Mother Jones has collected some interesting housing statistics.
- 1 in 4 Americans want at least a 3-car garage.
- Extreme Makeover: Home Edition recently gave a 6-bedroom, 7-bath, 7-television house to a family of 4.
- 1 in 5 new homes is larger than 3,000 sq. ft. the size at which it becomes unmanageable to clean without hired help.
- Only 2.7% of San Francisco?s teachers, 5.7% of its cops, and 4.2% of its nurses can afford to buy a home there.
I read Eats, Shoots & Leaves last weekend. I suspect that it's one of the few books on the reference/humour shelf at the bookstore. It's a book about punctuation. Remarkably, it was a best seller in Britain and has received a number of good reviews. The author, Lynne Truss, rants about poor use of punctuation by shopkeepers (and, based on the number of times she complains about greengrocers, she must live in the vegetable capital of the UK), gives some history about how various punctuation marks came into being, and gives some tips on how to use them correctly.
I found some comfort in learning that nobody agrees on the proper use of commas, and, so, I will use them aggressively, as I see fit. I will also try to incorporate more colons and semicolons into my writing; a key that was, up until now, largely reserved for writing code will be set free. I was also happy to learn that British authors, like any programmer, know that it's proper for trailing punctuation to appear without quotation marks.
One bit of punctuation that I would like to bring back is two spaces after a period (full stop). I learned it in typing class in high school, and didn't realize that it doesn't exist in books until Ms. Truss pointed it out.
It's amazing the number of times I've received email saying something like, "Here's the first eight digits of my credit card number. I'll send the second eight in another email (for security)."
This is not security. I wonder how people come up with these ideas. Do they think criminals accidentally intercept random emails sometimes? Or that they are able to intercept some messages, but there's no way they would be able to get two in a row?
I got my free iPod
Shuffle yesterday. I spent way too many hours trying to get it working.
On my laptop, with a 2.6.9 kernel, hotplug loaded the ub
module instead of usb-storage. I upgraded makedev and created
/dev/ub* devices, but I couldn't access the /dev/uba device.
Finally, I tried it on my desktop with a 2.6.10 kernel, and after plugging it
in a second time, I was able to access the Shuffle's vfat filesystem as a scsi
I installed gtkpod, and was able to create the appropriate directory structure and copy over some mp3's to the Shuffle. I plugged in the headphones, turned it on, and it played. It sounds decent with the headphones Apple supplies, but better with my Sony ones. Apple really should have integrated the headphones into the lanyard it comes with. Or there should be a spring-loaded device to coil up the wires.
One thing my Shuffle doesn't do is shuffle. It works in normal, linear mode, but in shuffle mode, it won't play anything. Perhaps gnupod didn't create the directory structure correctly or something. I'm an album listener rather than a single listener so it's not a big deal, but I don't like knowing that my new gizmo isn't functioning properly. One other problem is that when it's plugged into my usb port, the light always blinks orange. It's supposed to be green when fully charged, but I left it plugged in all night, and it greeted me with flashing orange in the morning.
One caller was a real estate agent who claims there's not enough land in Las Vegas and that it will become a land of high-rise living. Another said that Cleveland was becoming too expensive. As an aside, I spent a couple hours in Cleveland in 2000, and left with a favorable impression. Downtown seemed to be undergoing a lot of development.
From the book:
Irrational exuberance is the psychological basis of a speculative bubble. I define a speculative bubble as a situation in which news of price increases spurs investor enthusiasm, which spreads by psychological contagion from person to person, in the process amplifying stories that might justify the price increases and bringing in a larger and larger class of investors, who, despite doubts about the real value of an investment, are drawn to it partly through envy of others' successes and partly through a gambler's excitement.
I was recently faced with what turned out to be an unexpectedly difficult task. I had to copy about 700GB of data from one filesystem to another. The data was comprised of the backups of about 40 servers as stored by BackupPC. BackupPC is a great piece of software for backing up a network of servers. It can backup machines using SMB, rsync, and tar over rsh/ssh. It compresses the backed up files and pools them so multiple copies of the same files are stored as hardlinks to the compressed files in the pool.
In order to increase the storage capacity of the backup server, I was tasked with adding a second RAID array. I set up an LVM volume on the new array, and then needed to copy all of the files from the old array to the new one.
First, I started up rsync and let it go. For a long time, the rsync process just kept growing and growing. Before it starts copying any files, it goes through all of the files to figure out what it's going to copy. A known limitation of rsync is that it uses a lot of memory when there are a lot of files involved. I didn't know how many files we had, but with 4GB of RAM in the machine, I was pretty confident that we would be ok. After more than 24 hours, before it had started actually copying any files, rsync died as it hit the 3GB per-process memory limit.
For my next attempt, I used
cp -a. cp started out alright.
Throughput from source volume was pretty abysmal, but after about 5 days, the
entire pool of compressed files had been copied. As it was copying the
individual servers' backup directories (which contain the hardlinks to the
cp also hit the 3GB limit and died.
I briefly thought about using sgp_dd to do a lower level copy of the data, but we really wanted to use XFS for the new filesystem; the original filesystem was EXT3. I didn't confirm whether it would work with LVM volumes either.
I ended up just starting with an empty BackupPC directory. We'll keep the old backups for a while until we have sufficient history. Then, we'll add the old array to the new volume for additional disk space.
An interesting project might be to add an optional argument to rsync to allow it to use a dbm file to maintain state rather than keeping everything in memory. I guess nobody anticipated terabyte-sized disk volumes being used with 32-bit processors.
Over on TJ's Weblog, they picked a company planning on opening a spa in Slovakia as one of their top 3 business plans.
TOP 3 - comes in MAGMA ZAFÍR s.r.o. that aims to develop a hot water spa in Slovakia. Central Europe has been less then well served with wellness facilities so far and has the advantage of cheap labor costs. A world-class spa for clients from Germany and Austria could easily fill a market void.
I'd be interested in reading their business plan. Slovakia already has a number of spas, and Piestany has attracted foreigners from around the world to its spas for a long time, even during Communism.
Slovaks, in general, see spas as places for the elderly and infirm, but that may start to change. When I was in Slovakia a few weeks ago, there was an article in a magazine describing a visit to a spa by a young woman. She hadn't been too thrilled about her assignment to visit and write about her experiences at a spa. She figured she had twenty or thirty years before she should start visiting spas. She was delightfully surprised by her experience and concluded that visiting spas was a great way for young professionals to relax.
I think there could be a good opportunity in marketing spas to Slovaks between 20 and 40.
I filed my taxes Tuesday night. It wasn't quite the relief it usually is though. This was the first year in which my income was mostly 1099 income. That means that self-employment tax reared its big ugly head. I knew it was coming, but when it looks you in the eyes, it's still frightening. After writing off my business expenses, my total taxes were actually about $3,000 less than the rough estimate I made last year when filling out my 1040-ES. Nonetheless, I still owed the feds over $10,000 of the almost $19,000 total tax liability.
What makes the number so shocking is when you compare it to a return for which all of the income is W-2. With W-2 income, the section of the 1040 labeled Other Taxes is generally blank. As an employee, you pay 7.65% of your wages for Social Security and Medicare insurance, but this amount doesn't show up on your tax return. When your self-employed, the 15.3% tax on your net business profit shows up under Other Taxes, increasing the bottom line (line 62, that is) substantially.
One nice thing about being self-employed is being able to write off business expenses that employees typically can't. This year, I expensed gas and other automotive expenses, internet access, office supplies, part of my rent and utilities, and depreciated computer equipment and part of my car. Working from home, I don't have too many expenses so I was only able to reduce my gross income by about 6% in calculating my net profit. I was also able to write off my health insurance premiums, but that only reduces my adjusted gross income rather than business income, and thus doesn't reduce the SE tax. So I was left with a large amount of self-employment tax to pay.
In 2005, I'm going to set up and contribute to a SEP-IRA and a Health Saving Account which will reduce my income tax, but not my SE tax unfortunately. To reduce my SE tax, I may form an S Corporation. Paying myself half the corporate income in salary, which is subject to SE tax, and rest as a distribution, which is not, would probably be fair and would reduce my SE tax by quite a bit.
Cantillon's Paradise points to an AP story which says that Americans spend 6.6 billion hours on their taxes. It's rather ridiculous the lengths a citizen must go to in order to comply with the law. Luckily, our civil servants are working to resolve this issue.
Sensitive to the demands that tax laws put on weary taxpayers, the IRS has seven people working full time to reduce the anguish for filers. The IRS Office of Taxpayer Burden Reduction looks for requirements that can be streamlined, reduced or eliminated under the law.
Of course, there's only so much they can do considering the amount of tax law that are in charge of enforcing. Congress is responsible for the mess.
I've probably spent at least 60 hours on taxes so far this year, mostly reading IRS publications, including best sellers Business Expenses, Business Use of Your Home, and the much referenced tome, How to Depreciate Property.
My wife recently decided to change her major to accounting. I think I have the perfect internship for her.
The two books by Seth Godin that I've read, Purple Cow and The Big Red Fez, were both good. So, when Seth announced The Big Moo on his blog, I was excited about getting my hands on it. The Big Moo is a collaboration between Seth and 32 other business writers, with each writing contributing a chapter on how to make your business remarkable. As an interesting marketing idea, galleys (pre-release) versions of the book were offered in boxes of 50 for $2 each ($100 per box). Their goal was to get word of the book out early so big companies would buy truckloads of the book for their executives.
Back in 2000, the president of BNW bought everyone a copy of Tom Peters's The Professional Service Firm 50. The Big Moo is a similar type of book, but without the annoying typography (lots of different font sizes, bold, exclamation points, etc. I hate the style of writing in Peters's book. If you need to trick me into getting excited about your writing, you haven't written a very good book. Get me thinking, and I'll be excited.) It's not that it's a bad book, but it definitely under-delivers. Each of the authors contributed a single chapter, and most "chapters" are two or three pages long. It feels like you're reading a brain fart that the author couldn't bother to think through fully.
It's definitely not the type of book that forever changes your thinking: it wouldn't be included in a personal MBA list. So I'm not sure what I should do with 48 unread copies of the book (I did give one copy away). I can't give it to people saying, "You have to read this!" And I don't really want to give it someone and say, "Here's an OK book you might want to read if you don't have anything better to do."
The book does what it sets out to do: motivate the reader to get out there to put ideas to work to develop a remarkable organization that gets everyone buzzing.
As does Jack at 800-CEO-READ. Though he seems to like the book mostly because the proceeds go to charity. That's not a very good reason to read a book. You'd be better off giving the money directly to charity and avoiding the printing costs.
Update (10/10/05): I managed to unload two copies. Thanks, Heather!
Update (10/18/05): John, who also took a copy off my hands wrote up a review on his blog.
I recently upgraded a Pogo Linux StorageWare server. The server came with a 3ware 8506-8 SATA controller and 7 250 GB drives which we have configured in a RAID 10 array with one spare (the OS is on a separate 80GB drive). The server has 16 drive bays in total, so we decided to buy a second controller and 7 more drives to be configured in another RAID 10 array with one spare.
I had a couple problems getting the new card working. First, I had to upgrade the kernel to get the 3w-9xxx module. The Debian package for 2.6.10 worked. The next problem was using the 3ware management utilities. 3ware provides two utilies, a command-line one called tw-cli, and a web-based interface called 3dm2. According to their web site, the "in Engineering Phase" software should be used with a 2.6 kernel. When I tried using the software though, both tw_cli and 3dm2 reported "Application too old for controller firmware". I contacted the always helpful Pogo support folks who advised me to use version 184.108.40.206 of the 3ware software, which is a released version. The 220.127.116.11 software was able to detect the 9500, but not the 8506, so I tried version 9.2 which was able to access both. So it seems that "in Engineering Phase" means outdated as it's older than the released version.
Having gotten the 3ware software working, I was able to create and delete
arrays from within Linux rather than having to use the BIOS utility. Then I
could benchmark various RAID configurations. I tested RAID 10, RAID 50, and
RAID 5 with 6 drives and with 7 drives. (RAID 10 is striping across
mirrored sets of disks and RAID 50 is striping across RAID 5 arrays) In
any configuration, the 9500 blows the 8506 out of the water. I ran my
benchmarks using bonnie++.
With RAID 10, I was able to get about 170 MB/s write speeds and 185 MB/s reads.
Setting a large read-ahead value of 16384 (
blockdev --setra 16384
/dev/sdc1) significantly improves read performance so I will have to
tune it for the best performance once we put the new drives into production.
Striping across 2 3ware RAID 5 or 3 RAID 1 arrays
using LVM gave almost as
good performance as RAID 50 and RAID 10 3ware arrays, respectively.
With RAID 5, using 7 drives in the array rather than 6 gives better read performance, but poorer write performance. The additional drive also seems to adversely impact file creation and deletion speeds.
XFS seems to give the best overall performance. Ext3 gives good read performance, but mediocre write speeds. Reiserfs is very fast at creating and deleting files, but doesn't give as good throughput.
(Via Housing Bubble) LA Times has a story about the increasing popularity of interest-only mortgages. An astonishing 47.8% of homes sold last year in California were purchased with interest-only, adjustable rate mortgages. In 2001, it was 1.4%, and I'd bet that almost all of those were purchased by investors who wouldn't be holding the property very long.
Many of these people are buying with no money down so when interest rates rise and they can no longer afford their mortgage payments, there's no disincentive to simply walk away from the property. You don't need to have very good credit to buy a house these days; what's a little bankruptcy blemish on one's credit report.
"I have $40,000 in student loans from my master's degree," Herron said. "I have high credit card debt. I'm a typical American. And yet they wanted to give me more debt to buy a house."
She wonders sometimes if she'll end up in foreclosure, if the bank will take her beloved home away from her when she can no longer pay her bills. Maybe it was a mistake to give her this money, maybe it was a mistake for her to take it. But she wasn't about to protest.
"If you're like me, you're so incredulous that anyone would give you any money whatsoever, you just close your eyes and sign the papers," Herron said. "I would have signed anything."
The state is that great fiction by which everyone tries to live at the expense of everyone else. - Frederic Bastiat
