1522 5 Simple steps to secure TT-RSS reader
secure tt-rss, tt-rss security 5 Simple steps to secure TT-RSS reader July 27, 2015 by Anand Leave a Comment secure-tt-rss-ft 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 reader’s 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. Amazon Kindle Fire HDX 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 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 “ENABLE_REGISTRATION” to “false”. TT-RSS Self Registrations TT-RSS Self Registrations To further secure TT-RSS Reader, uou may also want to change “REG_MAX_USERS” to “1” to make your account the only account on TT-RSS. asus n66uASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router asus n66u reviewsFind out why it is rated the best wireless router in its class. 5. Apache Authentication Last but not the least, enable Authentication. This is even more important if you have enabled “Single User Mode” 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 MEMBRANE’s waveforms can be scanned through automatically by the wavescanner’s 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 Machine’s 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.

1408 » Cut simple SMT Stencil from common aluminum flashing on your CNC Animodule.com
Cut simple SMT Stencil from common aluminum flashing on your CNC Here’s a quick photodoc of how I made a reusable SMT stencil from some aluminum siding I had laying around. It’s 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 didn’t have much to lose if it didn’t 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.

1164 Liz Lang at The MAP
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.

I have a non-fitness related life situation that I wanted to run by you guys…. I wanted to talk to you guys today about not always having to say your sorry. Are you one of those people who finds yourself apologizing for things just to smooth things over or avoid a confrontation? This ability is admirable in certain low-key non-crucial situations. It’s when we apologize for our beliefs and principles – or in the face of being bullied that we pay the high price of compromising ourselves. I have a friend who is being treated badly by certain members of her family. It really comes down to her not living her life exactly the way they think she should be living it. My friend is not endangering herself or others, she is kind hearted and generous to the extreme, but because she is not pulling the line and placing the needs of others before her own basic needs and happiness she is taking a lot of undeserved heat bordering on emotional abuse. Her strategy to this point has been to apologize left and right in an attempt to smooth it over and reset everything. It hasn’t worked and if anything it has given the people giving her a hard time more of a license to push it even further. I think there comes a time when you just have to say enough and stop apologizing. I think that there is more strength and balance in believing in yourself and respectfully staying firm in your truth. From this position I think both sides have the best chance of talking it through and resolving it. What do you guys think? Do you find yourself constantly apologizing to certain people in your life? Is it helping or making the relationship more challenging? Any advice for my friend?

865 Evolver.html
Just Beautiful! 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. Soft Lead This is a simple analog brass lead patch. FM Pad A fun patch with lots of motion made using my "Audio-rate Filter FM" programming tip below. Warm Pad 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. Programming Tips 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. "Warmer" Sounds 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. Adding "Punch" 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. ^_^ HAVE FUN!!! Page 1 Page 2 Page 3 Page 4 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! Evolver Wallpaper These I created just for fun and desktop "beautification" ;) 1280 X 1024 1024 X 768 800 X 600

727 How To Create an Antique Mirror Effect | Apartment Therapy DC
How To Create an Antique Mirror Effect Mclain Wiesand, a Baltimore-based custom furniture company, has made a name for itself by producing handcrafted pieces that capture the feel of real antiques. One of the techniques they use for aging mirror is wonderfully simple and serves as the inspiration for this how to. Creating an antique mirror effect is an inexpensive way to revamp a flea market find, or add a new layer of interest and depth to an ordinary wall mirror. Almost any type of mirror can be aged using this technique, including mirrored plexiglass. Supplies • Mirrored glass or plexiglass. Due to the type of paint applied to the reflective coating, inexpensive, craft-store mirror works wonderfully. • Latex or other gloves for hand protection. • Paint stripper. Most types work fine. For a less toxic product, Citristrip works well. • Plastic putty spreader or putty knife. • Modern Masters Metal Effects Black Patina. This patina solution is essentially an acid that eats at the reflective surface of the mirror. There are probably other products that work similarly, but Modern Masters products work well and can be found online or in most art supply stores or specialty paint stores. • 1” chip brush (or similar brush). • Silver paint of choice. Steps Step 1: (Image 2, above) Wearing gloves, place mirror face down on cardboard or other protected surface in a well-ventilated area. Apply stripper generously to back of mirror and allow to sit for a few hours, or until paint can be easily removed with plastic scraper. It is not necessary for all of the paint to be removed; generally speaking, 80-90% should suffice. When paint has been stripped, wash mirror with soap and water and allow to dry. Step 2: (Images 3 & 4) Place stripped mirror face down on clean cardboard or other protected surface. Dip chip brush in Modern Masters Metal Patina Solution and gradually apply it to the raw reflective surface of the mirror. As mirror tends to age from the edges inward, it is best to apply patina solution in heavier amounts around the edges of the mirror. In a matter of minutes (or less), the patina solution will begin to eat away at the reflective surface. Other application techniques that produce nice effects are spattering and light directional brushing of patina solution. Continue applying solution until desired level of ageing is achieved. Rinse with water to neutralize the reaction and allow to dry. Step 3: (photos 5 & 6) This next step involves reapplying paint to the back of the mirror. The color paint you choose will be visible through the spots created by the patina solution. The dark areas of aged antique mirrors tend to be a dark silver-grey but depending on the silvering technique used, can range from gold to pale silver to black. One method that produced nice results is a combination of dark and light silver paints, applied randomly (per images). Apply paint until the reflective surface is completely covered.

704 What Is User Experience Design? Overview, Tools And Resources - Smashing Magazine
Websites and Web applications have become progressively more complex as our industry’s technologies and methodologies advance. What used to be a one-way static medium has evolved into a very rich and interactive experience. But regardless of how much has changed in the production process, a website’s success still hinges on just one thing: how users perceive it. “Does this website give me value? Is it easy to use? Is it pleasant to use?” These are the questions that run through the minds of visitors as they interact with our products, and they form the basis of their decisions on whether to become regular users. User experience design is all about striving to make them answer “Yes” to all of those questions. This guide aims to familiarize you with the professional discipline of UX design in the context of Web-based systems such as websites and applications. [Offtopic: by the way, did you know that we are publishing a Smashing eBook Series? The brand new eBook #3 is Mastering Photoshop For Web Design, written by our Photoshop-expert Thomas Giannattasio.]

701 How To Convince The Client That Your Design Is Perfect - Smashing Magazine
As designers who deal with clients, we all have to face one situation, no matter how difficult and uncomfortable, and that is guiding the client to accept that your design is perfect. Now, you already have the project, so this is not a matter of convincing them to pick you for the job. This is about getting them to see that your design satisfies their requirements and contains everything they want. We all have to take on this role of virtual tour guide and lead them through the project’s twists and turns, ensuring that the best interests of the client and website are served. We have to be the lighthouse, guiding the clients to shore. (Image credit) In the end, the final decision falls to the client, but there are times — and most of us have experienced them — when the client’s lack of expertise in the field affect the quality of the design. In such times, we have a responsibility to do everything in our power to convince the client that the design is perfect as it is, and that any further alteration would impair the website’s ability to communicate everything it needs to. This confrontation is not welcome by either party, but it is certainly necessary. Many designers want to avoid conflict and, as a result, cave to their clients at the slightest sign of disagreement, rather than spend time trying to convince them that they stand on the right side of the design decision. This is often a mistake and does not serve the design, which should be the paramount consideration. We owe it to our creative work to argue for whatever serves the design beyond all else, even though the client is footing the bill. We may end up having to give in to the client, but at least we tried. Below is an overview of some tips and techniques you can employ when you find yourself butting heads with a client. These approaches might work individually or in combination, but they all at least offer a launching point to help you put your best foot forward and lead the client exactly where they need to go.

691 visualizing.org
Visualizing.org is a community of creative people working to make sense of complex issues through data and design… and it’s a shared space and free resource to help you achieve this goal. Why Visualizing.org? By some estimates, we now create more data each year than in the entirety of prior human history. Data visualization helps us approach, interpret, and extract knowledge from this information. Over the last couple of years, we’ve seen government agencies, NGOs, and companies open up their data for the public to see and use. And we’ve seen data visualization figure more prominently in design curricula, conference programs, and the media. We created Visualizing.org because we want to help connect the proliferation of public data… with a community that can help us understand this data… with the general public. What is Visualizing.org? What can I do on the site? For designers: Visualizing is a place to showcase your work, get feedback, ensure that your work is seen by lots of people and gets used by teachers, journalists, and conference organizers to help educate the public about various world issues Visualizing is a free resource to search for data Use Visualizing to keep up with and be inspired by the latest work from other designers and design schools Learn about new visualization tools, blogs, books and other resources to help your work Everything you upload remains your sole and exclusive property and is licensed under a Creative Commons Attribution Non-Commercial Share-Alike License For teachers and schools: Visualizing is a place to exhibit the collective work of your students, organize assignments and class projects, and help your students find data for their own visualizations We’re working on new tools to help you share teaching material with other teachers As an Academic Partner, your students are eligible to participate in various design competitions – we’re hosting the first Visualizing Marathon in New York in October To learn more, contact Saira Jesani For bloggers and journalists: Visualizing is a resource to find data visualizations about a wide variety of world issues to inform and accompany your own reporting – and it’s easy to embed visualizations and widgets from Visualizing on your own site For conference organizers: As a Knowledge Partner, Visualizing allows you to use data visualizations at your conferences under a Creative Commons License To learn more, contact Saira Jesani For all: Visualizing is a new and fun online resource to learn more about the world in all its complexity and inter-dependence -- and become more comfortable with data and how it can be visually represented How does it work?

529 SynthesisWorkshops
synth modular Sound synthesis and sound design Music has brought pleasure and entertainment to mankind throughout the whole of history. Each person is by nature equipped with one of the most elaborate and emotional musical instruments; the human voice. Whenever people feel good music seems to fit the occasion, and it is considered quite natural to hum or sing a song. Musical instruments have brought their own moods to music and at the current moment in human evolution there is an enormous variety of musical instruments available. The twentieth century has seen the development of a range of new and exciting electronic musical instruments. These electronic instruments are very flexible, they can produce a wide range of timbres and can be amplified to whatever loudness level sounds best for the occasion. Most of these electronic instruments are played by a keyboard, but in essence the keyboard can be replaced by any electromechanical device that is able to transform a movement caused by a human interaction into an electrical signal that can drive the sound generating core of the electronic instrument. All sorts of technical and scientific developments have helped to create electronic instruments and the human interface to play them. Still, music is an art and not really a hard science, although music and sound have for a long time been subject to various scientific research. An important realization is that science can not really explain why much music is such a pleasure to listen to and such a joy to make. Which is not a bad thing, as probably no one is waiting for science to take the fun out of music by applying formalized rules and templates on what is also subject to ‘feel’. So, although this book covers techniques that lean heavily on scientific research, the application of these techniques will in general be aimed at creating fun. There are a lot of professionals working with sound and even more people that make music for their personal enjoyment. Mastery of sound synthesis is valuable to all of them. Still, it won’t be easy to please everyone with one single book, as some people will be more interested in how things work and others might want practical examples that just work. The aim of this book is that it can at least be used as a practical guide in workshops and courses in electronic music, covering some essential basics that are needed to operate the equipment used in sound synthesis in a way that makes some sense. Additionally it can be used to explore techniques to find out how they can help in the development of one’s own musical style. Sound synthesis is the art of creating sounds by using suitable electronic means, using either analog or digital electronic devices. Sound design is the art of creating particular sounds using sound synthesis techniques. The definition of sound design as used here might be confusing to some, as the name sound design is also used in the discipline in industrial design that occupies itself with how mass produced objects should sound. Examples are how the sound of cars or ladyshaves are ‘designed’ to sound pleasing while in use. Which of course has nothing to do at all with music or sound synthesizers. This book puts the emphasis on the various synthesis techniques for musical purposes and how to setup sound synthesizers to create a large range of characteristic musical sounds. The art of musical sound design is left to the artist.

300 YAMAHA CS-30 SYNTHESIZER
This page is dedicated to the Yamaha CS-30, the monophonic top-of-the-line of Yamahas CS-series synthesizers. This synthesizer series comprised of the CS-5, CS-10, CS-15 and the CS-30. These were all monophonic. The polyphonic series comprised of the CS-50, CS-60 and the classic CS-80, Later came the CS-30M and CS-40 monophonics as well as the CS-70 polyphonic with some patch saving capabilities and different design. All the units of this series of vintage synthesizers are very nice and collectable, but the CS-30 was the largest and most flexible of the monophonic series. If Yamaha had ever decided to build a large modular system they could have done so using some of the designs of the CS-series. In this page I will go through the features of the CS-30, for anyone interested.

298 The Evolution of Privacy on Facebook
Facebook is a great service. I have a profile, and so does nearly everyone I know under the age of 60. However, Facebook hasn't always managed its users' data well. In the beginning, it restricted the visibility of a user's personal information to just their friends and their "network" (college or school). Over the past couple of years, the default privacy settings for a Facebook user's personal information have become more and more permissive. They've also changed how your personal information is classified several times, sometimes in a manner that has been confusing for their users. This has largely been part of Facebook's effort to correlate, publish, and monetize their social graph: a massive database of entities and links that covers everything from where you live to the movies you like and the people you trust. This blog post by Kurt Opsahl at the the EFF gives a brief timeline of Facebook's Terms of Service changes through April of 2010. It's a great overview, but I was a little disappointed it wasn't an actual timeline: hence my initial inspiration for this infographic.

284 MATRIXSYNTH: Alesis Andromeda A6 Tip
Alesis Andromeda A6 Tip If you own an Andromeda, give this a try. Via this gearslutz thread where you'll find additional details, via mister bunty on AH: "For those that asked, here's the thread on gearslutz that explains the waveshaping that happens above level 30. I know it sounds crazy, but if you keep the levels pre-mix below 30 total (yes, total!) and then the filter/ringmod/postmix levels around 70 at sum, you'll hear a whole new definition. I tried it on a crappy set of headphones and was amazed. Then, I listened through my bluesky monitors and a set of NS-10s, and couldn't believe the detail I had been missing. For me, at least, the juice and "vintage-ness" of the Andy was discovered." http://www.gearslutz.com/board/electronic-music-instruments-electronic-music-production/473535-what-does-andromeda-do-better-6.html#post5206610

235 MATRIXSYNTH: Alesis Andromeda A6 Aurora Mod
This was a custom mod. I originally put a post up in August of 05 here. Anyone know the website where more info on this mod is hosted? I accidentally lost the link when mucking around with Blogger's settings a while back. This image via Photobucket Update: I found the original site but it is down. Some info and additional shots pulled from the Internet Archive Way Back Machine. You can find some thumbnails there, but most give you a 404 if you click on them for the larger shot. I pulled the large pics below before they are gone forever. "Alesis made Synthesis History when they released their Alesis Andromeda A6, an analog polysynth bred with new technology and classic analog sound! Sixteen awesome voices with two types of filters, a vast modulation system, and enough bells and whistles to make the Andromeda A6 THE most highly featured analog polysynth in existence. If it only had a sloped panel... SPECS: * Take one Andromeda, lightly used (but out of warranty - very important!) * Add one black on blue BETA Panel - because the pre-production beta panels were lacking the Pre- and Post-Filter Mix VIEW buttons, either the buttoncaps must be pulled off of the switches on the PCBs OR two holes need to be carefully drilled through the panel to accomodate. I drilled the holes after measuring about fifteen times each. * Tilt that panel at approx. the same slope as the Korg MS-20. Requires the extending of a couple of ribbon cables inside, and some pop-rivetted braces. Not too hard. * Custom wood endcheeks of nice Oak, plus a wood accent over the keyboard. I chose to go with thick, high quality wood to make Aurora more of a beast. * Replace all green LEDs with red high-intensity ones. This also required changing some resistor values to increase the brightness. * Replace the LCD with a Hantronix Blue-on-White display. Also, some resistor changes are needed. * Have a very agreeable Alesis burn a custom Boot EPROM with the custom-designed bootup screen below. * Build a custom top panel, complete with several additional controls (two joysticks, several switches and knobs) as well as a full 16-channel mixer with level and pan per channel, one for each of the 16 individual outs on the Andromeda. * Add lots of careful, hard work and time, and PRESTO - you have the Aurora A6! The Name: I went with Aurora for a couple of reasons. 1. Alliteration - AurorA - AndromedA - get it? 2. There is some legend/lore as to how the Alesis Andromeda got its name. Could be related to the Greek mythos. Could be related to the Andromeda galaxy. Could be darts thrown at dictionary pages :-) In any case, Aurora fits with the mythology bent because in Roman mythology, Aurora was the goddess of the dawn (Andromeda was rescued and married by Perseus in Greek mythos). Aurora also fits the 'celestial' thing as well, as the Aurora Borealis. Either way, it kept with what might have perhaps been Alesis' reasons for naming the Andromeda. 3. I just liked it. 4. The A6 is kept because this fits with Alesis' naming convention (QS8 = 81-key QuadraSynth, A6 = 61-key Analog). There is some rumor that A6 was a play on ASICs, the custom chips within Andromeda, but I'm assured this is just rumor :-) "

229 Typography Is Important - Well-Made Magazine - Techmic Studios
Typography is the art of arranging type and type design. The arrangement of type involves the selection of typefaces, point size, line length, line spacing, and the adjustment of spaces between groups of letters (tracking) and between pairs of letters (kerning). Typography comes from the Greek words typos, which means “mark, figure” and grapho, which means “I write.” It is basically the discipline of shaping written information; thus it can be applied to anything which has to do with text, including web design. Authors write the text, designers and typographers manage the typography, and users read through it.

228 Solargraphs - How to create 6 month exposures.
Please have a look at Tarja Trygg's www.solargraphy.com for more examples. Much of pinhole photography relates to the use of time and being creative with the light from the sun, similar wonders to that found in astronomy. A 6-month exposure will enable you to image the arc of the sun as it rises or sinks throughout 6 months of the year. As well as this you will get some foreground detail and a camera to look at with awe as a small hole etches its 6-month exposure from your window ledge, garden shed, lamp post, tree etc. Being able to capture a period of time far beyond our own vision is incredible enough, but even more amazing is how simple it is to do. The final camera gives an extreme wide angle of view of 160 degrees.
