comment Can zero-filling reset wear leveling of USB sticks / Flash drives?
Since a 2k block (which seems to be a common unit of size for a block) of data can be all zeros the could be reduced in a way that might resample TRIM and the information (even all zero is information) can be stored in a 1byte infomration else in memory. Those "zero" blocks could be used for wear-out cycling. Of course the block cannot be used for data writing as this else would virtually increase the memory and fail once the blocks again are filled with data. But the logik to special trade a certain patter ("all zero is just one pattern in 2k") it could be used to boost wear-out-protection.

comment Can zero-filling reset wear leveling of USB sticks / Flash drives?
In your last paragraph you say "Nope, just that cell." ... before you state that the most flash/USB memories sticks work on 2k Blocks. What do you mean by cell. loss of 1 byte (=1 cell) or loss of 2k bytes (=1 cell = 1 2kblock)? Besides I think you state much truth sticks are not really user-distinghisable to their quality and hence smarter solutions like some sort of TRIM or else zero-field resetting technique (as stated in another answer) is not incentivated...

comment How to reduce the size (disk space) of Windows 8
I would very much like to test your suggestion, if only I could :) Being -as yourself- a huge "fan of disabling" I ended up disabling Windows itself my linux setup is much leaner. ::: ::: Anyways does DISM is not related to system restore, is it? Deployment Image Servicing and Management (DISM) Do you know what it actually does or how come you run across it? You would not have stopped something for mere guessing, did you?

@JuhoÖstman Thanks for pointing out this pitfall. Being aware of the problem... have you run accros a solution? would small enough messages be a way to make it likely to work?

comment UDP traffic through SSH tunnel
@grawity Thank you for pointing out this option, which even when as pointed out by philpirozhkov the required root login. I wonder if there can be a way to trick it into not needing the root?

comment find any script which is running for more than say 30 minutes in Linux System
hi @umlaute, your script gives on my box (standard Ubunut 12.04 setup) a "ERROR: Unknown user-defined format specifier "etimes"". What do I do wrong?

comment Using Linux, should I place commonly-used files on an SSD?
This is a good answer. Quite often I forget the caching linux does. One additionall adivce: having /tmp residing in RAM as a tmpfs can allow your applications to have a "playground" that does not cause any wearout. This then can be used for the browsercache location.

comment USB 3 stick in USB 2 port
I would think that getting 60MBps as theoretically possible is rather a little overoptimistic expectation. I cannot tell the general thing, but my personal exerience is that 20MBps was the best I could get with USB2.0 connections (though I expect the hardware connected, drives etc to have been quicker, so USB 2.0 being the bottle-neck)

comment Can zero-filling reset wear leveling of USB sticks / Flash drives?
thank you for explaining the part (that questions are intented for a broader audience) and I am sorry I took it wrong. Indeed I really enjoy that there has been at least an attempt to answer the question. Is this "power USB on often" related to the "height increases flash-cell lifetime" issue, or how did you mean it? thanks

comment Can zero-filling reset wear leveling of USB sticks / Flash drives?
thank you. I cannot understand why you explain to me that it is not mechanical/magnetic? (My question surely was not as dumb as to provoke I would not know this already). The question is actually about the specifics of the "wear leveling" and how a zero-fill (assuming a certain firmware) would indeed be able to reset the device. I just cannot accept that once writen to all blocks a stupid "wear-leveling" would never recover. Hence I think there must be something like a "TRIM" or reset (via zero-fill) for "good Usb-sticks"

comment Turn Javascript into bookmark or bookmarklet?
bookmark is not very specific. There is more than one program that knows something like a bookmark/bookmarklet. Of course it seems that you mean a browser. Well there is Firefox, IE, Opera etc.. which one?

comment Can you tell by the network traffic whether a video was watched or downloaded from YouTube?
@ Karan :thanks for the consolation. Still I am confused to see a downvote on an "not-wrong" even partly helpful answer of mine. Instead of downvoting I would rather see better answers to be voted up. I am confused, since I though the site works the way that wrong answers are downvoted.

comment Can you tell by the network traffic whether a video was watched or downloaded from YouTube?
why the downvoting? It answers the question by showing an example of a case where it is different. At least it thereby partially responds to the question. It took some work to use wireshark and investigate this. I feel unappreciated for this work.

comment Can you tell by the network traffic whether a video was watched or downloaded from YouTube?
I see no reason why it should be impossible to make youtube-dl use https connections. Still the handling of https is a little more tricky and as it seems not required to achieve the goal (to provide a mechanism to download the resource). In the current way it would still not achieve the side-goal of downloading the data an "mimic video watching way". This goal (even with using https-connections) would not be achieved since I doubt the elaborate behaviour of the browser is immitated. I think youtube-dl is more like small python app.

I have to give this browser cache some background research. Maybe this way I can find a way / software which when downloading does not generate any difference to the simple watching of a video.

comment How to reduce the size (disk space) of Windows 8
funny! :) investigting myself I found the C:\Windows\System32\DriveStore directory and wondering about "if this is a way to save space" I ended up on your answer to my very own posting. Great

comment How to reduce the size (disk space) of Windows 8
Deleting temporary files is good. Though I would like to focus on the less obvious things like unused driver softwae and help files... I have "too much" disk space usage on a clean install, meaning no temporary files I can delete

comment How to reduce the size (disk space) of Windows 8
I mentioned the pagefile.sys and the hiberfil.sys to provoke some thinking and to share already ways to safe diskspace (when you have enough RAM - maybe4GB - you can dispense of the pagefile.sys). The pagefile.sys can be disabled via Control Panel\System and Security\System and selecting "Advanced System Settings". There one can disable swapping via the Advanced->Performance settings found in this dialoge. If the RAM is enough there will be no noticable effect and about 3-4GB more diskspace

comment SSD AES-256 hardware encryption - how to configure?
maybe man hdparm will yield some results. I am not sure but there are two parameters mentioned there: One is --security-unlock PWD and the other --security-set-pass PWD. Also bear in mind that by trusting the AES in your drive you trust the company which made the product. With a modern AES_NI enabled intel cpu you might at a slight expense be able to have a maybe more trustworthy protection. Of course all depends on the value of your data :)
