I see this kind of thing (on a variety of subjects) a fair amount:
Just some thoughts about BOSS. I find it useful but can't find further tutorials other than VW manual.
There are the docs, of course. However, I've also categorized some of my posts here, and the Smalltalk Daily screencasts are all organized here. There's a lot of information available.
Sportswriter Joe Sheehan introduces a column on pitching in modern baseball this way:
You can’t open a newspaper, a magazine or a browser without reading a complaint about starting pitchers. Complete games are at a historic low, the quality-start statistic has purists up in arms and the idea of pitch counts sends many people into convulsions.
I've wondered about the tyranny of pitch counts and the lack of complete games myself - but Sheehan explains that pitching isn't the same as it used to be:
Consider the change that has occurred since the start of Blyleven’s career. In 1970, when he made his debut with the Minnesota Twins, the American League’s second basemen had a slugging percentage of .332; the catchers .391; the shortstops .347. The league averages at those spots last year were .395, .417 and .412.
As much as I hate the designated hitter rule, it's more than that, and the problem exists in the National League as well. The reality is, there are simply more good hitters out there, and the lower mound (dating from 1969) has made it even more difficult. I don't buy the argument that there are more teams, so good pitching is harder to come by - if that were true, the league would also be full of light hitting shortstops. I think Sheehan has it pegged.
MTA digs up some interesting coincidences between JL Kirk and Associates and a few defunct businesses with exactly the same business model, and exactly the same operating locations.
Hmm. I wonder if JL Kirk will get "bought out" and "replaced" with another recruiting firm with eery similarities soon?

For the last slot on Tuesday, Georg Heeg will be presenting a topic that was well received at the Cincom Smalltalk User's Conference last winter: Connecting SAP and Cincom Smalltalk:
SAP NetWeaver provides very productive Business Modeling Capabilities, if the business model in questions fits well into the standard SAP NetWeaver models. When it comes to business tasks outside these standard models the productivity falls way behind. In these white spaces Cincom Smalltalk plays a surprisingly strong role providing adaptable flexible solutions. In a second part the presentation demonstrates the connectivity and integration of Cincom Smalltalk in SAP NetWeaver.
See you in Toronto!

I guess if the win was at my back, this might make for a good day to hit a long tee shot - assuming I could keep my grip on the club:
Local weather on the radio said that the wind advisory is being upgraded at 11 - we could start seeing gusts over 60 mph. Yay.
Nick Carr is overly worried about Google:
But it's when you look beyond advertising, to the broader economic ecosystem that's coming to define the way traffic and money flow through the consumer internet, that the Google-DoubleClick deal becomes more interesting, and troublesome, from an antitrust perspective. Google is not only the dominant player in the ad-serving market (and would see its dominance expand greatly by adding DoubleClick's dominant banner-ad business), but is also the dominant player in the web searching market, controlling somewhere between 48% and 64% of that business (depending on whose data you believe). It has also, through its recent YouTube acquisition, seized a dominant share of the burgeoning market for the delivery of video online. Combined with Google Video, YouTube controls 55% of that market, according to Compete, while its nearest competitor, MySpace, holds just 15%. Google's dominance in all these areas, moreover, seems to be increasing, suggesting that all these markets may have winner-takes-all characteristics.
Here's another, simpler possibility for Nick: maybe they have better products and better marketing. I'll wait while Nick tries to wrap his head around that idea.
I'll have the daily screencast up later - I am waiting for some car repair work to get done while I'm at Starbucks, so I can't really record the audio. The screenshot portion is all set though; I'll have a brief segment up about using TriggerEvents later today.
I'd take James McGovern more seriously if he realized that it's spelled Smalltalk (lower case t). Perhaps he's just a simple EnterPrise ArchiTect though, and I should keep my expectations lower.
The PR work for the marketing department at Sony will never be done - not when they have to explain why Sony DVDs won't play in Sony DVD players:
In their zeal to make their DVD movies copyproof (yeah right) they have in fact made their latest releases unplayable on some DVD players, including my Sony DVP-CX995V DVD player. I recently rented “Stranger than Fiction” (2 copies) and “The Holiday” ( please no comments on my choice of movies) both by Sony Pictures. Both load up to the splash title screen and then load no further, then after about 60 secs the player turns itself off!
ALL my other DVD’s and new releases from other movie companies play perfectly
Looks like I won't be buying - or even renting - any Sony DVDs anytime soon - especially given this kind of "tech support":
Sony Tech: We know about this problem. Its our new copy protection that’s making these discs unplayable in some players including our own, we do not intend to change the copy protection. The only correction to this problem is a firmware update to your player. The electronics division know about this and should have given you this information.
Me: OK send me the firmware update.
Sony Tech: We do not have one as yet.
So here's a question for the bright guys at Sony: Will this even slow down the dedicated pirates - you know, the ones who rip off movies and sell knock-off DVDs on the street? Not one bit, no. Will it irritate the crap out of your paying customers who are buying your hardware and software, and then finding out that they don't work together? Furthermore, will their first thought be something like "gee, my Sony DVD player must be broken - better run down and buy a new (non-Sony) player"?
You just have to marvel at the thought process that brings this kind of thing to market.

For those attending the Beach Outings Club tomorrow there will be a raffle (determined by a 20-sided die) for free registration to the Smalltalk Solutions conference. I didn't say the show. I said the conference. This retails for ... a lot. It's thanks to show management at http://www.it360.ca
Since some of you don't live in The Annex in Toronto, if you want to be represented by proxy for this raffle, then send an email to dynamicword

However, given the weather in the northeastern US and Canada right now, I wouldn't dress for the beach :)

On today's Smalltalk Daily, we take a look at sending and receiving TriggerEvents. Today's screencast was a bit delayed - I had to spend part of my day at the mall waiting for my car, and most of the afternoon looking for a book my wife wanted to give as a gift.
Looks like internet radio - at least so far as major label music is concerned - is dead:
A panel of judges at the Copyright Royalty Board has denied a request from the NPR and a number of other webcasters to reconsider a March ruling that would force Internet radio services to pay crippling royalties. The panel's ruling reaffirmed the original CRB decision in every respect, with the exception of how the royalties will be calculated. Instead of charging a royalty for each time a song is heard by a listener online, Internet broadcasters will be able pay royalties based on average listening hours through the end of 2008.
The judges hearing the case had wax clogging their ears:
The judges were unmoved by the webcasters' arguments. "None of the moving parties have made a sufficient showing of new evidence or clear error or manifest injustice that would warrant rehearing," wrote the CRB in its decision. "To the contrary... most of the parties' arguments in support of a rehearing or reconsideration merely restate arguments that were made or evidence that was presented during the proceeding."
Umm, yeah - they said "this ruling will put us out of business". Which part of that was hard to understand? The net-net of this? No revenue stream for the labels from this direction, because the dollar signs are too big. That's probably what the music labels want, because they think they can cap off the net, and force things back to the business model they are familiar with. What it really means is that the major labels have just cordoned themselves off from the internet, and ensured that a new set of businesses will take over that space, charging reasonable amounts of money to air artists who won't be signing with the major labels.
For the final regular presentation on Tuesday at StS 2007, we have Michael Lucas-Smith talking about C connectivity:
Since C was first invented, other programming languages have found it necessary to interface to C libraries. Smalltalk is no different and yet after more than 27 years we're still struggling to adequately interface with it. Every Smalltalk implementation provides a mechanism for interfacing with C and they all have their quirks. We will discover how the different Smalltalk implementations try to solve the C interface conundrum and how other languages try to solve the same problem. We will explore the quirks and tricks of interfacing with C from VisualWorks by examples collected over the last 6 years pf interfacing with various open source C libraries. We will also delve in to the many tips and tricks that have been learned over the years when interfacing Smalltalk with C across different Smalltalk implementations. Other programming interfaces to other languages such as COM and Cincoms .NET connect will be explored as well. We will also look at how Smalltalk can better interface with C in the coming years, and why it is still relevant in modern computing
See you in Toronto!

Bill Hibbs rounds up the aftershocks from the JL Kirk and Associates mess, and points out how eminently predictable it all was. From a quoted story by Brittney Gilbert:
I have never seen a move as ham-handed and wrong-headed as the one made by JL Kirk Associates and their attorney(s). I have sat back and watched in sheer amazement as this transparent and completely obvious attempt to bully a blogger has backfired a thousand times, over and over and over again. It's been fantastic and fascinating to watch.
There was nothing in Coble's account that even closely resembles libel or "false and defamatory statements." Not unless you think a negative film or restaurant review counts as the the same.
Pretty much says it all. Next time I do the presentation recorded here, I'll be using this mess as my primary example of what not to do.
PR Differently goes into detail on a PR misstep by Steve Rubel - yesterday, he twittered this:
PC Mag is another. I have a free sub but it goes in the trash
Yeah, there's a way to win friends and influence people :) You thought it was easy to lay eggs on a blog? Things like Twitter make it even easier for a passing thought to cause trouble. Today, Rubel did respond to the criticism.
On today's Smalltalk Daily, we go back to Seaside with the Employee List example. Over the next few days, we'll build up a master/detail application, as we did with the GUI builder.
Finally noticing that all the publicity surrounding this event was bad, JL Kirk contacted Katherine Coble's lawyer and told him that they did not want to litigate.
Note to the lawyers: contact your PR staff before you wave lawsuit threats.
I always thought this guy didn't get OOP, and this post just proves that point.
Tim Bray tells a story about a joke that went flat (the audience had no idea what Twitter was):
In March, I gave a keynote at Web Design World in San Francisco. Frankly, it did not go that well; in particular, the crowd didn’t laugh at my jokes. Here’s one of them, more or less: “Being a Web Guy at Sun is a little intimidating. At high level strategy meetings the Chip Guys talk about what they’ll be shipping in 2009, and both the OS Guys and Java Guys talk about things a year or two out. As for us Web Guys, well... three weeks ago, I didn’t know that Twitter would become the Hot New Thing.”
Going on, Tim asks the obvious question: if Twitter is experiencing massive scaling issues (tens of thousands of hits per second! at times), then how do we square that with the "no one has heard of it" problem?
I think what we have is a large niche of social software users. Periodically, I ask my daughter (age 13) or her friends about things I'm seeing or working with : Blogs, RSS, Twitter, social networks. The funny thing is, most of them are heavy users of IM, but very few of them have gotten past the "I've heard of that" stage with things like Xanga, MySpace, etc. Before I brought it up, none of them had even heard of Twitter (and they all declared it "stupid" upon seeing it).
The web, and social software in particular, allows for something unique: shared interests that extend far across geographic boundaries. So in a town of 100,000 people, it may well be the case that "no one" has heard of Twitter - but that lots and lots of like minded people across the planet (at least, in the connected parts of it) have. I don't know how big the net connected population is, but even a small fraction of it can add up to a fairly large number of people - especially when they all try to jam their way into the same doorway.
Update: Jon Udell adds some thoughts.
Second Update: "The Last Podcast" adds some further thoughts - this is probably a lot truer than many would like to believe:
As an aside: There seems to be this general idea that kids in college are at the forefront when it comes to technology. I say: BS. Most of my students can hardly get a photo off their digital camera. They don’t know how to use their computers beyond AIM and most don’t know how to even change the margins of a document in Word.
That would not surprise me a bit. I think us tech folks assume a wider usage of a lot of niche things. Most people are interested in utility, where we get interested because it's technically cool. Most people just want to use tools, not obsess over them.

The final event on Tuesday will be the Smalltalk Panel:
Anyone who is interested is welcome to attend and participate. Members from each of the STIC Board Member organizations will be available to talk to new members and those interested in find out more about STIC. The meeting will be moderated by Bob Nemec, the Executive Director of STIC.
Panel members are: Monty Williams from GemStone, Suzanne Fortman from Cincom, Ed Klimas from Instantiations and David Buck, an independent consultant.
A panel discussion on the issues of marketing Smalltalk to the decision makers, typically non-technical management that needs to balance the costs and benefits of selecting any development tool. Most Smalltalk advocacy material talks about the technical benefits: how you can build complex applications with less effort if everything is an object. But how do we prove this? How do convince a typically risk-averse manager that using a niche language like Smalltalk can provide competitive advantages that out-weigh the risks

Instantiations has announced an update to VA Smalltalk. You can get details over here, in the readme for the release.
On today's Smalltalk Daily, I clean up yesterday's example so as to be more conformant with web and Seaside standards.
Via Doc Searls, I found this from David Byrne (Talking Heads) - which pretty much explodes the notion that the major labels are killing internet radio "for the artists". This is about one thing, and one thing only: the preservation of a business model to which the big record labels have become accustomed. Our wishes as consumers, or the wishes of the artists who actually produce the music are entirely secondary (insofar as they come up at all).
Doc has some ideas for how we might deal with all this; follow the first link for more on that.
CNET reports that Sony is paying for the PS3 the hard way: layoffs. The root of the problem? The PS3 is way, way above the "what the heck" price point, while the Wii hits it. Meanwhile, Sony has to fight with the bottomless pit of money from Microsoft (XBox 360) - because the XBox and the PS3 are going after the same gaming demographic. Meanwhile, Nintendo has the casual gamer space all to itself, and a price point that says "buy me now!"
Nick Carr notes that the kinds of periodic spikes in traffic that companies sustain (Intuit at Tax time, retailers near Christmas, flower vendors near Valentine's day, etc) result in an over-buy of capacity for most of the year's traffic load:
To run its business with private, dedicated servers, Intuit needs to build its data centers with the capacity necessary to handle the extreme spike in traffic - the peak load - that comes on tax-filing day. Thge vast majority of that installed capacity will go unused most of the time. Multiply that low capacity-utilization rate across thousands of companies, and you get a good sense of the wastefulness inherent in the proprietary model of computing, particularly as companies have to handle rapidly fluctuating web traffic. The only way to do cloud computing efficiently is to share the cloud - to establish a broad, multitenant grid (or a number of them) that balances the loads of many different companies. Otherwise, it'll be one cloudburst after another, and a whole lot of underutilized capital assets.
I wonder if Amazon has sales staff over at Intuit right now, pitching EC2? It looks to me like Amazon may have been crazy like a Fox with that initiative - because it's exactly the kind of "utility" grid that Carr is on about.
Peter Fisk has some thoughts on WPF/Silverlight - and in the process, explains why he's now building his Smalltalk implementation on an Adobe base instead of a .NET one.
Obvious Corp. has spun Twitter out:
The time has come for Twitter to make that leap. We’re happy to announce that Twitter is graduating from the home of Obvious and becoming its own company -- appropriately named, Twitter, Inc.
I suspect that we'll start to see some kind of monetization plan coming out with that - and I bet it will be oriented more towards phones/mobile devices than the web.
First thing Wednesday morning at StS 2007, Bert Freudenberg is going to talk to us about EToys on the OLPC:
Smalltalk has been used to work with children since its beginnings in PARC's Learning Research Group. Now it takes part in what might be the largest educational project ever: "One Laptop Per Child" aims to enable education for children in the developing world. Etoys, a tile based authoring environment written on top of Squeak, is one of the central software components in OLPC's "$100-laptop". The talk gives a technical background on Etoys as it is implemented on the laptop currently, and highlights related research projects such as Tweak (which takes many "enduser" ideas to the system level) and TinLizzie WysiWiki (extending Etoys into a collaborative environment using Croquet and Web technology).
See you in Toronto!
Over the last couple of days I've started seeing something interesting in Twitter: trolls, likely automated ones. I've gotten a few "friend" requests from users with enormous numbers of friends and followers - but their stream of "messages" is just utter crap - things like "now smoking crack", for instance.
Looking at the signup and API for Twitter, I don't think it would be very hard for a jerk with time on his hands to create a "friend-bot". Just pick a well known user, scan their friend list (available on their Twitter page), and start friending. As you get new ones, add to your list, repeat.
You don't have to accept these requests, but they end up as "followers" no matter what you do.
Rogers Cadenhead notes that the tech tools we love (and rave about in our blogs, podcasts, etc) are just that - tools. Like any other tools - cars, guns, knives, what have you - they can be turned to acts of good or evil.
Update: Dave Winer makes an excellent point - the bad actors will keep pushing the envelope on this stuff:
What's next? Isn't it obvious -- the latest and greatest stuff, Ustream, Twitter and mass murder. When you see a suicide bomber with a camera strapped to his or her head, you'll know that the bad has caught up with the good.
Today, justin.tv. Tomorrow, exploding heads.
Joel on Software talks about search in Outlook, and how MS went out of their way to kill a useful third part app:
The only possible explanation is that someone on the Outlook team is getting paid a bonus for convincing people to switch to Gmail.
The story has a happy ending. Last week Microsoft released a patch for Outlook 2007 which fixed the problem for me (I have a lot of big PST files, which, I'm told, is why search was so slow for me). Now I can search old email quickly enough that I don't forget what I was searching for by the time the results come up. It's not quite as fast as Lookout used to be, but it's a big improvement and makes Outlook less of a downgrade.
I'd call that pretty faint praise. Here's a question: why did MS care about Lookout? What possibly reason did they have for being so concerned? If a third party improves your product (thus improving its overall marketability), what's the downside?
Never mind the layoffs - Sony must have extra money to throw around. First, they implement a new copy protection scheme on new DVDs that breaks existing DVD players (including their own). Next, having noticed that customers are less than pleased by this, they issue a recall.
The net result: Bad PR for Sony, possibly lost sales, and an unnecessary expenditure of cash to fix the problem. Is someone paying Sony execs to produce own goals?
Scoble explains why you shouldn't use partial text feeds:
Out of, say, 1,000 people who are on the Internet, only a small percentage read a lot of feeds. Let’s say it’s 10%. That means only 100 out of any 1,000 people will read feeds and of those 100 people only a small fraction will bother with ZDNet’s feeds.
The thing that partial texters are forgetting is that the other 900 people will find out about you from an influencer. Someone who will tell them. So, your traffic growth will be far slower if you only offer partial text feeds. Many of my friends who are journalists or bloggers just won’t deal with partial text feeds anymore.
Here's how people who want to pitch full feeds should go about it - describe them as a loss leader. Sure, the small percentage of people who find you via RSS/Atom won't see your ads. However, the people who follow their links will. It's no different than offering a sale on some small item in order to suck people into your store - you'll make up the loss on all the other sales. With syndication, it's even better, because - as Scoble points out - there aren't that many people (relative to the whole audience) reading you that way. They happen to disproportionately be influencers though.
Looking for a Seaside/DB combination? Then this Wednesday morning StS2007 session is for you: Gemstone, Linux, Apache, Seaside:
The Seaside framework provides a layered set of abstractions over HTTP and HTML that can be used for developing sophisticated web applications in Smalltalk. Seaside was developed in Squeak and ports are available for VisualWorks and for Dolphin. While the Seaside framework elegantly addresses HTML generation and application flow-of-control issues, it still leaves a few challenges for the developer - including persistence and multi-user coorrdination. In this seminar we will demonstrate a port of Seaside to a new dialect: GemStone/S. As a multi-user, persistent Smalltalk implementation that has no native user interface, GemStone/S provides an excellent environment for serving HTML

I'm currently reading a very interesting book that covers the end of the Stuart Dynasty - "The Glorious Revolution" in particular: "Ungrateful Daughters: The Stuart Princesses Who Stole Their Father's Crown".

Don't expect stellar displays of logic when old, tired, and scared businesses try to use any trick they can find to attack an upstart. For instance, take a look at the National Association of Broadcaster's current line against the XM/Sirius merger:
Problem is, the only colorable argument against the merger is that it would create a monopoly for satellite radio. XM and Sirius cleverly (and probably accurately) headed that objection off by noting that satellite radio competes with a variety of technologies for the listener's ear. This put the NAB in an awkward position. The lobby would have to argue that despite its 15-year effort to derail satellite radio, satellite radio was not a competitor. Of course, the harder the NAB fights and the more money the NAB spends to promote this message, the clearer it becomes that the NAB fears the competition posed by an XM-Sirius alliance. In effect, the more the NAB fights the merger, the more it undermines its own argument against it.
I'm sure they'll think of something. In the meantime, I expect an uptick in subscriptions once this merger does go through.
Unless a catastrophe is reported this weekend, we are finally ready to ship ObjectStudio 7.1.2, VisualWorks 7.5, and the beta release of ObjectStudio 8. We apologize for the lateness of the release - we are looking to optimize some of our processes in order to not have a repeat :)
In the meantime, there are a few issues that people should be aware of:
The good news: we'll have non-commercial CDs at Smalltalk Solutions to hand out. So: See you in Toronto!

More talk about the full vs. partial feed thing, with some evidence from FeedBurner tossed in:
As people subscribe to feeds, they subscribe to more feeds. And that means they’re consuming more content, which means that each click out of the feed reader is taking the reader away from more content. In other words, feed reading is consumption-oriented, not transactionally focused. We’ve seen no evidence that excerpts on their own drive higher clickthroughs.
Which is why the author - like me - recommends full feeds. The only counter he lists is weak:
The main issue I see with publishing a full feed is the risk of your content being used by scraper sites. For those of you unfamiliar with scraper sites their sole purpose is to generate income through advertising by republishing content stolen from RSS feeds.
Scraping HTML is really not that difficult - whether you want to accept it or not, you crossed that particular bridge as soon as you offered a website...
This week's "Industry Misinterpretations" is in the can - we discussed some common "Smalltalk Myths". While doing so, a few references came up that ought to be linked to.

Wednesday morning at StS 2007 we have another interesting talk: validation with SUnit:
SUnit Validation was originally conceived by Andres Valloud as a framework for instantaneous feedback on data consistency in the GUI. The framework brilliantly solves the classical problem of handling user inputs in the event that they do not make sense in the model. As envisioned initially, validators factor out repetitive checks that are usually found in the presentation layer. However, the experience has shown that validators are extremely helpful in identifying and solving a wide range of problems. The talk will summarize the experience of introducing heavy validations in a simulation system that has been successful for more than ten years in the Petroleum Industry. That includes new uses of the framework for the GUI, and applications to other areas as model diagnosis, validation of data imported from (and linked to) external sources, version upgrading, naming services, object deletion, SUnit testing, debugging support and automatic source code QA.

I think Heinlein was right: TANSTAAFL. Look at municipal WiFi in Boston - they've banned that hotbed of danger, BoingBoing.
Sam Gentile has had it with Vista for the moment - but two of his complaints caught my eye:
That reminded me of something Dvorak has been saying about Vista for awhile now - that Vista really needs one of the new hybrid drives (they have embedded flash drives to allow onboard cache operations). Now, I haven't so much as looked at Vista, so I don't really know - but it makes me wonder whether Microsoft might have jumped ahead of the required technology infrastructure by a year or two. The fact that Dell is back to offering XP as an option doesn't bode well, either.

I had an enjoyable afternoon and early evening playing board games. Mid afternoon, I took my daughter over to a friend's house, and 3 of us sat down to play Caylus. It's a good game, and I was trying something different - instead f running up the building track, I went down the resources track. Worked out pretty well; I won going away.
We broke for dinner, my wife joined us, and we played a game of Puerto Rico. My wife won that game - it was close, but I needed one more round of shipping than I planned for. After that, my daughter's outing was over and it was time to head home. A nice way to spend a day though!
On Wednesday afternoon at StS 2007, Panu Viljamaa will be talking about Method Testing:
A new framework for unit-testing that takes advantage of Smalltalk's "live environment" is presented. The approach, called Method Tests, relies on the ease of plugging into the Smalltalk compiler from within the IDE. Unit-tests associated with a method are then run automatically whenever you save a method. Every method becomes a "unit" of its own, with its own tests which at the same time express the method's "contract".This provides benefits not unlike type-checking, but for dynamic languages. The Method Tests framework makes writing tests easy, by providing a simple four-method API based on Smalltalk's block closures. The implementation and issues relating to testing dependent packages and subclasses are explored, and solutions provided.
See you in Toronto!

Georg Heeg is the new director of STIC - I'm sure he'd love to hear your suggestions - or better still, an offer to help out.
We've pushed Cincom Smalltalk Spring 2007 out the door, just in time for Smalltalk Solutions. We'll have CDs to hand out there, and - as soon as the files are updated to the proper locations - we'll have them ready for download.

Now this is what I've been waiting for (in addition to Stargate, which returned recently) - Heroes is back with new episodes to end the season. The DVR is primed and ready :)
I've just updated the NC download application - the login page is gone, replaced by a simple Registration page. Once you register, a cookie will be dropped on your system, and you'll be redirected to the download page if you visit again. So I apologize for the inconvenience of having to register again, but it's part of making the whole process simpler.

I wrote about the silliness of the way Vista handles Installers awhile ago; they run with admin rights. Now, it turns out that it's even stupider than I thought:
"If Vista sees that you have created a Microsoft Visual C++ project with install in the project name, then that .exe will automatically require Admin Rights to run. Create exactly the same project, but call it, say, Fred, and the problem disappears," he explained. "Vista's security isn't just concerned with what an .exe is doing to your PC, but what it's actually called."
I think I'll call that security via stupidity.
