Notes from the Meritocracy Factory

Blackboard – Test Prep – Just Following Orders – An Evil Essay – NYTimes.com

The author, who has an SAT-prep-firm, took the test in order to see how essays are graded. As an experiment, he wrote the most morally evil essay he could, praising Nazi eugenics. The official SAT rules don't talk morality, promising high scores to an essay that,

effectively and insightfully develops a point of view on the issue and demonstrates outstanding critical thinking, using clearly appropriate examples, reasons, and other evidence to support its position.

And, indeed, he got high marks.

I am sure this explains something, but due to the low quality of the reasoning in his work while in government I am loath to say that this something is John Yoo.

All SSD Drives Are Far From Equal

I had not originally planned to consider buying an SSD drive for my new laptop. There are lots of reasons not to, including the high price, and the relative immaturity of the technology. (The relatively low capacity doesn't bother me much, I've been living fine with a 40GB drive on the current machine.

But three things have led me to consider an SSD: it's standard on some of the machines I'm thinking of; it's not as expensive an upgrade on the others; and the T400s uses 1.8” drives, which I gather are substantially slower than the standard 2.5” disks found in most laptops. Indeed, since drive speed is in substantial part a function of rotational speed it only stands to reason that for any given number of rotations per minute, a disk with a smaller radius will move less information past the read/write point (2πR will be smaller at its greatest point, and the mean will be smaller too).

Thinking about SSDs led me to this marvelous article at AnandTech, The SSD Anthology: Understanding SSDs and New Drives from OCZ. It may be more than most people want to know, but the takeaways are clear:

  • Lots of first-generation SSDs look great at first, then work poorly. Their performance “degrades.”
  • Benchmarks of new laptops with SSDs in them that in any way rely on hard drive performance cannot be trusted unless the test suite has been tweaked to fill up the SSD with data before the testing begins.
  • SSDs vary enormously in quality. The really good ones are insanely expensive.

It also seems that the Lenovs and probably the Dells (at least for their more expensive choice) use Samsung SSDs which get relatively horrible initial benchmarks compares to the leaders, but it seems don't degrade as much as some others.

The sensible thing to do would be to get a conventional disk, and maybe upgrade in a year or two if prices get sensible. But some of the laptop makers do give you a break on prices, so that's less obvious than it might be. Plus, to the extent I'm considering the T400s, the 1.8” form factor may severely restrict the update options. At present almost all the SSD drives on Newegg are 2.5” form factor drives.

I suppose I'm overthinking this, but I enjoy it.

Laptop Search (cont): Dell E4200?

So, with the help of a colleague's email, I figured out which Dells I should be looking at: the E4200 and E4300. The reviews of the E4300 don't make it look that good; the E4200 gets a better press, although most of it in more general circulation magazines than in the sort of fanatic's web page I tend to trust.

The E4200 with most of the trimmings — said to have many internal components in common with the Lenovo X200 (not X200s), although a somewhat inferior casing — is a 12” laptop with decent battery life, a 1.4GHz Intel Core 2 Duo ULV SU9400. Despite the low-power chip, the Dell has a better benchmark (PCMark Vantage 3582) than the Lenovo X301 (1.4GHz Intel Core 2 Duo, PCMark Vantage is 3157) although I worry the test may have been affected by using a new SSD. The Dell apparently weighs under 3lbs even with a six-cell battery (2.2 lbs with the 4-cell; Dell is annoyingly coy about about the weight with the six-cell version.) There are fewer ports than the Lenovos, but probably enough for my needs.

Prices for new ones are outrageous — I just configured one for $2335 which is more than the better, if heavier, Lenovo. A similar E4200 is available refurbed for just over $1300 with external DVD, which is notably less than the Lenovos.

This is probably the closest thing to a modernized Inspiron 300m. Is that what I want? The refurbs are mostly black, but there's also a red one.

Correction

I wrote “previously” that my laptop search is now in the decision phase.

Make that “the indecision phase.”

I will certainly delay until I get home next week.

The Hunt for A New Laptop Continues

My laptop search is now in the decision phase. It's fairly clear that I've not only passed the point of diminishing returns on the scouring of the online reviews and benchmarks, but that it is fast becoming a distant memory.

I've more or less narrowed the choices to the Lenovo X301 (refurb) or the Samsung X360 34P (do they do refurbs?), with the Lenovo T400s (refurb) an outside contender — although it has a bit more weight, its processor benchmarks are about double the other two.

As between the X301 and X360, the Samsung weighs less and seems to have a much better battery life; despite a slower clock speed the Lenovo may be a little faster (although the T400s blows them both out of the water). The other benchmarks I can find are broadly comparable. The Lenovo has an unparalleled reputation for standing up to mistreatment; it is hard to get a sense for how sturdy the Samsung is, other than it's not flimsy.

The Lenovo X301 has a slightly smaller screen than the Samsung (and the T400s has the biggest); the Samsung comes with a bigger SSD for the money (not that I really need it). The Lenovos have optical drives; the Samsung doesn't. The X301 lacks the media card reader and Express Card slot found on the Samsung. (The absence of a docking bay for the Lenovo is not something I care about, as I don't use those.)

Here's a table with more details:

Now how do I decide? Not to mention that given the existence of substantially cheaper and adequate — but not as light or as powerful — alternatives it seems a lot of money, even for something I'll probably use frequently over the next several years.

I wish I could see them before buying…

The Hunt for a New Laptop Begins

I have spent a chunk of the past few days looking at what I call “laptop porn” — enthusiast reviews and critiques of new laptops. Because I can't put off buying a new one much longer.

My trusty nearly five year old Dell 300m is in its death throes — not only is the body a bit damaged, and the battery good for only about 20 minutes, but the machine's 1.4 Ghz Pentium M chip will no longer go over 599 Mhz. I've turned off speedstep in the BIOS, put the power settings to their most greedy, I've downloaded various utilities to make sure the fan cools it (it's getting hot under there), and the chip is asked to give its all. To no avail. It's a slug. It's slooow. And I worry it may decide one day to slow itself further. So it's got to go.

I use my laptop a great deal, both on the road and in meetings at work, so for a combined birthday and 20th anniversary gift, I'm going to get a good one. But what is that exactly?

I thought hard about getting an ultralight Atom-powered machine. My wife's MSI Wind is a wonder of portability. It doesn't feel as slow as the specs suggest it should given the Atom chip and the 2GB RAM limit imposed by Microsoft. I hate the MSI keyboard because the “.” key is in the wrong place, but some competitors don't have that problem. But the deal-breaker, I've decided, is the screen just isn't deep enough — you just don't get enough lines of text on the screen to work well with a footnoted legal document.

So I'm going up a size for a bigger screen and a speedier computing experience. I still want as light a machine as I can afford, because airports are not getting any more convenient (have you seen what they did to MIA??? but I digress). That said, I don't want one that is flimsy and won't stand up to the abuse I seem to subject laptops to. I need a fullsize or very-close-to-fullsize keyboard so I can touch type. I figure, might as well get a core2 duo, so it will take everything I throw at it, but I don't have to have the very fastest clock speed. I won't play games on the machine, so I don't need a superfancy graphics chip. I will need an optical drive, but not every day, so it can be external, although a very light bulit-in would be nice. I want lots of ports, but don't need HDMI output.

It turns out that most of the brick and mortar shops that stocked the kind of laptop I am looking for either don't exist any more, or don't stock them any more. So I'm going to be even more dependent on reviews than for previous purchases. Being risk-averse, that tends to push me to established brands like Dell or, to my surprise, Lenovo — an idea planted by a commentator on my earlier post on this self-indulgent subject, It May Be Time for a New Laptop.

There doesn't seem to be a Dell available right now that meets my specs and gets good reviews, although I find their site hard to use and may have missed one. The closest might be the Adamo, but it seems to be glitz over performance and weighs 4lbs without an optical drive. (And before you ask, I'm a PC, not a Mac. I run wordperfect.)

The Toshiba Portege R500 & R600 have very impressive specs and low weight, but the reviews have scary words like “flex” and “loud fan”. The review of the Fujistu Lifebook P8020 didn't make it sound attractive at all. T

I need to learn about Sony's offerings, although at first glance the high-end Sonys Vaio seem expensive.

Lenovo has a trio of high-priced attractive machines offering a different mix of features and compromises. The list prices are mostly too steep, but there seem to be good prices sometimes on refurb jobs and I've had good experiences with those: both my laptop and my desktop are refurbs from Dell.

So I'm looking at the X200s, the X301, and the T400s.

The X200s is the lightest, in part due to the external optical drive. It's 2.47 lbs (!!!) with the 4-cell battery and a very attractive 3.0lbs even with the six cell I'd likely get. The problem is that there is no trackpad, and I've gotten pretty used to them. My experiences with that little red stick on the Lenovos hasn't been great — they seem hard use to make small adjustments as one often needs to do in documents.

The X301 might be perfect, at 3.3 lbs with a 6 cell and internal DVD, but it is expensive even refurbed, even with the smaller SSD drive — which I think will be enough for my needs. It seems to come mostly with various flavors of Vista, which is a bit of a problem as I'm still in XP land, and plan to stay there until I graduate to Ubuntu or am forced into Win7 or maybe Win8. I could get a regular drive, but I think I would very much benefit from the increased disk speed from solid state (and the modest weight savings) whatever model I get. My only worry there is that a future windows operating system, if I have to use one, might be so bloated as to fill the smaller SSDs….

The T400s refurbed isn't quite as expensive, although it's still up there, but the weight is getting up to 4lbs. I like its looks, although online X partisans sneer at its T-ness. But it weighs 4lbs, which is more than my current machine. Shouldn't progress mean things get lighter? (Although to be fair the T400s has a full 14” screen, and I'm used to the 12.x” variety.)

I'm thinking this isn't going to be easy. Or cheap.
