Here are some useful packages I came across in recent years:
Link clearance, and closing some browser tabs 😉
A Hassle-Free Way to Self-Host Google Fonts
A Quick Spreadsheets-to-HTML <Table> Tool
Test regular expressions with real-time highlighting.
Port scanner shows which ports are open on your (or someone else’s) computer and what they are accountable for.
Verification is performed via the scanner nmap, and shows the extend to which your PC is open to the outside world.
If you were ever curious about the software driving the Mars rovers, I came across a good question on Programmers today.
The JPL LaRS lab provides a couple of documents on coding standards and monitoring, and NODIS has a document on Software Engineering Requirements. The Workshops on Spacecraft Flight Software also offers a couple of slideshow presentations.
I find this topic very interesting (how would you debug a piece of code that is executing on a different planet?), but unfortunately there are not that many related questions (and answers!) on Programmers.
What about the Soviet space program?
I admit it was very tempting to celebrate the 404th post on this blog, rather than the 400th. Just like 1024 instead of 1000.
Incidentally however, recent events mean that the 404 jokes may turn into reality as two proposed bills are discussed and probably passed in the US.
Normally we stay away from from politics here at the official WordPress project
but the proposals of SOPA and PIPA have serious impacts on the way we can use the internet. From the Wikipedia article:
Threat to online freedom of speech
Negative impact on websites that host user content
Weakening of “safe harbor” protections for websites
General threat to web-related businesses
Threat to users uploading content
Threat to internal networks
Threat to free and open source software
Ineffectual against piracy
Deep-packet inspection and invasion of privacy
Negative impact on DNS, DNSSEC and Internet security
No doubt that in recent days SOPA is covered more frequently in online tech magazines:
See Ars Technica for stories about some supporters of the bill
At least one of the upcoming episodes of The Daily Show promises some fun. Can’t wait for January 18.
When I developed my YuJisho online dictionary web application, I was looking for freely available fonts and dictionary data related to CJK languages.
For my dbscript database schema management application, I tried to find as many database schema samples as possible to test the application against.
There is a lot of data (raw, processed and visualized) available on the Internet, but occasionally it is hard to find. This raised the idea of providing a collection of references to free data sets on the web like the Guardian Data Store, and I was thinking about a platform to provide such links.
Now news is out that data.gov plan to release their platform as open source software (GitHub), but the code is still labeled as alpha. (data.gov HTML says it is based on Socrata, which also provides lots of links to open data).
Let me know what’s your experience with OpenData, or similar platforms.
While searching for appropriate string comparison functions in TSQL, I came across these pages implementing a couple of
string functions: Capitalize, Center, Count Substring in String, EndsWith, ExpandTabs, IsAlnum, IsAlpha,
IsDigit, IsLower, IsTitle, IsSpace, LJust, LStrip, RFind, RJust, RStrip, Strip, SwapCase, Title, Zfill
and string tuple functions: Split, SplitLines, Within, EndsWith, StartsWith, Contains, Join, Parts, Partition, RPartition
See here for more TSQL articles by the authors.
In a web application with its custom CSS that also defined hyperlinks, Internet Explorer would render disabled hyperlinks greyed-out, whereas Firefox showed them as normal text.
Tracking down this different behavior, I found that you can define CSS styles not only by class and tag, but also by attributes using the [attribute] notation:
*[disabled], a[disabled]:hover, a[disabled]:visited
If you are looking for CSS definitions for fixed headers, footers and sidebars, take a look at these sample CSS. I’m thinking about including them in the next version of dbscript.
Recent posts covered collation support and Unicode in SQL Server.
Just a couple of links with more information on this topic:
This seems to be a re-occurring topic on Stack Overflow: where can you get free fonts for Unicode characters?
There may be some misunderstandings on Unicode and fonts and Unicode fonts which cause the question, and makes the answer more difficult than you would expect:
From the Unicode website:
The Unicode Standard is a character coding system designed to support the worldwide interchange, processing, and display of the written texts of the diverse languages and technical disciplines of the modern world.
The standard defines 107,361 characters or code points as of version 5.2. Unicode also defines a set of properties for each character, and algorithms such as line breaking.
Fonts that “support Unicode” promise to the operating system or to the application that uses them that they provide an accurate graphical representation (glyph) of the code points they implement. A “Unicode font” typically does not cover each and every Unicode code point, but rather only subsets of the standard (Unicode Blocks).
Typically it is the operating system’s responsibility to find a matching font when displaying Unicode text.
So how can you find a free Unicode font supporting most of the characters? Here’s a list of links:
- Hanazono (52,809 CJK characters, full Ext A, Ext C, partial Ext B)
