Using Google to search quality

This post is a continuation to the previous post.

What bothers me is that CryptLoad wouldn't even appear on Google "rapidshare downloader" search first page. Live.com didn't have CryptLoad on the first page either, but it did have RDown. It's a bad Firefox add-on neither Google nor Yahoo found worth mentioning. Maybe better so? Live also was the only service which showed two linux-based applications on the first page. I thought it belonged to Microsoft...
CryptLoad did appear on the Yahoo first page along with bad results.

It's even worse for JDownloader. Yahoo had a link to JDownloader only on the 18th page! How can two of the best applications be so low?

I started to play with google search to find out, what searches can help find more relevant results. All I do is writing down the Google result count.

It's important for these Rapidshare downloaders, that they adapt to Rapidshare changes. If an application was good yesterday, it doesn't mean it's good today. So I chose Google option "past month". Now JDownloader has twice as many hits as the runner-up, and't it's good.
  Name (all time) (by month)
CryptLoad 834000 37200
JDownloader 405000 29900
Rapidshare Plus 320000 16400
Raptor 367000 14400
RapGet 346000 10100
letolto 167000 5140
RapidLeecher 62400 2900
RapiDown 46800 1180
Unlimited File Downloader 40300 994
Downloader.NET 28600 904
Rapget.RS 26200 171


Quality level
I found that COUNT_MONTH(rapidshare [application]) / (COUNT(rapidshare [application] doesn't work) + COUNT(rapidshare [application] error)) represents quality good. There's some sense in it - we want to count bad comments and at the same time make sure the development has not stalled. We need active changes but few mistakes.
letolto 2,887640449
JDownloader 1,811023622
CryptLoad 1,429669485
Unlimited File Downloader 1,39020979
Rapidshare Plus 1,237735849
Rapget.RS 0,501466276
RapidLeecher 0,464
RapGet 0,326649418
RapiDown 0,234872611
Raptor 0,161254199
Downloader.NET 0,03623537

I don't think letolto is accurate because a lot of complaints about it must be in gibberish, it's native language. All else seems right. Notice how "Unlimited File Downloader" is high. Spywares/Trojans/etc can have very good quality, so I also try to measure, how good the application is for users - praise level.


Praise level
It's not straightforward to filter out praising comments, I'll stick with the word "awesome". So praise level is COUNT(rapidshare [application] awesome) / COUNT(rapidshare [application] doesn't work)
Error is not included in praise level, because people can enlist errors yet like the application. In fact, for very bad applications, the reaction is less specific.
Rapidshare Plus  4,613953488
Downloader.NET 2,256756757
RapiDown 1,641242938
JDownloader 1,628272251
Raptor 1,608
CryptLoad 1,19941349
RapidLeecher 1,068965517
RapGet 0,817343173
letolto 0,621052632
Rapget.RS 0,316770186
Unlimited File Downloader 0,059815951

Here "Unlimited File Downloader" has plummeted down, noone praises it. Rapidshare Plus despite it's lacking quality really seemed praised a lot on the internet. I have no idea why RapiDown is so high or CryptLoad so low. I think I'm seriously lacking in my praise level estimation formula.


Final ranking
I can't come up with a good formula for this one. I'd just use quality ranking and ditch the lower part of praise ranks completely.
1. JDownloader
2. CryptLoad
3. Rapidshare Plus
4. RapidLeecher
5. RapGet
6. RapiDown
7. Raptor
I can't put letolto anywhere in this ranking due to it's internationality problems.

Best Rapidshare downloader

I was trying out various Rapidshare downloaders to find the best one.

Total and absolute failures

RapidShare Unlimited File Downloader 1.0.0.1
Rating 1.5 of 5 in download.com is way enough to label this crap and skip downloading. Well, what can you expect from a trojan...

RapGet v.1.41
Doesn't work and doesn't give a damn! How stupid is it to count errors, yet not tell what the errors are? Works with megaupload, sure, but not rapidshare. Shouldn't the name imply the opposite?

RapidShare Downloader.NET v2009 Preview
My love for unhandled exceptions is but an epic fail.

Raptor 1.1b
There is only one negative aspect to this app - it doesn't work! After downloading few-KB html files and renaming them as the expected result, Raptor feasts in belief of a work well done.

Rapidshare Plus
Is hanging up a feature now? When not hanging up, it simulates Raptor in it's entirety.

RapidLeecher 5.1
I've had nightmares better than this application... And, no, it doesn't work.

RapiDown
People tell it's a trial, spyware, and cannot be uninstallable. Do I want to install? Some other day.

Rapget.RS v0.9.7.1
Doesn't work. Has status "ready" for hours, never progressing. And, yes, I did press the "Download" button.

Working applications

RapidShare letolto 2.4
OMG, the interface, the horror... It really looks functionally good, but the interface is ass. First, the default language is gibberish (of course), so you have to be a real magician to find out where to change it to english. Too bad whenever you really need english, the text is left untranslated!

CryptLoad v1.1.5
Nevermind the fact that it takes forever to load and eats 70MB of RAM when idle, this one actually works. It's simple enough, and I couldn't find major faults. It dislikes spaces in file names. But it's auto-updating, so whenever RapidShare changes, this program will make sure to update itself (much unlike other crap). The link collecting feature is also nice. On the bad side - why doesn't it allow leaving files in list after downloading? I mean - this app is still crap, but it works.

JDownloader 0.3668
It took me ages to find this app's homepage! You thought writing "rapidshare jdownloader" in Google should show the homepage as the first result? Nope. And after I went through the trouble(!) of downloading the latest version, I find out that... it's quite good. It has auto-updating, link collecting, nice interface and doesn't remove files from list after downloading. Man I must be testing too much crap, if I call this one good...

P.S. It appeared to me that all(?) of the apps used the URL to identify the service. Whenever a link changing service is used (such as linkto.net), these applications fail miserably!


Summary: If your computer is not aging, get JDownloader (my favorite) or CryptLoad. Otherwise, you can try "RapidShare letolto". Everything else is even worse!

Washing machine brand reliability

I wanted to buy a washing machine that has only two things:
1) Works
2) Cheap

It's actually not easy, because cheap washing machines fail a lot. And so do expensive ones! There's no use for features when the device doesn't work...

I believe that generally companies either produce qualitative product or crap. It's all about brand names and factories. So I googled to find which washing machine brands are the most reliable. Example queries:
"worst washing machines"
"washing machine worst brands"
etc.

Whenever some site had a strong opinion about a brand, I put a plus or a minus for the brand. Whenever it had strong opinions about multiple models of the same brand name, same thing.

The "who owns who" game... Quality reviews for a 3 year old washing machines don't neccessarily represent current quality. I didn't keep track of dates (though ignored the "have it for >5 years" reviews), so I'll pretend all reviews are for recent models.

Current situation:
Electrolux brand names: AEG, Electrolux, Frigidaire, Kenmore, Tricity Bendix, Zanussi
Whirlpool brand names: Kenmore, Maytag, Whirlpool
Candy brand names: Candy, Hoover
Indesit brand names: Ariston, Hotpoint, Indesit
GE brand names: GE, Hotpoint, RCA

Miele is the most reliable, noone seems to even doubt it. Bosch-Siemens group follows. Hoover is the worst brand. Lack of positive reviews for Samsung surprises me. All else is visible in the list above. And, no, there is no conclusion.
