Java equivalent of Csmith
Csmith generates random but valid C programs for compiler testing. Is there an equivalent out there that generates Java programs? ECS LIVA Z (talk) 00:06, 14 March 2017 (UTC)

Windows 7 keeps making my pictures smaller
I have windows 7 and I noticed that windows had created several folders on it's own and named them things like Example_file or (it's not example but I am using it as a example) for screenshots I made or other photos. If I saved photos from a certain site or of a certain person it would put them in that file.

The problem is when it does this it makes the photo smaller and there does not seem to be a way to enlarge it back to its full size without it becoming all pixalated from being stretched. How do I stop it from doing this with my photos and reverse the compression/minimizing it has done to my photos?--Sara203040 (talk) 02:50, 14 March 2017 (UTC)


 * Sounds to me like it's creating a library of thumbnail images, for use on icons. If so, the originals should still exist elsewhere. StuRat (talk) 03:57, 14 March 2017 (UTC)


 * I use Windows 7 and have not seen this happening. I don't think Windows 7 is the culprit.
 * Sounds to me as if you're saving web pages (i.e. html files) containing thumbnails, while you're under the (incorrect) impression that this would also save the full size images the thumbnails link to. It may help if you describe exactly how you save these photos. Jahoe (talk) 13:55, 14 March 2017 (UTC)

I am not saving html files, it does sound like it creating thumbnails, but I don't see the original anywhere. It has changed the original. How do I prevent it from automatically doing this in the future and fix my existing pictures?--Sara203040 (talk) 21:04, 15 March 2017 (UTC)
 * Could you tell us where you're getting the pictures from and exactly what steps you're taking to save them? ᛗᛁᛟᛚᚾᛁᚱPants   Tell me all about it.  21:06, 15 March 2017 (UTC)


 * Nearly every digital camera can take pictures of higher resolution than the average notebook screen can display at once. Users should handle files, not screenshots. Note, when reading out the cam, ensure You are copying the files, not interpret a snapshot to have no losts on copying and resaving the image. Handle a digital camera as an USB memory device to access the files as they are. Also note what happens to the EXIF information from camera. -- Hans Haase (有问题吗) 11:15, 16 March 2017 (UTC)
 * Are you saving images from a web page? Be aware that a lot of sites will contain two or more versions of the same image: a low-res one that is shown on a page, and a higher-res one that can be displayed by clicking on the first image.  If you are right-clicking on the first image and saving it, you will be getting the smaller, low-res version.  Example: on this page there is a photo of a painting of a ship.  If you right-click on the picture, you can save a small file called "300px-Anonymous_The_Noord-Nieuwland_in_Table_Bay,_1762.jpg".  If instead you left-click it, you will be taken to a larger version of the same (1024px-Anonymous_The_Noord-Nieuwland_in_Table_Bay,_1762.jpg), which you can save instead.
