Transferring Videos to an iPad with a Flash Drive

I was wanting to transfer a few videos from to my iPad that were on a USB Flash Drive for later viewing. I happened to have a Lightning to USB 3 “Camera” Adapter, and thought, “Hey, this will be handy!” I plugged the adaptor into my iPad and the flash drive into the adaptor. The iPad automatically launched Photos to import from the Flash Drive, but I was quickly told my flash drive was empty!

I googled the issue, and found that others were having the same issue.

Luckily, they proposed a solution: because the adaptor is a “Camera” adaptor it excepts files to be named using the DCF system. Simply put, the Flash Drive should have a folder called “DCIM”, and the name of the file should be exactly 8 characters long without the extension (no spaces), just like a camera created it. (For example, DCIM\my-movie.mp4.) Voil√†, plug in the flash drive and now it allows me to import the videos!

Sadly, the video only import into the Photos app, rather than Videos. But, it still allows you to view the video.

SSH client for an Emacs user on iOS

I tested two SSH clients (Prompt 2 and Termius, previously known as Serverauditor) for iOS on an iPad Pro (12.9 inch) with the Smart Keyboard.

Both Prompt 2 and Termius have very similar features and work just great doing basic ssh tasks.

However, I am an avid GNU Emacs user, and only Serverauditor worked out of the box to allow me to use Emacs (i.e., can use option as the meta key). Prompt 2 leaves the Option key as an option key, and inserts “funky” characters instead of being a meta key.

I was a little saddened by this as I find the Prompt 2 interface a little nicer (more customizations in the user interface). So, like every question, a solution has already been posted on the internet.

I found the following StackExchange post on how to translate the resulting characters to Meta+symbols (e.g., option+a yields a å, however I want it to be Meta-a).

Adding this code to my .emacs file at least allows me to use Prompt 2 for emacs. However, some keys are not able to be completely mapped. For example, “Option + e” cannot be bound to M-e, because that key tries to make an accent, which Emacs cannot not seem to intercept correctly.

I asked the Prompt 2 developers about re-binding Option to a Meta key, and their answer was “I’m afraid there’s no way to change/bind/unbind keys on the keyboard right now. … Your best bet in this case is to use the on-screen keys to use meta or ESC.” They must have never used Emacs, because clicking on-screen for a meta key is not even close to a solution.

Overall, both Prompt 2 and Termius work great as SSH clients. But, if you want my recommendation: use Termius (Previously known as Serverauditor).

Cannot Resize Outlook 2010

I recently came across a problem where my Outlook 2010 window became a toolbar and I could not resize the window to see my mail:

Outlook 2010, Toolbar Only

I could press the Minimize, Maximize, and Close buttons, but I could not resize the window because it would only let me move the bar.

To solve this problem, I pressed Alt + Space, clicked “Size” in the toolbar that appeared and pressed the down key a few times and then Enter and the rest of Outlook appeared below the toolbar. I was then able to resize Outlook with a mouse like normal.

Getting Mathematical Symbols in Office 2007 (For Windows)

There are a lot of math symbols that I find myself wanting to use in either Word or PowerPoint documents and the typical symbol table is rather small and does not have fun things, like “bowtie”.

Though, these symbols are there; they are just hidden. To access them, go to “Insert” -> “Symbol”.

A new window should popup which has a list of symbols in it that you can insert… But, like I said, not a lot of them. To unlock more, click on the drop down box next to “Font:” and select “Cambria Math”. This list has a lot more math symbols in it. Just scroll through to find what you are looking for, or use the “Subset” drop down box to find the area where the symbol you are looking for is at.

This will work in both Word and PowerPoint.
Though, Word has an even faster way of accessing these symbols, just by typing \SYMBOL in the document (Like LaTeX). It is something called “Math AutoComplete”

It can be enabled by in Word, clicking the circle in the upper left hand corner, and going to “Word Options”.

In the menu, select “Proofing” and then press the button “AutoCorrect Options…” From there, select the tab “Math AutoCorrect” and check “Use Math AutoCorrect rules outside of math regions” and “Replace text as your type”.

Now in Word when you typing something and want to insert a mathematical symbol, just do what you would normally do in LaTeX. Type in “\bowtie”, followed by a space and it will appear!

You can then copy these symbols from Word to PowerPoint. So, it makes it a little easier than finding things in the symbol table.

Though, their list does not have everything LaTeX does so sometimes you still have to use the table.

Hope this helps someone out there!

Always ask really does mean always ask!

A little thing with Windows Vista Security Warnings is their ability to popup even if you tell them not to!

Everytime I start PuTTY by double clicking on the file,I get a Security Warning saying “The publisher could not be verified. Are you sure you want to run this software?”

PuTTY Folder
putty-security

I always click “Run” because I like using PuTTY for connecting to my school computer. The PuTTY I’m using is coming from a trusted source so I decided to uncheck “Always ask before opening this file.”
Sure enough, next time I open the program again I get the same security warning.

There is a way to fix this though.

To do this, you must “Unblock” the application from it’s original file location. By original file location I mean the location where you downloaded it to. If you move the file before unblocking, you will never be able to unblock the file unless you delete it and redownload the file. If the file you need to unblock came in a zip, you need to unblock the zip before extracting the contents.

To Unblock an application, right click on the file and goto Properties. In the general tab, click Unblock.

Now you can move the application to any folder you want, and will not get the annoying popup ever again!
