I have a large Excel worksheet with 1872 columns. I want to export
columns 1-6 as a csv and then repeat this process for the entire
worksheet.



All of the data is in one worksheet, there are no null values in
any of the rows or columns.



So in total there will be 312 csv files.



Thank you very much for any input or help with this question.

TL;DR



After i ran Windows-To-Go from an external hdd my UEFI firmware
probably got heavily corrupted. Neither wireless, nor ethernet, nor
bluetooth, nor touchpad are
recognized anymore. This has beeen tried in Windows and Arch
Linux.

ethernet nor wireless controller detected anymore



My computer is an Acer Aspire V5-572G (x64 processor). Can't really
tell which
motherboard i do have, because sudo dmidecode returns
command not found.



Due to the following reasons i got to my assumption the UEFI
firmware is corrupt:




  • On several different Linux live systems, Windows-To-Go and Arch on
    my
    hdd all dont show any of the devices mentioned above after
    lspci or
    in the device manager (network adapter) respectively.

  • UEFI menu behaves very strange. When pressing the key for save
    and
    exit it wont start as it previously did, but freeze for a moment
    and then power off the PC.

  • Corrupted entries in the UEFI-menu, e.g. Serial Number is 8 or
    Manufacturer is left blank.



Do i now need to flash my UEFI? If so can you give any advice? Or
do
i even have to replace the whole motherboard?



P.S. Resetting the UEFI has already been tried, with no
improvement.

My Windows laptop is connected to my home wi-fi AP. The wi-fi
router has both 2.4GHz and 5GHz bands, and I can see both stations,
plus a list of those in the neighborhood when I click the network icon
in the System Notification area.



I then set up my Android phone as a hot-spot. I connect my lap-top
to the hot-spot. Everything works out fine.



After working for about 30 minutes with no trouble, I then shut
down the hot-spot on the phone. My laptop is now unable to see the two
(2.4GHz and 5GHz) APs on my home router. Other APs in the neighborhood
can still be seen.



No amount of disabling/enabling the wifi adapter on my laptop will
make it see my home APs again until I reboot.



This problem is reproducible every time I go through the same
sequence. What could be happening?

I got stuck with a private key only in my NSS database, without a
corresponding certificate. pk12util, which I normally use
when I need to export things from the db, refuses to export the key
without a matching certificate.



This should be technically possible, although I don’t feel like
writing a program using the NSS API myself. Is there an existing tool
that can do this?

I have rebooted an iMac after it froze. The boot up fails with
errors



Bootcachecontrol unable to open /var/db/bootcache.playlist: No such
file or directory.
Bootcachecontrol unable to open /var/db/preheateduser/merged.playlist:
No such file or directory.



I found that I should be able to delete /etc/launchd.conf to get it
up and running again, but there is no such file on the disk. href="https://www.ifixit.com/Answers/View/192201/Unable+to+open+-var-db-BootCache.playlist%3A+2"

The question is a bit older, did apple move that file since then?
The system is 10.9.5

I have bluetooth speakers (Bluedio Revolution). Everything works
fine if I use just 1 application but if I start another one then the
sound can play only 1 source of sound. For example: I am listening
music online via Firefox browser. Then I am starting Chrome browser
and launch youtube. Then the music from Firefox stops playing and the
sound "switches" to the youtube. Is it possible to play sound from
both application at the same time?

It has been said elsewhere (sorry can't find my references) that
Control + e and/or
Control+k, or even F6
allow you to "jump" to the "Search" box in an existing Google search
results page (this is in Chrome). However, none of these combos work
for me (even when using Command in lieu of
Control.



I am looking to reproduce my search workflow / the behavior as seen
in Safari, below (in which I hit
Command+l, jumping to the URL bar,
which has my prior search terms)..

However, in Chrome, I just end up editing a messy URL (which
doesn't work), so I have to retype my entire search query again.

Sounds silly, but actually, cumulatively wastes a LOT of time. Any
fixes, my gurus?

I have a bunch of Security Updates in queue for Windows 7,
affecting various versions of the .NET framework. I read some of the
descriptions. Here's one:




This update resolves vulnerabilities in the Microsoft .NET
Framework.
The most severe of these vulnerabilities could allow elevation of
privilege if an attacker injects a client-side script into a user's
browser. To learn more about this vulnerability, see Microsoft
Security Bulletin MS15-118.




Security Bulletin MS15-118 says:




The most severe of the vulnerabilities could allow elevation of
privilege if an attacker convinces a user to navigate to a
compromised
website or open a link in a specially crafted email that is designed
to inject client-side code into the user’s browser.




What is meant by "user's browser" in this context? Does this
vulnerability affect any browser, not just IE?

I have several defunct Skype groups of which I am/was an admin.
I've already kicked the members and for some of them, left the group
myself. However, I still see the groups on my contact list.



I've tried hiding the conversations but these groups are still
searchable and still exist. How do I get rid of them permanently?

Drones are awesome fun. They can bring out the inner kid in
even the most jaded individual, but they can also land people in a lot
of trouble. Here are some things every new drone owner should know
before taking to the skies.
