  • News on the Jewel v. NSA Case | Irreal
    specific cause is a violation of the Fourth Amendment Now the EFF is arguing to a federal judge that there are enough agreed upon facts to reach a constitutional conclusion and they are asking the judge to rule the NSA s actions unconstitutional They argue that the NSA s actions amount to a general warrant a legal device that the Fourth Amendment was specifically written to prohibit There s no question that the EFF has the facts on their side but it is far from certain that the judge will rule in their favor Still at least the case is moving along and offers hope that these illegal actions will be halted There appears to be positive action in Europe too The European Court of Human Rights has demanded that the GCHQ justify its mass surveillance Meanwhile seven ISPs have filed complaints with Britain s Investigatory Powers Tribunal about GCHQ s monitoring of Internet communications something the GCHQ has been worrying about for some time One can only hope that their fears are realized This entry was posted in General and tagged Privacy Bookmark the permalink Quantum Theory and Computational Complexity git timemachine Search for Recent Posts Elisp Summary Emacs for Prose FISA Abandons the Fourth Amendment Again Blogging with Org Mode and Nikola How to Keep Emacs Running Across an X Crash Recent Comments Mike Zamansky on Blogging with Org Mode and Nikola Phil on How to Keep Emacs Running Across an X Crash Sebastian Christ on European Quotation Marks NoonianAtall on A Hyper Key on Any USB Keyboard Kris on An Example of Why Reproducible Research Matters Links Useful Emacs Commands Archives April 2016 March 2016 February 2016 January 2016 December 2015 November 2015 October 2015 September 2015 August 2015 July 2015 June 2015 May 2015 April 2015

  • Quantum Theory and Computational Complexity | Irreal
    systems in reasonable time He shows that it is indeed impossible providing P NP The article outlines the argument in terms accessible to those not expert in quantum mechanics To my mostly uninformed mind this provides a persuasive argument for the notion that P NP It s not a proof of course but it is persuasive If you have the slightest interest in the P NP problem or are fascinated by the counter intuitive results of quantum mechanics I m sure you ll enjoy the article This entry was posted in General and tagged Tech Bookmark the permalink Advanced Programming Mode Implementation News on the Jewel v NSA Case Artur Malabarba A quick comment from someone in the area This is just my understanding and I have no problem with being argued wrong The complexity of solving a quantum Hamiltonian does indeed relate to the NP hard problems However the blog rather overstates the meaning of this Namely 1 The assumption that P NP does not limit the size of quantum states 2 The assumption that macroscopic quantum states like the mentioned cat state exist does not imply P NP The reason is the simple fact that there exists a quantum system which implements the solution of its own NP hard Hamiltonian does not imply there exists an efficient algorithm for this task jcs I m a complete laymen in this area so I m in no position to argue for or against the position posited in the article I do find the connection between quantum theory and the arguably most important problem in CS fascinating though Search for Recent Posts Elisp Summary Emacs for Prose FISA Abandons the Fourth Amendment Again Blogging with Org Mode and Nikola How to Keep Emacs Running Across an X Crash Recent Comments Mike

  • Emacs Themes | Irreal
    my eyes so I changed it to oldlace and I ve been happy enough with the result that I haven t made any further changes Still I occasionally run across a tweet or post praising some theme and I always take a look at the screen shots So far I haven t seen anything that I like more than my simple non theme but I ll doubtless keep looking at themes people like and point out on the Web Now Yuriy Pitometsu over at the Google Emacs Community points to a very nice site that has screen shots and information on several themes If you re new to Emacs or unhappy with your current theme you should take a look Each page of the site lists several themes along with a thumbnail screen shot so you can easily find themes that interest you Clicking on a theme brings up a larger screen shot and more information It s a very nice resource if you re in the market for a new theme Recommended This entry was posted in General and tagged Emacs Bookmark the permalink Unicode Font Redux Advanced Programming Mode Implementation Search for Recent Posts Elisp Summary Emacs for Prose FISA Abandons the Fourth Amendment Again Blogging with Org Mode and Nikola How to Keep Emacs Running Across an X Crash Recent Comments Mike Zamansky on Blogging with Org Mode and Nikola Phil on How to Keep Emacs Running Across an X Crash Sebastian Christ on European Quotation Marks NoonianAtall on A Hyper Key on Any USB Keyboard Kris on An Example of Why Reproducible Research Matters Links Useful Emacs Commands Archives April 2016 March 2016 February 2016 January 2016 December 2015 November 2015 October 2015 September 2015 August 2015 July 2015 June 2015 May 2015 April 2015 March

  • Unicode Font Redux | Irreal
    Malabarba suggested a simpler solution I was happy with unicode fonts but couldn t resist the one line solution that Lee and Malabarba offered So I disabled unicode fonts and added the line set fontset font fontset default nil font spec size 20 name Symbola to my init el It worked perfectly of course so I uninstalled unicode fonts and went with the Lee Malabarba solution Malabarba notes that the documentation for set fontset font is a bit opaque That s an understatement I had to read it several times before I could figure out why it worked for my problem No matter If you re having the same problem you can just think of it as a magic incantation This entry was posted in General and tagged Emacs Bookmark the permalink Fast Toggling Emacs Modes Emacs Themes Roland Walker Thanks for the prompt I had always intended to improve startup of unicode fonts el by adding a higher level of caching I just tagged v0 4 2 which is on its way out to MELPA now Marmalade is broken for me these days With the additional cache there is no perceptible delay for me after the first invocation If you keep your one liner above a good practice is to always disambiguate by adding a trailing colon to the font name eg Symbola This keeps Emacs from interpreting any part of the font name as a property jcs Thanks for the update and for the advice about adding a colon to the font name Search for Recent Posts Elisp Summary Emacs for Prose FISA Abandons the Fourth Amendment Again Blogging with Org Mode and Nikola How to Keep Emacs Running Across an X Crash Recent Comments Mike Zamansky on Blogging with Org Mode and Nikola Phil on How to

  • Fast Toggling Emacs Modes | Irreal
    is satisfied entirely by org mode because I use org edit special Xah Lee i switch modes a lot manually years ago i had key to switch between php and html mode when working in mixed html so i can get syntax coloring of the part am working on These days i had key to switch several alt modes for the same lang e g javascript because some does something better syntax table and also writing my own so i had to check behaviors and features and see how others do it Typically 3 key sequences of single keys Artur Malabarba There are some variables minor modes that are too obtrusive to keep turned on but are useful on occasion linum mode is a good example Debug on error was my example Artur Malabarba But I too am curious as to why Snader toggles org mode or text mode eric I sometimes write long emails in gnus that can benefit from some level of formatting For these I switch the message buffer to org mode compose using headings lists and maybe even text formatting When done I switch back to message mode htmlize the document and send it This is a very specific use case but having the easy to remember toggling commands is a winner because I don t do this often enough to warrant mode specific bindings jcs As Artur says some are obvious I sometimes want to see line numbers but usually not It s convenient to be able to turn it on when needed When I was learning paredit I often got stuck and needed to turn it off temporarily That doesn t happen often anymore but Artur s key map idea makes it easy to have it available As for Org mode and Text mode I sometimes want to see and Org buffer as plain text and those two toggles Make it easy to switch back and forth bakhti This is a grate idea I ve also added Ctrl x t to guide key guide key sequence jcs Adding Ctrl x t to the guide key sequence is another good idea The notion is that the third key is mnemonic enough to be remembered but if like me your memory is prone to taking extended vacations this is a good method for documenting your choices bakhti This is the thing I don t trust my memory I still can t belive hi cool this idea is I went further and did the same thing for multiple cursors I can never remember what keys I should use for it so now I have something like this Ctrl x m l mc edit lines Ctrl x m e mc edit ends of lines Ctrl x m b mc edit beginnings of lines Ctrl x m n mc mark next like this Ctrl x m p mc mark previous like this Ctrl x m a mc mark all like this And of cause Ctrl x m is also
