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 readerâ€™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.

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 â€śENABLE_REGISTRATIONâ€ť to â€śfalseâ€ť.

To further secure TT-RSS Reader, uou may also want to change â€śREG_MAX_USERSâ€ť to â€ś1â€ť 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 â€śSingle User Modeâ€ť 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.

868 How Facebook Ships Code Â« FrameThink â€“ Frameworks for Thinking People
Iâ€™m fascinated by the way Facebook operates. Itâ€™s a very unique environment, not easily replicated (nor would their system work for all companies, even if they tried). These are notes gathered from talking with many friends at Facebook about how the company develops and releases software.
Itâ€™s been over six months since I assembled these observations and Iâ€™m sure Facebook has continuously evolved its software development practices in the meantime. So these notes are probably a little bit out-of-date. It also seems like Facebookâ€™s developer-driven culture is coming under greater public scrutiny. So Iâ€™m feeling more comfortable now about releasing these notesâ€¦ HUGE thanks to the many folks who helped put together this view inside of Facebook! Thanks are also due to folks like epriest and fryfrog who have written up corrections and edits.
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" ;)

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.
â€˘ Mirrored glass or plexiglass. Due to the type of paint applied to the reflective coating, inexpensive, craft-store mirror works wonderfully.
â€˘ Latex or other gloves for hand protection.
â€˘ Paint stripper. Most types work fine. For a less toxic product, Citristrip works well.
â€˘ Plastic putty spreader or putty knife.
â€˘ 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.
â€˘ 1â€ť chip brush (or similar brush).
â€˘ Silver paint of choice.
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.

484 Why did so many successful entrepreneurs and startups come out of PayPal? Answered by Insiders
Why did so many successful entrepreneurs and startups come out of PayPal? I long have been fascinated by the extraordinary achievement from the ex-Paypal team and wonder about the reasons behind their success. In the past, mass media tried to answer this question several times but still couldnâ€™t give us a clear answer.
I once asked David Sacks the same question during an event in Los Angeles. He told me the secret is that Paypal has built a â€śscrappyâ€ť culture. No matter what problems they faced, they would find a way to solve them. I kind of got the idea, but was still confused about the execution details.
So when I saw some of the past Paypal employees answering this question on Quora, I was super excited! After all, they should be the only ones who can tell people the inside stories.
Below are some highlights of their answers. *If you want to check out the sources or leave your comments, please go to here and here.
On Talent Management
â€śPeter and Max assembled an unusual critical mass of entrepreneurial talent, primarily due to their ability to recognize young people with extraordinary ability (the median age of *execs* on the S1 filing was 30). But the poor economy allowed us to close an abnormal number of offers, as virtually nobody other than eBay and (in part) google was hiring in 2000-02.â€ť (by Keith Rabois, former Executive Vice President of Paypal)
â€śExtreme Focus (driven by Peter): Peter required that everyone be tasked with exactly one priority. He would refuse to discuss virtually anything else with you except what was currently assigned as your #1 initiative. Even our annual review forms in 2001 required each employee to identify their single most valuable contribution to the company.â€ť (by Keith Rabois, former Executive Vice President of Paypal)
â€śDedication to individual accomplishment: Teams were almost considered socialist institutions. Most great innovations at PayPal were driven by one person who then conscripted others to support, adopt, implement the new idea. If you identified the 8-12 most critical innovations at PayPal (or perhaps even the most important 25), almost every one had a single person inspire it (and often it drive it to implementation). As a result, David enforced an anti-meeting culture where any meeting that included more than 3-4 people was deemed suspect and subject to immediate adjournment if he gauged it inefficient. Our annual review forms in 2002 included a direction to rate the employee on â€śavoids imposing on othersâ€™ time, e.g. scheduling unnecessary meetings.â€ť (by Keith Rabois, former Executive Vice President of Paypal)
â€śRefusal to accept constraints, external or internal:We were expected to pursue our #1 priority with extreme dispatch (NOW) and vigor. To borrow an apt phrase, employees were expected to â€ścome to work every day willing to be fired, to circumvent any order aimed at stopping your dream.â€ť Jeremy Stoppelman has relayed elsewhere the story about an email he sent around criticizing management that he expected to get him fired and instead got him promoted. Peter did not accept no for answer: If you couldnâ€™t solve the problem, someone else would be soon assigned to do it.â€ť (by Keith Rabois, former Executive Vice President of Paypal)
â€śDriven problem solvers: PayPal had a strong bias toward hiring (and promoting / encouraging, as Keith mentions) smart, driven problem solvers, rather than subject matter experts. Very few of the top performers at the company had any prior experience with payments, and many of the best employees had little or no prior background building Internet products. I worked on the fraud analytics team at PayPal, and most of our best people had never before done anything related to fraud detection. If heâ€™d approached things â€śtraditionallyâ€ť, Max would have gone out and hired people who had been building logistic regression models for banks for 20 years but never innovated, and fraud losses would likely have swallowed the company.â€ť (by Mike Greenfield, former Sr. Fraud R&D Scientist of Paypal)
â€śSelf-sufficiency â€“ individuals and small teams were given fairly complex objectives and expected to figure out how to achieve them on their own. If you needed to integrate with an outside vendor, you picked up the phone yourself and called; you didnâ€™t wait for a BD person to become available. You did (the first version of) mockups and wireframes yourself; you didnâ€™t wait for a designer to become available. You wrote (the first draft of) site copy yourself; you didnâ€™t wait for a content writer.â€ť (by Yee Lee, former Product & BU GM of Paypal)
On Culture & Ideology
â€śExtreme bias towards action â€“ early PayPal was simply a really *productive* workplace. This was partly driven by the culture of self-sufficiency. PayPal is and was, after all, a web service; and the company managed to ship prodigious amounts of relatively high-quality web software for a lot of years in a row early on. Yes, we had the usual politics between functional groups, but either individual heroes or small, high-trust teams more often than not found ways to deliver projects on-time.â€ť (by Yee Lee, former Product & BU GM of Paypal)
â€śWillingness to try â€“ even in a data-driven culture, youâ€™ll always run in to folks who either donâ€™t believe you have collected the right supporting data for a given decision or who just arenâ€™t comfortable when data contradicts their gut feeling. In many companies, those individuals would be the death of decision-making. At PayPal, I felt like you could almost always get someone to give it a *try* and then let performance data tell us whether to maintain the decision or rollback.â€ť (by Yee Lee, former Product & BU GM of Paypal)
â€śData-driven decision making â€“ PayPal was filled with smart, opinionated people who were often at logger-heads. The way to win arguments was to bring data to bear. So you never started a sentence like this â€śI feel like itâ€™s a problem that our users canâ€™t do Xâ€ť, instead youâ€™d do your homework first and then come to the table with â€ś35% of our [insert some key metric here] are caused by the lack of X functionalityâ€¦â€ť (by Yee Lee, former Product & BU GM of Paypal)
â€śRadical transparency on metrics: All employees were expected to be facile with the metrics driving the business. Otherwise, how could one expect each employee to make rational calculations and decisions on their own every day? To enforce this norm, almost every all-hands meeting consisted of distributing a printed Excel spreadsheet to the assembled masses and Peter conducting a line by line review of our performance (this is only a modest exaggeration).â€ť (by Keith Rabois, former Executive Vice President of Paypal)
â€śVigorous debate, often via email: Almost every important issue had champions and critics. These were normally resolved not by official edict but by a vigorous debate that could be very intense. Being able to articulate and defend a strategy or product in a succinct, compelling manner with empirical analysis and withstand a withering critique was a key attribute of almost every key contributor. I still recall the trepidation I confronted when I was informed that I needed to defend the feasibility of my favorite â€śbabyâ€ť to Max for the first time.â€ť (by Keith Rabois, former Executive Vice President of Paypal)
â€śExtreme Pressure â€“ PayPal was a very difficult business with many major issues to solve. We were able to see our colleagues work under extreme pressure and hence we learned who we could rely on and trust.â€ť (by Keith Rabois, former Executive Vice President of Paypal)
464 Ksplice Â» Attack of the Cosmic Rays! - System administration and software blog
Itâ€™s a well-documented fact that RAM in modern computers is susceptible to occasional random bit flips due to various sources of noise, most commonly high-energy cosmic rays. By some estimates, you can even expect error rates as high as one error per 4GB of RAM per day! Many servers these days have ECC RAM, which uses extra bits to store error-correcting codes that let them correct most bit errors, but ECC RAM is still fairly rare in desktops, and unheard-of in laptops.
For me, bitflips due to cosmic rays are one of those problems I always assumed happen to â€śother peopleâ€ť. I also assumed that even if I saw random cosmic-ray bitflips, my computer would probably just crash, and Iâ€™d never really be able to tell the difference from some random kernel bug.
A few weeks ago, though, I encountered some bizarre behavior on my desktop, that honestly just didnâ€™t make sense. I spent about half an hour digging to discover what had gone wrong, and eventually determined, conclusively, that my problem was a single undetected flipped bit in RAM. I canâ€™t prove whether the problem was due to cosmic rays, bad RAM, or something else, but in any case, I hope you find this story interesting and informative.

Dans la lignĂ©e de WhoLockMe, Unlocker vous aide Ă dĂ©terminer quel processus ou application vous empĂŞche de supprimer un ou plusieurs fichiers, un cas de figure rencontrĂ© frĂ©quemment. Parfois, il s'agit simplement d'une application utilisant le fichier en question (dans le cas d'un document Word ou Photoshop, par exemple), mais il peut aussi s'agir d'un processus moins Ă©vident Ă dĂ©tecter.
Unlocker propose une interface dans la lignĂ©e de Who Lock Me, mais des possibilitĂ©s plus Ă©tendues. DĂ©tail apprĂ©ciable pour commencer : il rĂ©side dans la barre de notification et se lance automatiquement dĂ¨s l'affichage du message d'erreur (il est Ă©galement possible de l'ouvrir depuis le menu contextuel) Vous pouvez tuer le processus mais aussi Â« dĂ©vĂ©rouiller Â» le fichier sans fermer l'application lorsque c'est possible. Unlocker ne se limite d'ailleurs pas Ă la suppression d'un fichier en cours d'utilisation puisqu'il permet Ă©galement de le dĂ©placer ou renommer. Un mode ligne de commande est disponible en plus de l'interface graphique.
