Just tried an install of 2.77 LTS into a Centos 7 VM. When it started up, failed due to PXIX TLS error. Huh? On the plugin update. sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at sun.security.provider.certpath.SunCertPathBuilder.build(SunCertPathBuilder.java:141) at sun.security.provider.certpath.SunCertPathBuilder.engineBuild(SunCertPathBuilder.java:126) at java.security.cert.CertPathBuilder.build(CertPathBuilder.java:280) at sun.security.validator.PKIXValidator.doBuild(PKIXValidator.java:382) Caused: sun.security.validator.ValidatorException: PKIX path building failed at sun.security.validator.PKIXValidator.doBuild(PKIXValidator.java:387) at sun.security.validator.PKIXValidator.engineValidate(PKIXValidator.java:292) […]

Time to update WordPress to 4.7.3. I used the SVN method. I was using an older version of SVN and required me to update the local checkout. $ svn upgrade Fine. Did it. $ svn sw https://core.svn.wordpress.org/tags/4.7.3/ . svn: E155025: ‘svn switch’ does not support switching a working copy to a different repository svn: E155025: […]

For safekeeping, we froze leftover buttermilk into an ice cube tray. 14 cubes. Now I need 2 cups of buttermilk. Weigh a glass using my trusty triple beam balance. 280g Add two random cubes. 340g Add two more. 400g So it looks like each cube is 30g And by this table of buttermilk equivalent values it looks […]

Rhapsody, the long-suffering little brother streaming music service, recently rebranded itself as Napster. Same app, different name. Big deal. I noticed that I could not start the app with the great Launchy in my new Windows 10 install. Not sure if it worked in Windows 7. Looking at Properties of the launch shortcut, in C:\Users\Me\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Rhapsody […]

Microsoft recently published ReST API guidelines on GitHub. They are worth reading over if you design ReST APIs. My Highlights: No limit on GET URL length Error response messages (consistency is the key; note the nesting of error info) Pagination: put the link for the next page into the response JSON. Interesting Delta queries: search, apply […]

Finally beat the July 28th deadline for upgrading Windows 7 to Windows 10. Made backups with Macrium Reflect first.  Paid for that one, got rid of the perpetually flaky Acronis. Both machines (Intel Core Duo 2Ghz dual-core and old AMD dual core) upgraded successfully. AMD box slow, but it worked, with install apps and files in […]

At work I used Centos 6.4 to convert a large Subversion repo to Git. This required a VM with a 100Gb disk, more than my old iMac could deal with, to the point where I could not update to newer OS version or even run iTunes to update apps. [dchwalis@imac ~]$ df -h Filesystem Size […]

I was messing around with the WiDi driver to stream the Grateful Dead show tonite and disabled the Intel Video driver. At this point, the machine started up, did POST, did the swirly page and then a blue dim (not BSOD) screen came up and nothing. HD activity, not much else.  Could NOT get safe […]

I started getting vertical dark lines in my ADF scans on the the highly great Canon MF4570dw Laser/Multifunction. Use this to determine location of small bits of dust on your scans. Then clean the glass under the ADF guide, slide it out carefully. Print the OpenOffice file Dirty Printer Test Sheet and then feed the […]

On my new work desktop computer with Windows 7, I noticed a 30Gb file hiberfil.sys filling drive C. Since I don’t use the hibernate function, I can disable it. From a command shell as Administrator G:\> PowerCfg.exe -H off The file disappears.
