Peter Norvig - Teach Yourself Programming in Ten Years:
“Why is everyone in such a rush?
Walk into any bookstore, and you’ll see how to Teach Yourself Java in 7
Days alongside endless variations offering to teach Visual Basic,
Windows, the Internet, and so on in a few days or hours. […] The
conclusion is that either people are in a big rush to learn about
computers, or that computers are somehow fabulously easier to learn
than anything else. There are no books on how to learn Beethoven, or
Quantum Physics, or even Dog Grooming in a few days. […]
Researchers
(Hayes, Bloom) have shown it takes about ten years to develop expertise
in any of a wide variety of areas, including chess playing, music
composition, painting, piano playing, swimming, tennis, and research in
neuropsychology and topology. There appear to be no real shortcuts:
even Mozart, who was a musical prodigy at age 4, took 13 more years
before he began to produce world-class music.”

Henri Sivonen - HOWTO Avoid Being Called a Bozo When Producing XML:
“There
seem to be developers who think that well-formedness is awfully hard -
if not impossible - to get right when producing XML programmatically
and developers who can get it right and wonder why the others are so
incompetent. I assume no one wants to appear incompetent or to be
called names. Therefore, I hope the following list of dos and don’ts
helps developers to move from the first group to the latter.”

François Joseph de Kermadec - I’m wikied out:
“Wikis
and Forums are awesome. They allow the community to improve the
documentation, build upon it, provide feedback to the developer. But
they cannot replace the documentation. By definition, a Wiki is written
by someone who feels comfortable enough with the application to need
“tips", forums require long searches to extract information: none of
these wonderful concepts can replace linear, logically organized
documentation.”

Marc Hedlund - Etsy’s Excellent Visualizations:
“I had seen Etsy,
the marketplace for handmade goods, but not its excellent
visualizations, until Upendra showed them to me this week. Check these
out:
* Etsy ColorSpace
* The 3d Etsy Time Machine (I love that the clock runs backwards)
* The Etsy Geolocator“

“The Next Generation of Genealogy Sitebuilding
("TNG") is a powerful way to manage and display your genealogy data on
the Internet, all without generating a single page of HTML. Instead,
your information is stored in MySQL database tables and dynamically

Joe Gregorio at XML.com - Dreaming of an Atom Store: A Database for the Web:
“Imagine
that you just have a huge glob of storage that you can store Atom
Entries in, and which you can edit using the APP, and then search over
using OpenSearch. That idea, that big blob of Atom Entries, all
editable and searchable, is an Atom Store.”

Tony Marston - An activity based Workflow Engine for PHP:
“This
document will describe the activity based workflow system which I have
constructed as an extension to my Development Infrastructure for PHP.
[…]
In order to implement a workflow system it is first
necessary to find a suitable means of designing and modeling a workflow
process. For this I take advantage of the work done by Carl Adam Petri
who was the first to formulate a general theory for discrete parallel
systems which gave birth to what are now known as Petri Nets.”

PostgreSQL Gotchas:
“PostgreSQL
is a fully-featured, robust open-source database with strong SQL
standards compliancy. As with all RDBMS products it has its odd little
idiosyncracies, which while documented, are not obvious,
counter-intuitive or just head-scratchingly odd.”
I’ve already
run into some of the problems described there - “unquoted object names
fold to lower case", and “COUNT(*) very slow".

Neil Kandalgaonkar - Links to essays in Best Software Writing I:
“Joel Spolsky has compiled a book of essays on software, which he calls The Best Software Writing I.
The essays all came from online sources, but when Spolsky released the
chapter listing, I didn’t see anywhere online where he posted links to
the originals. So here they are.”

In “On Browser UIs”, Richard S. Tallent has a comprehensive list of reasons “why web apps suck". On “missing widgets":
“Tree
views: even the best ones out there suck. MSDN, for example. They also
almost invariably lead to using frames to avoid population and
rendering on each page refresh. […]
Context menus. This alone
is responsible for any number of cases of over-busy interfaces in web
apps. Without the right-click ability (sorry Mac users), the interface
must display every possible action and provide an alternate method of
selection. Combined with a lack of drop-down menus, the result is a
busy interface that must show too many possible-but-unlikely actions.”

Marcus Baker - Listen kids, AJAX is not cool:
“If
you writing a user interface, make sure it responds in 1/10th of a
second. That’s a pretty simple rule, and if you break it, you will
distract the user. […]
Suddenly we have lot’s of web
developers “enhancing” the browser experience with behind the scenes
XML fetching back to the original site. I cannot think of a worse
collision of technologies than low level user interfaces with requests
over the internet. The delays and failures of internet traffic are
especially painful in this environment and, from the AJAX demos I’ve
seen, the developers aren’t helping. […]
I don’t think I am
alone in being habituated to the way the web behaves as pages. When you
write AJAX applicatons you drive a horse and cart through one of the
most successful metaphors of all time.
AJAX has possibilities,
but it’s not there yet. Not as a community and not with the tools. Web
developers cannot become GUI developers overnight. We need time.”
Ajax Blog has a good follow-up - AJAX: telling it like it is…:
“The
more I think about it, the more it’s clear that some kind of delaying
HTTP proxy, that I was suggesting here, is badly needed to make people
see how badly AJAX can suck when you inject a little latency -
AJAX@localhost is always going to look good. […]
From where I
stand, Javascript is today where it should have been about 5 years ago
as people were discovering DHTML - you can now write code which has a
pretty good chance of running under all the modern browsers for the
sake of neat web page gimmicks. But what Javascript isn’t is a sane
environment for building MVC applications where the data model is
available courtesy of AJAX. […]
Of course this not going to
stop anyone from trying - we’re talking holy grail here. But what is
worth remembering is if you decide to go AJAX, realize that you’re
significantly increasing the risk that your project will ‘fail’.”

Andi Gutmans - PHP OCI8 Driver Updated!:
“Antony just sent an email that he finished commiting the updates to the PHP OCI8 driver and giving a short overview of the bug fixes and improvements.
The
OCI8 extension has had a lot of bugs in the past few years, and it
became clear that if this extension was to become supportable, it would
need a serious face lift and architectural improvement.”

“This web service software
takes multiple word processor files (typically .doc) and converts them
to Oasis OpenDocument v1.0 format, and then optionally runs them
through an XML pipeline. The result is returned in a .zip file.
Docvert builds upon OpenOffice.org because it has the best chance of dealing with the vagaries of the MS Word format.”

Jon Udell at InfoWorld - WinFS and social information management:
“I
saw my first demo of Microsoft’s Cairo OFS (Object File System) back in
1993. It was briefly unveiled at the Professional Developers Conference
that year, and then shelved. This week I installed the beta version of
its successor, WinFS.”

Roger A. Grimes at InfoWorld - Time for a stand-down review:
“I
propose that one of the best cost/benefit security moves any company
can make is to take a step back, review the current security
configuration of its assets, and fix the basics before looking into
more advanced solutions. Spending a week or two doing this can provide
immediate returns, compared with waiting for a three-year payback on an
unproven device or solution.
I have to admit that this idea
isn’t my own – it’s stolen from the military. For example, every few
years the military suffers from a spate of “random” incidents such as,
say, airplane or helicopter crashes, accidental weapons fire, or
unpredictable cases of post-traumatic stress. When management (the
generals, admirals, or commanders) note a spike in such events, they
often order a stand-down, which requires the entire affected force to
drop all non-essential duties for the entirety of the stand-down period.
Everyone
must re-examine current SOPs (standard operating procedures) to see if
they need to be modified or, more likely, how they aren’t being
universally applied. Either way, after the stand-down review period,
the spate of random incidents always seems magically to decrease.”
