We recently presented Tiny Tiny RSS to you as a great alternative to Google reader, which is one more way you can extend the functionality of your home server or your hosting space. Hopefully, you already exported your data from Google Reader. In this post, we will show you how to secure TT-RSS reader to prevent unauthorized access. Tiny Tiny RSS is an open source web-based news feed (RSS/Atom) reader and aggregator, designed to allow you to read news from any location, while feeling as close to a real desktop application as possible. As we previously explained, it makes an ideal candidate to replace Google Reader. While there are services like Feedly and Newsblur grabbing the crowd Google Reader, which some of you may prefer, there are a group of people who would like to run a RSS reader on their own server and keep things private. Assuming that you have already installed Tiny Tiny RSS on your alternative to Google reader or hosting space, we will now show you how to secure TT-RSS reader.
Secure TT-RSS Reader
One of the main reasons to move to an RSS aggregator like TT-RSS is maintaining your privacy. So if you do not secure TT-RSS reader well you are not only making your data available public but also making your system vulnerable to potential attacks. Choosing a strong username and password while setting your TT-RSS is the first basic thing that you can do to secure TT-RSS reader. Listed below are few more ways you can increase TT-RSS readerâs security.
1. Rename TT-RSS Folder
One of the first lines of defense is to not use tt-rss in your URL to access your TT-RSS reader. To do this on your hosting account, use a folder name other than tt-rss while installing TT-RSS. On your Linux home server, edit /etc/tt-rss/apache.conf and change the first /tt-rss to something else. An example is shown below.
TT-RSS Rename URL
TT-RSS Rename URL
After making the change, restart your TT-RSS and Apache to apply the changes:
sudo service tt-rss restart
sudo serivce apache2 reload
Your TT-RSS reader is now available through the new URL (example: http://mydomain.com/myreader) only.

2. Enable SSL
Accessing TT-RSS through http sends all information as unencrypted data. This could mean less privacy due to potential sniffing. The solution is to encrypt the data during transfer, which makes sniffing by hackers harder. To enable and enforce HTTPS access on Linux servers with Apache, install the following run-time libraries:
sudo apt-get install libssl0.9.8 libpam0g openssl
Restart your Apache server as shown above. You should now be able to access your TT-RSS reader with HTTPS. Note that you may have to have a SSL certificate generated. Refer to Apache documentation if you want to generate your own certificate. By default, the system will install self-signed certificates for you. These certificates are likely to raise warnings when you point your browser to the site.
3. Disable Single User Mode
By default the single user mode is already disabled (in /etc/tt-rss/config.php). Enabling single user mode will also disable TT-RSS login system. Therefore, keep the single user mode disabled.

Disable Single User Mode
A better way to make it a single user system is by limiting the number of registrations to 1 as described below. For whatever reason, you still want to enable single user mode, make sure you implement Apache Authentication method described below.
4. Self Registrations
Self registrations allow a visitor to register themselves, which could reduce TT-RSS security. If your TT-RSS will be for personal use only, then you may want to disable user registration by setting âENABLE_REGISTRATIONâ to âfalseâ.

To further secure TT-RSS Reader, uou may also want to change âREG_MAX_USERSâ to â1â to make your account the only account on TT-RSS.

5. Apache Authentication
Last but not the least, enable Authentication. This is even more important if you have enabled âSingle User Modeâ describe above. Every time you access TT-RSS, you will be asked for a username and password as shown in the picture below:
Secure TT-RSS Reader
On your hosting account this equivalent to password protecting a directory, in this case the TT-RSS directory. To do this on your Ubuntu server, you will have to create a .htpasswd file. More information is available in Apache documentation. But the easiest way to achieve this is to use one of the htpasswd generators available online.
After you enter the username and password two code blocks will be generated. Copy the contents of the .htpasswd code block and save it to /etc/apache2/.htpasswd_ttrss. Next, copy the contents of the .htaccess code block and add it to /etc/tt-rss/apache.conf as shown below:
TT-RSS Apache Authentication
TT-RSS Apache Authentication
Save and exit. Restart both TT-RSS and Apache previous shown above. You should be prompted for a password every time you try to access TT-RSS. Some may think that this double authentication method is an extra inconvenience. But I would rather be safe than sorry.
Go ahead, secure Tiny Tiny RSS Reader and enjoy reading articles on your private secure RSS Reader.

A cathartic experience. As a composer, musical sound designer, and performer my lifelong passion/goal is to give listeners exactly that. Through works that evoke a sense of mood, mystery, and otherworldliness.
To achieve this, in a given composition I make a landscape of voice and/or instrumentation layered with heavily morphed samples and altered field recordings. The juxtaposition of familiar with supra-familiar gives the listener the experience of melody/harmony as a guiding light while giving voice to sonic geography of forms and energies unable to exist naturally in our matter-based world.
Bel canto voice training, impressionist and futurist composers, glitch and industrial/ambient genres all figure into what comprises my influences.
My professional experience includes composing, musical sound design, scoring, recording foley and dialogue, and creating sound effects for independent film. My work also appears on a number of collaborations on CD and vinyl currently floating around the globe, with works-in-progress slated for near-future release.

Ah, passwords. Love âem or hate âem, theyâre a necessary evil of the digital age. The reality is we all end up with an alphabet soup of passwords spread over dozens of various sites and services across the internet. Whilst we might not always practice it, we all know the theory of creating a good password; uniqueness, randomness and length. The more of each, the better.
Of course we frequently donât do this because of all sorts of human factors such as convenience, memory or simple unawareness of the risks. Still, when itâs a case of individuals electing not to create secure passwords, they really only have themselves to blame.
But what happens when the website wonât allow you to create a secure password? Or at least when they severely constrain your ability to create long, random, unique passwords? And what about when they donât allow you to send it between your computer and their server securely?
Even worse, what happens when our most âsecureâ institutions implement lazy password policies? Unfortunately, all of this is pretty rampant practice.

914 Social Sound Design is a Q&A site for Sound Designers.
Social Sound Design is a Q&A site encompassing all the wonderful disciplines of sound design:
Film, game, art and installations, sound effects, new media, software, programming (Max/MSP; Pd, etc.), Arduino and micro-controllers, gear, feedback, recording, techniques and tips...
As long as it involves sound design, it is welcome here!
What an amazing instrument! The DSI Evolver has the signature "old school" timbre down pat as well as being able to provide digital timbres reminiscent of the Waldorf Q. There's certainly a "rougher" side available as well with all the feedback implementation and controled distortion. Being able to make PM type plucked and blown sounds is just icing on the cake. Dave Smith should be commended for a job well done. Just have a look at the Panel Layout to get a taste of what this beauty can dish out - the controls are pretty much laid out in the form of a signal path graphic. Be sure to visit Dave Smith's Website!
Evolver Sound Examples
There are a lot of demos of the Evolver on the web showcasing the gutsy harsh sounds of this beast so I decided to post demos of some of my own patches as examples of the "softer" more "vintage" side of the Evolver's timbre. I make no apologies for these unpolished recordings - these are merely sound samples ;)
Resonant Plucked Pad
This pad shows some of the rich resonant nature of the filter.
This is a simple analog brass lead patch.
A fun patch with lots of motion made using my "Audio-rate Filter FM" programming tip below.
A nice bland-vanilla pad ^_^
What can I say? I love pads...
For more MP3 demos showing the full gamut of sounds the Evolver and Polyevolver are capable of, please visit the excellent website of Stefan Trippler!
The Definitive Guide to Evolver
This rather in-depth guide to the Evolver goes places and does things a mere manual can't. This labor-of-love was crafted by Anu Kirk and with his kind permission, I am offering this fantastic resource right here in PDF format!
A much smaller version (400K) is here but it dosen't have internal hyperlinks.
Here's a fun repository of programming tips for the Evolver in all its incarnations. Please email me if you would like to add some.
Fingered Wave Sequence
Submitted by Dave Bryce. This brilliant technique has to be heard to be believed! Plus, its one of those cool things unique to the Evolver! This particular tip is so full of detailed information that it gets its own page!
Audio-rate Filter FM
Submitted by James Maier. Use the "Audio Mod" parameter in the Filter section to frequency-modulate the cutoff with the analog oscillator. Add resonance until the filter is just on the edge of oscillation then mod the cutoff with just a little triangle LFO set at a very slow speed. Amazing moving chorusing pad and lead sounds can be made this way.
Fatter Bass/Pad Sounds
Submitted by Mike Peake. Set the same sound in both channels (detuned saws, for instance). With the filters at the 24dB setting, increasing resonance cuts the passband as on the Moog filters. Set Envelope 3 to minimum attack, maximum decay and release, and sustain to maximum. This "creates" an offset, a continuous "on" signal while the keys are gated. Modulate one filters' resonance up (just one), or of the overall resonance level is high, us it to modulate one filters' resonance to its minimum. You get the resonant character plus the size of the non-resonant filter. Use Tri and Sine waves on that side too.
Submitted by James Maier. The Evolver can make many ultra-bright and buzzy sounds due to its extensive feedback and distortion stages but sometimes people miss the subtler side of the beast. For a warmer sound use little or no distortion, close the filter just a bit and turn off the feedback and delay lines. I've managed to get dead-on Prophet5 timbres this way.
Submitted by Mike Peake. Set the envelopes to linear, and use a Mod to modulate AmpEnv All by itself (lin through log responses with positive and negative self-modulation).
This is of course fun on the filter envelopes as well.
More Vintage Character
Submitted by Mike Peake. Oscillator Slop, set at 5, doesn't come close to the Moog and other old-timer movement, so add slight (1 or 2) LFO to pitch modulations, with individual LFOs per oscillator, and a touch of LFO to LFO rate modulation. A tad of Envelope 3 to pitch helps as well.
Don't miss out on the 12dB filter setting
Submitted by Mike Peake. The 24dB setting has much more resonance, but the 12dB setting can sound nice and plucky, and do nice slightly fuzzy pads etc.
DSI Evolver Waveshape Charts
Below are charts I've assembled of the digital waveforms and their spectra as currently used in the DSI Evolver synthesizers. Originally these waves were unique to the SCI ProphetVS vector synth.
I find these waveform/spectra graphics really usefull when programming sounds - maybe you will as well. Pay special attention to the spectra as this info is sometimes much more useful than waveshape in determining actual timbre - even before you hear what the waveform sounds like.
These are designed to be downloaded (right-click & "save target as"), and printed at 300dpi on 8.5" x 11" pages - don't resize these images before printing or you will lose useful detail. Use them as a handy refrence. This information was cobbled together from various scattered sources (with very special thanks to Achim Gratz!).
Any errors or omissions are my own. ^_^
As far as the origin of these waves is concerned, one of the original VS engineers, Chris Meyer, said:
"The original waves for the VS were created three ways - extracting single-cycles from sampled sounds, using a custom additive synthesis program, and using a program Josh (Josh Jeffe, another VS engineer) slapped together called "Hacker" where you could draw the waveshape. These were fed straight from the computer through the filter and VCA of a Pro-One to figure out what they might sound like in a patch. And by the way, no PPG waveforms appear inside the VS - we had access to them, but in the end our consciences got the better of us. We did steal some waveforms from the Korg DW6000, but only by looking at the harmonic drawings on the front panel and trying to imitate them in our additive synthesis program."
Modulation Matrix "Cheat Sheet"
This chart shows all the modulation routing available on the Evolver. This same info is available in the manual but this can be printed on a single sheet of paper as a handy refrence!
These I created just for fun and desktop "beautification" ;)

About Beat Hauser, SPERRZONE
Beat Hauser is interested in industrial archaeology and history of Europe. His special area is the brewing industry of Switzerland and the former German Democratic Republic. Since 2003 he is taking pictures of industrial areas and abandoned places within all Europe. On his web site SPERRZONE (www.sperrzone.net) he does not only present his own pictures, but also some information about the related factories and places as well as historical photo post cards, old letter heads, labels, advertisings to document the history of the factories.
Most pictures are taken in abandoned factories. Abandoned places and industrial ruins are generally seen as Ă˘ÂÂspots of dirtĂ˘ÂÂ and people feel uncomfortable around them. Often such places have a very long and interesting history, which seems almost forgotten today. Instead of the activity of former days there is nothing but silence and emptiness. Instead of windows, black holes are staring out of the walls. But very often the architecture of elapsed eras is attractive and astonishing. In combination with the emptiness and beginning decay, such places often spread the impression of a dream world. Decay and nature give new structures to strictly geometric forms and lines, e.g. in production halls. Moisture, moss and rust give new colors to gray halls. Beat Hauser tries to capture these impressions with his photographs. Aesthetics of decay is illustrated in its huge variety from huge industrial plants to small details.

767 The 5 types of programmers ÂŤ Steven Benner's Blog
In my code journeys and programming adventures Iâve encountered many strange foes, and even stranger allies. Iâve identified at least five different kinds of code warriors, some make for wonderful comrades in arms, while others seem to foil my every plan.
However they all have their place in the pantheon of software development. Without a healthy mix of these different programming styles youâll probably find your projects either take too long to complete, are not stable enough or are too perfect for humans to look upon.
The code may not be pretty, but damnit, it works!
This guy is the foundation of your company. When something goes wrong he will fix it fast and in a way that wonât break again. Of course he doesnât care about how it looks, ease of use, or any of those other trivial concerns, but he will make it happen, without a bunch of talk or time-wasting nonsense. The best way to use this person is to point at a problem and walk away.
You want to do what to my code?
This guy doesnât care about your deadlines or budgets, those are insignificant when compared to the art form that is programming. When you do finally receive the finished product you will have no option but submit to the stunning glory and radiant beauty of perfectly formatted, no, perfectly beautiful code, that is so efficient that anything you would want to do to it would do nothing but defame a masterpiece. He is the only one qualified to work on his code.
Iâm a programmer, damnit. I donât write code.
His world has one simple truth; writing code is bad. If you have to write something then youâre doing it wrong. Someone else has already done the work so just use their code. He will tell you how much faster this development practice is, even though he takes as long or longer than the other programmers. But when you get the project it will only be 20 lines of actual code and will be very easy to read. It may not be very fast, efficient, or forward-compatible, but it will be done with the least effort required.
What do you want? It works doesnât it?
The guy who couldnât care less about quality, thatâs someone elses job. He accomplishes the tasks that heâs asked to do, quickly. You may not like his work, the other programmers hate it, but management and the clients love it. As much pain as he will cause you in the future, he is single-handedly keeping your deadlines so you canât scoff at it (no matter how much you want to).
Well, thatâs a possibility, but in practice this might be a better alternative.
This guy is more interested the options than what should be done. He will spend 80% of his time staring blankly at his computer thinking up ways to accomplish a task, 15% of his time complaining about unreasonable deadlines, 4% of his time refining the options, and 1% of his time writing code. When you receive the final work it will always be accompanied by the phrase âif I had more time I could have done this the right wayâ.
Personally, Iâd have to classify myself as the perfectionist. So, which type of programmer are you? Or perhaps you know another programming archetype that is missing from my list? Post a comment below and Iâll add it to a new updated list.
720 Common Security Mistakes in Web Applications - Smashing Magazine
Web application developers today need to be skilled in a multitude of disciplines. Itâs necessary to build an application that is user friendly, highly performant, accessible and secure, all while executing partially in an untrusted environment that you, the developer, have no control over. I speak, of course, about the User Agent. Most commonly seen in the form of a web browser, but in reality, one never really knows whatâs on the other end of the HTTP connection.
There are many things to worry about when it comes to security on the Web. Is your site protected against denial of service attacks? Is your user data safe? Can your users be tricked into doing things they would not normally do? Is it possible for an attacker to pollute your database with fake data? Is it possible for an attacker to gain unauthorized access to restricted parts of your site? Unfortunately, unless weâre careful with the code we write, the answer to these questions can often be one weâd rather not hear.
Weâll skip over denial of service attacks in this article, but take a close look at the other issues. To be more conformant with standard terminology, weâll talk about Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), Phishing, Shell injection and SQL injection. Weâll also assume PHP as the language of development, but the problems apply regardless of language, and solutions will be similar in other languages.

74 The RayographsBlog MySpace de |
The Rayographs are Astrud Steehouder on guitar and vocals, Jessamine Tierney on bass and vocals and Amy Hurst on drums and occasional vocals.
