My Netgear EVA2000 went into strange mode 1 day after being hooked to Internet

Update:  I was finally successful in replacing my old disabled by the corporation media box... Raspberry Pi using the Raspbmc distribution:  http://mystry-geek.blogspot.com/2013/05/finally-got-raspberry-pi-to-try-out.html


Let me know if you owned a netgear product that might have also been deactivated in this way.

So, I finally hooked my Netgear EVA2000 multimedia internet device up to the internet after having owned it for a couple of years and the day after I hooked it up, it crapped itself.  Evidently they phone home when they are connected to the Internet, and it got some sort of message from home to crap itself.

 I searched on the Internet and a lot of people have had this same problem with no  resolution from Netgear.  So I decided to give Netgear support a shot.  Wish me luck.

I have had [ my netgear eva2000 ] hooked to my tv for about 2 years now and it has worked flawlessly to play movies off a hard drive and to play movies from a media server through the internet without any issues.

I finally got an internet connection and hooked the device to the internet so I could get access to the other functions. The day after it had access to the internet it updated the firmware without asking me and all the functions on the device no longer works. The main menu comes up as: My Collection Movies on Demand Internet video Settings And only settings works, clicking on the others just moves the cursor down to settings. There used to be a youtube option and it is now gone. Settings works fine, but having a little box hooked to my TV that _only_ allows me to change its settings is sort of useless.

A soft reset and a hard reset does nothing to resolve the issue.  [evidently they call it a soft restore and a full restore]

The only way I can get to my local media server now is to goto Settings->Eject USB disk, wait a few seconds, plug the drive back in, wait a minute or two, hit OK to browse the disk when that finally comes up. This window goes away quickly, so I am forced to stand there like an idiot for a couple of minutes waiting for this screen, or I have to start the process all over again. I am finally sitting at the screen where I can select my hard drive, if I press back at this point I can get access to the menu that my collections should take me to.

To sum it all up, it appears that connecting to the internet allowed my box to phone home looking for an update and it was ordered into this mode by your company. Needless to say, I am upset that you deliberately broke a perfectly functional unit, with what I can only assume is a desire to sell me a newer product. If you cannot fix my eva2000 back to a working state, or provide me with a working replacement unit, I will never purchase any product from your company again. I will instruct all my friends and family to not buy your products. On every internet forum that discusses your products I will tell my story about how it appears that you deliberately crippled my device at end of life in order to force me to purchase a newer product. Good day.

I replied that I tried the above and it did not fix my problem, asked about a firmware update, and was given this response:

Your request has now been sent to a support representative


So there is still hope.   Just in case I am looking at making a little xbmc box to hook to my TV, With just a handful of  plugins it would be far more capable than the little netgear device.  I really liked how convenient and low powered that little device was though, so it it still disappointing that

I ordered a 3D printer

A Replicator 2 from Makerbot. It is sturdily built and is ready to print in less than an hour after being taken out of the box. The only downside is that it is more expensive and more of a "prosumer" level printer than the others. It also uses a renewable plastic called PLA which has characteristics different than that of the ABS plastics.

Looking at the less expensive printers, I was not impressed by their stability and repeatable accuracy. And the time it took to begin getting reliable prints was too high for my needs. 

My plan is to learn how to make computer models, learn how to do 3d scanning of real items, and then print those models precisely on the printer.  And to have that mastered in about 6 months.  I will also be printing parts out from thingiverse.com.

 I won't get the printer for a month or two.  Waiting is tough.

Using Orange to generate association rules for a dataset.

Everything I know about association knowledge mining in Orange comes from this web page: http://orange.biolab.si/doc/ofb/assoc.htm. Let's discuss the incoming data first, then talk about how the data is processed into rules, and finally discuss what we can do with the rules once we have them. 


In the examples we used the datafile imports-85.tab. If you click on that link you will see the data file is set up in a tabular format, with tabs between each attribute or field and a newline between each data tuple or record. Once the data is set up in the tabular format you can bring the data into the program to be processed:

import Orange  
data = Orange.data.Table("imports-85.tab")  
The data must not be continuous in a column. If it is, then you have to categorize the column. You can use the following command to convert continuous fields into discrete sets of three equally populated intervals:
data = orange.Preprocessor_discretize(data, method=orange.EquiNDiscretization(numberOfIntervals=3))
To select a sub set of the data, such as the first ten columns you can specify a range like so:
data = data.select(range(10))
At this point you can convert the data into a set of rules and calculate the confidence, support and lift of every rule using orange.AssociationRulesInducer like so:

rules = orange.AssociationRulesInducer(data, support=0.78)
The data is just the set of data we have imported, maybe converted to discrete values, and maybe sub-selected a range of values. The support is the minimum support we are going to accept as a rule. If the support is equal to or greater than this support value, the rule is dropped. This conversion is based on the APRIORI algorithm from Agrawal et al.'s Fast discovery of association rules, a chapter in Advances in knowledge discovery and data mining published in 1996. This algorithm is optimized to work on the tabular format we imported. Class variables are treated like attributes by this function.

Now that we have the rules in the list named rule we can now work with the list just like any other python list. The orngAssoc module is already written to work with the rules and includes two functions to conveniently work with the rule set directly, from http://orange.biolab.si/doc/modules/orngAssoc.htm:
printRules(rules, ms = []) Prints out the rules. If ms is left empty, only the rules are printed. If ms contains rules' attributes, e.g. ["support", "confidence"], these are printed out as well.
sort(rules, ms = ["support"]) Sorts the rules according to the given criteria. The default key is "support"; you can list multiple keys.
You can also select() parts of the rule list, del() rules, append() rules.
Once you have the rules you can then filter on confidence and lift using the python lambda function, which is an way to do an unnamed function:
conf = 0.8; lift = 1.1
print "\nRules with support>%5.3f and lift>%5.3f" % (conf, lift)
rulesC=rules.filter(lambda x: x.confidence>conf and x.lift>lift)
rulesC now contains only the rules with confidence above 0.8 and lift above 1.1. Then you can sort by confidence and print out the confidence, support, lift and the rule:
orngAssoc.sort(rulesC, ['confidence'])
orngAssoc.printRules(rulesC, ['confidence','support','lift'])
These orange functions make generating association rules from tabular data almost trivially easy. You can import the data, convert continuous columns to discrete columns, and finally generate rules with confidence, support and lift. Once the rules are generated it is easy to sort, filter, and select subsets of the data and then print out the results you require.
