Remote MySQL Connections - security implications

Tiger Technologies: Remote MySQL Connections: "Unfortunately, remote access to MySQL is not very secure. When your remote computer first connects to your MySQL database, the password is encrypted before being transmitted over the Internet. But after that, all data is passed as unencrypted 'plain text'. If someone was able to view your connection data (such as a 'hacker' capturing data from an unencrypted WiFi connection you're using), that person would be able to view part or all of your database.

In particular, never store any sensitive data such as credit card numbers in unencrypted format within the database. Such data should always be encrypted, even if it's never going to be transmitted over the Internet. Encrypting the data will ensure that it stays confidential even if the raw database file is ever stolen or compromised."

Which is best for Django? Nginx or Apache?

Which is best for Django? Lighttpd or Nginx? Or maybe something else? - Server Fault: "mod_wsgi is recommended way to get Django application into production. Apache's mod_wsgi is much better than nginx. You can't find official package (in current Linux distributions) for nginx's mod_wsgi and You need to compile it by yourself.

Using nginx to serve cached files from WP Super Cache

Using nginx to serve cached files from WP Super Cache

How To Speed Up Wordpress With Nginx And WP Super Cache | tech.nocr.at: "What we have essentially done is taken the load of serving static files like images, css, and js files off of apache and passed it on to Ngnix which runs a lot faster and leaner than apache for serving static content. All requests for any dynamic content like php still gets passed on to apache. Clean and simple.

In closing let me mention that this is just what works for me, i’m sure that there might be a better way to use WP Super Cache and Ngnix to speed up Wordpress, but what you see above has really helped with the load on both of the tech.nocr.at front-end web servers."

If you’re like me, thinking about doing Git over WebDAV probably just left you scratching your head. I think the reason why this is advocated, is because of the way DH setups SSH accounts. By doing git over SSH to a DH account, only one person would be able to remotely push changes, which is fine for my needs. But, if you need to give multiple users access for pushes, then WebDAV would technically work for you. But, I opted not to go down this route."

It has a lot of cool features, which you can't get in other blog engines or will get with difficulty (consider feed by union of tags, eh?). And of course it is actively developed so release are not that far away (we'll base on Django 1.0.1, which was released in November).

Git vs. Mercurial

Mercurial has no --amend option!

Git vs. Mercurial: Please Relax � Important Shock: "In contrast to git’s philosophy of providing a flexible platform built out of individual components, Mercurial is monolithic and (relatively) inflexible. Developers who like to keep their system clean will probably appreciate the fact that hg installs one binary in contrast to the 144 that make up git, and developers who think that git’s ability to edit your previous commits is moronic, unnecessary, and dangerous will appreciate the simplicity hg provides by omitting that particular feature.
Compared to git, hg’s branching, merging and tagging systems are equally powerful and only slightly slower. The only current flaw in Mercurial’s branching system – and sweet crouching Jesus, is it ever a huge flaw – is that deleting named branches is unbelievably difficult: as far as I can tell, the only way to do so is to learn and enable the patch-queuing system (about which I have heard raves, but have not had the time yet to sit down and grok) and use the hg strip command, or install the local-branches extension. Selenium currently recommend you use tags instead of branches, which practically redefines the concept of a half-assed solution."

While at first I thought I was losing all the benefits of reusable apps, I quickly realized they were still there.

Things that improve the app go into the main repository for reuse in the next project."

Django - versioning apps in your project

Interesting tidbit here on how to keep versions of apps used in your Django project.

Django, Pluggable Apps, and Code Re-Use - O'Reilly ONLamp Blog: "My thoughts on code reuse were to create a repository of apps that you can just plug in. For example, for stuff that I work on, I'll probably create a 'jeremymjones.apps' package and have something like jeremymjones/apps/gallery/work/ and jeremymjones/apps/gallery/release/ directories in an SVN repository. I'd then probably create a Makefile (or something comparable - looking at scons right now) for the project and tell it which revisions of which apps it should include. And when you build a release for a project, it'll pull down the versions of the apps you want. Anyway, I know that's clear as mud. We use something like that here at work. Maybe if I hammer out the process (especially using scons), I can blog about it or write an article or something."

Breadcrumbs in Django apps

newbie question about breadcrumbs -
Django users |
Google Groups
: "The breadcrumbs for your own apps should not involve pulling anything
from the admin. �Just put the top two breadcrumbs (/ and /mysite) in
your site-wide base.html, then pull that into your app templates using
{{ block.super }} and append the app-specific breadcrumbs.
Carl"

That sounds ike a good idea.

This one looks way more complicated than it needs to be.

Here's an option for flatpages:

Custom template filter to generate a breadcrumb trail for a flatpage. Say you have a series of flatpages with URLs like /trunk/branch/leaf/ etc. This filter looks at the URL of a given flatpage, figures out which of the leftwards text chunks correspond to other flatpages, and generates a string of anchored HTML.

Usage:

{% load make_breadcrumb_trail %}

{{ flatpage.url|crumbs:flatpage.title }}

This one also seems a bit complicated.

This is a fairly simple way to do it.

And this is the simplest way to do it I think:


{% block breadcrumb %}{{ block.super }} » {{ object.title|title }}{% endblock %}

How to implement breadcrumbs in a django

how to implement breadcrumbs in a django template? - Stack Overflow: "In most cases, a well-defined URL can be trivially broken into a nice trail of breadcrumbs. Indeed, that's one test for good URL design -- the URL can be interpreted as breadcrumbs and displayed meaningfully to the users.

For a few view functions, where we present information that's part of a 'many-to-many' join, for example, there are two candidate parents. The URL may say one thing, but the session's context stack says another.

For that reason, our view functions have to leave context clues in the session so we can emit breadcrumbs."

So for example if I need to copy two things on a website and paste it into two separate fields on another website, I would be able to copy both of those things and then paste each of those into their own fields on the other site.

Unfortunately, there's no way to do it, barring software that does way more than that and is unwieldy and otherwise not worthwhile.

I found this discussion, which didn't produce any good leads.

If anyone else knows how it might be done, please leave a comment.

Mosso - web hosting in the cloud

Never heard of this web hosting service before, but sounds interesting. Sort of like Amazon web services. Not sure how they differ on pricing. Will have to look into it later. Have heard some good things about Mosso.

Cloud Solutions, Cloud Service, Clustered Servers @ Mosso: "Backed By Rackspace
What we wanted to do was pretty complex, so luckily, we had the support of Rackspace, an industry leader that currently manages over 30,000 servers for customers all over the world. (Well, it wasn't all luck, really. We both worked at Rackspace as our day jobs, so we knew those folks well.)

We took the Mosso vision to Rackspace's leadership team, who agreed to fund development of the new venture, and lend Rackspace's expertise towards engineering and perfecting the platform.

Because Mosso | The Rackspace Cloud needed to cluster servers in a very unique way, the partnership with Rackspace proved invaluable. They have a large amount of expertise with advanced Windows and Linux configurations, and their Zero-Downtime Network has lived up to its name for over four years."

Efficient String Concatenation in Python

Efficient String Concatenation in Python: "Building long strings in the Python progamming language can sometimes result in very slow running code. In this article I investigate the computational performance of various string concatenation methods.

In Python the string object is immutable - each time a string is assigned to a variable a new object is created in memory to represent the new value. This contrasts with languages like perl and basic, where a string variable can be modified in place. The common operation of constructing a long string out of several short segments is not very efficient in Python if you use the obvious approach of appending new segments to the end of the existing string. Each time you append to the end of a string, the Python interpreter must create a new string object and copy the contents of both the existing string and the appended string into it. As the strings you are manipulating become large this proces becomes increasingly slow.

What other methods are available and how does their performance compare? I decided to test several different approaches to constructing very long strings to see how much they vary in efficiency."

$100M in sales for top Facebook application maker

Wow, I had no idea you could make that much money on Facebook applications.

FT.com / Companies / Media - Facebook brings in payment system: "Users are increasingly spending real money buying virtual goods and credits on the applications that run on Facebook’s platform. Zynga, the largest applications developer on Facebook, with 42m users of its games, is reported to be nearing annual sales of $100m. Together, developers working on Facebook’s platform are expected to make more than $500m this year – perhaps more than Facebook itself."


The question of how Facebook will monetise its significant traffic has dogged the company of late. But last week Mark Zuckerberg, Facebook chief executive, said his company had been profitable before interest, tax, depreciation and amortisation for five quarters and was expecting revenue growth of 70 per cent this year. He said Facebook would be cash flow profitable sometime next year. Outside estimates put 2009 income at about $500m.


Wow, $500M revenue and they can't eke out a profit on that?

Send screenshots and captures direcltly to Flickr from Snagit

In order to send screen captures directly from snagit to Flickr, you need to install the Snagit Flickr profiles.

Snagit Profile for Flickr: "How the Snagit to Flickr Profiles Work

The Snagit to Flickr profiles are contained in a single, free download for current Snagit users.

Once the profiles are installed, choose a Snagit to Flickr profile to take a capture, and then click the Done button in the Preview Window. Snagit uploads the capture to Flickr, and also pastes the link (URL) for the image to your Clipboard. From there, you can paste the image link into an e-mail message or an IM conversation.

If you want to share the image on a Web page, rather than by e-mail or IM, you also have the option to copy the image’s HTML to your Clipboard, so you can insert it into the source code for your Web page."

gtkShots is a python/GTK application to capture screenshots continuosly

"gtkShots is a python/GTK application to capture screenshots continuosly.

gtkShots is a python/GTK application to capture screenshots continuosly. It is a hand tool to automatically save the screenshots in a (un)specified period of time, with the possibility to schedule it and to choose options for each screenshot to be saved, such as the size, the parent folder and the time interval between them.

gtkShots could be used for a lot of different aims, for instance to create presentations, to monitor desktop activity, or for any other scope that needs a screenshots sequence.

gtkShots is actually a GUI frontend to pyshots, my command-line python script to do the same job. Thus, if you need to work on the terminal sessions, you could take advantage of this.

Cost to render a computer-animated movie is $22,000

Since I was looking at Blender recently. I thought it would be interesting to see what the actual cost of making a feature-length computer animated movie would be.

Using the calculator on this render farm's website, I found the cost for rendering a 90-minute movie is $22,000

So computer-generated movies can be sort of expensive to produce. Even though you're not using cameras or dealing with film processing, rendering a movie is fairly expensive. And who knows how many times you may need to render it...

Then you need voice actors and so on, so it's pretty much as expensive as making a non-animated feature film, and probably takes much longer.

How to Write a Bookmarklet tutorial

This is a pretty good introduction to writing a bookmarklet.

Juhu Kinners � How to Write a Bookmarklet: "What are Bookmarklets?

All web browser support the special “javascript” URL protocol. If you type “javascript:” followed by JavaScript code into a browser’s location bar, the JavaScript will be evaluated in the context of the active web page (host page). Such strings are handled by the browsers just like any other URL. You can set them as “href” of a link tag and of coarse bookmark them. To get a feeling of this try typing this in the URL bar:

javascript:alert(document.getElementsByTagName('title')[0].innerHTML);
This will alert the document’s title. The bookmarklet’s JavaScript has full access to the document’s DOM and is run in the same JavaScript namespace as all other JavaScript in the host page."

Using Vim folds - Vim fold commands

Using folds in Vim or gvim can be very helpful. Here are the commands to remember.

Vim folding commands:

zf#j creates a fold from the cursor down # lines.
zf/string creates a fold from the cursor to string .
zj moves the cursor to the next fold.
zk moves the cursor to the previous fold.
zo opens a fold at the cursor.
zO opens all folds at the cursor.
zm increases the foldlevel by one.
zM closes all open folds.
zr decreases the foldlevel by one.
zR decreases the foldlevel to zero -- all folds will be open.
zd deletes the fold at the cursor.
zE deletes all folds.
[z move to start of open fold.
]z move to end of open fold.

Google to Sell e-Books, Move into E-Commerce

Move Over, Amazon? Google Aims to Sell e-Books - BusinessWeek: "The plan to sell e-books is the latest indication of Google's attempt to expand beyond online advertising and gain a toehold in e-commerce, where Amazon.com (AMZN), eBay (EBAY), and Wal-mart.com (WMT) hold sway. 'Google's core growth rate is slowing, and it's starting to look for the next big growth driver,' says Laura Martin, an analyst at Soleil Securities Group. In February, Google's YouTube said it is testing ways to let people sell video through the Google Checkout online payment system. Google is also testing Google Product Search, which lets consumers locate the cheapest products at various online stores. Google also runs Android Market, a store that sells mobile-phone applications."

This is a troubling development because Google has an essential monopoly on search and can use their search supremacy to drive customers to their own e-commerce and content sites. They can lock out everybody else.

The FTC needs to regulate the activities of online search providers. Not just Google, but other ones as well, and make sure that their businesses remain limited to search so that they do not infringe on competition in the online space.

Google is great, but it would be terrible if it becomes the monopolist of the 21st century.

It takes 1-5 years to render a computer-animated movie!

I was taking a look at Blender and was curious about CG rendering in general, and what the budget would be for making a computer-animated movie. In particular I was wondering about the rendering expense. I looked at the Wikipedia article on computer-animation and found that it takes 1-5 years to render a movie!!


A large number of workstations (known as a render farm) are networked together to effectively act as a giant computer. The result is a computer-animated movie that can be completed in about one to five years (this process is not comprised solely of rendering, however).


Wow, that's a long time!

Make Firefox better than Google Chrome - more screen space!!

I got some ideas from this post on LifeHacker. but didn't find it necessary to use everythng they did and went further to get more screen real estate.

What I like about Chrome is the fact that there's more space for you to see the web page. The excess "chrome" ironically has been removed. The Window's title bar is gone, the status bar is gone, and so that opens up a lot of space.

So all I wanted to do was get the same amount of real estate in Firefox, but I ended up with more!

How?

First, under the Firefox View menu, uncheck Status Bar. That gives you a bunch of extra space at the bottom of the window. And now you're getting close to emulating Chrome.

Of course you wont' see the status of the page as it loads, but that's the price you pay. BUT you can install Firebug, in which case you would have much better status information accessible anytime by pressing F12.

Second you need to install

Personal Menu by Merci Chao (Version 4.1pre)

What that does is allows you to hide the menu bar, which is what Chrome does, that gives a bunch of space at the top of the page. After installing Personal Menu make sure you go back into View and unselect Toolbars > Menu Toolbar

Now that hides the Menu bar, which you can still get to by pressing ALT.

Now you're almost there.

Next, you go back into View > Toolbars and unselect Navigation Toolbar.

Now, lo and behold you have more space in Firefox than you have in Chrome!!!

Isn't that awesome? Do you really need the navigation bar? No, because if you want to type something there, you press the CTRL-L shortcut anyway, and that continues to work.

You can also install this:
https://addons.mozilla.org/en-US/firefox/addon/8769

That will allow you to toggle the navigation bar using the F2 keyboard shortcut. Very handy!!

That's the one feature I wish Chrome would have-the ability to toggle the navigation bar. If Chrome did that, the amount of screen real estate would expand tremendously.


ps, You can use this theme if you want your Firefox to look more like Chrome:

"Too new browser" fix for UPEK password bank (Firefox 3)

Very soon after I bought my Dell laptop which has a fingerprint reader by upek. And it's convenient password bank, I upgraded to Firefox 3 and it immediately stopped working. It's a bummer that the UPEK fingerprint reader password bank doesn't work with Google Chrome, but it's nice at least to have it working on Firefox.

The error that you get after upgrading Firefox is:

“Following browsers were found, but not supported in Password Bank
Too new browsers:
Firefox 3.0 (en-US)”

To fix it you need to find out what version of UPEK fingerprint reader suite you have running. If you're lucky, it's a version that has a download available on the UPEK site which will sort of patch your installation. If you're not lucky they tell you to go beg your hardware vendor for the download.

Welcome To UPEK - Support - Customer Support - Knowledge Base: "Firefox 3.0.x is supported by following versions of Protector Suite QL:

PS QL 5.6.2
build 4447 and higher (Native support - extension is a part of the installer. Go to Control Center -> PasswordBank to enable the support.)
any older build (Updated libraries has to be installed. See instructions below.)
PS QL 5.8.2
build 4445 and higher (Native support - extension is a part of the installer. Go to Control Center -> PasswordBank to enable the support)
build 4024 for Toshiba (PasswordBank extension has to be installed manually. See instructions below.)
any older build (PasswordBank extension has to be installed manually. See instructions below.)
PS QL 2009
native support in all available builds (Go to Control Center -> Applications -> PasswordBank -> Settings to enable the support.)"

To install:

- intended for PS QL 5.6.2 only
- for Firefox 3.0

To install updated libraries for PasswordBank, please close psqltray.exe process using Microsoft ProcessExplorer (Ctrl+Shift+Esc) and copy contents of the ZIP file to the Protector Suite QL installation directory (usually C:\Program Files\Protector Suite QL\ or C:\Program Files\Fingerprint Reader Suite\). You need to overwrite two files:

1) pwdbank.dll in PS QL's root directory (C:\Program Files\Protector Suite QL\pwdbank.dll)
2) pbgk1_9.dll in "browser" sub directory (C:\Program Files\Protector Suite QL\browser\pbgk1_9.dll)

Once files are replaced, please reboot your computer! After reboot, please check, that Firefox support is enabled in PS QL (right-click on PS QL tray icon -> Control Center -> Settings -> User Settings -> PasswordBank).

Is Myriad Pro a "web-safe" font?

Is Myriad Pro a "web-safe" font? That is, do both Windows and Mac users have it installed?

Myriad (typeface) - Wikipedia, the free encyclopedia: "Since the launch of the eMac in 2002, Myriad replaced Apple Garamond as Apple Inc.'s corporate font. It is now used in all of its marketing and on its products (See Apple typography). More recent iterations of the iPod (from the iPod photo onward) have used Podium Sans, which has similarities with Myriad (as opposed to Chicago), for its user interface. A different humanist sans-serif typeface, Lucida Grande, is used as the system font for Apple's Mac OS X operating system. Myriad was included with third generation of iPod.[3]
Myriad is also used in the corporate identities of Wells Fargo, bragster, and Modern Telegraph, as the primary headline typefaces of those companies."
