1 – 1/2 + 1/3 – 1/4 + = 0. Before explaining how something can be equal to nothing, let me know explain how this bit of mathematics cropped up in the episode. In order to raise funds to rebuild the church, Apu teaches the congregation to card count; a strategy that allows a player to beat the casino at blackjack. NVIDIA Nsight Systems 2019.6 is now available for download. This release expands graphics trace on Windows by adding support for Direct3D 11, WDDM CPU+GPU queues, and OpenGL. On Linux, new features include support for CUDA 10.2, simultaneous CLI sessions, DWARF unwind and capture by hotkey.
Version 1.5 - October 2018 New Features:.PTT using GPIO pin of CM108/CM119 (e.g. DMK URI, RB-USB RIM), Linux only.More efficient error recovery for AX.25 connected mode. Better generation and processing of REJ and SREJ to reduce unnecessary duplicate ' I' frames.New configuration option, ' V20', for listing stations known to not understand AX.25 v2.2. This will speed up connection by going right to SABM and not trying SABME first and failing.New ' NOXID' configuration file option to avoid sending XID command to listed station(s). If other end is a partial v2.2 implementation, which recognizes SABME, but not XID, we would waste a lot of time resending XID many times before giving up.
This is less drastic than the ' V20' option which doesn't even attempt to use v2.2 with listed station(s).New application ' kissutil' for troubleshooting a KISS TNC or interfacing to an application via files.KISS 'Set Hardware' command to report transmit queue length.TCP KISS can now handle multiple concurrent applications.Linux can use serial port for KISS in addition to a pseudo terminal.decodeaprs utility can now accept KISS frames and AX.25 frames as series of two digit hexadecimal numbers.Full Duplex operation. (Put 'FULLDUP ON' in channel section of configuration file.).Time slots for beaconing.Allow single log file with fixed name rather than starting a new one each day.Bugs Fixed:.Possible crash when CDIGIPEAT did not include the optional alias.PACLEN configuration item no longer restricts length of received frames.Strange failures when trying to use multiple KISS client applications over TCP. Only Linux was affected.Under certain conditions, outgoing connected mode data would get stuck in a queue and not be transmitted. This could happen if client application sends a burst of data larger than the 'window' size (MAXFRAME or EMAXFRAME option).Little typographical / spelling errors in messages.Documentation:.New document Bluetooth-KISS-TNC.pdf explaining how to use KISS over Bluetooth.Updates describing cheap SDR frequency inaccuracy and how to compensate for it.Notes:Windows binary distribution now uses gcc (MinGW) version 6.3.0.

I don't have a Mac and probably won't be able to help you. I rely on others, in the user community, for the Mac version support. Version 1.5 - Beta Test 3 - July 2018 Bugs Fixed:.

Version 1.4 - April 2017 New Features:.AX.25 v2.2 connected mode. See chapter 10 of User Guide for details.New client side packet filter to select 'messages' only to stations that have been heard nearby recently. This is now the default if no IS to RF filter is specified.New beacon type, IBEACON, for sending IGate statistics.Expanded debug options so you can understand what is going on with packet filtering.Added new document Successful-APRS-IGate-Operation.pdf with IGate background, configuration, and troubleshooting tips.2400 & 4800 bps PSK modems.
See 2400-4800-PSK-for-APRS-Packet-Radio.pdf in the doc directory for discussion.The top speed of 9600 bps has been increased to 38400. You will need a sound card capable of 96k or 192k samples per second for the higher rates. Radios must also have adequate bandwidth.
See Going-beyond-9600-baud.pdf in the doc directory for more details.Better decoder performance for 9600 and higher especially for low audio sample rate to baud ratios.Generate waypoint sentences for use by AvMap G5 / G6 or other mapping devices or applications. This is the same as version 1.3 beta test with a few minor documentation updates. If you already have 1.3 beta test version, there is no need to replace it with this.Changes since version 1.2. New Features:.
Support for Mac OS X. Many APRStt enhancements including: Morse code and speech responses to to APRStt tone sequences, new 5 digit callsign suffix abbreviation,position ambiguity for latitude and longitude in object reports. APRS Telemetry Toolkit. GPS Tracker beacons are now available for the Windows version. Previously this was only in the Linux version. SATgate mode for IGate. Packets heard directly are delayed before being sentto the Internet Server.
This favors digipeated packets because the originalarrives later and gets dropped if there are duplicates. Added support for hamlib. This provides more flexible options for PTT control. Implemented AGW network protocol 'M' message for sending UNPROTO information without digipeater path. A list of all symbols available can be obtained with the -Scommand line option. Command line option '-a n' to print audio device statistics each n seconds.
Previously this was always each 100 seconds on Linux and not available on Windows.Bugs Fixed:. Fixed several cases where crashes were caused by unexpected packet contents:. When receiving packet with unexpected form of GPS NMEA sentence. When receiving packet with comment of a few hundred characters. Address in path, from Internet server, more than 9 characters. 'INTERNAL ERROR: dlqappend NULL packet pointer.'
When using PASSALL. In Mac OSX version: Assertion failed: (adeva.inbufsizeinbytes = 100 && adeva.inbufsizeinbytes.
