And be sure to visit the beautiful, new, SEARCHABLE Python documentation page from the busy geeks at Python. If you prefer learning from a good Python book, try this one. After you acquire basic knowledge in Python, you can move onto some other great books. The Python Cookbook, 2nd Ed.by Alex Martelli, Anna Ravenscroft and David Ascher, which provides recipes for common tasks you might like to accomplish using Python on your computer.
For many people, this is the best way to learn code, by studying examples contained in programs that do useful work. Learning Python, 4th Ed.by Mark Lutz, commonly considered the most thorough introduction to the language for beginners, now out in a new 3rd edition that covers Python 2. 5 and looks ahead to Python 3. Python Essential Reference, 4th Ed. This is the newest of the Python books and probably the best all-around Python book, but newbies may find it overly terse.
Beazley wastes no words and has a tight, crisp writing style. If you are already familiar with basic programming concepts, but are new to Python, Beazley is your man. In my most recent book, Rapture For The Geeks When AI Outsmarts IQI argue that Python should be declared the Official Language of The Singularity. If you agree, cast your vote by leaving a comment below.
Rapture For The Geeks also includes an Emily Dickinson poem translated into the Python programming language by Python experts Alex Martelli and Anna Ravenscroft see page 196 of Rapture. Some visitors install newer versions of Python from the ActiveState downloads page. You can install more than one version and use different versions as you please. However, starting with Python 3. 0, many commands are new and different. For example, the print command for Python 3.
0 and following goes like this print Hello World. For this How-To, I recommend that you play it safe and install the version recommended by ActiveState. Most of the tutorials for newbies are still written for older versions of Python. But, hey, it s a living breathing language, so if you like it, install and learn the newest version. This post dates to the days of Windows XP, but I update it every year or so. org site and select more tutorials. There are plenty of good ones.
Release Date Dec. There are now newer bugfix releases of Python 3. 7 that supersede 3. 6 and Python 3. 8 is now the latest feature release of Python 3.

Notable performance improvements in many areas. Please see What s New In Python 3. 7 for more information. Get the latest releases of 3. Airspy is a plug-and-play device and does not require any particular driver installation on Windows Vista, 7, 8, 8. You just plug Airspy and Windows will download and install the right driver for you. Installation on Windows Vista, 7, 8, 8. There are exceptions where the original configuration of the PC does not allow the automatic installation of this class of devices.
In such case, a driver should be installed manually with the following procedure. Download and unzip the WinUSB Compatibility Driver Open the device manager and select Airspy Select Update Driver then Browse My Computer to the inf file. Please don t. Installation on Windows Server or Windows XP. Airspy was designed by the same people who developed the SDR software so it s the obvious choice for running Airspy and leverage all its powerful features.
First, go to the download page and get a copy. Then run SDRSharp. exe and select the AIRSPY front-end. Then next step is the gain configuration. As depicted in this screen shot, there are many gain modes. Sensitivity Linearity Free Custom. The Linearity mode is the one you want to start with. The following fine tuning procedure ensures you have the maximum SNR on the signal of interest while preserving the dynamic range.
Start with the minimum gain Increase the gain until the natural noise floor rises by about 5dB Check that increasing the gain no longer increase SNR. If not, increase the gain by an extra notch. Fine tune to maximize the SNR the blue bar graph on the right. In any case, you should make sure the RF noise floor just overrides the quantization noise floor of the ADC, but no more.
Using the SpyVerter. Airspy has an option to cover the HF bands The SpyVerter. They are not supported. It is a low loss, high dynamic range, ruggedized up-converter based on a switching design the same kind that is used in very high end HF rigs like the Elecraft K3. The default software settings allow Airspy to power the SpyVerter via the bias-tee functionality so no extra power supply is needed.
It offers HF coverage starting near DC up to 35MHz where it overlaps with the standard VHF-L of the Airspy alone. It is recommended to use the Linearity gain mode in HF. To verify your setup, plug a HF antenna and tune the AM broadcast band. You should get a view like this one. Using the SPY Server for Remote SDR Operation. Just connect the IF Output of the SpyVerter to the RF Input of the Airspy via the supplied barrel adapter.
Since revision 1553, we offer a new utility for the Airspy series to convert a Raspberry Pi, an Odroid, or just your regular Windows or Linux PC into a fully featured SDR server. The SPY Server allows you to connect many SDR clients to the same Airspy or RTL-SDR device over the network. When only one client is connected, full control center frequency, gain is granted.
When there are more than one client connected, the center frequency of the device and the RF gain are locked. The default settings allow using the server in the LAN with optimal latency. The Full IQ option allows streaming the entire spectrum from the device to the SDR client SDR. The bandwidth savings allows usage over the Internet, but still requires high speed connection. The SPY Server comes with a standard configuration file that allows you using Airspy or RTL-SDR directly without an upconverter.
If you have many devices in the same server, you can have multiple configuration files and pass the right one as parameter to the executable. If the SpyVerter is used, the following parameters should be set in spyserver. Initial Center Frequency initial_frequency 7100000. Minimum Tunable Frequency Comment if using the device default minimum_frequency 0. If the network bandwidth is not sufficient to handle the traffic, uncheck the Full IQ option and the server will only stream the FFT display data and reduced IQ data that it necessary for decoding one VFO.
Converter Offset Set to -120000000 to enable the SpyVerter offset converter_offset -120000000. Maximum Tunable Frequency Comment if using the device default maximum_frequency 35000000. Bias-Tee For AirspyOne only Useful for LNA s and SpyVerter enable_bias_tee 1. Running on Windows. Edit the configuration file if necessary and double click on spyserver.
Running on x86 Linux. First, make sure you are have the latest version of libairspy installed. Extract spyserver_linux_x86 and spyserver. config from the standard zip, chmod and run. unzip sdrsharp-86. zip chmod a x spyserver_linux_x86. spyserver_linux_x86 spyserver. Running on ARM Linux Raspberry Pi or Odroid. Download and extract the standard ARM package and run. tgz tar xzf spyserver-arm32. spyserver spyserver.
Linux Troubleshooting. What could go wrong in the Linux world. Well, many things see the GPL sections 15 and 16. Here s a list of the most obvious ones people reported so far. The program runs, but cannot acquire the device The user mode driver is probaby not up to date. Try compiling the libairspy libairspyhf from source. Sometimes using sudo makes things just magically work. 21 not found Try installing GCC 5. Using the ADSB decoder in embedded ARM boards. You need firmware version 1.
0 rc7 or newer to use Airspy as an ADSB receiver. com airspy firmware releases READ the instructions before doing anything. The latest Raspbian distros come with a new default CPU governor that is not suitable for sustained high performance operation. The CPU will start at a very high frequency 1200MHzget very hot, then throttle back to a very low frequency 600 MHz. The governor will keep swinging back and forth between these two extremes and the USB controller will drop whole packets, which could affect both the number of decodes and the MLAT timing.
Raspberry Pi 3 Performance Tuning. The following settings will force the performance governor at a much more acceptable CPU frequency for sustained operation without causing excessive heat and without sacrificing the performance of the decodes. sudo home pi airspy_adsb -l 30005 beast -x -m 12. This will run all the decoding in one core using 5 signal phases instead of 10, which requires half of the CPU usage, while still being very accurate for MLAT. Additionally, we recommend to put these lines in etc rc.
echo performance sys devices system cpu cpu0 cpufreq scaling_governor echo performance sys devices system cpu cpu1 cpufreq scaling_governor echo performance sys devices system cpu cpu2 cpufreq scaling_governor echo performance sys devices system cpu cpu3 cpufreq scaling_governor. Then append these lines to boot config. Lastly, you can also disable the FIQ Fix that limits the number of USB interrupts.
Less USB interrupts will create more latency when polling the samples out of the USB hardware with the risk of missing more buffers. To disable the FIQ Fixyou can add the following parameter to the line in boot cmdline. Standard setup non FlightAware. The whole process for setting up a high performance ADSB receiver has been simplified. For the Raspberry Pi 2 or 3, Odroid or Pine64 boards, you can use the following commands. airspy_adsb -l 30005 beast -l 47806 asavr -p -m 12 -x. FlightAware Integration.
The easiest way to integrate Airspy into an existing FlightAware PiAware is described here. If you don t need all the details, you can just use this neat installation script by FlightAware member wiedehopf. This script works for FlightAware SD Card images. Once you have your decoder up and running, you can use any aircraft tracking software that supports the Beast or AVR formats.
Virtual Radar Sever. Here s an example configuration for Virtual Radar Server. Plane Plotter. For Plane Plotter, you can use this configuration. The effects of oversampling and decimation. tgz tar xzf airspy_adsb-linux-arm. The decimation option allows you to trade some of the instantaneous bandwidth to get more bit resolution, and hence, lower quantization noise. The basic rule of thumb is 3dB every time you divide the bandwidth by two.
To further leverage the effects of the decimation, you can also readjust the gain using the same procedure described above. So, decimation by two gives you 3dB, decimation by 4 gives you 6dB, by 8 gives 9dB and so on. A slight saturation of the ADC gives you more SNR after decimation. So basically, when you use a higher decimation rate, adjust for higher gain and vice versa.
The Bias-Tee option 4. In some cases, one may need a very low noise figure. For example, some satellite communication systems require a front end with a noise figure as low as 0. In such case, using an external preamplifier near the antenna system can improve the overall operation. The Bias-Tee option allows powering such a preamplifier directly from Airspy by injecting DC at 4. Of course, such a preamp should have its own biasing system to extract the DC and inject the amplified RF signals.
Another use case one can imagine is to switch between antennas using that bias signal or even power down-converters for higher bands OR up-converters for LF and HF, like the SpyVerter mentioned above. The current budget is limited to 50mAso that s enough to run most of the modern MMICs. Starting from June 2016, Airspy R2 units are calibrated in the factory up to. The procedure to recalibrate a unit is as follows. This calibration is written in a different memory location than the one used for the firmware, so upgrading the firmware won t delete it unless you do it by yourself.
Open the calibration tool AirspyCalibrate. Note that this procedure requires firmware version 1. exeClear the correction, Reset the device unplug plug againInject a known and accurate signal, Set its exact frequency in the tool, Click on CalibrateReset the device. 0-RC9 or better. Troubleshooting PC performance problems. We created a set of command line utilities to help troubleshooting the performance problems. If very high MLAT reliability is required, the following switche should be applied to the decoder.

The newest version of ProtonVPN for Windows supports Split Tunneling, allowing you to decide which applications should use the VPN encrypted tunnel. Release Notes for Windows app v1. Posted on February 5th, 2019 by Richie Koch in Articles News. There are also more profile options and OpenVPN ports. Split Tunneling. With Split Tunneling, you can protect your private data with VPN encryption and still access public networks at the same time. By activating Split Tunneling, we will route all of your Internet traffic through the encrypted VPN tunnel except for the apps and the destination IP addresses you select.
To activate Split Tunneling, navigate to Settings. By excluding non-sensitive data from VPN encryption, you will reduce latency and be able to access foreign and locally geo-blocked content at the same time. and then select the Advanced tab. Once you turn Split Tunneling on, you will be able to select which apps and IP addresses to exclude from the encrypted VPN tunnel.
Inverse Split Tunneling. For more details, see our Support article. Inverse Split Tunneling is, as the name suggests, the opposite of Split Tunneling. Instead of selecting which apps and IP addresses to exclude from the blanket VPN encryption, Inverse Split Tunneling lets you choose which apps have their Internet traffic encrypted in the VPN tunnel. All other traffic will be excluded from the VPN tunnel. You can now write longer names for your Profiles up to 25 charactersand select new options for profile colors.
Increased Profile customization and syncing. Profiles are also now saved to accounts rather than devices. This means that your saved profiles will be automatically accessible on other devices that run Windows when you sign in to the ProtonVPN app. Additional OpenVPN ports. Beginning with version 1. 7, the Windows app will randomly select an OpenVPN port and it has a greater selection of ports.
Not only does this provide better load balancing leading to better performanceit also offers better protection against VPN blocking. 7 of our Windows app, click here. We re excited about these new features in the latest version of ProtonVPN for Windows. Please join us on Facebook, Twitter, and Reddit, and let us know you what think.
Now, if the first port selected is blocked, the app will automatically fall back to the next randomly selected port. To download version 1. You can get a free ProtonVPN account here. Follow us on social media to stay up to date on the latest ProtonVPN releases Twitter Facebook Reddit. To get a free ProtonMail encrypted email account, visit protonmail. How about Split Tunneling for MacOS X. This VPN is good but it lacks the great prices you would normally see in other VPN providers, i suggest subscribing to FastestVPN if you re looking for the best budget VPN.
The split tunneling feature for MacOS is considered to be developed in the future. Hello, Bobby. Unfortunately, we cannot provide a fixed ETA at the moment. If you follow us on our social media channels, you can get all the news and updates. I d love to have port-forwarding as a feature in general. Unfortunately, port-forwarding is not supported on ProtonVPN at this moment.
Please consider it. We will consider adding this feature in the upcoming period, but we cannot give you any specific time-frame for that to happen. This includes Protonmail Bridge listening on 127. With this new version I can no longer connect to any services running on 127. I cannot connect to any local 127. 1 SSH tunnels either. Disconnecting and existing the software is not enough, I have to kill the Iqoption ib service process in task manager to restore connectivity to 127.
It does not matter if I use an include or exclude model for split tunneling even if I exclude 127. 1or have no splitting tunnel configuration at all, 127. Since I rely on Protonmail Bridge I ve had to stop using Protonvpn. 1 remains inaccessible. Anyone else seeing the same issue. We would be glad to help you out. Will you consider adding SSH SSL Tunneling in order to better get around ISP blocking and throttling. This would require port-forwarding which we do not support at the moment, but we will consider it for our further developments.
Richie, I would be very interested to hear ProtonVPN s perspective on the advantages of using the VPN as it relates to new threats posed by 5G technology. That s a great suggestion, thank you. It will be passed on to our team. Interesting addition. Love the split tum nelinggreat featurewell implemented easy to use and setup thanks it really adds o the value. I have two questions 1. Iqoption ib there any plans to allow two separate tunnels to different VPN servers on a per-application basis.
Is there a way to do the above on Linux with some OpenVPN magic. At the moment, we do not have any plans but we will consider implementing this feature in the future. Regarding your second question, unfortunately, that is not possible. Can t wait for the Linux version. The native client is under development, but we cannot provide any specific date for its release yet. com is an trading website for stocks and cryptocurrency.
by admin August 24, 2020. Alternatively, if you are randomly redirected once or twice, the site you were visiting may have triggered the redirect. It is a legitimate website but if you are constantly redirected to it, you may have adware installed on your computer. If you are dealing with adware, you likely have noticed other symptoms as well, such as an increase in advertisements, random redirects and constant browsing disruptions.
But it will not directly harm the computer as that is not its main purpose. Nonetheless, it s doubtful you will want adware installed on your device for long, as it will noticeably affect how you browse. Fortunately, adware is not a particularly dangerous infection, and mainly focuses on exposing you to as many ads as possible. The sooner you remove iqoption.
com adware, the better. Adware usually installs sneakily, via iqoption ib bundles so it would not be surprising if you are not able to recall installing it. If you continue reading, we will explain how this works and how you can avoid installing the offers in the future. How does adware spread. Adware is mostly installed by users themselves, albeit without them even realizing it. Less serious infections like adware come attached to free software as additional iqoption ib, which are permitted to install alongside the freeware.
They are preselected to install alongside automatically and are hidden from users during freeware installation. But they are optional, meaning you can prevent their installation, and quite easily to tell the truth. When installing freeware, opt for Advanced Custom settings instead of Default when given the option.
Advanced will make the offers visible, as well as give you the option of deselecting all offers. Simply uncheck the boxes and you can continue the installation. For future reference, keep in mind that most free programs will have these additional offers. Deselecting them initially is easy, compared to having to uninstall pesky infections later on.
And while some of those offers may seem useful, software bundling is quite frowned upon, meaning programs that use it should not be installed. If you continue to install these free offers, your computer will quickly fill up with junk programs that are difficult to get rid of later on. It should be mentioned that you could get randomly redirected to sites like iqoption.
com when visiting high-risk sites and clicking on something. Many free programs often come together with additional offers, which usually include adware, browser hijackers and potentially unwanted programs PUPs. Many sites use low-quality ads to make revenue, and this causes users to get redirected to all kinds of questionable websites.
What does the adware do. Having adblocker enabled when visiting potentially high-risk websites can help avoid annoying ads, pop-ups and redirects. As soon as adware installs, it attaches itself to popular browsers like Internet Explorer, Google Chrome and Mozilla Firefox. Once it s attached to a browser, it will constantly try to redirect you to sites like iqoption. The redirects happen completely randomly, which greatly affects the quality of your browsing.
In addition to redirects to iqoption. com Removal Explained. com, you may also be redirected to other websites and shown questionable ads. We don t recommend interacting with a site if you get randomly redirected because you could end up on dangerous page promoting malware or scams. If you end up on a site that claims there is something wrong with your computer, do not interact with it.
If you do call one of those numbers, you would be connected to tech-support scammers who would try to force you to pay hundreds of dollars for non-existent services. It s merely a tech-support scam that wants you to either call a scammer number or to install a highly questionable program. We should also mention that adware keeps track of what sites you visit, what you search for, your IP address, etc.
com removal. While it isn t personal information, it s doubtful you want to be tracked by adware. In order to delete iqoption. Adware can be a persistent infection to deal with, and incorrectly uninstalling it could allow it to recover. com adware, we strongly suggest using anti-spyware software. However, you can uninstall iqoption. com manually, and we will provide instructions below this article to help you. Download Removal Tool to scan for iqoption. com To scan for iqoption.
