First off, I hate flash. I use linux, and I have a netbook; I know very well how bad it can suck. For reasons beyond my comprehension, flash audio just breaks occasionally on me, including in AIR. On top of that, I have done a lot more web app development in javascript in an attempt to push browsers to their limits than I ever have flash. Aside from Sound Manager 2 (which doesn’t really count), I think the last time I did everything in flash was flash 7, so aside from some side knowledge, I know very little about flash. I really hope HTML5 is successful, but I don’t think it is a direct replacement for flash, no matter how much Steve Jobs bullshits. Here’s why:
Content Control
In the mad rush to move any web video over to flash, a serious point has been overlooked. Youtube may be able to set up backends for HTML5 video formats, but can Hulu? It is possible to save hulu apparently, probably though some strange use of rtmpdump, but from what I could see, those methods were convoluted at best. The question comes down to how something like Hulu, which must have ads on each video to survive, use something other than flash. I know from experience that ad block can stop the streaming of hulu ads, but hulu forces a longer black screen on you otherwise. I haven’t looked into the specifics of what goes on in the whole process, but it is safe to say that it is easier to restrict how content is handled on flash than the standard browser environment. The problem comes down to this: if uncompiled code is sent to clients, the client has the final control on how content is rendered. I wrote up a now broken approach to eliminating some facebook ads with simple css in firefox a while ago, but such approaches have only become more widespread. Site owners are starting to take notice of things like ad block, and some take serious offense. Facebook went as far to send a C&D to a firefox extension that modifies facebook rendering, of course they are pretty evil at this point (I am thinking of deleting my account, but that is a different story). I predict that in the near future, the question of how clients are allowed to modify the rendering of content will become a central issue to many web apps. The simple truth is that a compiled flash swf provides better code security than javascript obfuscation by several magnitude. Both on the front of audio and video and on just general content, flash provides content control that a browser just can’t match.
Standards are Slow to Adapt
If you have been following any of the debate over H.264 vs. Ogg Theora (better format vs. open), something will be apparent: content hosters have a bad deal. Which standard will prevail (probably H.264)? Is it worth doubling the number of videos to accommodate firefox? The questions go on. When flash introduced video, it was simply a matter of “run this version” on all platforms. The thing with browsers is that they are big projects. Chrome, which doesn’t even have the task of maintaining a full rendering engine, suffers from problems already as a result of being too big. I submitted a bug to Chromuim about 6 months ago for an SVG issue in the developer tools; I submitted the same bug to firebug first, and what I have seen says a lot about chromium. The firebug issue was tagged (for triage) on the same day I submitted it, and the fix was in a beta 4 months later. It took 3 months for chromium to do what it took a day for firebug to do (look at it), and all I have seen in about 6 months is a couple extra tags, and a few irrelevant comments. Mozilla is quicker with firefox bugs, but it is also safe to say that chromium has focused more on performance. These stats don’t even consider the number of developers on each, many of which professionally work on firefox and chromium, which can’t be said for firebug. I am not trying to raise questions in how open source development goes, but once HTML5 features lose focus, what will happen with bugs? What will happen when a better video standard exists? You can’t just fix standards; that’s why javascript and css are what they are. There is something to be said for keeping stuff in third party apps.
Maturity
Flash games have a special place. Traditional games don’t fill that niche; mobile games can’t fill that void; the truth is that it will take a while for javascript + canvas to substitute. It is a new technology, and one with interesting potential, but it is new, not mature. You can’t expect normal flash game developers to all of a sudden start writing stuff for the pure browser, especially when it gets harder, not easier. That doesn’t even consider SVG+javascript, which is actually a more near equivalent of flash, and even as that is more widely deployed, I will just say that it is even farther from being in a real production state. I wrote a web app on it, and I encountered, and still encounter, all sorts of weird browser bugs. To keep it short, it isn’t better to develop on an immature standard on 5 different platforms on 3+ different OSs than flash.
Conclusion
I think there are a lot of pros and cons in both directions of Flash vs. HTML5, and I hope and think that HTML5 will take over many of the uses of flash now. I think my defense of flash is rather incomplete, and my love of the browser environment is hardly expressed. Regardless, java, flash, or other plugins have served as the innovators of new approaches for a long while, and there is something to that. I hope third party methods don’t disappear, as I think the web ecosystem will suffer as a result.
I realize this post was mostly a rant, so if you have anything to add, please leave it as a comment, or send something to me.
Posted by knorby on April 1, 2010 under IM, google, internet, javascript |
A friend of mine was complaining about Empathy today, an IM client I have never much cared for. I have serious problems with gaim/pidgin too, and really, most of the reasons are the same. Of all IM clients I have used, I have been most satisfied with gmail; here’s why.
Great Chat History
Essentially any IM client at this point has chat history, but I really started using it once I started using gtalk. Why? I can search it easily, and it isn’t local to the machine I use it on; same main reasons I like gmail. It does mean that the FBI could get my chat records, but I am not too worried about that.
Reasonable Multi-client Handling
Part of using a standard chat client is having it start up after login, which usually leads to multiple logins if you use several computers, or leave one on and logged in. Pidgin or something will usually have a login per instance of the client, which really doesn’t lead to the desired behavior anywhere. With XMPP, you usually get a message everywhere on the first message, after which messages are only sent to the chosen client. Gtalk seems to only use one login, and handle a multi-client situation somewhere between broadcast and interface restriction. The instance of gmail with the most recent activity is notified with the alert, and the chat window appears in full, with the red alert color. On other clients, the window appears minimized and alerted, or not at all depending on several factors related to recent activity and what was already open. It works well. Android has its own model, but that is a different situation. It works really well. As an added bonus to this approach, status messages propagate well between clients, including to android.
Nice Balance Between Notification and Quietness
Most clients seem to work in one of two modes. Yell and scream activity, or say nothing. Aside from the ding, I think gmail is closer to the silent. If you are in gmail, you know when you get a message, and if you are in your browser, you probably notice the tab, but otherwise, it is ignorable. Most clients default to playing a loud sound a lot, and bringing up the window, in addition to more silent types of alert. If I am trying to do work, this is really, really annoying. You can usually reconfigure the client to be a little more silent, but it never works just right. I check gmail a lot anyway, so it ends up working pretty well.
Reasonable Away Message Handling
Since most people check gmail frequently, especially when not focused on something else, the away timeout tends to work pretty well. Watching a co-worker of mine, the timeout is usually accurate to about 5-10 minutes. The behavior on other clients seems to be either nothing or constant switching; plus you can get annoying status change messages!
No Setup
I don’t have to install or configure anything. I just use gmail. This is one of the more obvious reasons, but it comes in handy a lot. I just need gmail open, which I usually do.
I assume I am not really documenting anything new or interesting here for most people. My point is more that gmail or the likes of meebo are in many ways preferable to a more traditional app. Really, there is no reason a web app should be more usable than a traditional gui, but I find it is often the case. Many people use gmail for email now, but IM, especially among some techies, is only seen as a fallback, especially on the web. I believe that is simply not the case.
tl;dr gtalk in gmail is my favorite IM client

I started writing this post while Google Wave was still pretty new, but it has been out for a while and half forgotten. It is still in closed preview, but it shouldn’t be hard to find an invite if you want to check it out. As I mentioned in my last post on wave, I wrote a quick fortune bot for wave. The bot got a decent bit of use at first, as many people played around, but now use has dropped to almost nothing. Based on my own use, I figured early on that most of the use was from 1 or 2 real people interacting with a bunch of bots. I tested and confirmed that with the data google records by default.
Google App Engine, on which all bots must be hosted, by defaults logs any request and any error. A bot can register a number of different events, which will trigger a request to the bot. In the request, the state of the wave is contained in a json format. The log files can easily be downloaded, and the json easily parsed. From that, you see everything. You see the addresses of everyone, you see what has been entered, even if it doesn’t relate to the events of the bot. As far as I am aware, no TOS or privacy agreement exists that covers the use of this data, and even if it were, the most nefarious uses still would be silent.
By putting data on any web app, you put yourself up to the same risks and invasions. The google ads in gmail are targeted at you for a reason after all. If you are using gmail though, it is a safe belief that google will be the only one other than you to see your data. A bot could be maintained by anyone. Facebook apps are a decent comparison. I have looked at the API a couple times, but my understanding is even with the permissions a user can grant or deny, apps get to see a lot. A fair bit of criticism has been made of this platform, but it is very safe to say the privacy structure in place on bots is much worse. Aside from the lack of permission controls, would you use something like facebook apps on your e-mail or google docs (to the extent that makes sense…)? I hope not.
A wave user has a somewhat unique problem here. If a bot provides a useful service to a particular use, and the wave for this use is private, should you use it? That isn’t a question anyone should have to ask. The question of “put this data in this web app or not” is one thing, but you shouldn’t have to worry about using a pivot tables tool on an online spreadsheet, which is essentially what is going on with bots here. There isn’t really way to distinguish what is a good bot vs. a bad one either. If I wanted to snoop on people on wave, I would write a useful bot, and no one, google included, would be the wiser to what I was doing with the collected data.
I don’t think there is an easy way to fix bots as they are. Anonymous search results aren’t really that anonymous, and I would guess wave data would be much worse. The problem isn’t that App Engine logs requests; the problem is what wave sends. If you consider the data in a wave in anyway private, I would recommend against using bots.

Silly:
- fortune/doit – Implemented. See Wave Fortune. You can use it be adding wavefortune@appspot.com to your contacts. I mostly made this bot to satisfy my fortune lust, and to get more familiar with app engine and the wave bot api.
- wompus/adventure – Not sure I am actually going to do this one. If I do, it will be the wompus. Basically, the problem to solve is effectively storing state for such games. Wompus is tiny, and the games are short, so it wouldn’t take much thinking. Adeventure/zork would require a lot more work, and I honestly don’t care that much.
Tools:
- logging interface – It occurs to me that wave might work great in a situation where I think e-mail falls short now: data/msg dumps. I see this sort of thing at my jobs a lot. I get a log messages I generally don’t care about, and I filter them out, and as a result I sometimes miss something. A similar case is something like a bug tracker, where so many replies can be generated that the thread is easy to ignore. Centralization would help a lot I think, but again, I am not sure I care.
- RPN calculator - Nothing really to explain here. Could do save the calculator’s state in past blips, and make them editable. The end result would be a collaborative calculator of sorts. Could be interesting.
- something with jMol – Not too much thought here. When I was a student in the Computational Material Science group at ORNL, I ended up playing with jMol a bit from javascript. Some sort of gadget/bot combo could do some interesting stuff, but again, I don’t care.
I will post more about my thoughts on wave later on, as I have many mixed thoughts on it. Google has a lot to do, both on wave itself and extensions that they should provide. I am hesitant to work on large projects, as I don’t want to have google copy my work, or experience some odd situation with app engine. I don’t think anyone, google included, has any remote idea of what to expect from wave yet.

After reading the comments on a story on reddit on IQs, I became curious about how IQs are reported on the internet. A few people were saying that when they see someone mention their IQ on the internet, it is usually above 130. The explanations given were along the lines of people lying, biased online tests, and segmentation in where people browse. I was curious what sort of frequencies the different IQs are mentioned, so I wrote up a little python to get the google search results for IQs 50-199 (I would have included lower values after seeing the result, but I choose to go the scraping route rather than gdata, which ends up getting you blocked by google, something I didn’t know). I ran the number with the word “iq”; I think there may be better queries, but simple seemed good enough. Here are the results, plotted with matplotlib:
I found these kind of surprising. Most of the result counts were around 6 million, but there were a few sharp drops. I was especially surprised by 100 and 130, since, if memory serves, 100 is the 50th-percentile for IQs and 130 is the 99th; I would expect a greater count on these two, since more sites would include those numbers while explaining the scale; instead, there are large drops. Weird. I don’t think there is any connection between these results and anything proposed on reddit either.

Google Street View Map of Hyde Park. The streets without highlighting cannot be viewed.
I noticed recently that many of the streets in Hyde Park lost Google Street View, notably where my current apartment is. I also noticed that many of the streets had darkened. Is it really necessarily to remove the images? There used to be pictures taken inside the quads as well, which are now gone; I thought those might have been removed by request of the university, but I don’t really get why they removed the other ones. If they wanted to update them, fine, but there is no reason to remove images. I suppose it is a free service, so I have no right to complain, but I just think it is screwy when I can see my home in Oak Ridge, but not in Chicago. I did some quick googling, but nothing came up. Any ideas?

It’s true! Borja wrote up a summary of the GSoC lightening talk event, including pictures. If you don’t know what I look like, I am in both the GSoC student one and the ACM officer one. I really wish I got a haircut before this thing….
Borja linked to our website, which hopefully won’t get too much traffic. It is currently at 359 days of uptime, and I have shooting for a year of uptime before upgrading to the latest and greatest version of OpenBSD.
Posted by knorby on May 24, 2008 under ACM, Chicago, GSoC, Python, globus, google, personal, uchicago |
The ACM (just Borja really) organized a trip to Google Chicago, where all of the Google Summer of Code students who were accepted from UChicago (and in the US) gave lightening talks on our projects, which included me. The other GSoC students were Marcus Westin, Jordon Lewis, and Nick Edds. I put up my talk, as well as a more general page for my project on my CS site. Marcus and I both have projects with the Globus Alliance, so I was quite happy that he went before me, as I didn’t have to explain what Globus is. My project is fairly straight foreword to explain and I still don’t know the Globus Toolkit (GT) that well, so I couldn’t answer too many questions, and I ended up going under in time. Everyone seemed most interested in Nick’s project, since it is on the 2to3 tool in python, and a decent amount of the audience used Python, some with a great deal of dedication (it was at Google after all). I am pretty excited to see how Nick’s project turns out; we both went to the talk that his mentor, Collin Winter, gave at PyCon on the tool and the issues that Nick is working to fix.
The Chicago office’s engineering crew is dominated by subversion developers (in the small selection of software I like), but most of the presentations were about most unrelated projects. Ben Collins-Sussman discussed a VM for interactive fiction games like zork (I’ll still play my zork on the SDF TWENEX Machine; the version of zork installed is from 1981!). Karl Fogel, not a current Google developer, but subversion developer and good friend of the other googlers, gave a talk on script he wrote to help track patches from non-core developers based on logs. He put up some stats on the differences between subversion and GNU Emacs as projects; it further straightened my reasoning for using XEmacs. I went to a Russian choir concert the night before, as I had to go to a concert from a genre I don’t have any familiarity with, which he apparently was in; what a small world I live in. Brian Fitzpatrick gave a shortened version of the keynote he have at PyCon on balancing functional complexity with usability in software. Like all the other talks I have heard him give, it was an excellent talk; he has one of the best uses of slide shows I have seen, and I always end up thinking about the talks much later. There was also a talk from a developer for Blogger (he said he was now on feedburner); I would give his name, but I can’t remember it at the moment. I talked to him for a bit; I think my social awkwardness was in full swing at the time. I asked him about something I read on Valleywag about Google adding some preference search rankings with Blogger (I can’t find the post at the moment; I will link to it if I do); as I am sure is the case, he said that Google does no such evil. He also mentioned that Google crawls its own site with the same bot, which makes sense, but I hadn’t thought about it before. I wish I knew Blogger better, as I used it once for something else and had a couple thoughts about its workings.
It was a fairly awesome evening. I was very sleep deprived after one of my harder weeks here, so I was defintely in a strange state for the entirity of the thing. My thanks and appretiation go out to Borja and Google for this event. Apparently, my glorious face might end up on the GSoC blog or the Google open source blog.
