In 2005 I obtained a job at a regional ILEC as a Data Operations Technician. As part of this job, I took over development of one of the tools we used to diagnose customer DSL connections. Problem was, this tool was written in PHP, a programming language I was, as yet, unfamiliar with.
At the same time, I was also looking for a web-based tool I could use to keep track of various tasks. While there were a few open-source tools I could use, none had the features I was looking for. So I decided to write one myself, and to write it in PHP so I could learn the language better. In the end, I'm glad I did as PHP has become indispensable for writing web-based tools.
The tool I wrote was a web-based todo manager called phpTodo. Since the alpha release in 2005, I have released 7 more versions. Work on phpTodo has ebbed and lowed with time, often interrupted by work and life in general. In fact, the last formal release was made almost 5 years ago, bringing the current version up to 0.8.1. In 2009, I found out that phpTodo was being packaged and released with Fedora as well.
I'm quite happy with the general feel of the new version I've been working on. While there is a good deal more code to be written, I'm confident there will be a code release soon enough.
I've been thinking a lot about the future of phpTodo and where I want to take it. When I originally started, I wrote the system such that I could see my todo list items via an RSS feed. At the time, I had a Blackberry phone and this worked brilliantly. Of course, this was purely a one-way feed with no way to update any todo items on the go. Since that time, I started working on a mobile view for the system, but stopped quickly after I realized how horrible working with WAP was. Fortunately, technology has progressed quickly since that time and WAP is no longer necessary. So, I'm considering working on a mobile version again.
A mobile version brings new challenges, however. It should be trivial to develop a mobile view that can be used while online, but my hope was to have an offline version as well that can be synchronized with the online version. One possibility is to develop an app that can be loaded onto a phone. That, of course, severely limits the platforms it can be run on. Another possibility is an HTML5 version, though that brings challenges of its own.
Another thought was to build a web service into phpTodo. The basic premise is an XML generator that, given a set of parameters, can supply an XML feed for external systems to use as input. And an XML parser that can receive data from external systems in order to update phpTodo data. I believe this can be used as the interface for the mobile view.
A web service can also be used to power another idea I had. I stumbled across the website of Brett Terpstra a while back and found a treasure trove of interesting ideas and useful code snippets. Among these is an obsession for recording notes to keep track of projects, interesting ideas, and helpful code snippets. Brett uses a number of custom scripts and software packages, most of which are exclusive to his platform of choice, OS X. To be honest, I find this incredibly intriguing, and potentially useful. So, I've been thinking about developing a command-line tool I can use to interact with phpTodo. A web service could make this a great deal easier.
I have no plans to stop working on the project, and, in fact, I'm eager to keep moving forward. As I continue to rely on phpTodo itself for my daily work, I rely on improvements I can make to the system. So overall, the future of phpTodo is bright.

So… this happened :
Popular file-sharing website Megaupload shut down
Megaupload shut down by feds, seven charged, four arrested
Megaupload assembles worldwide criminal defense
Department of Justice shutdown of rogue site MegaUpload shows SOPA is unnecessary
And then.. This happened :
Megaupload Anonymous hacker retaliation, nobody wins
And, of course, the day before all of this happened was the SOPA/PIPA protest.
Wow.. The government, right? SOPA/PIPA isn't even on the books, people are up in arms over it, and then they go and seize one of the largest file sharing websites on the planet! We should all band together and immediately protest this illegal seizure!
But wait.. hang on.. Since when does jumping to conclusions help? Let's take a look and see what exactly is going on here.. According to the indictment, this case went before a grand jury before any takedown was performed. Additionally, this wasn't an all-of-a-sudden thing. Megaupload had been contacted in the past about copyright violations and failed to deal with them as per established law.
There are a lot of people who are against this action. In fact, the hacktivist group, Anonymous, decided to display their dictate by performing DDoS attacks against high profile sites such as the US DoJ, MPAA, and RIAA. This doesn't help things and may actually hurt the SOPA/PIPA protest in the long run.
Now I'm not going to say that the takedown was right and just, there's just not enough information as of yet, and it may turn out that the government was dead wrong with this action. But at the moment, I have to disagree with those that point at this as an example of an illegal takedown. As a friend of mine put it, if the corner market is selling illegal bootleg videos, when they finally get raided, the store gets closed. Yes, there were legal uses of the services on the site, but the corner store sold milk too.
There are still many, many copyright and piracy issues to deal with. And it's going to take a long time to deal with them. We need to be vigilant, and protesting when necessary does work. But jumping to conclusions like this, and then attacking sites such as the DoJ are not going to help the cause. There's a time and a place for that, and I don't believe we're there yet.

You may have noticed that a number of websites across the Internet today have modified their look a bit. In many cases, the normal content of that site is unreachable. Why would they do such a thing, you may ask? Well, there are two proposed laws, SOPA and PIPA, that threaten what we, today, enjoy as the Internet. The short version of these laws is that, basically, if you're found to have any material on your website that infringes copyright, you face having your website shut down, without due process, all of your advertising pulled, being stricken from search engines, and possible jail time. Pretty draconian. There are a number of places that can explain, in more detail, what the full text of the legislation says. If you're interested, check out americancensorship.org or eff.org.
Or, you can check out this video, from ted.com, that explains the legislation and why it's so bad.
If you're coming here after the 18th of January, here are some images of the protesting.

Back in October of 2011, a bill was introduced in the House of Representatives called HR.3261, or the "Stop Online Privacy Act (SOPA)." Go take a look, I'll wait. It's a relatively straightforward bill, especially compared to others I've looked at. Hell, it's only 15 pages long! And it's going to kill the Internet.
Ok,ok.. It won't *KILL* the Internet, but it has the potential to ruin what we consider to be the Internet. Personally, I believe that if this passes, it has the potential to turn the Internet into nothing more than a collection of business websites, at least in the US.
So how does this thing work? Well, it's actually pretty straightforward. If your website is suspected of infringing on copyrighted material, your website is taken down, any advertising you have on your site is cut, and you are removed from search engines. But so what, you deserve it! You were breaking copyright law!
Not so fast. This applies to *any* content on your website. So if someone comments on a blog entry, or you innocently link to a website that infringes copyright, or other situations out of your control, you're responsible. Basically, you have to police every single comment, link, etc. that appears on your website.
It's even worse for service providers since they have to do the blocking. Every infringing site is blocked via DNS. And since the US doesn't have control of all of DNS, and some infringing sites are not located in the US, this means we move into the realm of having DNS blacklist files. The ISP becomes the responsible party if they fail to block these sites, which in turn means more overhead for the ISP. Think you pay a lot for Internet access now?
So what can you do? Well, for one, you can contact your representative and tell them how insane this whole idea is. And you can protest SOPA itself by putting up a protest overlay on your site. There's a github project with all of the source code you need to add an overlay to your website. Or, if you have a Serendipity web blog, you can download the Stop SOPA plugin I've written.
Get out there and protest!

Imagine a world where you can login to your computer once and have full access to all of the functionality in your computer, plus seamless access to all of the web sites you visit on a daily basis. No more logging into each site individually, your computer's operating system takes care of that for you.
That world may be coming quicker than you realize. I was listening to a recent episode of the PaulDotCom security podcast today. In this episode, they interviewed Jason Fossen, a SANS Security Faculty Fellow and instructor for SEC 505: Securing Windows. During the conversation, Jason mentioned some of the changes coming to the next version of Microsoft's flagship operating system, Windows 8. What he described was, in a word, horrifying…
Not much information is out there about these changes yet, but it's possible to piece together some of it. Jason mentioned that Windows 8 will have a broker system for passwords. Basically, Windows will store all of the passwords necessary to access all of the various services you interact with. Think something along the lines of 1Password or LastPass. The main difference being, this happens in the background with minimal interaction with the user. In other words, you never have to explicitly login to anything beyond your local Windows workstation.
Initially, Microsoft won't have support for all of the various login systems out there. They seem to be focusing on their own service, Windows Live, and possibly Facebook. But the API is open, allowing third-parties to provide the necessary hooks to their own systems.
I've spent some time searching for more information and what I'm finding seems to indicate that what Jason was talking about is, in fact, the plan moving forward. TechRadar has a story about the Windows 8 Credential Vault, where website passwords are stored. The credential vault appears to be a direct competitor to 1Password and LastPass. As with other technologies that Microsoft has integrated in the past, this may be the death knell for password managers.
ReadWriteWeb has a story about the Windows Azure Access Control Service that is being used for Windows 8. Interestingly, this article seems to indicate that passwords won't be stored on the Windows 8 system itself, but in a centralized "cloud" system. A system called the Access Control Service, or ACS, will store all of the actual login information, and the Windows 8 Password Broker will obtain tokens that are used for logins. This allows users to access their data from different systems, including tablets and phones, and retain full access to all of their login information.
Microsoft is positioning Azure ACS as a complete claims-based identity system. In short, this allows ACS to become a one-stop shop for single sign-on. I log into Windows and immediately have access to all of my accounts across the Internet.
Sounds great, right? In one respect, it is. But if you think about it, you're making things REALLY easy for attackers. Now they can, with a single login and password, access every system you have access to. It doesn't matter that you've used different usernames and passwords for your bank accounts. It doesn't matter that you've used longer, more secure passwords for those sensitive sites. Once an attacker gains a foothold on your machine, it's game over.
Jason also mentioned another chilling detail. You'll be able to login to your local system using your Windows Live ID. So, apparently, if you forget your password for your local user, just login with your Windows Live ID. It's all tied together. According to the TechRadar story, "if you forget your Windows password you can reset it from another PC using your Windows Live ID, so you don't need to make a password restore USB stick any more." They go on to say the following :
You'll also have to prove your identity before you can 'trust' the PC you sync them to, by giving Windows Live a second email address or a mobile number it can text a security code to, so anyone who gets your Live ID password doesn't get all your other passwords too – Windows 8 will make you set that up the first time you use your Live ID on a PC.
With this additional tidbit of information, it would appear that an especially crafty attacker could even go as far as compromising your entire system, without actually touching your local machine. It may not be easy, but it looks like it'll be significantly easier than it was before.
Federated identity is an interesting concept. And it definitely has its place. But, I don't think tying everything together in this manner is a good move for security. Sure, you can use your Facebook ID (or Twitter, Google, OpenID, etc) already as a single login for many disparate sites. In fact, these companies are betting on you to do so. This ties all of your activity back to one central place where the data can be mined for useful and lucrative bits. And perhaps in the realm of a social network, that's what you want. But I think there's a limit to how wide a net you want to cast. But if what Jason says is true, Microsoft may be building the equivalent of the One Ring. ACS will store them all, ACS will verify them, ACS will authenticate them all, and to the ether supply them.
