Backporting from Python 2.3 to Python
2.2

Backporting from Python 2.3 to Python
2.2 06/08/2004 11:18 PM

We have a home-grown templating system at work, which I intend to dedicate an entry to some time in the future. We originally wrote it in Python 2.2, but upgraded to Python 2.3 a while ago and have since been evolving our code in that environment. Today I found a need to load the most recent version of our templating system on to a small, long neglected application that had been running the original version ever since it had enough features to be usable.

Unfortunately, this application was running on a server that only had Python 2.2. Installing Python 2.3 would have been somewhat more painful here than on other servers we run for reasons I won't go in to, so I decided to have a go at getting our current code to run under the older Python version.

In the end, I only had to make three minor changes, all at the top of the file in question.

1. I added from __future__ import generators as the very first line of the file. We use generators (with the yield statement) in a few places - this feature was only properly added in Python 2.3, but was made available in Python 2.2 as a "future enhancement" through the aforementioned obscure import.

2. I added True, False = 1, 0 on the next line down. Surprisingly, Python 2.2 had no support for a boolean type and instead used a test for non-zero instead. The above line defines constants that behave enough like Python 2.3's True and False to avoid any problems.

3. I defined an enumerate function, which was introduced for real in Python 2.3. Here's the code I used:

   
   def enumerate(obj):
       for i, item in zip(range(len(obj)), obj):
           yield i, item 
   

All in all it only took around ten minutes to put the above together, after which the script worked just fine. It was interesting to see how our code had grown to rely on Python 2.3 features without us realising it.

Meru Updates Optimization Capabilities

Meru Updates Optimization Capabilities 07/13/2004 12:01 PM
Meru repackaged its software to allow users to easily configure their networks for a variety of situations: The software allows IT managers to select different configurations based on the type of use of the network, which consists of access points, a controller, and embedded software. "If you want to deploy voice, then you press optimize for voice so the controller will determine the best way for devices to connect and send packets and handoff is seamless," said Sarah Kim, senior marketing manager for Meru. "It's all the pieces of our technology that already existed but it's packaged in a way that the IT manager doesn't have to think about which set of parameters to turn on to get the best setting." Users can also choose to configure their networks for the best coverage and can opt for different configurations based on separate VLANs. Kim says that Meru's approach to network optimization is unique. WLAN switch providers tend to rely on power adjustment to optimize network performance, adjusting each access point's power output to achieve the best coverage. But Meru networks, which operate on a single channel, optimize on a per packet basis....

Comparing Python to Java

Comparing Python to Java 11/18/2002 12:57 PM
Java was designed to be an incremental step up from C++, with the rationale that for the price of a small bit of efficiency, you gained a huge amount in terms of simplicity, ease of development, maintainability, and portability. Python on the other hand "turns all the knobs to 10." It offers a beautifully simple, clean design that can result in programs that are extremely clear, easy to maintain and very quick to develop.

"tri" In my mind, what is true of Python holds true for PHP also. Furthermore I can train a C or Javascript programmer to code in proficiently PHP in 2 days. I cannot say the same for Python. Python enjoys a certain intellectual cachet among the digirati, but I think PHP is the better language, especially when PHP's support for threads and unicode is fixed.

Comparing C, C++, Java, Perl, Python,
Rexx, and TCL (pdf) 12/22/2002 11:37 AM
Google HTML version. The key conclusions of the research paper are

- Designing and writing the program in Perl, Python, Rexx, or Tcl takes no more than half as much time as writing it in C, C++, or Java and the resulting program is only half as long.

– No unambiguous differences in program reliability between the language groups were observed.

– The typical memory consumption of a script program is about twice that of a C or C++ program. For Java it is another factor of two higher.

– For the initialization phase of the phonecode program (reading the 1 MB dictionary file and creating the 70kentry internal data structure), the C and C++ programs have a strong run time advantage of about factor 3 to 4 compared to Java and about 5 to 10 compared to the script languages.

– For the main phase of the phonecode program (search through the internal data structure), the advantage in run time of C or C++ versus Java is only about factor 2 and the script programs even tend to be faster than the Java programs.

There is also an interesting debate at Lambda the Ultimate on my previous Developing Reliable Software with Scripting Languages essay.

Some people have got the impression the Developing Reliable Software essay advocates scripting languages as the best way to write software. That's simply silly - some things can only be done in a 3GL due to their better performance characteristics. All that was written was "This seems to be a pretty good justification for using scripting languages." Whether the justification fits the problem domain is up to you of course.

Also I am more interested in finding ways to make coding scripting languages more reliable, and not proving that they can be reliable. I am not interested in proving whether Python is more reliable than PHP or C# or vice versa. I just want our code to suck less.

Lastly the reason (which was never elaborated) why scripting is the now and future of computing is because the price/performance ratio of computers is still dramatically going down. The 68000 assembler that I wrote for the Macintosh in the 80's that I (hopefully) thought was highly tuned runs slower than the slowest Perl code I could write today. More and more problems over time have become amenable to the use of specialised domain specific scripting languages. One non-PHP example being the numerical processing now done using P ython and MatLab.

Another look at PHP and Python

Another look at PHP and Python 02/10/2004 02:46 AM
Postscript: Some people have got the impression from this article that I am moving away from PHP. That is far from the truth. I will continue to use PHP extensively today, tomorrow and for the forseeable future.

I find Python harder than PHP.

It could be because we are programming multi-threaded networked servers in Python, and that could be inherently harder than coding dynamic web-sites. Another reason could be lack of familiarity with Python. For example, I couldn't find the equivalent of htmlspecialchars and other functions, so i had to roll my own.

Despite all these issues, we are continuing to develop this in Python because (AFAIK) PHP does not have stable networking frameworks.

So what do I like about Python?

- Neat Syntax

The use of indentation for compound statements discourages deep nesting, and thus more modular code.

- More Safety Checks

In PHP, when you search using a regular expression, an associative array is returned. In Python, a typed object, "match" is returned when a regular expression search is performed, and not a generic dictionary. You cannot perform arithmetic on strings, an explicit cast is required; neither can you concatenate numbers with strings, explicit typecasts are needed.

- Supports Multi-Threaded Apps

There exists a global lock in Python that prevents multi-threading from working effectively on multiple processors - nevertheless Python has reasonable thread support and allows me to develop reasonably responsive servers.

- Python's Compiler is Standard

Python has a standard compiler and byte-code format. There is no such standard in the PHP world, and most ISP's don't support Zend or Turck MMCache encoded PHP. Better still, a debugger is included in the package too.

- Python Fully Supports Unicode

Python 2.0 and later has full support for unicode. For example to convert big5 to unicode is the simple:

    unicode_str = unicode(tw_chinese_string, 'big5')

In contrast, see how complicated it is to perform double-byte to unicode conversions in PHP (see User Notes).

The only issue i had with the unicode support is that it doesn't come with a complete set of double-byte decoders (eg. big5, gb). After a 20 minute google search, i found this set of python cjk decoders.

And what I dislike about Python

- Python Is Not Rapid Enough?

I think that PHP is a better tool for rapid application development, especially for web-sites. Minor type issues are handled for you transparently in PHP. In Python, once a variable is set, stricter type-checking is performed on most operations.

So you can argue that Python is safer. But PHP coding is definitely more rapid.

Another thing i dislike is that Python's import/load facility does not check .py file modification dates. If i modify a .py file, Python's run-time environment will not recompile it until i restart Python, or perform a reload manually from the command-line interpreter.

- Database Access

Python does not have official database drivers, and you have to select and download these drivers yourself. It's easy to get it wrong. For example, only after coding the adodb_odbc module using PythonWin odbc extension did i realize how awful PythonWin odbc was. I then found the mxODBC extension - unfortunately the mxODBC requires commercial licensing ($75 per CPU).

- Python is Not That Popular

Popularity is relative. There are lots of Python programmers - but there are perhaps 3 times more PHP programmers than Python ones. In Malaysia, the ratio of PHP to Python programmers is probably much worse (10:1?). And there are many training centers offering PHP courses. AFAIK, there are no centers in Malaysia offering Python training. A quick search in monster.com reveals the following (numbers might change over time):

PHP: 131 jobs
