I created an InterMapper probe that detects whether a web server is vulnerable to the Heartbleed bug. You can read about it on my Blueberry Hill Software blog at:
Why can’t the IRS tell me how much has been reported? Various companies and entities forward the same information to me and to them. If only I could look at the IRS’ notion of what has been reported, I could avoid rummaging around for all those scraps of paper at tax time.
Well, now you can. The IRS Get Transcript site allows you to get a list of all the accounts, forms, etc. that have been filed in your name.
Go to the site, create an account in the obvious way. My confirmation arrived within seconds, the entire signup process took two minutes. Then you can browse your records, both for the current tax year and for previous years (including your past tax returns).
My MacBook Pro (10.9.2) was running slowly. I saw frequent spinning beach balls, systemstats was consuming 100% of the CPU on a regular basis, Apple Mail was grinding away indexing files, etc.
The forums at discussions.apple.com contain all kinds of dicey recommendations about
rm -rf /.Spotlight-V100 followed by “Works for me!” and “Didn’t work for me!” I’m not averse to wading in with Terminal, but I’d rather get advice from a trusted source.
One of the advantages of having AppleCare (you get it for 90 days after you’ve upgraded to a new OS, such as Mavericks) is that you can call 800-275-2273 and speak to a knowledgeable person. They recommended that I do three things:
- Boot into safe mode, and let the computer perform a thorough disk and permissions check. (See the Apple “What is Safe Boot, Safe Mode?” article for more info.)
Force Spotlight to blow away and rebuild its index.
Then let Apple Mail re-index.
To do this:
- Boot into Safe Boot mode. Restart your computer and hold down Shift until you see the Apple and the progress bar that indicates that the hard drive is being checked/repaired. When the OS starts up (probably many minutes later), you’ll see “Safe Mode” in red text at the upper right corner of the screen. Restart your computer.
To force Spotlight to rebuild its index, simply open System Preferences, click Spotlight, then the Privacy tab. Add your hard drive (hit the “+” and select the hard drive). Then close System Preferences. Re-open System Preferences, and remove the hard drive from the Privacy tab. This is the cue for Spotlight to begin re-indexing. In a moment, you can click on the Spotlight magnifying glass to see that it’s rebuilding the index. (Rebuilding took about three hours on my system.)
Leave Apple Mail closed during all this. (You don’t want to have them both indexing at the same time – it hammers the processor and prolongs the agony.) When Spotlight finishes its indexing, open Apple Mail to allow it to re-index its cached files. You can continue to work in Apple Mail while this happens.
My system has been much more responsive since I did this, and I didn’t have to try any odd suggestions.
I’ve been looking for a way to sort out Angular, Backbone, Bower, Grunt, Node, NPM, Yeoman and all the other buzzwords that get thrown around for writing a Single Page App for the web. There are many Youtube videos around: these videos stand out as excellent resources.
- Intro to Angular.js in 50 Examples (Part 1) The evolution of a complete Angular.js application, starting from bare HTML, successively adding a slight improvement to each example to build a compelling result. This video goes through Example 36 – I anxiously await Part 2! Created by Curran Kelleher in March 2014 as a lecture for an undergraduate course at UMass Lowell. His code for these samples are on github.
HTML5 Polygon Editor using Backbone, Require.js, and Canvas A minimal but complete graphical editor using Backbone.js, iterating through several steps to build up the final example. Also by Curran Kelleher, presented in April 2013.
Yeoman Bower and Grunt – Building Modern Webapps With Ease This gives an overview to using the packaging tools that manage the various modules required by modern web apps. Shai Reznik presented this as part of Google Developers Group (GDG) Meetup in May 2013. His slides are at http://goo.gl/CtrHG
Leave a comment with a link to other resources, and I’ll add them to this list.
What a great weekend! What interesting ideas came from the H@ckfest!
My team, the inforMED project, presented an idea for helping first responders (EMTs, ED triage) to get relevant data on their cell phone/tablet when they first encounter a patient. If the patient has one, the EMT would scan the token (RFID, QR code, NFC, etc) and this would immediately bring up a face sheet that give contact information, current medications, allergies, and advance directives to that they could initiate appropriate treatment.
We won an honorable mention for the CIO Track of the entire competition, and also won a $1,000 prize from Intel. The team members were:
- Rich Brown
- Adrian Gropper
- Jake Mooney
- Susan Katz Sliski
- Jessica Wang
- Joyce Zhang
- Alice Zielinski
- Patrick Zummo
What a great team!
I was accepted to the Joslin Diabetes team at the MIT Healthcare Grand H@ckfest this weekend at MIT Media Lab.
It’s an all-weekend opportunity to work with a team on projects related to solving the problem of diabetes. Should be a blast!
I took the time to incorporate the feedback from my previous post to load the newest CeroWrt firmware and re-run the tests.
This image gallery shows the results of the RRUL performance tests. There’s a lot of analysis in the note on the CeroWrt-devel mailing list at: https://lists.bufferbloat.net/pipermail/cerowrt-devel/2014-March/002396.html
[Note: This is an earlier result. Check out the subsequent posting for CeroWrt 3.10.28-16 (above)]
The postings below are a series of charts that were created by the netperf-wrapper program. Note: I don’t know why the upload charts show such fragmentary data.
All charts made with default Queue Discipline: fq_codel, simple.qos script, ingress ECN on, egress ECN off. Variations are primarily with the Link Layer method.
DSL Modem has sync rate of 7616kbps down/864kbps up.
Chart names have the form:
- Down is the entered download speed (kbps)
- Up is the entered upload speed (kbps)
- Dflt is the default Queue Discipline as described above
- Link is None or ATM with the number of overhead bytes [0 | 44]
- try is an optional second or third attempt
