5 Simple steps to secure TT-RSS reader
July 27, 2015 by Anand Leave a Comment
Share: share htpcBeginner
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.

1517 THE MUTANT MACHINE Dynamic Analog Percussion Engine
MICROCONTROLLER FREE ANALOG PERCUSSION SYNTHESIS
unique Inverter Core oscillators form the MEMBRANE. Each analog oscillator has three waveforms to select from
capable of synthesizing everything from heavy-hitting bassdrums to classic 909-style snares and other complex timbres
modular design gives the Machine many auxiliary purposes, great for modular sound design of many varieties, and not just percussion
the SNAPPY section is comprised of a voltage controlled noise oscillator, for modelling the noisy part of drum timbres
both MEMBRANE and SNAPPY elements have an external input for replacing the built-in sound sources, opening up many avenues of possibility
13 control voltage and audio inputs, for a fully modular drum experience
7 audio and CV/gate outputs for maximum integration with other modules
dedicated outputs for each WAVE and NOISE oscillator mean you can use the Machine as a complex VCO in your system, when not synthesizing percussion
WAVEFORM SCANNING FEATURE GENERATES COMPLEX TIMBRES
the MEMBRANEâs waveforms can be scanned through automatically by the wavescannerâs voltage controlled clock generator, or an external clock or VCO can be used
SCAN FREQ CV forms a unique form of timbre control, making the Machine act like a complex oscillator at its WAVES output
the ENABLE input allows you to gate the wavescanner on and off with a CV or gate signal
ARCHITECTURE OF THE MACHINE
The Mutant Machine is a dynamic analog instrument capable of generating a wide palette of sounds, ranging from various forms of analog percussion to complex drones and oscillations. To achieve this, the Machine features two synthesis sections which are summed together at the final output: MEMBRANE and SNAPPY. Like the other Mutant Drums, the MEMBRANE and SNAPPY circuits began their mutation as classic analog percussion techniques and have been reimagined for 21st century modular synthesis.
The MEMBRANE forms the main body of the sound by way of two analog VCOs, and the SNAPPY section further adds to the timbre by contributing noisy elements to the mix. A noisy CLICK which occurs at the beginning of the SNAPPY sound can have its volume adjusted independent of the main decaying SNAPPY texture.
The waveforms which make up the MEMBRANE can be selected manually by button press, or the WAVESCANNER can be used to automatically scan through the available analog waveforms. By modulating the frequency through which waves are scanned, unique, complex sounds are created.
Experimentation is encouraged by the many modulation inputs and outputs available to you. The Machine features 8 CV and gate inputs for modulation as well as two external audio inputs, for bringing other modules into the Machineâs core. There are many audio outputs for maximum versatility, allowing you to use the Machine to create drones and alien timbres for use elsewhere in the modular analog system.

1502 Phone-Reluctant Introverts, There is Nothing Wrong With You
As I sit down to write this blog post there is the dreaded sound of a prolonged vibration as my phone skids, bouncing and sporadically across my desk. This is perfectly ideal and ironic distraction that actually befits the very thing I am thinking about and from which it is distracting meâŠ Itself!
I have always had an absolute detest for talking on the phone. And Iâll say now that it has nothing whatsoever to do with the person at the other end, I just find it a horrible tool for communicating with.
I think I probably am, and always have been worse than most people when it comes to using the phone (in the traditional sense, ie speaking to people) but if you can identify with any of this then read on. If youâre thinking, âwhat are you on about, I love the phoneâ then youâll probably just get confused, but if you also have friends who ânever answer the phoneâ then this might help you to understand them a bit better.
I canât sum it up any better than Sophia Dembling in her article, 9 Signs that You Might Be an Introvert:

Cut simple SMT Stencil from common aluminum flashing on your CNC
Hereâs a quick photodoc of how I made a reusable SMT stencil from some aluminum siding I had laying around. Itâs very simple to assemble and works great. Dirt cheap too.
I had picked up a roll of aluminum flashing a few years ago to flash some chimneys I rebuilt/repointed and was curious to see how it would hold up as an SMT stencil.
To buy an SMT stencil frame is near $1000 so I didnât have much to lose if it didnât work out.
I cut the frame out of some birch plywood since I had some handy. Really any sturdy frame would do the trick. You could easily glue one together out of some 1x or trim board.
I put a thicker sheet of aluminum down underneath the flashing to give the CNC endmill something sturdy to cut against and clamped it down stretched and tight. My thought there was that If I cut straight on the MDF it might push on the flashing and bend it before it cut through.
A 1mm endmill did the trick. Each pass was .05mm deep.
I pulled the Flashing tight and stapled it to the frame. No rocket science here. I taped up the inside edges so no solderpaste could squeeze between the frame and the stencil.
I had some old screen print hinge boards so I just attached this frame the same way I would a screen print stencil.
The only fiddly part was aligning the first PCB. You have to push around a little and lift the stencil and fiddle with it a little bit. Once I get all the pads lined up correctly I hold it in place and trace around it with a thin tip sharpie marker.
Then you place the PCB in the outline. If you have the height adjusted correctly the stencil is sturdy enough to hold the PCB in place while you print the Solderpaste on it. just hold the stencil frame down and it pushes down on the PCB.
I used a flexible putty knife as a squeegee. It worked fine.
Cleanup was a breeze. Just scrape it off, unscrew the stencil frame from the hingeboard and stick it in the corner till you are ready to do another run.

1386 Retro Synth Ads: Sound Master Memory Rhythm SR-88, Keyboard 1982
Sound Master Memory Rhythm SR-88 drum machine 1-page advertisement from page 67 in Keyboard Magazine August 1982.
Hmmm. Not sure how I feel about this ad. There just seems to be a lot going on.
For example, am I supposed to know who "The Rhythm Section" is? The fact that they include themselves in an already long ad title suggests they must be some kind of a big deal. And then you find their name again in the bottom left-hand corner:
"The SR-88. Another innovative product from The Rhythm Section by Sound Master Distributed exclusively by JTG of Nashville."
So, let me get this straight. JTG of Nashville is the distributor of the SR-88 which was created by The Rhythm Section which is somehow owned or operated by Sound Master.
That is waaaaay to much information. Sounds like something political is going on there, and readers unfortunately get stuck in the middle of it.
There also seems to be a lot of ad-copy which actually doesn t give me much information. Reason #4 gives readers the most info including instant stop/start, variable tone and output switches, and a write/play mode indicator. The most I glean out of the four other reasons put together is: 16 rhythms, clock pulse and a price of under $200.
The actual specs that are probably most important to potential buyers are inexplicably shoved into the bottom right-hand corner.
Luckily for me, there are a few resources on the Web with more information about this beast. Unluckily for blog readers, as soon as I started looking for more info, I got swept up in a certain SR-88/Boss DR-55 controversy.
Comparing the SR-88 and Boss DR-55
One of the first Web sites I hit while looking for info on the SR-88 was Dubsounds.com. The site includes a great little write-up on the SR-88, but, more interesting was finding out about a little controversy about whether the SR-88 or the very similar Boss DR-55 came out first.
The two do seem mighty similar in functionality. For comparison purposes, I did a quick search on MATRIXSYNTH to find more photos. . A great photo of a gray SR-88 can be found in this December 2005 SR-88 MATRIXSYNTH auction post and the less common, but definitely more cool, blue SR-88 can be seen in this January 2011 MATRIXSYNTH auction post.
Comparing the two to the Amdek RMK-100
Interestingly, it s not just these two machines that look and function similarly. In this May 2009 MATRIXSYNTH SR-88 auction post commenter "PAC" notices:
"Interesting. I have an Amdek RMK-100 (sold as kit), very similar!"
Never heard of it, so I Googled "Amdek RMK-100" to see just how similar it was to both the DR-55 and the SR-88. Turns out (according to the Internet) that Amdek products were made by Boss/Roland back in 80s, and, not only that, but that the RMK-100 is actually the kit version of the Boss DR-55. Makes sense on why it would also be similar to the SR-88.
I found an ebay auction for an Amdek RMK-100 going on right now with a great photo of the front panel (see below), and indeed it does share a lot with the DR-55 and SR-88 - but definitely not identical to either one.
For example, it looks like the Amdek and SR-88 share a similar filler function that as far as I can tell is not available on the DR-55. And the DR-55 and the RMK-100 share a similar accent function that I don t see on the SR-88.
Now where does the Electro Dynamics Corporation Programmable Rhythm SR-99 fit in?
I also came across another machine with similar features - the Programmable Rhythm SR-99. No - not manufactured by Sound Master, but by Electro Dynamics Corporation. And, it too resembles the others in functionality, and especially the SR-88 in design also.
I ve included a row of photos below to help make the comparison between the two. The SR-88 photo is from the 2005 MATRIXSYNTH auction post and the EDC SR-99 photo is from the excellent BigBlueWave.co.uk site. I ve also thrown in a photo from another recent E-bay listing that included both - plus boxes and manuals! Sick!
Obviously, Sound Master and EDC are somehow connected, although I can t find any info on the Internet concerning these two companies. I do know that they were both advertising separately in Keyboard Magazine in late 1983, making it unlikely that one of the companies changed their name to the other. Anyone know anything?
And then there is the Clef Master Rhythm...
Now, I m going to throw in a late entry. It s Sunday night, and I just came across this August 2010 MATRIXSYNTH auction post for the Clef Master Rhythm. It not only shares part of the name of one of the other units ("Master"), it too has many features of the other rhythm machines, and identical innards as the DR-55, but is expanded to include even more sounds:
"This is essentially a fully expanded Boss DR-55 feature-wise and tone-wise. The circuits are identical (schematically and tonally) to the Boss DR-55, but the Clef Master Rhythm gives you way more instruments than the Boss DR-55..."
Interestingly, according to the post, it pre-dates the Boss DR-55 - and also came in a kit form like the Amdek.
"The Clef Master Rhythm came out a little before the Boss DR-55 in late 1979/early 1980. It was sold in two versions and available in greater quantities in Europe than in the United States. One version was a kit that the user put together and another one was a prebuilt machine."
A photo from the MATRIXSYNTH post really helps show the similarities in functions with the others:
What does it all mean?
So, looking at all five machines, its almost like there was a rhythm machine salad bar of some sort in Japan, and each company stepped up to it and picked out which features they wanted to include in their product.
And that begs the question - since we know there was a kit form available and there are claims that the Clef Master even has the same circuits as the DR-55, could all five products (and probably others) have used the exact same internal parts - each company choosing which features to include and then customizing in their respective rhythm machine? And if so, were those parts supplied by Amdek, or did all five get their internal parts from some other manufacturer?
And if that is the case, then the question of whether the SR-88 or DR-55 came first doesn t really matter much, since it is likely that the kit components would have been available first. Plus, we have that one auction post with the claim that the Clef Master came out before the DR-55 - making it all even more confusing to figure out.
Or, am I totally off the mark on all this? Were they all created separately? Maybe I ve just been fixated on this a little too much...
I ll keep on looking for more info on these companies and any connection they might have, but if anyone want to buy all four and open them up to take a look - it would be muchly appreciated. :D

Here s a funny thing - I seem to remember Clef in the early 1980s as a British company that made electronic pianos (touch-sensitive ones!) in kit form. Deep in the back of my mind I recall seeing them at a music fair in London with a couple of their pianos and some drum machines including a prototype drum/bass/chord sequencer called something like a "Band-Box". But it WAS a long time ago.

Looks like (for once) my memory didn t fail me. Here is a 1982 ad for Clef Electronics showing all the products I mentioned, plus a natty-looking little monosynth! BTW, I owned an EDC SR99 drum machine in the mid-1980s, but replaced it with a Yamaha RX-21 a couple of years later.

MidiVox CV sketch update
The MidiVox CV sketch has been updated to work with Arduino 1.0 - grab it here
Also be sure to use the new version of the Midi Library as well!
Also, also: Some previous comments on earlier posts seem to have been lost in a recent Disqus migration - apologies to previous commenters.
Updated Midi Library & site changes
Perhaps you noticed narbotic.com looks different? It is different!
A big thanks to everyone who picked up a MidiVox kit - you are now the proud owner of a rare piece of electronics.
Though the kit is no longer in production, there is now a new version of the Midi Libray which has been updated to work with the Arduino 1.0 IDE.
In addition to an aesthetic reboot, this site will now serve as your premiere destination for all things Collin Cunningham on the web. (and I vow that will be the one & only time I refer to myself in the third-person)
New things are in the works - more to come
