there were any apart from Times likely to be on any computer someone would use the blog from, I would use a serif typeface here. As it stands, it will use one of the following sans serif typefaces, in decreasing order of preference: Lucida Grande, Verdana, Arial (a bad ripoff of Helvetica, but very common), and whatever the system standard Sans-Serif is. Because of the font collections included in each OS, Mac users are likely to see Lucida Grande, while Windows users are likely to see Verdana.

Are there any other people out there who check the front pages for a blurb on the font before starting a book? If so, do you have any suggestions?

One final matter typographical: North American Mac users in Oxford, and there are a good many, will appreciate learning that you can make the Pound symbol (£) by hitting Option-3.

More of you should get Skype

Fall Leaves, Wadham College, Oxford

I got lots of thesis reading done today, as well as spending a good couple of hours conversing with friends and family members back home. More friends around the world should install Skype. Since arriving in Oxford, I have spent hundreds of hours exchanging text messages with 126 different people. That said, while an hour or two spent exchanging MSN messages can certainly keep you abreast of what another person is up to, the psychological significance of even a twenty minute phone call seems much greater.

For a conversation between two computers running Skype, there are no fees at all. All you need, in order to use Skype, is a Mac or PC with a high speed internet connection (pretty much any university network is more than fast enough), headphones, and a microphone. There are even Skype compatible phones. The headphones aren’t really required, but if you don’t use them you can get odd echo effects from the 80ms delay that tends to exist for messages between Oxford and the west coast of North America.

While I can use Skype to call normal phones (Canada to the UK costs €0.017 a minute), it always seems like something of an imposition on my part – especially since most of my friends can only really be reached on cell phones. Seeing that someone is online and interested in talking is a useful affirmation of the wisdom of giving them a ring. I haven’t personally been in the habit of leaving Skype running, even when I am at home, primarily because so few of my friends use it. That said, I will make a point of remaining online more often, so as to reward those who take the advice above.

PS. On account of today’s atrocious weather, I was unable to produce a photo worth putting online. Next time I get a good batch, I will backdate one to this entry.

PPS. This ongoing discussion of the moral importance of inequality is highly interesting.

Mica in two new Google Idol contests

My brother Mica has two new entries in the Google Idol video competitions. Partly thanks to strong support from readers of this blog, his video for “Walk Idiot Walk” won a previous competition. This is also documented on Wikipedia.

His two videos that will be in the running are:

  1. “The Jock Rock” in the semi-final of the Pop competition
  2. “I Bet You Look Good on the Dance Floor” seemingly yet to be listed

I will post updates as the status of the videos change. See also Mica’s website.

New voting process

The voting works quite differently from last time. Instead of allowing one vote per IP address per day, it allows one vote per user account per round. They are tracking IP addresses used for account creation, so trying to set up fifty accounts from the same computer will land you in trouble. (Of course, if you set up fifty and used them to vote for the video that you want to lose the round, it might be a highly effective strategy.)

One word of concern: it doesn’t say anywhere on the site that they will not be selling the email addresses used in the signup to every spammer from Nigeria to Philadelphia. As such, I recommend using your most spam-ridden and least important email account to sign up. Last time, they could at least count on people seeing the banner ads each day as they came back to vote. In order to replace that income stream, you have to at least suspect that they are harvesting emails for profit. You cannot just give a fake email address, like when leaving comments on this site, because they will send you an activation code that you need in order to vote.

Snazzy open source video player

Available for PC and Mac, the Democracy video player is free and open source software that can play and save a wide variety of video formats. You can, for instance, save Google Video and YouTube files. That includes all of my brother Mica’s videos. The interface is also a lot nicer than mucking around with web pages: especially since you can download batches of files at once and watch them when they finish.

More information is on Wikipedia.

Imperfect correspondence

In my recent experience, people have a really terrible success rate in getting back to me. This is in cases where a specific agreement is made to exchange some kind of information, usually academically related, via email. I would hazard that I actually provide such information more than 99% of the times that I say I will, though perhaps not immediately. Based on two weeks of tracking, the rate for people who have promised me such information – ranging from notes to paper citations to club information – is a dismal figure of about 10%.

Even among people who I send an email asking again for the information they were meant to provide, the success rate has been no better than 50%. I understand that not everybody is as computationally active as I am, but it is extremely frustrating to be working in a place where almost all academic work flows through some sort of electronic channel, but people’s willingness to uphold basic commitments seems so low.

Hopefully, those rates will pick up a bit with regard to the Reading conference. Some of the things people mentioned sounded very useful and interesting indeed.

Replacement lithium ions

Now that I have realized how useful the wiki could be for storing notes, I have decided to buy a new battery for the iBook. Less than one hour of unplugged time does not mesh well with several seminars or lectures a day.

Having a searchable, durable database of notes is worth the $160 cost of the battery. Also, since I will have two, I can continue to abuse the old battery by recklessly depleting it a third or the way, then charging it again.

Unfortunately, there is no chance of me actually getting it before this Friday’s climate conference in Reading.

[Update: 11 October 2006] I have cancelled the web order for the battery, as it seems like I wouldn’t actually get it until mid-November. I expect Apple is backed up on battery orders because of the Sony fiasco. I will just buy a battery in a shop, either in Oxford or London.

[Update: 31 October 2006] After 214 cycles, the battery seems to have suffered a critical failure. Now, even when apparently 3/4 full it will sometimes fail completely, causing the iBook to abruptly turn off. This is not a calibration issue; I have tried re-calibrating the meter several times.

Thankfully, I will be able to buy a new one in London in eight days.

[Update: 13 October 2008] My original iBook battery has now failed completely. It cannot run the computer for even a fraction of a second, the LED charge display on the bottom of the battery doesn’t work, and the computer often cannot detect that the battery is present.

Protecting your computer

Beaumont Street, Oxford

At least once or twice a month, someone who I know endures a computational disaster. This could be anything from a glass of wine spilled on a laptop to some kind of complex SQL database problem. In the spirit of Bruce Schneier, I thought I would offer some simple suggestions that anyone should be able to employ.

The most important thing is simply this: if it is important, back it up. Burn it to a CD, put it on a flash memory stick, email it to yourself or to a friend. The last thing you want is to have your laptop hard drive fail when it contains the only copy of the project you’ve spent the last month working on.

Now, for a quick list of tips. These are geared towards university students, not those with access to sensitive information or large amounts of money:

  1. Do not trust anything you see online. If you get an email from ‘PayPal’ or your bank, assume it is from someone trying to defraud you. It probably is. Likewise, just because a website looks reputable, do not give it any sensitive information. This includes passwords you use for things like your bank.
  2. Never address email messages to dozens of friends. Lots of viruses search through your computer for email addresses to sell to spammers or use for attacks. If anyone in that fifty person party invitation gets a virus, it could cause problems for all the rest. If you want to send emails to many people, use the Blind Carbon Copy (BCC) feature that exists in almost all email programs and web based email systems.
  3. If you run Windows, you must run a virus scanner. All the time. Without exception. If you run a Mac, run one in order to be sure you don’t pass along viruses to your friends. Both Oxford and UBC offer free copies of Sophos Antivirus. Install it and keep it updated.
  4. Run a spyware and adware scanner like AdAware often. If you are not doing advanced things with your computer, be proactive and use something like Spyware Blaster. (Note, some of the patches it installs can cause problems in rare circumstances.)
  5. No matter what operating system you run, make sure to apply security updates as soon as they come out. An unpatched Windows XP home machine is basically a sitting duck as soon as it is connected to the internet. See this BBC article.
  6. Only install software you really need. Lots of free software is riddled with spyware and adware that may not be removed when you uninstall it. Especially bad for this are some file-sharing programs. If you do any kind of file sharing, the importance of having a virus scanner becomes imperative.
  7. Never use secret questions. If you are forced to, fill the box with a long string of random letters and numbers. If you cannot remember your passwords, write them down and guard them like hundred dollar bills.
  8. For your web browser, use Firefox. Safari is fine, but you should never use Internet Explorer. If a website forces you to (especially something like a bank), complain.
  9. If there is something you really want to keep secret, either keep it on a device not connected to any network or encrypt it strongly. A user-friendly option for the latter is PGP. Whether it is some kind of classified research source or a photo of yourself you never want to see on the cover of the Daily Mail (once you are Prime Minister), it is best to encrypt it.
  10. Avoid buying compact discs that include Digital Rights Management (DRM). Many of the systems that are used to prevent copying can be easily hijacked by those with malicious ends. See one of my earlier posts on this.
  11. If you have a laptop, especially in Oxford or another high theft area, insure it. They can be stolen in a minute, either by breaking a window, picking a lock, or distracting you in a coffee shop. Aren’t you glad you made a backup of everything crucial before that happened?
  12. If your internet connection is on all the time (broadband), turn your computer off when you aren’t using it.

Basically, there are three big kinds of risks out there. The first is data loss. This should be prevented through frequent backups and being vigilant against viruses. The second is data theft. Anyone determined can break into your computer and steal anything on there: whether it is a Mac or a PC. That is true for everything from your local police force to a clever fourteen year old. Some of the suggestions above help limit that risk, especially the ones about security updates and turning off your computer when it is not in use. The third risk is physical loss or destruction of hardware. That is where caution and insurance play their part.

If everyone followed more or less this set of protocols, I would get fewer panicked emails about hard drives clicking and computers booting to the infamous Blue Screen of Death.

[Update: 6 January 2007] The recent GMail bug has had me thinking about GMail security. Here are a few questions people using GMail might want to ask themselves:

  1. If I search for “credit card” while logged in, do any emails come up that contain a valid credit card belonging to me or to someone else? I only ask because that is just about the first thing that someone malicious who gets into your account will look for. “Account number” and similar queries are also worth thinking about.
  2. Can someone who gets the password to my Facebook account, or some other account on a trivial site, use it to get into my GMail account?
  3. Have I changed the password to my GMail account in the last few weeks or months?

If the answer to any of those is ‘yes,’ I would recommend taking some precautionary action.

Oxford from above

Wadham College, Oxford MCR bop

As a recent comment proves, there is at least one thing Microsoft does better than Google: display aerial views of Oxford.

Compare Google Maps, centred on Wadham College, with the Windows Live equivalent: enormously superior.

Here, you can see:

Those pointed out, I should return to the overly loud MCR freshers party, and stop worrying about my ongoing student loan appeal dialogue. People should feel encouraged to list more nice Oxford locations in the comments (with links to Live Local photos).
