MacWorld ‘09

Tuesday, January 6th, 2009

Apple announced it’s new products for Q1, at least. iLife looks cool. Snooze on iWork. And the top end MacBook Pro that was left out of the Sept ‘08 upgrades was upgraded with a very cool custom battery that gives it 8 hr. Unfortunately, it didn’t get a Quad Core CPU. iTunes goes DRM free for more money. This really highlights the fact the DRM is a feature only for the copyright holder and is an obstacle for the consumer. Something artificial that you have to pay not to have. Wait, that sounds like protection racket.

I was hoping for Apple TV, Mac Mini, and Mac Pro updates. Particularly, the first two are looking very long in the tooth. The desktop Macs really have to wait for Intel to make lots of new quad core chips, which’ll be a couple of months. Also, iMacs were left out of the upgrades that the laptops received in Sept. The one where a slide was presented showing just how dog slow the iMac video cards are. I betcha this is all, because of the difficulty nVidia has had with shipping low defect chips. If so, Apple has got to be plenty pissed that many of it’s product lines are delayed, because of it.

Overall good, but boring. Show me the products that I know are going to be updated or tell me when. I don’t want an Apple TV that is obsolete 1 month later. Which is exactly what could happen in the next three months.

BTW, I’m loving the G4 Cube after the upgrade. It’s all back in it’s case, lying on its face, and running great. A few quirks like forget about using sleep mode, and the limited USB 1.1 bus can get drastically overloaded, forget running Leopard, and Adobe doesn’t know how to code Flash for G4s. It looks cool, runs pretty stable, and the CD through USB 1.1 scans and burns just fine. This has been my main computer for the past 3 months.

Semantic Philosophy Engine

Wednesday, December 24th, 2008

So, I’m catching up on philosophy lately. This is a very large field that it would take years of diligent study just to gain an overview.

I know it’s not reasonable to study the cliff notes. You need to read the author and get a feel. And there are other issues; language drift, translations from the works original language which of course has drift, unique usage of words that doesn’t match the dictionary definition, poor writing ability, and more issues I’m sure. Then there are non-philosophical texts, fiction, that depend upon a certain idea. A kind of submarine philosophical proponent. Some streams of thought overlap or dovetail yet the authors never knew of each other. Or their language is just different enough to make them seem unique.

I imagine these arguments are structured or partially so having a family tree. My interest is in generating a road map, reducing the number of authors to read, highlighting tourist traps, and actual scenic vistas. I’m reluctant to trust this job to a person. Each has biases and it would take a considerable amount of time.

My favorite tool is the computer and I think that what I describe is a semantic engine. Most of the work these days on semantics focuses on web search, but I think this is a dramatic waste.

Semantics is the meaning of words. It’s relative is syntax, which is the spelling and grammar of words. Computers don’t understand semantics very well. English is a shitty language in a lot of ways. One word has multiple meanings and the other words, which also have multiple meanings, must be used to figure out what is intended. In a way, we are all computers that have been left on for 10+ years. So, it’s not much surprise that a device with inherent weaknesses that’s a few minutes or even weeks old can’t keep up.

What I want is a box to which I can input text and it will compare the sentence structure and word usage, compare to other related texts, and generate a detailed comparison. I want the computer to read the text and tell me what else is like it. If an argument is a rabbit hole I don’t care for I want to it to warn me before I spend all that time reading it. The computer can do in minutes or hours what would take me days or months. This is all pattern analysis on a huge scale.

Eventually, I want it to do more. It should “understand”. I don’t know what this means exactly. Perhaps, generate cliff notes of any text with links to other texts that seem related. To place a text in relation to other texts that are similar. A big one is finding similar texts that are unrelated in time and place.

Eh, I’m getting sloppy in the specs. I think this could be useful to people in general, as a research age, plagarism detector, redundant text detector,.. I don’t know.

Our society has an increasingly unreadable quantity of text available. We could use a tool to help navigate this vast sea of information. Teaching computers to understand language and navigate the memes seems the only way to do this.

DOSBox

Sunday, October 19th, 2008

So, I was looking around for old games that would play well on the Mac Cube. Unfortunately, I didn’t have much luck and the Cube’s new 1.8 GHz (replacing .5 GHz) CPU is on the way. The Cube stands at a turning point in Apple history. It can play OS9 or Classic games and OS X games. It is 8 years old so anything that worked on it when new is long since abandoned now.

Some people still love the games for the Color Computer (1989), Tandy (early 1990’s), and DOS. Just look at the Atari game packs containing the greatest hits of the 1980’s. It’s funny how many more clock cycles our CPUs had compared to even 5 years ago. This computer has two complete CPU on the same space. With that much power you don’t need a Commodore 64 your can run it on any machine with an Emulator.

An Emulator is software that can make the code inside the Atari cartridge, floppy disk, or CD think it is running on the original, old system. This is horribly inefficient. There’s so much speed available you don’t even notice. In fact, most Emulators let you slow down, because the base computer is too faster and certain actions depended on the old timing.

In my quest for Mac games I discovered my old favorites. Games that ran in DOS the year I graduated high school and entered college. The Emulator to run them is DOSBox. It’s an open source project and it has the wonderful feature of running on Linux, Windows, and Mac. There is a text file that contains all the settings. It emulates a number of old Sound Blaster era sound cards and CGA and VGA era video cards. These devices were pretty low quality. The video especially is about what you would get from your standard TV.

Many games from this era have been abandoned or discontinued. If you are lucky you can find a download online. Some have been removed and others are available. Most of these games are 1-3 floppies or 1-6 meg. Most of us get more than that in email everyday.

My favorites are Colonization, the original, which has been remade very recently and is due out in a Mac version. And XCOM: UFO Defense. One more that I find tempting is Master of Magic and maybe Master of Orion. It’s hard to believe that these games are just as fun to play. The sound is marginally acceptable. The video is disastrously atrocious by today’s standards. The game play, the way the elements are balanced and the layout of the action screens, is much better the modern games.

Some other notables are Jagged Alliance and it’s sequel, Jagged Alliance: Deadly Games. Jagged Alliance 2 and it’s variations are worth playing too.

So, if you’re interested in getting back an old game check out DOSBox for the DOS games and look up how to play the Win95 and Win98 games in Vista and XP. If all else fails you can download VMWare Player for free, track down an image of a Win98 install disk, and create a gaming VM. That’s what I did.

Query by humming

Monday, September 29th, 2008

http://en.wikipedia.org/wiki/Query_by_humming

Query by humming (QbH) is a music retrieval system that branches off the original classification systems of title, artist, composer, and genre. It normally applies to songs or other music with a distinct single theme or melody. The system involves taking a user-hummed melody (input query) and comparing it to an existing database. The system then returns a ranked list of music closest to the input query.

Cnet: Revamped Google Picasa site identifies photo faces

Wednesday, September 3rd, 2008


Google wants to help you put a name to that face.

With a face recognition feature set to launch at noon PDT Tuesday, Google’s Picasa Web Albums will help users label their photos with the names of subjects. That and other changes to the photo-sharing site are joined by a new beta version of the accompanying Picasa 3.0 photo-editing software.

The “name tag” feature presents users with collections of photos with what it judges to be the same person, then lets them click a button to affix a name. Once photographic subjects are named, users can browse an album of that individual on the fly.

It took me less than 15 minutes to tag close to 200 faces in a set of more than 100 photos, and that included some start-up time such as figuring out how the system worked, establishing names for various common subjects, and correcting a few errors. The most impressive moments are when Picasa presents a large array of photos with the same face, and you can label them all with a single click.

Picasa editing software now lets users export movies with musical soundtrack to a file or YouTube.

I speak here from experience. I do tag my own photos–for example the 700 I took on a weeklong backpacking trip earlier this month–and something like Google’s facial recognition assisting would have dramatically sped the process. It wouldn’t help with other tags such as “swimming,” “waterfall,” or “Sierra tiger lily,” but let’s face it–people are the central feature in most people’s photos

Digital TV Transition

Thursday, June 12th, 2008

On February 17, 2009 all full-power broadcast television stations in the United States will stop broadcasting on analog airwaves and begin broadcasting only in digital. Digital broadcasting will allow stations to offer improved picture and sound quality and additional channels. Find out more about whether or not you will be impacted by the digital TV (DTV) transition.
http://www.dtv.gov/

Analog TVs Will Need Additional Equipment to Receive Over-the-air Television When the DTV Transition Ends
converter box imageConsumers who rely on antennas (including outside antennas and “rabbit ears”) to receive over-the-air broadcast signals on TV sets having only analog tuners will need to obtain separate digital-to-analog set-top converter boxes to watch over-the-air TV. These boxes receive digital signals and convert them into analog format for display on analog TVs. Analog sets connected to such converter boxes will display digital broadcasts, but not necessarily in the full, original digital quality.

Cable and Satellite TV
Cable subscribers may need new DTV equipment to view DTV programming in digital format. You should ask your cable provider what you will need and when.

Satellite subscribers may need new DTV equipment to receive and view high definition digital programming. You should ask your satellite company what you will need and when.

Analog TVs will continue to work with cable, satellite, VCRs, DVD players, camcorders, video games consoles and other devices for many years.

HiDef or HDTV, new LCD or Plasma TVs have nothing to do with digital TV.

The digital TV transition is for one purpose. To reclaim the UHF and VHF public airwaves for resale by the FCC to private telecommunications firms. Only broadcast TV carried over an antenna is affected. Cable is unaffected unless the cable company decides otherwise.

Working for Gratitude

Monday, June 9th, 2008

So, how does a gratitude based economic system work? Such a thing has been in development for some time. It’s in Open Source software. Most projects have taken to accepting donations. This model is not only applicable to software, but to services.

Jeff Atwood has a great post on making donations to the independent groups that make “free” software.

Some example of donation based services are the IT Conversations podcast site and the TWiT (This Week in Tech) podcast network. Both rely on small ads and donations. The TWiT site is a great example at making it easy to donate. On the left side are four links. Most of them are for recurring donations.

Cutting the Cable?

Thursday, June 5th, 2008

So, I had to call and have them turn on the cable tonight. Bills are details I don’t like to be bothered with. Usually, I blindly send money. The City of has been overpaid by 4 months or something.

It raised an issue. What if I removed the monthly cable bill altogether. What are my alternatives? Satellite, replaces one bill with another and they don’t always play well with TiVo. What about the Internet? A lot of attention is going to this lately. AppleTV, Joost, the Roku/Netflix box, Hulu, and whatever.

What do I watch
If I wanted to dump the cable company and go with Internet+DVD+AppleTV, what would I miss?
Battlestar Galactica – new
Dr Who – new to the US
Recent random stuff; Deadliest catch, 30 days, etc.
New HBO, this is getting drastically less
Law & Order, not as good this season
ER, boooring
Random old movies, The Man Who Shot Liberty Valance, Total Recall, etc.
Southpark – new

Local channels come through an antenna and can get picked up by TiVo. All four or five.

So, what’s available to rent purchase on iTunes?
Torchwood 1-2
Farscape 1-4+
StarGate 1-10
some HBO

Financials
Cable is $89.34/mo for Basic, Expanded, Digital Service (WTF?), CiniMax, HBO, the Box, and taxes. This would be 30 $3 movies or 22 $4 movies or ~3.5 TV seasons or 45 $2 TV episodes. Podcasts are free. Music is purchasable.

Ok, why is Suddenlink charging for Digital service when they want to switch everyone over to it for cheaper service call? And the FCC is about to mandate it next year so they can sell the UHF/VHF spectrum.

The hardware costs for AppleTV are “fixed”. $230 for 40 gig or $330 for 160 gig. Assuming that $45/mo in content is purchased the payback period is 5 and 7 mo, respectively.

Advantages
One nice feature is the integration of iTunes w/everything. The MacBook, AppleTV and RAID box can all play music and podcasts off one another. With an AirPort, this can be transmitted wirelessly w/o a computer on the other end. Some content is on iTunes that is not available on TV. That’s a surprise.

Content is not available by just turning on the TV. It’s on demand and my decisions affect cost directly. I no longer support entities I disagree with. Pick and choose TV.

Can be cheaper.

Disadvantages
Cable is really, drastically cheaper than this. TV shows should be $.50/episode and movies $1-2 for old and $3-4 for new. These are rentals and low quality at that. Rented content is expensive.

No DVD player in the AppleTV.

TiVo is far less useful. It can still download content of it’s own and I’m already locked in at a low price. So, I won’t turn it off

It’s hard to push RCA outputs over coax cable. These existing TVs in other rooms all use coax, because it’s more efficient to wire and runs longer w/o degradation.

Hours of delay in the purchase decision to viewability. Downloads are sloooow. I’m not willing to jump carriers unless NTS screws up or dies. AT&T and Suddenlink are fast, but really awful to deal with.

Overall
Local TV is about the same. TiVo will work with it. Need to look for digital antennas.

It’s a different idea. There will likely be some hiccups.

I can experiment with the Mac Mini. It does have a player and play most DVDs. iTunes is built in and all the remote controls are there. It’s just a little bigger.

Battlestar Galactica is my big hook. When they slow for a short time halfway through the season, I’ll look at cutting the cable. Most of the others, I weaned myself off of. No more Survivor, Amazing Race, Desperate Housewives, etc. And HBO keeps canceling all the good shows and throw up absolute crap for replacements. I’ve almost cut just HBO off. Idiots.

Maybe, this is something I want to do and maybe not. The 1st episode of Season 2 Torchwood is downloading right now. I should read more anyway.

Solar iPod

Friday, May 30th, 2008

The iPod Mini sucks the juice like crazy. It’s annoying in training, but will run dry on tour day. Not that it necessarily will get much use that day. Still, I would like the option. These are the links I found on making your own solar charger. It looks pretty simple.

Commercial chargers are $60+ and more likely $100. USB cables are 5V @500mA (2.5W). Some of these commercial ones only put out 5V @100mA (.5W). I’m not certain this would run the iPod for an extended period of time.

It should be simple enough to find a 5-6W small panel. The regular assumption is 50% of the max rated. Or 2.5-3W. Should be good enough for most small devices.

http://www.reuk.co.uk/Solar-iPod-Charger.htm

Update: 6/1/2008
Parts are ordered. Should be pretty easy to build. Had to ride w/o the iPod Monday, because it didn’t have a charge left.

External RAID Arrived

Thursday, April 24th, 2008

The external RAID box came in today. It’s formatting now. This would easily fit in a small shoebox and it’s very quiet. Formatting will take a while delaying any conclusions on performance or usability. With two GP WD 750 gig drives on idle it pulled ~18 Watts, which doesn’t seem bad for an always-on appliance.

One nice surprise was to see that it has iTunes integration. All of the music can be put on this one box and even if the MacBook is off or away on vacation another iTunes-aware box like the Mac Mini or Apple Airports could play off the RAID. It would be a great relief for the tiny hard drive of the Mac laptop to be lightened of it’s 13 gig load and well expanded to the potential 30 gig plus that is out there.

With the purchase of the RAID the network grew to house 4 gigabit NICs; the MacBook, work laptop, Mac Mini, and RAID. I also purchased a small 5 port Gigabit switch to serve as fast backbone between these devices. It’s not worthwhile yet to replace all of the 10/100 equipment yet with 10/100/1000, but this will offer quick transfer between the boxes that can run that fast.

ISPs Caught Editing in route Web Pages

Friday, April 18th, 2008

Why would ISPs be so willing to filter copyrighted materials when there is a huge exemption written in to law? This has puzzled me for years. I thought and still believe that there are payments from large content producers for just such an action. Another discovery by UoW and the actions of Comcast to filter BitTorrent traffic have also revealed what their intentions.

ISPs are planning to move away from simple connections and intend to edit the web streams that you receive. The University of Washington has reported ads being inserted into to web pages when some view a UoW web site. By injecting adds the ISP becomes a de facto web editor and throws away the legal protections in the DMCA. It’s crazy and very risky, but they’ll do it for the chance to make money in slow growth market.

In a paper, set to be delivered Wednesday, the researchers document some troubling practices. In July and August they tested data sent to about 50,000 computers and discovered that a small number of Internet service providers (ISPs) were injecting ads into Web pages on their networks. They also found that some Web browsing and ad-blocking software was actually making Web surfing more dangerous by introducing security vulnerabilities into pages.
ISPs Meddled With Their Customers’ Web Traffic, Study Finds

Being an ISP is a very static business, as it should be. It’s the equivalent of providing water, gas, roads, etc. Not sexy and with a very slow growth curve. So, how can they jack up growth and revenues for Wall Street. By selling everything and anything. ISPs believe they own you and your clickstream on both ends of the pipe. The monthly service fee is only the beginning. Ten years from now your Internet service fee should be double. Not because the companies have earned it, but because they seek to raise it to the maximum possible rate that the consumer will tolerate. After all, that’s supply and demand, right?

Match.com Photos

Wednesday, April 9th, 2008

I signed up for Match.com last night for 6 mo. It would be really nice to know why it creeps me out. Sooo, creeps me out. Maybe, it’s the pictures. I think maybe there is a rule that they be taken in bad lighting and/or with a camera phone. You can’t imagine how worthwhile it is to spend $20 at Sears for photos and scan them in.

My pic is the same as MySpace. It’s 3-4 yr old from Sears scanned in. A holdover from the Bridget epoch, but very nice. I really appreciate good photos. It’s like personal grooming for your online persona. You wouldn’t try to get a date with rumpled clothes, bad breathe, and crazy hair. Why post the photo equivalent to the internet?

CH: Setting up Subversion on Windows

Monday, April 7th, 2008

Setting up Subversion on Windows

Allow me to illustrate how straightforward it is to get a small Subversion server and client going on Windows. It’ll take all of 30 minutes, tops, I promise. And that’s assuming you read slowly.

Electric Motorcycle

Monday, April 7th, 2008

I started thinking the other day about electric propulsion. Since, I don’t want to blow $30k on car when mine works well what am I to do? Maybe they have an electric motorcycle? My requirements are pretty light. Something to take over the commute during the ~4-5 months of really nice weather we have. About 10 miles both ways at 60 mph. There’s a big ass hill to climb when going home, but you rid down that when coming to work. Charge at home.

The goal is to reduce the wear on the red car, reduce fuel consumption and costs by going electric, reduce overall costs, and in general be more energy-wise. I’m thinking $2k-$4k. Any more and it costs too much.

So, what do they have? No much, unless you have ~$10K. For that I can get a used car and continue with similar maintenance costs. Not worth it.

Seems like speed is the main issue. Most bikes are glorified mopeds or throwbacks to the 1920’s. They max out at 30 or 45 mph with a similarly short range. Very few will hit 60 mph.

Bikes
on Wikipedia
Vectrix $11K @ 60mph
EMB Lectra $4K @ 40mph
Enertia $12K @ 50mph
EVT America < 45mph
