  "Considered Harmful" Essays Considered Harmful
Because "considered harmful" essays are, by their nature, so incendiary, they are counter-productive both in terms of encouraging open and intelligent debate, and in gathering support for the view they promote.
Usually such "considered harmful" essays are intended to draw attention to a little-known subject about which the author is passionate, or to highlight what the author feels to be a poor decision by someone else.
The writing of a "considered harmful" essay often serves to inflame whatever debate is in progress, and thus makes it that much harder for a solution to be found through any means.

 jargon, node: considered harmful   (Site not responding. Last check: 2007-11-05)
considered harmful /adj./ Edsger W. Dijkstra's note in the March 1968 "Communications of the ACM", "Goto Statement Considered Harmful", fired the first salvo in the structured programming wars (text at http://www.acm.org/classics).
Amusingly, the ACM considered the resulting acrimony sufficiently harmful that it will (by policy) no longer print an article taking so assertive a position against a coding practice.
In the ensuing decades, a large number of both serious papers and parodies have borne titles of the form "X considered Y".

 Considered harmful - Wikipedia, the free encyclopedia
In computer science and related disciplines, "considered harmful" is a phrase popularly used in the titles of diatribes and other critical essays.
Frank Rubin published a criticism of Dijkstra's letter in the March 1987 Communications of the ACM titled "'GOTO Considered Harmful' Considered Harmful".

For that reason we should do (as wise programmers aware of our limitations) our utmost to shorten the conceptual gap between the static program and the dynamic process, to make the correspondence between the program (spread out in text space) and the process (spread out in time) as trivial as possible.
Let us now consider how we can characterize the progress of a process.
With the inclusion of procedures we can characterize the progress of the process via a sequence of textual indices, the length of this sequence being equal to the dynamic depth of procedure calling.

 GoTo considered Harmfull
Although the setting of the problem might seem somewhat academic at first, the author trusts that anyone familiar with the logical problems that arise in computer coupling will appreciate the significance of the fact that this problem indeed can be solved.
The Problem To begin, consider N computers, each engaged in a process which, for our aims, can be regarded as cyclic.
In each of the cycles a so-called "critical section" occurs and the computers have to be programmed in such a way that at any moment only one of these N cyclic processes is in its critical section.

 uiGarden.net - Weaving Usability and Cultures: Human-Centered Design Considered Harmful
Consider art, where much time is spent learning the vagaries of the media.
Consider the dynamic nature of applications, where any task requires a sequence of operations, and activities can be comprised of multiple, overlapping tasks.
Sometimes it is worthwhile to re-examine them, to consider the pros and cons and see whether they might be modified or even replaced.

 Use of NFS Considered Harmful   (Site not responding. Last check: 2007-11-05)
The idea is to avoid the overhead of putting a process into a suspended state until data is available, because the data is always either available or not.
Consider the performance implications of sharing even an extremely fast hard disk with hundreds of other users.
NFS is generally considered an easy means of solving data sharing problems because it is often already configured and installed.

 Csh Programming Considered Harmful   (Site not responding. Last check: 2007-11-05)
From: Tom Christiansen Newsgroups: comp.unix.shell, comp.unix.questions, comp.unix.programmer, comp.infosystems.www.authoring.cgi Subject: Csh Programming Considered Harmful Date: 6 Oct 1996 14:03:18 GMT Message-ID: <538e76$8uq$1@csnews.cs.colorado.edu> Archive-name: unix-faq/shell/csh-whynot Version: $Id: csh-faq,v 1.7 95/09/28 12:52:17 tchrist Exp Locker: tchrist $ The following periodic article answers in excruciating detail the frequently asked question "Why shouldn't I program in csh?".
Consider the common C construct: if (p andand p->member) Undefined variables are not fatal errors in the Bourne shell, so this issue does not arise there.
Consider this statement: exit (i) Of course, they really meant exit (1) or just exit 1 Either shell will complain about this.

 PKI considered harmful
Presumably the certificate is considered a gate-keeping operation to enter a user into the system, but the actual cryptographic effect of the certificate's signature from a certificate authority now seems lost.
Consider the policies of popular distributors such as browser manufacturers: the inclusion of a CA has (at least historically) been justified solely on the basis of the audit of the CA, even though the audit process would generally stress that the user herself should not accept an audit on face value.
It was also considered that if there were such enormous amounts of personal information, the certificate was no longer being used for just authenticating the person, but was, in fact, identifying the person (which is another way of viewing the significant privacy and liability issues).

 Considered Harmful — Peter Ahé's Weblog
The benefits should be clear and I like to think if Dijkstra had been consulted on generics he would have said: "not having generic types should be considered harmful".
Ken Arnold doesn't understand generics and thus he suggest that generics should be considered harmful.
We did consider a new addition to the language, statically type-safe arrays.

 Bandwagons Considered Harmful
Those advocating curricular change must articulate their educational goals fully and consider explicitly what effect on those goals they expect the change to have; they must not throw the baby out with the bathwater.
Changes in introductory curricula are made too often as a hasty attempt to jump on a current bandwagon, without thoughtful consideration of pedagogical goals and the value of the topics being supplanted.
But those promoting them must be prepared to consider and address the potential side effects and tradeoffs of their innovations.

 with Statement Considered Harmful » Yahoo! User Interface Blog
Thanks for publishing this useful piece of advice, as it should be known by all JS developers.
If you are referencing a global variable (or any variable not in the top scope, that is the target of the &#8220;with” statement), a deeper scope chain will take more time to do a lookup, and this is where performance degradation can be caused by the with statement.
However if we consider Douglas’s example, when JS machine encounters o.bing, it must first do a lookup in the current scope for “o” and then it must do a lookup in the o object for “bing”, so it must do two lookups.

 Weblogging Considered Harmful
Have any of these companies considered the possibility that if they showed some respect for the consumer, the consumer might show some respect for them? Instead, media corporations seem to be treating their customers with complete and utter contempt by basing their distribution systems on the idea that all of said customers are potential crooks.
The Register appears to be getting some grief over its new design, though not quite as negative as the response to Salon's recent redesign.
The few people to whom I've shown a new Considered Harmful design have been pretty positive about it, and this existing page is pretty bland, but I still worry.

 CVS Considered Harmful
Directories are a small issue, as -P mostly takes care of it, and moving files by adding it in its new place while removing it at the same time from the old is just as confusing (regarding logs and history) as systems that explicitly allow moving files, no less and no more.

 <FONT FACE> considered harmful
Time to consider a real character encoding, which will be able to carry your words in plain text, whatever the medium (mail, news, chat, etc.) HTML is about enriching text with hyperlinks and embellishments, but the underlying plain text should already have its proper meaning before HTML markup comes into play.
If you think you are doing some language community a service by making up fonts and using them as described above to publish on the Web, please think again.
Consider instead keeping your bytes, characters and glyphs as separate things:

 Dr. Dobb's | Java's <i>new</i> Considered Harmful | February 28, 2002
If you believe in classes — that is, you believe that it is conceptually clearer to distinguish between classes and objects — then prototypes are a bit unpalatable because they blur that distinction.
For instance, consider the server framework previously described, which creates a new connection object for each client.
In short, new should be considered harmful for the same reason that goto is considered harmful — although it is an indispensable low-level tool, it must be used with care or hidden behind abstractions.

 Sam Ruby: AJAX Considered Harmful
Adam: while I tend to side with Roy, for the moment, let’s go with your definition.  The problem with the current AJAX toolkits is that they don’t allow people to pick the verb, so without them realizing it, they are creating “bookmarkable” URIs for all operations, including unsafe ones.

 Overloading considered Harmful - Java Tutorials   (Site not responding. Last check: 2007-11-05)
There are several problems related to this, but first let's take another look on the small code example presented in a former edition of this newsletter in order to really get a feel for what it's like when methods being called are not independent of the reference types being used for the calls.
A minimal modification allows us to focus on the ugly side of overloading: The program still tells us which method gets actually called, but on top of that also delivers rather strong comments when overloading is caught to harm our ability to reason about the client code without knowing the server classes.
Basically, we have two fixed instances, which will play always the same roles: one serving as call target, the other serving as argument.

 Ken Arnold's Blog: Generics Considered Harmful
Sun better considers implementing generics at the VM level.
Now, consider that we are 10 months past 1.5.0-FCS, and the adoption of Java5 is still modest (at least in my POV).
I think it was worth the trouble, to take a type-theory-savvy bunch of programmers to design a generic standard library, given the million of people who will reuse their code.

There are a handful of incremental improvements to the full-sized iPod: Brighter screens, longer-lasting batteries, a $50 price drop, and a boost to 80GB in the higher-capacity model.
I'm still not clear on whether these are considered a new generation of iPods.
Nothing I'd go out of my way to upgrade, but if I had actually bought a new iPod a couple of weeks ago (instead of scraping in just under the 6-month warranty for a free replacement), I'd be kicking myself.

 Fabrizio Oddone - Exceptions Considered Not Harmful
Since I used the negated form, "Considered Harmful" Essays Considered Harmful by Eric A. Meyer should not apply.
Incidentally, somebody else already came up with Exceptions Not Considered Harmful so I had to use a slightly different title, not mentioning to write a rather more urbane rebuttal.
Most people who agree with me on this topic and have been reading Joel's articles since the inception of Joel On Software may be asking themselves why in the world a smart guy like him does not grok exceptions.

 Ajaxian » Javascript Associative Arrays considered harmful
You can’t really consider JavaScript objects as analogous to HashTables etc. because the keys may only be strings.
If you try and use Objects as keys then all Objects will map to the same value, since when you assign a non-string key JavaScript just calls toString on it, meaning all your keys will simply be stored as “[object Object]”.
Some might argue extending any of the built-in objects’ prototypes is bad form, but those people are wrong.

 Design Patterns Considered Harmful
Too much flexibility in a design can be harmful.
Practicing the forms correctly leads to insight into the techniques and gets the body used to moving in ways that hopefully make the person a better fighter.
However, when you find yourself in an actual fight to defend yourself from bodily harm, if you go into one of your forms you'll get your butt kicked.

 Default Instance Considered Harmful...?
We considered introducing a single instance/multi-instance mode switch into Windows Forms, but that would mean that changing the instancing mode of a form would cause drastic changes in the way the form was used in code.
Thus, it would be vital to choose up-front whether a form was going to be single instance or multi-instance, and woe be unto the developer who chose incorrectly.
The other major idea we considered was introducing some kind of configurable warning into the product that would allow people to turn the use of a default instance into a warning or error.
