Small WiFi webcam for quasi-outdoor use
I’d like to have a webcam pointed toward my house, so that I can check (via Safari on iPhone) if I left the garage door open, if there’s a package on my doorstep when I’m off on a business trip, etc. My idea is to place a small webcam inside the electric gaslight in front of my house. General requi…

I own a Linux workstation which currently has 4 GB of RAM and planning to go for 8 GB in the near future. CPU is a . Should I install a 32 or 64 bit variant of Linux?
How do I setup Ubuntu/Linux's Network manager to selectively route network traffic through the VPN?
I'm using Ubuntu 9.04 and I just noticed that ALL of my network traffic is being routed through my VPN. I would like the VPN to route only the traffic hitting servers on the VPN and then connect directly to anywhere else on the internet as needed. The VPN is PPTP VPN that is run using some sort of …
Optimizing Windows 7 for SSD
I have Windows 7 RC1 running on a solid-state-drive (SSD) on my laptop. I've seen various recommendations for tuning the OS to take advantage of the SSD. There are a few obvious ones, such as disabling defragmentation, and some controversial, such as disabling page file. Thought that this would be …
Disable CD eject button on Windows laptop
Most laptops have a CD eject that is very sensitive, and placed such that it regularly gets triggered when handling the laptop. This is in particular a problem (for clumsy-handed me) when picking up the laptop to stow in in a laptop bag; I've lost count of the number of times it has ejected just as…
Android push notifications stop working after app updated to FCM v1 API
Push notifications stop delivering after migrating from the deprecated FCM Legacy API to FCM HTTP v1. The server sends requests but Firebase returns 200 — yet notifications never arrive. The v1 API uses OAuth 2.0 service account authentication instead of a server key. Apps that simply swap the endpoint without updating the authentication mechanism will get silent failures.
When would you use apt-get remove over apt-get autoremove?
I understand that removes packages and is to remove any packages that were installed to fulfil a dependency for a given package. So for example if I installed LibreOffice and it had dependencies on say Java and installed it as part of the installation when I run the command , why would I run the co…
Fastest GZIP utility
I'm looking for the fastest (or zip) utility. I have a LVM volume which 95% exists out of blank 's, so compressing that is very easy. I'm looking for the most fastest solution, and don't really care of the compression except the 's. I'm aware of (same as ) but was wondering if there's any faster me…
The Notepad++ tab bar keeps hiding
Is there a way to always force the tab bar to show? I go to Settings → Preferences → General → Tab Bar and uncheck hide, but the next time I open Notepad++, the tab bar is gone, even if I drag multiple files into the window.
How to disable Windows 8 lock screen?
So I took a plunge and installed Windows 8 Consumer Preview on my main home PC. So far so good, but there is one annoyance - the system "locks" the computer after a period of inactivity causing me to re-enter my password. I really would like to avoid this, but have no idea how. I already tried the …
Supresss the 'no such file or directory' message from 'find'
I'm trying to find a directory with this command: I see a huge amount of 'No such file or directory' output. Is there a way to make find shut up if it doesn't find anything?
Per-application audio control that works in Windows 7 64 Bit
Added: Last item that I could not gain (per-app) control of is "System Sounds" I do not know what executable or window to "talk to" to control this item. On Windows 7, I'm still looking for a per-application adjustment of the focused program audio playback with control capability. Preferably it sho…
Is there any quality difference between PNG vs BMP image formats?
I have just learned that PNG is a lossless image format while BMP can be both uncompressed or lossless format. Should there be a quality difference between these two? If not, does it mean that other lossless formats like TIFF, JPEG2000 and PNG offer the same quality as BMP?
Should I defrag the hard drive running on a Virtual Machine?
I know that there is no point (in fact it is a bad idea) to run Defrag on an SSD. What about a virtual machine running on an SSD, should I defrag it's hard drive since it is basically accessing the Hard Drive the same way?
Page numbers in a PDF are off, how can I change them?
I have a digital edition of textbook I bought. The pages are numbered from 1 - 570. As a result, when I search page 68, it shows page 51 as the first pages originally in the textbook aren't numbered and there's a whole index of some numbered as . What can I do to edit this textbook, or change the p…
VirtualBox Scroll Up/Down Guest Terminal
I have a FreeBSD guest on a Windows XP host. BSD has no GUI, so it just boots up to the terminal. The output of most commands is more than is visible on the screen, but I can't scroll up/down in the terminal through Page Up / Page Down, or SHIFT + Page Up / Down keys. I have to keep running command…
`alias rm="rm -i"` considered harmful?
I have read some time ago (can't find the reference) that using such an alias as was very bad. Is there historical evidence or common sense explanation for that fact? I would imagine that it gives a user a bad habit of relying on the confirmation prompt to check his command, which could lead to dis…
Mac OS X not reporting directory sizes correctly?
In Finder, I've noticed that if I duplicate some .app files (in the Applications folder), Finder will show that the duplicate .app file is not the same size as the original. This file size discrepancy does not happen for all .app files that I duplicate, but it seems like the larger the .app file, t…
Windows explorer sees different file name from cmd
I just got a new computer, and put my old hard drive (which contained Windows) in the new computer to keep my old files. I was successfully able to remove the Windows directory from this drive, but I'm having some trouble here. I am using Windows 7. Basically Windows Explorer seems to see different…
Is there a way to disable custom webkit scrollbars?
Is there an extension, custom user stylesheet, etc. that will disable or revert the customization of scrollbars in Webkit based browsers like Google Chrome? I like the plain, native scrollbars but I cannot seem to find a combination of CSS to make them come back once they have been styled by CSS.
