Linux BitTorrent Clients – Follow-Up

I’ve been using several Linux bit torrent clients fairly heavily for the past week or so, and I have a few new comments about each of the “contenders” — below I’ve ordered them as I would recommend using them.

KTorrent · KTorrent might be a little “fat”, but it works, and it works very well — particularly when dealing with a large number of torrents simultaneously.  This is my pick.

TorrentFlux · TorrentFlux is probably the best solution you’ll find for a torrent server.  Simply said, it works fine (though I don’t know that I’ll continue to use it, simply because it doesn’t seem to be being improved, and it’s far from perfection).

Transmission · Transmission is simple, and that simplicity seems to pay off — it works, it works well.

qBittorrent · qBittorrent works fairly well for a small number of simultaneous torrents; but if you want to download large numbers of torrents or seed large numbers of torrents stay away from this one — it actually crashes, and unless your goal is just to watch the integrity of your torrents be checked and over and over you can do much better.

Deluge · Deluge was what I really wanted to like; and it seemed to work, but it has two major problems — it doesn’t handle large numbers of torrents well, and it doesn’t properly handle port forwarding (either through UPnP / NAT-PMP or when you try and set the port forwarding manually).  We’ll just leave it at it has issues (that apparently are fairly well known) and the progress on it is glacial in it’s pace.

Moving torrents from one client to another isn’t all that hard to do, a little time consuming maybe… but once you figure out how to do it, and let your data files re-check, you’ll be on your way.

My experience over the past week reminds me that you can do your diligence by researching every fact and figure about a program all you like; but until you put it through the paces you just won’t know.

NOTES: My test included about 550 torrents totaling just under half a terabyte in total size.  I required that ports be forwarded through a firewall properly (either via UPnP, NAT-PMP, or by hand), and that I be able to control the total number of active torrents (preferably with control over uploads and downloads as well), and be able to restrict the bandwidth (a scheduler was a nice touch, but not a requirement).

A season of peace on Earth…

and good will toward men.

Hardly.

It would truly be the most wonderful time of the year if there were peace; even if the peace were momentary, but especially if it were lasting.

Christmas in the US is a commercial holiday, filled with greed and consumerism.

The religious zealots who co-opted a pagan holiday have a longer history of violence than peace — so when they try and tell you what the true meaning of Christmas is… ask yourself how many people who don’t share their views must die so that they can have their reich.

The emporer has no cloths.

In the US we don’t only have freedom to choose our religion; we have the freedom to choose to be free of religion and all the oppression that history shows it brings with it.  Make your choice known.

Macs Don’t Have The Problems PCs Do!

And I have a bridge for sale…

I’m sure you’ve heard your friend the Mac bigot tell you this and that about the Mac is better.

You know, the file system doesn’t fragment, it doesn’t crash, it’s easy to use, software uninstalls properly…

I’ve talked about fragmentation before; and there’s no reason to cover that ground again.  As to it doesn’t crash, well… you don’t see the sad Mac or the bomb any more — but it crashes, sometimes you get a kernel panic, sometimes it just reboots (I’ve seen both)…

But the really amusing thing is the software uninstall myth.

That’s a load of CRAP.  The real problem is most Mac user’s wouldn’t know if software uninstalled or not — as long as the entry disappears from the Applications folder they think it’s been uninstalled.

Open up a “Terminal” window and ‘sudo bash’ — then have a look around at all the garbage that gets left by uninstalls and upgrades (including Apple software).

Two that are great are VMware Fusion, and Parallels Desktop — but almost every piece of software I’ve uninstalled or upgraded seems to leave something behind.

Installing and un-installing software really isn’t as easy as it seems it should be; but a lot of the problems with the install and un-install are the operating systems really weren’t well engineered for that in the first place.

Both Microsoft and Apple attempted to come up with standards for software installation; and for the most part I think vendors follow those standards… at least where the standards are clear.  But it’s just more complicated than it really needs to be, and the software developers are expected to track too many things.  Like I said, Apple can’t seem to do it on OS-X, and Microsoft can’t seem to do it on Windows — so what chance has the mortal software developer got?

Computer Tid Bits; Malware

Computer viruses, worms, trojans, etc are on the rise… if your computer is connected directly to the internet (or on a public wireless network) you’ll definitely want to have a firewall enabled.  The firewall in Windows XP SP2 (or better) and Vista is reasonably good (so there’s no reason to spend money on one).

Also, you should definitely consider running Windows Defender (free from Microsoft) and a Virus scanner.

Two good free Virus scanners are Avast and AVG.

Avast is extremely thorough, but can put a bit of a load on lower end systems.  AVG isn’t as thorough, but a great deal lighter on CPU.  Also, Avast will require you to register for a key — you can use a throw-away email address (from my experience they don’t seem to SPAM).

Deep Throat

I watched a documentary called Inside Deep Throat — and I found it far more interesting than I think I ever found the movie.

The documentary talks about the changes occurring on the sexual landscape of America… while the sixties might have been referred to as the sexual revolution, it was really the early seventies where the battle of sexual expression was waged.

The movie was a landmark in many respects — but it’s success really had little to do with the quality of the movie, but rather the legal battles it caused — even though a presidential (appointed by Richard M Nixon) commission had already recommended that laws controlling pornography be repealed since they were largely unenforceable and that pornography caused no real risk to adults.

Watergate was only one of Nixon’s lies.

Sure the movie broke a great deal of new ground in film in general and porno specifically… but what it really broke was political and social stigma.

The trial in New York City (Judge Tyler ruled the file “obscene”) and an article in The New York Times catapulted the movie to the most profitable movie ever — $600 million US for a movie that originally cost only $25,000 to make.

The movie was eventually outlawed in 23 states; and the FBI harassed the director, producer, financiers, and theater owners.

Nixon’s four appointed Supreme Court Justices gave censorship a leg up; initially the feminist movement and the “protect our children” radicals supported the ban on expressive file; but steadily community standards changed possibly because of the VCR (and later DVD) and individuals began to demand their freedom of expression.

In most part of the country today individuals are free to choose; but believe me, there are still backward places that attempt to legislate morality — oppression controlled by the radical Christian right.


Below is a summary of court cases revolving around obscenity.

1957 Roth v. US – the Supreme Court defined obscene material is that which lacks any “redeeming social importance.”  The Supreme court combined the cases wof Roth v. US and Alberts v. California.

1964 Jacobellis v. Ohio – the Supreme Court reverses a state obscenity ruling, but issues four separate opinions laying the ground work for confusions.

1966 Memoirs v. Massachusetts – the Supreme Court attempts to better define the ruling in Roth v. US.  A work had to be proved by censors to: 1) appeal to prurient interest, 2) be patently offensive, and 3) have no redeeming social value.

1973 Miller v. California – the Supreme Court reinforces that obscenity was not protect by the First Amendment and established the Miller test but acknowledged “the inherent dangers of undertaking to regulate any form of expression,” and said that “State statutes designed to regulate obscene materials must be carefully limited.” 1) whether the average person, applying contemporary community standards (not national standards, as some prior tests required), would find that the work, taken as a whole, appeals to the prurient interest; 2) whether the work depicts or describes, in a patently offensive way, sexual conduct or excretory functions specifically defined by applicable state law; and 3) “whether the work, taken as a whole, lacks serious literary, artistic, political, or scientific value.”

1973 Paris Adult Theatre I v. Slaton – the Supreme Court upheld a state court’s injunction against the showing of obscene films in a movie theatre restricted to consenting adults; however, the Court differentiated the case from 1969 Stanley v. Georgia.

1990 FW/PBS v. City of Dallas – the Supreme Court ruled the city ordinance attempting to regulate “expressive businesses” as unconstitutional.

1999 Free Speech Coalition v. Reno – the Ninth Circuit Court of Appeals ruled against section 2556(8) of the Child Pornography Prevention Act (CPPA)  stating 1) the statue is not content-neutral and aims to curb specific expression; 2) the statute was not in line with Supreme Court decisions which have held that states can only criminalize child pornography when the laws “limit the offense to works that visually depict explicit sexual conduct by children below a specified age” – something the CPPA failed to do; 3) no demonstrated link to harm to real children has been demonstrated; and 4) the language is too vague and over-broad, allowing for arbitrary and discriminatory enforcement.

Panasonic HDC-SD10 High Definition Camcorder

I purchased a Panasonic HDC-SD10K High Definition Camcorder from B&H Photo Video a little over a week ago for $299.00 delivered.  The K suffix means black; which is I believe the only color available in the US.

I had originally found this model camcorder on Amazon for the same price as a customer return, but I was a little hesitant to purchase it, and by the time I decided it was worth the asking price it was no longer available; but as luck would have it a few days later B&H was offering brand new units for the same price.  The B&H price is good through 16 January 2010 while supplies last.

First, let’s keep in mind that $299 is less than half as much as the nearest comparable camcorder; so if it doesn’t seem like this is a Rolls Royce, perhaps that’s because you’re paying Yugo prices.

The HDC-SD10 was announced last year at CES, but didn’t ship in the US until this past Summer, and it was never really a very popular model since Panasonic offered an almost identical model with 8GB of internal memory (the HDC-SD10 has no internal memory) for $50 more.  Other than the internal memory, these models are identical.

A quick overview of the HDC-SD10 (for those who don’t want to just look up the specifications for themselves).

1920x1080i MPEG4-AVC/H.264 video, 2.1MP JPEG stills, 1/6″ CMOS, 16x optical zoom, 2.7″ touchscreen LCD, image stabilization, auto focus, built in light and flash.

When the unit arrived, I opened the box and allowed the battery to charge for a couple hours before trying it out.

While the batter was charging I looked over the unit.  It seemed reasonably well constructed, and it looked like a good deal of though had been put into positioning the controls.  The only thing I don’t care for is how the cover on the SD slot opens — I’m very partial to how Nikon did the SD cover on my D40, and this just seems far less well done.

I popped a 2GB SD card into the camcorder (I expected it to complain about the slow speed rating, Panasonic recommend Class 6 SDHC cards); but to my surprise it worked.  I would recommend that you use at least Class 4, and that you use at least a 4GB SDHC card.  But if you have other cards around, try them.

Unfortunately, by the time the battery had charged, the sky was cloudy and I was robbed of my opportunity to get some bright daylight shots — but I figured taking shots in overcast would give me an idea of how the camcorder worked.

I took two videos outside at the second highest quality setting (that’s the default); and I snapped about a dozen still images.  Then I went inside and did pretty much the same test.

The two video tests were:

  • walk back and forth with the camera
  • stand stationary and rotate around

Both tests involved using the zoom in and out (both moving and stationary).

I should note here that I did all of my initial testing without reading the documentation — this should be considered a testament to how easy this camcorder is to use for anyone who’s used a camcorder (or digital camera) before.  The controls were easy to find and use and there was simply no confusion about how to accomplish my task (which is good; my old JVC camcorder always seemed awkward to use, even after having it for several years).

With my test data collected I sat down and the computer.

I didn’t bother installing any software on my computer, I just popped out the SDHC and slipped it into the computer.

The digital stills were easy to find; same directory structure as most digital cameras.  The images are JPEG files, and contains EXIF data.

The video sequences took a little more looking to find, and they are standard AVCHD (MTS) files.  Both Windows Media Player and Live Movie Maker are able to deal with these files.

Let me pause here and remind you that what follows is my first impressions of the HDC-SD10; not a complete review.  My personal feeling is you need to use a camera or camcorder for several shoots before you’ve got a good feel for what it does and how well it does it.

The outside stills were good.  Certainly they don’t compare with either of my DSLRs or my high-end point-and-shoot… but then again, this is a camcorder, not a camera.  The only weakness I found with the digital still was that focus cycle requires a few seconds and the shutter release is not locked out during the focus cycle.  Which means you can snap a picture that is out of focus fairly easily if you’re not patient.  You can snap a still image when the camcorder is recording or when it isn’t.

The outside video was amazingly clear.  The color was very good, and the motion was acceptable.  Quickly panning produced some motion artifacts, but normal movement was far clearer than on my JVC miniDV camcorder.  I will have to say that my feeling is that the zoom is too fast; but I guess it’s better to be too fast than too slow; and for most people I would expect they want a fast zoom.

The inside still images were fine.  The flash works very well.  The colors were about what you expect from a mid-range point-and-shoot.  Nothing to write home about, but acceptable if you need to snap a still and you have the camcorder in your hands.

The inside video was actually quite impressive.  The reviews I had read of the camcorder indicated that low light performance wasn’t very good.  From what I saw low light performance was quite good.  In rooms with no lights on the camcorder was able to register a moderate amount of detail just using its built in light.  In reasonably well lite rooms the level of detail was quite good.  However, the color under LED lights or CF lights was definitely off (I don’t have any incandescent lights in my house, I suspect the color balance would have been better).  Comparing the performance of this camcorder to my JVC miniDV it is definitely better.  Better detail in low light, and equal or better color.  Obviously if I wanted to shoot any video that I was going to show someone I’d turn on some incandescent lights (bounced off the ceiling).

The sound quality on the recordings were fine.  There was quite a bit of wind outside, but the camcorder didn’t seem to be able to deal with it.  Obviously the stereo separation on any camcorder without external microphones is poor — and not a metric I’d concern myself with.

At this price point, the HDC-SD10 seems like a keeper.  You’d pay as much for a standard definition digital camcorder, and half this much for a standard definition miniDV camcorder; or twice as much for a camcorder with substantially better specifications.

I’m hoping the weather here warms up some so I can get out on a sunny day and really shoot some footage to fully evaluate how the camcorder works; and I’d like to do some shoots on the river and at the beach as well.  My expectation is that this camcorder will be fine for me, and I’ll be looking to purchase a few accessories in the near future.

If you want a really high end camcorder; this isn’t for you.  If you want a good quality high definition digital camcorder for hobby use and your not foolish about throwing your money away, perhaps it is worth consideration.

Windows 7 Sins

Personally I think this is a little over the top — the choice of an operating system doesn’t necessarily lock an individual into all the technologies that might be offered with it (for instance, you can run Open Office on Windows 7 — you do not have to run Microsoft Office 2010); but that said, this is a valid position and while it might be overstated it is something each and every person should consider.

$35 Tablet PC

The government of India has unveiled a $35 tablet PC that they intend to use to replace text books in India.

The Laptop Per Child project (OLPC) developed a $200 durable notebook prototype in 2005 that’s designed use in schools in developing country and has plans for a $100 tablet.

India, though, has created a computing device that costs less than most text books, and the government will further subsidize the cost.

In a country where electricity is a scarce commodity in many regions (the tablets will have a solar power option for use in rural areas) they seem to have a much better grasp on the concept of leaving no child behind and creating a technologically empowered generation ready to perform the jobs of tomorrow.

The US leaves no child behind by simply holding everyone back to the level of the underachiever — easy to understand why we’re becoming a third world nation.
