It has occurred to me that it has been two weeks since my last post. Time sure flies doesn’t it? Having a wife and kids, a business to run, and everything else that goes on, it is hard to keep up sometimes. But, don’t worry, I’m still alive and have a lot of neat things to share… I just need more time to do it! Ugh!
My birthday was this past week and, I’m not going to lie, it was pretty awesome! I got to go out to eat with family and friends and also got some cool stuff.
I get some questions from time to time, most of them I can answer by email and are not really significant enough to post on the site (as they are more specific/acute problems), but every once in a while I get a quest that I think will benefit a lot of people and so I try to post it on here for other to read.
So… What do you think?
But, since things have been really crazy lately, I’m going to ask for your opinion(s)… What type of stuff would you like to read/learn from this site? If you have an idea for something that would be interesting and useful to yourself and others, please let me know (comment below or via facebook, twitter, or email).
One of these days I need to put up some reviews on some paperbacks I’ve been reading… Some really good ones too! 🙂
I’m looking forward to your feedback guys and gals! have a great weekend!
Do you have a smart-phone (or a modern camera with GPS)? Do you take pics with it? Do you ever upload them on the internet (social networking, tweeting, forums, email) or text them? Well did you know there is (probably*) hidden data in those pics that anyone could use to track your location. Scary isn’t it?! The hidden data is referred to as EXIF (or sometimes just Meta-data) and contains information like the camera make and model, the image dimensions, and yes: GPS coordinates…
*Note: supposedly sites like Facebook and Flickr remove the EXIF data from the images when you upload them… If you are not sure, try doing a Google search with the name of the site in question and the term: EXIF to see what their policy is
I knew about this (at least to some extent), but I didn’t realize how easy it was for any individual to access that data and use it to track you down, until today. Take a look at this video:
So what to do now?!
Well, if you’re worried about pictures you’ve already uploaded, you might consider trying to remove them or at least try to change the privacy settings to try to limit who has access to these photos.
The next step would be to disable the geotagging feature of your camera (on the iPhone open Settings and go to “General->Location Services” and turn the Camera toggle off) so that no more GPS data will be tagged on the pics.
Finally it’s time to remove the GPS data from existing pictures, I’ll show you how to do that next…
Removing GPS Data (Geotags) From Pictures
I’m going to show you the FREE way, but keep in mind if this scares you (we’re going to use the command line), then there are other options out there (but I don’t have time to find them for you, sorry… the command line / terminal isn’t that scary, really)…
Step 1: Install Jhead
Get Jhead and install it on your computer. It is available for Linux, Mac, Windows and even FreeBSD.
If you are using Ubuntu you can get it straight from the repositories using this command:
(Note: if you installed it from the repos on Ubuntu, you can skip to the next step)
This is a command line program, there is no GUI (no point-click, no pretty pictures or icons, etc.), so you need to make it easy to access and use.
Mac OS X
If it goes anything like my download did, it might have a “.txt” extension on the end, and it will be in your Downloads folder. Do whatever you like, but I moved mine to a folder I use for command line utilities like this: /Applications/Utilities/NoGUI/ is my directory of choice. Assuming your situation is like mine, here are the commands to make the file executable, rename it, and move it to that destination:
//Open Terminal, defaults to your Home (user directory)
chmod +x Downloads/jhead.txt && mv Downloads/jhead.txt /Applications/Utilities/NoGUI/jhead
note: if you get an error about there being no such directory, then it’s because you don’t have a NoGUI folder yet, so make one like this:
now it’s not going to be much fun typing out: /Applications/Utilities/NoGUI/jhead every time you want to run the command… so let’s make an alias to simplify things. I’m going to assume you don’t have an alias for your text editor of choice yet, and I’m also going to assume you don’t care for command line / terminal editors like Vi, Vim, Nano, or Emacs, so we’ll do it the ugly way once, then we’ll go ahead and create a alias to the TextEdit as well to make this easier for you in the future.
In your terminal… you should still be at your Home (user)… run the following to backup your bash profile and open the profile (not the backup) in TextEdit:
Now, go to the bottom of the file and on a new line enter the following lines:
alias supertext='sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit'
Now Save and Quit. You should now be back at the terminal. Now Quit Terminal and then Open it again. When it reopens you the new aliases should have loaded. To be sure type: alias and if it worked you will see all available aliases listed in the output. Now you can skip to Step 2.
I haven’t tested this on Windows, but there is an executable listed on the page so download it and put it in the root directory of your C: drive. If you want to set up an “alias” for it on Windows, you could try making an environment variable/path for it using the info found here. But for the rest of this guide, I’m just going to assume you put “jhead.exe” in “C:\” so for all of the commands below you will navigate to the directory where your photos are and then will run “C:\jhead.exe ” followed by the rest of the command, the path to the image will stay relative to your current directory.
Linux (other than Ubuntu)
I’ll update this later if I have time… but for now I’ll just have to assume you know how to install things on your own distribution or at least know how to look it up. Sorry.
Step 2: Remove/Modify EXIF Data From Pics
Locate the files you want to modify and then navigate there in your terminal or command prompt. (use Terminal in Linux or Mac, and use Command Prompt — cmd.exe — in Windows).
Once you have changed directory (cd in case you forgot how and you can use ls in Linux/Mac or DIR in Windows to list the files in that directory if you want) and then test the Jhead installation and alias by testing on a photo:
If it works you will see some output like this:
File name : somePhoto.jpg
File size : 244792 bytes
File date : 2010:06:23 03:12:16
Camera make : Apple
Camera model : iPhone
Date/Time : 2009:11:13 09:30:18
Resolution : 1200 x 1600
Aperture : f/2.8
GPS Latitude : N 00d 00.00m 0s
GPS Longitude: W 00d 00.00m 0s
======= IPTC data: =======
City : G
Record vers. : 2
Object Name : IMG_0004
Now, obviously I changed the GPS data for this example… But it’s definitely there… for now!
Please note: All of the following commands are for BATCH processing (doing multiple files at once). You may need to change the extension from “.jpg” to “.JPG” depending on your operating system and the way your files are named. As far as I know Jhead only works with jpg/JPG/jpeg/JPEG files.
If you only want to process one image at a time, just substitute the file name of that image for the “*.jpg”
Here’s the code to remove the stuff we don’t want/need
To remove the EXIF/GPS data (but keep basic info like pic size and date/time) use this:
//for Mac or Linux
jhead -mkexif *.jpg
C:\jhead.exe -mkexif *.jpg
To remove do the same as above AND add your own comment use this:
jhead -mkexif -cl 'Your Comment Goes Here - and Keep the Single Quotes!' *.jpg
C:\jhead.exe -mkexif -cl 'Your Comment Goes Here - and Keep the Single Quotes!' *.jpg
If you want to remove EVERYTHING you can and leave just the bare-minimum to display the image, use the following:
Well I mentioned recently that I was going to make a new theme for the site and here it is! To go with the new theme I also changed the navigation. Now the menu is sorted by topic only and is pretty straightforward. (If for some reason you liked the old “Antidote” category posts, they are still here, just under “Tech Stuff”).
Some of these new sections are empty — as in there are no posts there yet — but that will change in the near future. I now have another author to help add content to this site, so stay tuned.
For comparison I have included some small screenshots of the old and new themes with a new poll for you to vote and tell me what you think. If you have ideas/suggestions to make it better, feel free to leave a comment, or contact me via twitter, facebook, or email. Thanks!
Hello everyone name is Jeremy, some know me better as T. But more on that later *nods*
Well First I want to say it’s awesome to be here on Alex’s Antidote! he made me aware of this site the other day when I made a post on Facebook about the passing of Dwayne McDuffie (RIP). Since then I’ve looked over the board and in talks with Alex I’ve decided to jump on board as a writer/author here. I look forward to talking about some of the things I personally love to enjoy in life; Comic Books, Movies, and TV shows/cartoons. I may sometimes post something on Sports just to annoy you all, but it’ll be mostly about Comics.
A little bit about myself, I’m almost a quarter century old and I am from Michigan. I love American Football especially the University of Michigan, but really i’ll watch any football game if/when i can. I enjoy reading all kinds of comic books (Specifically X-Men titles, Teen Titans, JLA, GLcorps, and anything with Static in it). My favorite comic book character is Static from Milestone/DC comics and second favorite is Cable from Marvel comics. I really like watching movies, mostly action/comedies. I’ll watch any cartoon/tv show for at least 2 episodes before completely giving up on it, i call it my 2 ep rule because i believe after 2 episodes i can usually gauge whether or not i’m going to invest my time in this for the long haul. Leverage, Detroit 1-8-7, Chuck, and House are probably my favorites right now, though my watching list on Hulu is much longer lol
So anyways, enough about me. I hope you are all ready to endure my thoughts and opinions on things!
It is getting to the point where I can’t stand being on Facebook any more. It seems I can’t be on there for more than 10 minutes without something like this popping up on my news-feed! I am beginning to wonder if I am the only sane/rational person in this world… Or am I the one who’s lost it?
You know exactly what I’m talking about (well you should if you’ve spent 5 minutes on the internet). I really shouldn’t have to go into great detail about this topic, so I’ll keep it simple — if nothing else, but for my own sanity — and get this rant over with.
“Dude, what are you ranting about?!”
The current trend is simple. Someone posts something (generally on facebook, but it happens on other sites too) and somewhere near the end of the statement it will say “Re-Post this if you agree” or “Like this if you agree” or some flavor of “re-post” and/or “like” in the form of a command… And without fail people cannot help themselves! People, millions of them, re-post and/or like these things, many of them re-posting the same (or very similar) things over and over in the span of days (or even on the same day)!
This is getting ridiculous!
This stuff comes in different shapes and forms. Here’s a quick list (shortened to topic/idea, because I have no patience for this):
You’re not my friend unless you re-post/like this
You’re not a Christian — I.E. you’re ashamed of Jesus — if you don’t re-post/like this
*Some random percentage in the 80’s to 90’s range* % of people will not re-post this (and you don’t want to be one of THEM)
Facebook/Myspace/Etc. is going to start charging you money so re-post to share with everyone
Some other serious, but most likely not true, “fact(s)” that you must re-post or you’re heartless and part of the “system”
Some catchy phrase or funny joke — but re-post it because I told you too (not because you liked it)
Parody re-reposts (basically like above only mocking/making fun of the above)
And etc. etc. etc….
I’ve seen this with text-messages too… I’m sure this still happens in emails too, but I think that may be dieing out. I know I’m not the only one who remembers the Urban Legend Chain-Emails form the 90’s right? Wow those were annoying! Oh yeah, and Bill Gates wants to give you money just for forwarding this email on to everyone of your contacts… my friend is a lawyer and verified this is true and legal (pft yeah right)…
I once tried to come up with a reasonable/logical conclusion as to why people constantly take part in this… But then I gave up because it was a pointless quest.
I have loved ones and friends who do this so I have been quite about it for a very long time, but I can’t take it any more! I am calling for a moratorium on this nonsense! Of course, no one is going to care about that or what I have to say… So instead here’s a quick poll for you, perhaps your answers can help me make sense of it all… oh yeah, and after you do the poll… since I know you can’t help yourselves… RE-POST THIS ON FACEBOOK / MYSPACE | and ETC! 😉
