Ifttt.com and platform reminiscing

I’m playing around with ifttt.com and it is intriguing. I remember an earlier effort, yubnub, that I always found compelling. A general script interface to all my Internet data and services so that I can do interesting things across sites […]

Scientific computing and the cloud

This year I’ve had a chance to experiment with tools for compute intensive applications. In particular, tools that harness the profusion of inexpensive CPU/GPU cycles available — OpenMP for multi-threading on single machines so that multiple cores can be leveraged; […]

Software tips

* “How to unhide your Library in Lion”:http://tidbits.com/article/12306?rss — chflags nohidden ~/Library. Yay. * “Making desktop web apps with Automator”:http://ihnatko.com/2011/07/22/making-desktop-webapps-in-lion/. All kinds of goodness in here. * “BBEdit 10 is out”:http://www.barebones.com/products/bbedit/bbedit10.html. Purchased. * “Marked”:http://markedapp.com/ seems like a super useful companion […]

Software Lenses and Lytro

I’ve wished for years that someone would come up with a “software-defined lens”:http://theludwigs.com/2003/07/camera-as-a-data-gathering-device/. A surface that would capture all inbound photons and let me decide later about focus, depth of field, etc. It looks like “Lytro”:http://www.lytro.com/ has done it or […]

Playing around with GPU programming

Been spending a lot of time playing around with GPU programming for scientific computing the last couple weeks. Fascinating stuff, GPUs are computational beasts. Some observations: * If you want to get into it, “GPGPU.org”:http://gpgpu.org/ has boatloads of great info […]

Math software sources

Saving for later reference…. * “Netlib”:http://netlib.org/ * “NIST”:http://gams.nist.gov/ * “Trilinos”:http://trilinos.sandia.gov/ * “PETSc”:http://www.mcs.anl.gov/petsc/petsc-as/ * “OpenCL”:http://www.khronos.org * “Nividia OpenCL”:http://developer.download.nvidia.com/compute/opencl/sdk/website/samples.html * “Apple OpenCL”:http://developer.apple.com/library/mac/search/?q=opencl * “NERSC”:http://www.nersc.gov/nusers/resources/software/. ACTS stuff dead?

Recent Software Trials

* “gfxcardstatus”:http://db.tidbits.com/article/11982?rss to let me fiddle with macbook pro graphics hardware. which is proving to be problematic. Why does the browser (Chrome) require the high end power-consumptive nvidia chip? Seems like this feature of the macbook is a waste if […]

Software to try over the holidays

* “Printopia”:http://www.ecamm.com/mac/printopia/ to enable printing to any printer from iphone/ipad (via “Tidbits”:http://db.tidbits.com/article/11829?rss&utm_source=feedburner&utm_medium=feed&utm_campaign=Feed:+tidbits_main+(TidBITS:+Mac+News+for+the+Rest+of+Us)) * “Textastic”:http://www.textasticapp.com/ code editor for the iPad (via “Read/Write Web”:http://www.readwriteweb.com/hack/2010/12/code-editors-for-the-ipad.php?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed:+readwriteweb+(ReadWriteWeb)) * “Postbox”:http://www.postbox-inc.com/ email alternative for OSX. * “Momento”:http://momentoapp.com/, a diary app. (via “TechCrunch”:http://techcrunch.com/2010/11/28/momento-app/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed:+Techcrunch+(TechCrunch)) * “A whole bag of […]

Year end link clean up

* “Poor Halo play prompts stabbing threat”:http://blog.seattlepi.com/seattle911/archives/231642.asp. Doesn’t seem unreasonable. I’ve heard campers threatened with worse. * “How Secure Is My Password”:http://howsecureismypassword.net/. No idea how accurate, but fun. 17 thousand years for my typical password. * “Rich on photobooks”:http://www.tongfamily.com/archives/2010/12/photobooks-for-christmas/. I […]

Recent software trials — Camino, Shuffler, GIT, Wisestamp, Microsoft Windows Live Sync

* Firefox is feeling increasingly bloated, maybe because I’ve got a bunch of plugins jammed in. But trying out “Camino”:http://db.tidbits.com/article/11548?rss&utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+tidbits_main+(TidBITS%3A+Mac+News+for+the+Rest+of+Us)&utm_content=Google+Reader on the Mac, seems cleaner and lighter. * “Shuffler.FM”:www.shuffler.fm. Eh, streaming music just doesn’t work for me. My primary listening […]

Moving off of Matlab for numeric/image processing

Reardon abused me (not really) for still using Matlab and goaded me to look into the ImageJ world. So I am learning. Seems like I need to get smart on * “ImageJ”:http://rsbweb.nih.gov/ij/ and the “Fiji”:http://pacific.mpi-cbg.de/wiki/index.php/Main_Page distribution * Python derivatives like […]

Recent Software Trials

* “Default Folder”:http://db.tidbits.com/article/11217?rss&utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+tidbits_main+%28TidBITS%3A+Mac+News+for+the+Rest+of+Us%29&utm_content=Google+Reader — OK i really wanted to love this. But visually very funky. Ended up nuking. * “PopCharX”:http://www.ergonis.com/products/popcharx/. This is one utility I can’t live without, and the new version with favorites is nice. Software I haven’t tried […]

Mech Eng basics on the web

Taking Finite Element Analysis this term which would be way easier if I actually had ever taken a basic course in mechanical engineering. Beams, trusses, springs, cantilevers are all foreign to me, I was learning about resistors and capacitors when […]

Signs of strain at Google?

OK the missteps that Google has made with Buzz this week are well chronicled. They jammed a product out without really thinking it through. That doesn’t hit me that much as a user. But today using the iphone map app […]
