This will be an introduction to the Elixir programming language and the Erlang concurrency model. And live demos. With Raspberry Pis.
WhatsApp, Delicious, Discord, Nintendo Switch, Pinterest, CouchDB, RabbitMQ, Riak, SimpleDB; all are using Erlang or Elixir.
Do you use a mobile phone or the Internet? 40% of the world's mobile network infrastructure has Erlang at its core. Cisco is shipping 2 million devices per year with Erlang in them. The top 8 Internet service providers and network equipment providers use it in their products. (Those numbers are probably exaggerated, but they look good for this presentation.)
Elixir is a modern, dynamic, functional language leveraging the Erlang VM.
No nutritional value.
MIT licensed.
You get to learn what's cool about one of the new programming languages of the 2010s. And how it goes back to the 1980s.
A demo about the fault-tolerant properties of the Erlang concurrency model.
A demo of a distributed web game made with Phoenix, an Elixir web framework.
Witness a swarm of dozens and even hundreds of Python locusts flooding a cluster of Raspberry Pis as they all play tic-tac-toe. Who will win?
Functional programming. Pattern matching. Meta programming macros. Automated tests. The BEAM. Erlang/OTP. And more...
These people won't be there, but they made this possible. Simon Oulevay will be channeling their spirits during the presentation.

CSS only, bootstrap compatible toggle, checkbox and radio buttons.
There are like thousands of these kind of libraries out there. Why another?
Well... why not?
I have used quite a few different libraries already but I find none of them really fits. Some requires Javascript to work. Some doesn't support all controls I need. Some requires additional tags like label
, i
or span
either nested or next to the inputs. Some just doesn't look nice at all.
So I decided to make my own: Pure CSS, no nonsense additional tags and looks nice (to me)!
I know without additional tags it may not work on some (legacy, outdated) browsers. But hey, who cares? Go back to earth and update your browsers!
Include toggle-checkbox-radio.css
or toggle-checkbox-radio.min.css
to your page:

<link href="path/to/toggle-checkbox-radio.css" rel="stylesheet" />

$8.1M Holloman AFB Contract Awarded to KST
Ka’ala Systems Technology Corp. Awarded Holloman AFB, New Mexico the Base Telecommunications Systems contract for $8,105,000.00 April 2017 – March 2022
Ka’ala Systems Technology (KST) Corp. was awarded Holloman AFB Base Telecommunications Systems (BTS). Award was competitive with NAICS 517110. Services include maintaining the Holloman base and hospital digital/voice switch. KST supports the mission of 49th Communications Squadron at Holloman Air Force Base, New Mexico, by providing highly reliable wired telecommunications and networked voice, video and data services. We perform Operation and Maintenance (O&M) and other services required to ensure the Base Telecommunications System (BTS) is available 24 hours per day, 7 days per week.
The BTS consists of the base telephone system switch, the outside plant (OSP) and inside plant (ISP) systems, network, transmission systems, and all associated equipment which include other systems (e.g., Voice over Internet Protocol (VoIP), etc.). KST operates and maintains all BTS equipment and systems on Holloman AFB in accordance with the Original Equipment Manufacturer (OEM) technical manuals and specifications, Department of Defense (DoD) and US Air Force (AF) policy and regulations, applicable federal, state, and local laws and regulations.
KST is responsible to perform during a crisis situation. In the event of a crisis, additional areas may be identified by the Air Force. KST stands ready and able to base mission changes; major or minor BTS infrastructure modifications; and other support requirements necessary for the BTS to meet mission requirements. Base exercises or actual ongoing base security events frequently interrupt missions. Support requirements may originate from technology changes, hardware and software systems upgrade, reconfigurations, new or additional equipment, local area network (LAN) cable installations and upgrade, and Dial Central Office (DCO) reconfigurations. This includes routing/diversity requirements and any other environmental changes that could impact or alter the BTS.

| LOCK = $(LOG) | HTCondor lock files to synchronize access to various log files. They use the log directory so they are collocated. |
|
| DAEMON_LIST = MASTER, COLLECTOR, NEGOTIATOR, SCHEDD | HTCondor daemons. The WMS Collector services will have the list shown above. The User Collector service uses all but the SCHEDD. The Submit service uses only the SCHEDD. The Frontend service is a client only instance and will have a 'DAEMON_SHUTDOWN = True' to insure no daemons are started accidently. |

| NEGOTIATOR_INTERVAL = 60 NEGOTIATOR_MAX_TIME_PER_SUBMITTER=60 NEGOTIATOR_MAX_TIME_PER_PIESPIN=20 |
Increase negotiation frequency, as new glideins do not trigger a reschedule | |
| PREEMPTION_REQUIREMENTS = False | Prevent preemption | |
| NEGOTIATOR_INFORM_STARTD = False | Negotiator/GCB optimization | |
| NEGOTIATOR.USE_VOMS_ATTRIBUTES = False | Disable checking for VOMS extended attributes (FQAN) | |
| NEGOTIATOR_CONSIDER_PREEMPTION = False | Causes Negotiator to run faster. PREEMPTION_REQUIREMENTS and all condor_startd rank expressions must be False for NEGOTIATOR_CONSIDER_PREEMPTION to be False | |
| COLLECTOR_NAME = wms_service | ||

WMS Collector Submit |
MAX_JOBS_RUNNING = 6000 | Allow up to 6K concurrent running jobs. |
| JOB_START_DELAY = 2 JOB_START_COUNT = 50 |
Start max of 50 jobs every 2 seconds | |
| JOB_STOP_DELAY = 1 JOB_STOP_COUNT = 30 |
Stop 30 jobs every seconds This is needed to prevent glexec overload, when used. |
|
| MAX_CONCURRENT_UPLOADS = 100 MAX_CONCURRENT_DOWNLOADS = 100 |
Raise file transfer limits. No upload limits, since JOB_START_DELAY limits that. But do limit downloads, as they are asyncronous |
|
| APPEND_REQ_VANILLA = (Memory>=1) && (Disk>=1) JOB_DEFAULT_REQUESTMEMORY=1 JOB_DEFAULT_REQUESTDISK=1 |
Prevent checking on ImageSize With 7.8.+, the APPEND_REQ_VANILLA is replaced by the JOB_DEFAULT_REQUESTMEMORY/DISK attributes. Having all 3 attributes defined does not present a problem. |
|
| MAXJOBRETIREMENTTIME = $(HOUR) * 24 * 7 | Prevent preemption | |
| SCHEDD_SEND_VACATE_VIA_TCP = True STARTD_SENDS_ALIVES = True |
GCB optimization | |
| ENABLE_USERLOG_FSYNC = False | Reduce disk IO - paranoid fsyncs are usully not needed | |
| SHADOW.GLEXEC_STARTER = True SHADOW.GLEXEC = /bin/false |
Prepare the Shadow for use with glexec-enabled glideins | |
| MAX_SHADOW_LOG =<PHONE_NUMBER> | Limits size of shadow logs | |
| SEC_ENABLE_MATCH_PASSWORD_AUTHENTICATION = TRUE | Submit service only and only if you have enabled the USE_MATCH_AUTH attribute in the Factory and Frontend configuration files. | |
| SHADOW_WORKLIFE = 0 | This is a workaround to a HTCondor problem
if SEC_ENABLE_MATCH_PASSWORD_AUTHENTICATION = TRUE and HTCondor
version <= 7.5.3 See Condor ticket 1481 |

Atttributes for defining multiple schedds. Effective with Condor 7.7.5+, a JOB_QUEUE_LOG attribute was added. When multiple schedds are used, each additional schedd must specify the unique location for that file. The execute, lock and spool directories for each schedd must be created manually. For more detailed information on this, refer to the Advanced Condor Configuration - Mulitple Schedds document |

SCHEDDJOBS2.SCHEDD_EXPRS = SPOOL_DIR_STRING |
Allows for queries against the schedds directly bypassing the collector
and thus improving performance. Nothing has been implemented at this time to utilize this. Only Factory/WMS Collector communication uses this. |

Space Kitty
I made Space Kitty for my 6 year old daughter who is in kindergarten. The purpose of the app was to help her learn and enjoy math. I plan to add subtraction into the program and eventually, multiplication and division.
Let's Play!
Weather Buddy
I co-created Weather Buddy in order to have my own personalized weather app. It was fun making AJAX calls with the Forecast.io and Google Maps Geocoding APIs.
Check the weather!
ChiStreetArt
Chistreetart was created to catalogue the history of installations and commissioned walls through crowd sourced entries, allowing you to follow the transition of these communal art spaces.

Functions for multi-threaded applications using Libevent.
When using a multi-threaded application in which multiple threads add and delete events from a single event base, Libevent needs to lock its data structures.
Like the memory-management function hooks, all of the threading functions must be set up before an event_base is created if you want the base to use them.
Most programs will either be using Windows threads or Posix threads. You can configure Libevent to use one of these event_use_windows_threads() or event_use_pthreads() respectively. If you're using another threading library, you'll need to configure threading functions manually using evthread_set_lock_callbacks() and evthread_set_condition_callbacks().
| #define EVTHREAD_LOCKTYPE_RECURSIVE 1 |
A recursive lock is one that can be acquired multiple times at once by the same thread.
No other process can allocate the lock until the thread that has been holding it has unlocked it as many times as it locked it.
| EVENT2_EXPORT_SYMBOL void evthread_enable_lock_debugging | ( | void | ) |
Enable debugging wrappers around the current lock callbacks.
If Libevent makes one of several common locking errors, exit with an assertion failure.
If you're going to call this function, you must do so before any locks are allocated.
| EVENT2_EXPORT_SYMBOL int evthread_make_base_notifiable | ( | struct event_base * | base | ) |
Make sure it's safe to tell an event base to wake up from another thread or a signal handler.
You shouldn't need to call this by hand; configuring the base with thread support should be necessary and sufficient.
| EVENT2_EXPORT_SYMBOL int evthread_set_condition_callbacks | ( | const struct evthread_condition_callbacks * | ) |
Sets a group of functions that Libevent should use for condition variables.
For full information on the required callback API, see the documentation for the individual members of evthread_condition_callbacks.
Note that if you're using Windows or the Pthreads threading library, you probably shouldn't call this function; instead, use evthread_use_windows_threads() or evthread_use_pthreads() if you can.
| EVENT2_EXPORT_SYMBOL void evthread_set_id_callback | ( | unsigned long(*)(void) | id_fn | ) |
Sets the function for determining the thread id.

For full information on the required callback API, see the documentation for the individual members of evthread_lock_callbacks.
Note that if you're using Windows or the Pthreads threading library, you probably shouldn't call this function; instead, use evthread_use_windows_threads() or evthread_use_posix_threads() if you can.
| EVENT2_EXPORT_SYMBOL int evthread_use_pthreads | ( | void | ) |
Sets up Libevent for use with Pthreads locking and thread ID functions.

Introduction
Deep generative models are popular nowadays when used for unsupervised learning and for modeling structured outputs. In both cases, the variable that one wants to model contains some structure that cannot be modeled simply via describing its lower order moment or linear correlation. Examples include natural images, natural languages, audio data, etc.
There exists many ways to model the structure of a multivariate distribution, such as
- autoregressive models which assume the joint probability of the random variables can be factorized as a product of distributions,
- energy-based models that define the interaction, or compatibility between the values of the random variables, and
- latent-variable models that assume there exists an unobserved latent variate which can often be thought of as a lower dimensional representation of the data.
We focus on the last category in this monograph, as for the problems that we are going to visit it is a natural assumption to make.
Specifically, the Variational Autoencoders introduced by (Kingma & Welling, 2013) assumes a continuous latent variable model, with a Gaussian prior in the latent space. It is a reasonable assumption to make in many cases, such as for visual imagery: when we move the latent representation of an image in the vicinity of the latent space, it corresponds to changes in shape, color, intensity of light, location of an object, or different kinds of high level semantics of the image.
Frey face manifold from [kingma14]
CelebA faces interpolation from [hou16]
However, training deep continuous latent variable models with nonlinear mapping between the latent code and the observed variable was not so successful only until recently. This is because evaluating the likelihood of a data instance relies on inferring the latent representation, and for non-linear, non-conjugate prior-likelihood pair inference cannot be conducted exactly, or in a computationally tractable way. So we need to approximately infer the latent representation. We will talk more about this in [].
We rely heavily on a family of approximate inference techniques known as the Variational Inference (VI), which is to cast the inference process as an optimization problem by dealing with a lower or upper bound on the original objective. This is different from the sampling-based Markov Chain Monte Carlo (MCMC) methods in many ways. One important aspect is the bias-and-variance trade-off underlying these two classes of algorithms. The MCMC methods often result in high variance estimates but are asymptotically unbiased, while the VI methods have lower variance but due to its choice of (often well-understood and tractable) variational family of distributions are often biased. Even though the variational methods are known to have lower variance, the gradient estimate needed for updating the parameters during training can be very noisy, due to the intractable VI objective that can only be optimized via stochastic gradient methods. We will extend the discussion of this perspective more in [].
The goal of this monograph is to cover the (1) necessary background to understand latent variable models and its training, different views on the well-known variational autoencoders: both (2) from the generative model point of view and (3) from the information theoretic point of view. We will also cover the (4) the intuition of optimizing the objective, (5) training details, and (6) different ways to improve the model, with a hope to help deep learning researchers to better understand the probabilistic aspect of deep generative models and how to use them as a tool.
What's next?

I used to blog more frequently about working at Go Daddy. My silence has not externally imposed, I can assure you. The dearth of entries is the result of working a lot.
When I last discussed my job, I was working with the Social Media Team. I'm still doing that stuff—I do the Fan-Only Content regularly—but my work life mostly revolves around Go Daddy's URL shortener X.CO.
When I first started working on the product, I held URL shortening in very low regard—mostly because of this blog entry by Joshua Schachter. But I've really come around to see the value in them:
I have had a blast working on X.CO, working with some really great people and doing some of the most challenging, innovative development I've ever done. I have learned so much about memcached, parallel programming, jQuery, and multithreading in meeting the needs of a growing user base. (And shutting down the bad guys that want to undermine it all.)

GDP, or Gross Domestic Product, is a measure of aggregate output for an economy's production.
It's a monetary measure, in units such as dollars. In the GDP,
we exclude financial transactions because nothing is produced in a transaction. Instead, it is a movement
of products within the market.
There are two approaches to GDP: the income approach and the expenditure approach.
The income approach has the count income derived from production. The expenditure approach is the count sum
of money spent buying the final goods.
GDP is only measured within the scope of a single year. Note that in order to make it as accurate
as possible, intermediate goods are ignored. Intermediate goods are
goods and services that are purchased for resale or further processing or manufacturing. This is
opposed to final goods, which are goods and services that are purchased for final use by the consumer.
Nonproductive transactions, secondhand sales, and personal productivity do not contribute to production and therefore
are not included in GDP. An example of a nonproductive transaction is buying stock or bonds.
GDP = C(consumption) + Ig(Gross Private Investment) + G(Government Spending) + Xn(Net Exports)
Above is the equation for calculating GDP using the expenditures approach.
The business cycle displays the rise and fall in production output of goods and services within an economy.
During the growth period, inflation increases and unemployment decreases.
During a recession, inflation decreases and unemployment increases.
Unemployment is the state of not utilizing one's skills in the labor force despite being willing and/or able.
There is a difference between not being in the labor force and not being unemployed. If you are not currently looking for a job, despite being able,
then you are not unemployed; instead, you are just not counted as a member of the labor force.
The unemployment rate is the percentage of the workforce that is currently not being employed.
If we relate this back to PPC, unemployment causes inefficiency and therefore hinders the economy from being able to
produce along the frontier. The unemployment rate formula is as follows:
UR = nunemployed ÷ nlabor force × 100%
- Frictional unemployment: includes people who are temporarily between jobs but are actively working or searching for work
- Cyclical unemployment: caused by the recesson phase of the business cycle
- Sructural unemployment: occurs due to changes in the structure of laborial demand
Demand-Pull Inflation describes too many dollars chasing too few goods. It describes inflation on the demand-side. It shows how
aggregate demand outplaces aggregate supply.
Cost-Push Inflation occurs when overall prices increase due to increases in the cost of wages and other resources.
It includes substantial increases in the cost of important goods or servies where no suitable alternative is available.

hpavkey(1) Qualcomm Atheros Open Powerline Toolkit hpavkey(1) NAME hpavkey - HomePlug AV Key Generator SYNOPSIS hpavkey [options] phrase [phrase] [...] DESCRIPTION Convert one or more phrases to encrypted HomePlug AV keys. Phrases are read as command line arguments, converted to either Device Access Keys, Network Membership Keys or Network Identification Keys and printed on stdout. By default, only keys are printed, one key per line, but keys and phrases can both be printed, one pair per line. This program is part of the Qualcomm Atheros Powerline Toolkit. See the AMP man page for an overview and installation instructions. BACKGROUND HomePlug AV technology makes use of special 16-byte binary values, called "keys", for various purposes such as identity and security. Three keys of interest to users are the Device Access Key (DAK), the Network Memership Key (NMK) and Net‐ work Identification Key (NID). Their purpose is described in the HomePlug AV Specification. The HomePlug AV Specification explains how to generate 16-btye binary DAK, NMK and NID values using the SHA-256 algorithm to hash user-supplied ASCII strings, called "pass phrases" in the specification. HomePlug AV compliant pass phrases have from 12 to 64 7-bit ASCII character values in the range 0x20 to 0x7F. In some cases, a specified 8-byte salt is added to the pass phrase before computing the 32-byte hash value. In all cases, the computed hash is then rehashed a specified number of times to produce the final 32-byte value. The HomePlug AV key is the lower 16-bytes of that value. Keys can be any 16-byte binary value but binary values are difficult to remember. HomePlug AV applications, such as the Qualcomm Atheros Windows Device Manager, will ask users for a pass phrase that is converted to a 16-byte binary value using a known hashing algorithm. In principle, no two phrases will product the same key and it would be computationally expensive to derive the pass phrase given the key. Although HomePlug AV software deals directly with the key, users need only remember the pass phrase in order to reproduce the key. OPTIONS -D Uses HomePlug AV rules to compute Device Access Keys (DAK) from pass phrases read from file or stdin. A DAK is 16 bytes expressed as 32 hexadecimal digits. This option over-rides any -M and -N options previously specified on the command line. -e Enforce HomePlug AV length and content rules for phrases. Non-compliant phrases are reported and ignored. Com‐ pliant phrases are 12 to 64 7-bit ASCII characters in the range 0x20 (SP) through 0x7F (DEL). Essentially, this includes any character that can be typed on a standard US or UK keyboard, excluding horizontal tab (HT). Be aware that some command shells intercept and act on special characters instead of passing them to the application. In such cases, you may need to include meta characters. -L level Set security level. The security level is encoded into the NID. Level 0 enables pusbutton pairing. Level 1 dis‐ ables it. This option has no effect unless a NID is computed. -M Uses HomePlug AV rules to compute Network Membership Keys (NMK) from pass phrases read from file or stdin. An NMK is 16 bytes expressed as 32 hexadecimal digits. This option over-rides any -D or -N options previously specified on the command line. -N Uses HomePlug AV rules to compute Network Identification Keys (NID) from pass phrases read from file or stdin. A NID is 7 bytes expressed as 14 hexadecimal digits. This option over-rides any -D or -M options previously specified on the command line. -q Enable quiet mode which, for this application, has no effect. -v Enable verbose mode which, for this application, prints the pass phrase after each key. -?,--help Print program help summary on stdout. This option takes precedence over other options on the command line. -!,--version Print program version information on stdout. This option takes precedence over other options on the command line. Use this option when sending screen dumps to Atheros Technical Support so that they know exactly which version of the Linux Toolkit you are using. ARGUMENTS phrase A pass phrase to be converted to a DAK, NMK or NID. More than one pass phrase can be entered on the command line. Each phrase will be converted to the same type of key and printed in the order specified. Phrases that contain quotes or special delimiters should be enclosed in quotes or apostrophes. By default, phrases can be any length and contain any ASCII chracter except ASCII NUL. Use option -e to enforce HomePlug AV password character and length rules. EXAMPLES The following example prints the ordinary SHA256 key for the phrase, "HomePlugAV0123", entered on the command line. An SHA key is 256 bits or 32 bytes expressed as 64 hexadecimal characters. SHA256 keys are the default output when no key type is specified. SHA256 is a public domain standard, not a HomePlug AV standard. # hpavkey HomePlugAV0123 EA41A2383355FA7CA3B467DF0848A8EB9C41591BE53696C5F45DDAF621784F07 The following example prints the DAK for the phrase, "HomePlugAV0123", entered on the command line. # hpavkey -D HomePlugAV0123 F084B4E8F6069FF1300C9BDB812367FF The following command prints the NMK, instead of the DAK, for the phrase entered on the command line. The ouput is dif‐ ferent because the DAK and NMK are computed differently given the same pass phrase. # hpavkey -M HomePlugAV0123 B59319D7E8157BA001B018669CCEE30D The following command prints the NMK for each phrase entered on the command line. Notice that spaces are legal and sig‐ nificant. Phrases containing spaces must be enclosed in quotes. # hpavkey -M HomePlugAV0123 "The quick brown fox jumped over the lazy dog." B59319D7E8157BA001B018669CCEE30D 56F3C7F539D4F8F5EEC00E63F11A8DEC The following command prints the NMK and pass phrase for each pass phrase entered on the command line because the verbose option is specified. # hpavkey -v -M HomePlugAV0123 "The quick brown fox jumped over the lazy dog." B59319D7E8157BA001B018669CCEE30D HomePlugAV0123 56F3C7F539D4F8F5EEC00E63F11A8DEC The quick brown fox jumped over the lazy dog. hpavkey can be used to compute a key and pass it to another program as an argument. The modpib command shown below will edit file example.pib by replacing the DAK. The -D option expects a hexadecimal key so we can supply one from the phrase "HomePlugAV0123". # modpid -D $(hpavkey -D HomePlugAV0123) example.pib TIPS&TRICKS The following example illustrates an unusual case where the passwords start with dash ("-"). The program assumes that the dash is an option prefix which is incorrect in this case. An error occurs because option -H is illegal. # hpavkey -vM -HomePlugAV -HomePlugAV123 hpavkey: Operation canceled: Option ’H’ has no meaning one solution is to insert a double-dash ("--") on the command line to indicate that no further options appear on the com‐ mand line. We include option -v to display the passwords on output. # hpavkey -vM -- -HomePlugAV -HomePlugAV123 80B74B14E92A739AD41ACDC377451D1B -HomePlugAV 1A46BDE6F75209292FDFC4CCE4D19B4E -HomePlugAV123 See the hpavkeys man page for yet another solution to this problem.

Jeff Bezos Hopes For Regulatory Stability In India, Even As Amazon Does ‘Extremely Well’
by PTIBookmark
E-commerce giant Amazon.com Inc. is doing "extremely well" in India, its founder and Chief Executive Officer Jeff Bezos has said while expressing hope for regulatory stability in the country.
Bezos' remarks came in response to a question on Amazon's concerns over some Indian policies with regard to digitization.
“Regulatory stability is the thing that we would always hope for India. Whatever the regulations are...they are stable and that’s one of the things we’re hoping will now be true. We’ll see,” Bezos, 55, told reporters on the sidelines of his induction into the National Portrait Gallery on Sunday.
He said Amazon was doing very well in India.
Our business in India is doing extremely well. It’s growing very rapidly.Jeff Bezos, CEO, Amazon
He said the head of Amazon’s India operations, Amit Agarwal, with whom he has worked for 20 years, was an extraordinary leader and is doing really well.
The U.S.-based Amazon is pumping in over Rs 4,400 crore (more than $600 million) in its various units in India including marketplace and food retail to provide them more ammunition to compete against arch-rival Flipkart.
Amazon, which is locked in a battle against Flipkart, had registered cumulative losses of over Rs 7,000 crore across various units in 2018-19.
Bezos had committed investment worth $5 billion in the Indian market in 2016.

Fox Hunting
|
An Inexpensive Tape Measure Yagi
Besides the requirement of having a radio that can receive signals from the Fox, the hunter will find a directional antenna to be an essential part of his equipment. The "Tape Measure Antenna" described below is both inexpensive and simple to build. It is made from a 1" metal tape measure and PVC pipe. Parts List: (Drawings may be slightly different than the antenna being built, but the dimensions are the same. Drawing below shows 2 "X" connectors and a "T" connector. By replacing the "T" connector with another "X" connector, a handle can be put on front end to use when nulling a strong signal. The 1/2" pipe in the drawing has been replaced by 3/4" pipe for better stability. Hose clamps may be used on the reflector and director elements if desired.)
36" - 3/4" Schedule 40 PVC pipe
SAFETY: Care should be taken when working with sharp metal edges. Use gloves to prevent cuts and safety glasses to protect your eyes from flying debris. Care should also be used when cutting the metal tape as burrs created by the cuts could inflict injury. STEP 1. Take the 36 PVC tube and cut one piece 11-1/2 long and another piece 7 long. STEP 2. Assemble PVC tube pieces and PVC connectors (Ts and Crosses) as shown above. (No glue is used so antenna may be broken down for storage). STEP 3. Remove the tape from the case. The easiest way to accomplish this is to pull the tape completely out until you see the metal return spring to which it is attached. Simply rotate the tape till the tab of the spring can be slid through the slot in the tape. The spring will recoil into the case and the tape will be ready for trimming.
STEP 4. Measure and cut the four lengths you will need for this antenna (cutting chart below). Use sharp sissors or side cutters to cut the tape.
STEP 5. File and sand any burrs or sharp edges left from cutting the tape. STEP 6. Cover the exposed ends of the tape with plastic electrical tape. Remember: one end of each of the driven element pieces does not get covered. STEP 7. On the untaped ends of the driven element, sand off the paint on the back side of the tape to expose about 1" of bare metal. STEP 8. Center and attach the reflector and director elements to their appropriate locations on the PVC boom (see diagram) using the hose clamps (or alternate method demonstrated in the assembly notes).
STEP 9. Tin the ends of the driven element pieces with solder where you sanded the paint away. Then tin about ¼ of each end of the 6 wire youll be using for the Hairpin match. (You may have to strip the wire if it is jacketed). Also, tin the ends of the coax conductors at this time. STEP 10. Place the driven element pieces on the center cross piece of the PVC boom, securing them with the hose clamps. You should leave about 1 spacing between the ends of the tape. STEP 11. Place the coax center conductor and one end of the "Hairpin" match wife under the hose clamp to one driven element and the braid of the coax and the other end of the "Hairpin" match wire under the hose clamp of the other driven element. STEP 12. Tighten both clamps on the driven elements. STEP 13. Secure the coax to the boom with electrical tape. Your antenna will now function in the receive mode. Now youre ready to check your SWR with an SWR meter or an antenna analyzer if you plan to use it for transmitting. SWR adjustment is achieved by moving the driven elements closer or further away from each other.
ASSEMBLY NOTE: You may use a sheet metal screw and rubber washers to attach the reflector and director elements. This may save you a little bit of money.
The Finished Product Jane, KA0USA, is proud of the performance from the tape measure antenna. She did most of the work herself, including cutting the PVC pipe with a chop saw and tinning the driven elements. The tape measure she used for the elements was purchased for $1.99 at Harbor Freight. She used 6 muffler clamps to attach the elements, rather than using screws to attach them to the PVC fittings. The ends of each element were covered with electrical tape. None of the PVC fittings are glued to the boom. Jane's antenna shows good a front to back ratio and side signal rejection. Signal readings from the Colorado Connection's 145.130 repeater showed an S9+20 db (the highest the meter will show on our rig) with the antenna pointed at it, an S4 reading off the back of the antenna, and S0 (just noise) off the side of the antenna. The original space between the driven elements was 1". We did tweak the SWR just a bit by decreasing the distance between the driven elements by 3/16", but as built, Jane's antenna was okay for use as a transmit antenna as well. The length of the driven element could be shortened just a bit more, but it is quite usable as is. The SWR at 144 MHz was slightly over 1.3:1 at 144 MHz, less than 1.2:1 at 145.5 Megs, and less than 1.7:1 at 148 MHz. Any further tuning will be done by trimming the ends of each of the driven elements 1/16" at a time. No adjustment was made to the 6" hairpin match made from uninsulated #14 solid copper wire. An 8' length of RG-58 was used to connect the antenna to the radio. Tests have shown that the antenna does not function well in windy conditions, as the elements tend to flap in the breeze. However, in calm conditions the antenna works well and is reputed to have a gain of about 7 db. In combination with a suitable attenuator, it makes a formidable T-Hunt antenna. Do not use the antenna to transmit unless you carefully adjust the hairpin and element length to give a low VSWR and an impedance very near 50 ohms. For safety reasons, do not use more than 5-10 watts of power while hand holding this antenna. RF exposure to your body greater than recommended may result. For the same reason, do not point your antenna at anyone while you are transmitting! |


A takeaway line might be this: languages need to evolve to track changing hardware or programmer expectations. To endure, Java has to evolve by adding new features.
The biggest language change in Java 8 is the introduction of lambda expressions—a compact way of passing around behavior. 笔记：在Java 8中，behavior就是指“Code”。behavior的具体表现形式有两种，一种是lambda expression，另一种是method reference，这两种形式的本质就是将Code进行传递。
A lambda expression can be understood as a concise representation of an anonymous function that can be passed around: it doesn't have a name, but it has a list of parameters, a body, a return type, and also possibly a list of exceptions that can be thrown.
That's one big definition; let's break it down:
A lambda expression is composed of parameters, an arrow, and a body.
(Apple a1, Apple a2) -> a1.getWeight().compareTo(a2.getWeight()) ----------------------------------------------------------------------- parameters arrow lambda body
compare
method of a Comparator
— two Apples.
->
separates the list of parameters from the body of the lambda.
The basic syntax of a lambda is:
(parameters) -> expression (parameters) -> { statements; }
注意：下面两个lambda expression是错误的
(Integer i) -> return "Alan" + i;
: 错误，因为return "Alan" + i;
不是expression，而是statement，正确的写法应该加上{}
，即(Integer i) -> {return "Alan" + i;}
(String s) -> {"Iron Man";}
: 错误，是因为"Iron Man"
是expression，而不是statement。正确的写法是：(String s) -> "Iron Man"
，又或者是(String s) -> {return "Iron Man";}
。
So where exactly can you use lambdas? You can use a lambda expression in the context of a functional interface.
In a nutshell, a functional interface is an interface that specifies exactly one abstract method.
What can you do with functional interfaces? Lambda expressions let you provide the implementation of the abstract method of a functional interface directly inline.
If you explore the new Java API, you'll notice that functional interfaces are annotated with @FunctionalInterface
.
This annotation is used to indicate that the interface is intended to be a functional interface.
The compiler will return a meaningful error if you define an interface using the @FunctionalInterface
annotation and it isn't a functional interface.
For example, an error message could be “Multiple non-overriding abstract methods found in interface Foo” to indicate that more than one abstract method is available.
@FunctionalInterface public interface Foo { void firstMethod(); void secondMethod(); }
$ javac Foo.java Foo.java:1: error: Unexpected @FunctionalInterface annotation @FunctionalInterface ^ Foo is not a functional interface multiple non-overriding abstract methods found in interface Foo 1 error
Method references let you reuse existing method definitions and pass them just like lambdas.
Indeed, a method reference lets you create a lambda expression from an existing method implementation.
But by referring to a method name explicitly, your code can gain better readability.
How does it work?
When you need a method reference, the target reference is placed before the delimiter ::
and the name of the method is provided after it.
For example, Apple::getWeight
is a method reference to the method getWeight
defined in the Apple
class.
Remember that no brackets(()
) are needed because you're not actually calling the method.
There are three main kinds of method references:
parseInt
of Integer
, written Integer::parseInt
)length
of a String
, written String::length
)expensiveTransaction
that holds an object of type Transaction
,
which supports an instance method getValue
; you can write expensiveTransaction::getValue
)
Recipes for constructing method references for three different types of lambda expressions
| No. | Lambda | Method reference |
|---|---|---|
| 1 | (args) -> ClassName.staticMethod(args) |
ClassName::staticMethod |
| 2 | (arg0, rest) -> arg0.instanceMethod(rest) |
<ClassName::instanceMethod |
| 3 | (args) -> expr.instanceMethod(args) |
expr::instanceMethod |
You can create a reference to an existing constructor using its name and the keyword new
as follows: ClassName::new
.
It works similarly to a reference to a static method. For example, suppose there's a zero-argument constructor.
// 第一种：lambda expression Supplier<Apple> c1 = () -> new Apple(); // 第二种：Constructor references Supplier<Apple> c1 = Apple::new; Apple a1 = c1.get();
If you have a constructor with signature Apple(Integer weight)
, it fits the signature of the Function
interface, so you can do this,
// 第一种：lambda expression Function<Integer, Apple> c1 = (weight) -> new Apple(weight); // 第二种：Constructor references Function<Integer, Apple> c2 = Apple::new; Apple a2 = c2.apply(110);
If you have a two-argument constructor, Apple(String color, Integer weight)
, it fits the signature of the BiFunction
interface, so you can do this:
// 第一种：lambda expression BiFunction<String, Integer, Apple> c3 = (color, weight) -> new Apple(color, weight); // 第二种：Constructor references BiFunction<String, Integer, Apple> c3 = Apple::new; Apple a3 = c3.apply("green", 110);
It's also possible to create arrays using this method. Here is how you would create a String array: String[]::new
.
import java.util.Arrays; import java.util.function.Function; public class Demo { public static void main(String[] args) { Function<Integer, String[]> func = String[]::new; String[] array = func.apply(3); System.out.println(Arrays.toString(array)); } }
Lambda和Method Reference都是属于Behavior Parameterization的范围。
int i = 100;
其中，int
是Type，是装数据的“容器”，而100是Value，是真正的“数据”。这就表达了Type与Value之间的关系：Type是“容器”，Value是“数据”。
将Value装载到Type这个容器当中： Type <-- Value
那么，把Type和Value的概念应用到Behavior Parameterization上来说，Lambda和Method Reference表示的只是Value，而Functional Interface表示的是Type。
Behavior Parameterization是将Code（Behavior）进行参数化，而Type Parameterization（Generics，泛型）是将Type进行参数化。
Lambda = anonymous functions Method Reference = named functions

Man Reaches Down Pants, Holds His Penis Then Dumps Semen On Woman By The Sidewalk
by Veronica ElankovanTap to listen to this article instead: 🔊 Listen to Post
This is just disgusting!
A man in West Jawa, Indonesia was caught on video throwing his semen on several women. The man aims for women who are standing at by the sidewalk whilst waiting for a taxi or bus.
Source: Youtube
The video went viral after a victim’s husband uploaded a video, photo and police report of the attack on social media. In the video, it can be seen that the man threw some sort of fluid towards the victim.
 A few seconds later he threw his semen onto the victim. YUCK! 🤮
Head of Criminal Investigation of the Tasikmalaya Headquarters, Assistant Commissioner Sudangantoro said,
“The suspect dons a leather jacket and rides a scooter. He looks like he might be in his 20s, based on the victim’s statement.”
As of now, the police is currently on a lookout for the pervert, and they hope to arrest him as soon as possible before he finds his next victim. We also hope that the police will arrest him asap too!
