It can push you over your phones data cap if you use it too regularly. English Hindi Dictionary Free isnt as powerful or accurate as Googles service, but it does everything offline. That makes it easier to turn your smartphone into a pocket translator. English Hindi Dictionary Free stores its entire dictionary on your gadget, so downloading the whole thing takes a little while. You have the choice of stashing words on your SD card or your phones internal memory, which is convenient. As you type words in English, it brings up best guesses to save you a couple of taps. It has a pretty large dictionary that was able to find Hindi words for even very obscure English vocabulary terms. To save time, you can add words to your favorites or browse your history of searched words for common words, too. Though this app brags about working offline, it features ads on every page. Ads can still use some of your phones data if youre not careful. Still, the app itself is faster than a Web search. Since this app works offline, the data use is minimal as long as you download the dictionary over Wi Fi. Thats great for people using it during travel who cant afford to deal with restrictive data caps or overseas roaming charges.

I have created a simple HTML form and Perl script to display an Allstar nodes status in a html page. It also optionally allows any valid Allstar command to be entered for the given node. I call it. 'lsnodes' and there is a version that works in both command mode and as a web page either locally or. This is not intended to be in competition with any other display program out there but rather to be. 'lsnodes' An Asterisk Allstar Node Status and Control HTML viewer. Description. I have created a simple HTML form and Perl script to display an Allstar nodes status. Preparing Preparing and Running Make. To prepare to use make, you must write a file called the makefile that describes the relationships among files in your program. This is a book for anyone who uses Asterisk. Asterisk is an open source, converged telephony platform, which is designed primarily to run on Linux. Perl and html/css knowledge can modify to their own requirements. The html form queries the node number and optionally a command and sends them to a Perl script on. This script takes the optional Allstar command and executes it on the server. This information is refreshed at a one minute. The refresh rate as well as what is displayed and how it is display on the returned page. Perl script. If you follow the instructions on how to install this it should work but I make no guarantees.
This was a learning experience for me and writing it in Perl makes text manipulation. Certainly using jquery/ajax/php as. My intent was something that worked for me and. I. present it here for others to use, modify, etc. If anyone has ideas about. I will implement. I have tested this code but the only good test is. It plays well in Firefox and Chrome. Windows Explorer is problematic. I don't use it and. I suspect most others don't either so I made no attempt to make it work better. Consider this beta code and if you have problems please let me know. I. find it to be very useful and I hope you do also. Installation involves several steps and you must make several changes to the system that. Linux, like how to edit and save files and get. If you are not sure of something I would be glad to answer. These instruction are for the Acid release in Centos. If you have already installed httpd to use the web server on your Allstar. If you are not sure if you have httpd installed. If it returns files or nothing then you have httpd installed and you. If you get. a no such file or directory error then you do not have it installed. Installation Steps. First we download and install the httpd from the repository. Answer yes to the question to install and if all goes well it should tell. We have to edit one line in the httpd. Find the line that defines the server name near the end of the file and. If you don't have a dns name for your server. IP address otherwise put your domain name there. If your host doesn't have a registered DNS name, enter its IP address here. You will have to access it by its address anyway, and this will make. Server. Name 1. 27. Now start the server, you should get no errors. Now lets make it start at boot - . Runlevels 2,3,4,5 should be ON. Which should look like this - . PHP Installation. If you have not installed the Allmon requirements or you do not. PHP installed on your Allstar server then you will need to install it. To test if it is. If this returns the version like below then you can skip the PHP installation steps. If. it returns an error then complete the PHP installation steps. The build. date and version does not need to be the same. PHP 5. 1. 6 (cli) (built: Dec 1. Copyright (c) 1. 99. The PHP Group. Zend Engine v. Copyright (c) 1. 99. Zend Technologies. PHP Installation Steps. Once installed it should show the version as above. Download lsnodes files. Download the tarball and copy to to /var/www/html and extract. This will create. Download the tarball. Allstar computer. This should create a directory under html called lsnodes and untar the files there. This Perl script lsnodes_web relies on the Allstar database to display. If you are already using Allmon. The file which creates/accesses the database is astdb. This file creates a file called astdb. It is updated by a crontab entry. If you have Allmon installed the cron entry would look like this - . This would update the astdb. AM daily. The 0. 3 0. In case you don't have Allmon installed (no /var/www/html/allmon directory) I am including the. To implement this. Here we select the directory where the astdb. The time is completely random and once a day. The database needs to be initially created if you have not installed Allmon. To execute this file manually just type the full path and name - . This will create the astdb. DO NOT access this file. If you need to. access it manually to see a change you made that is. If you are not using the default Allmon astdb. Perl script. There is a note above the line there. The stock line in lsnodes_web looks like this and would be used if you have Allmon installed. Specify the location of the Allstar database. Allmon installed change it to this - . Specify the location of the Allstar database. Now we need to change the sudoers execution rights for Asterisk. Edit sudoers and add the three lines below starting with. Cmnd_Alias ASTERISK. Spelling and case is important! Use your editor of choice. Cmnd_Alias PROCESSES = /bin/nice, /bin/kill, /usr/bin/kill, /usr/bin/killall. Cmnd_Alias ASTERISK = /usr/sbin/asterisk, /usr/bin/curl. User_Alias ADMINS = apache. ADMINS ALL = NOPASSWD: ASTERISK. Further down in the file the following line should be commented out. Add a '#' before it as shown below. Defaults requiretty. Now save the file. IMPORTANT! - the sudoers file must be returned to. Edit the httpd config file using vi, nano, or your favorite editor. If you want to change your http port for Allstar edit. Shown below with default value. Listen: Allows you to bind Apache to specific IP addresses and/or. See also the # directive. Change this to Listen on specific IP addresses as shown below to. Apache from glomming onto all bound IP addresses (0. Listen 1. 2. 3. 4. Further down in the file. Make sure the cgi- bin definition looks like this - . Directory "/var/www/cgi- bin">. Allow.

A prediction (Latinpræ- , "before," and dicere, "to say"), or forecast, is a statement about an uncertainevent. It is often, but not always, based upon experience or knowledge. There is no universal agreement about the exact difference between the two terms; different authors and disciplines ascribe different connotations. Contrast with estimation.)Although guaranteed accurate information about the future is in many cases impossible, prediction can be useful to assist in making plans about possible developments; Howard H. Stevenson writes that prediction in business ".. Important and hard."[1]Judgement- based prediction[edit]In a non- statistical sense, the term "prediction" is often used to refer to an informed guess or opinion. A prediction of this kind might be informed by a predicting person's Abductive reasoning, Inductive reasoning, Deductive reasoning and experience and may be of useful if the predicting person is a knowledgeable person in the field. The Delphi method is a technique for eliciting such expert- judgement- based predictions in a controlled way. This type of prediction might be perceived as consistent with statistical techniques in the sense that, at minimum, the "data" being used is the predicting expert's cognitive experiences forming an intuitive"probability curve."Statistics[edit]In statistics, prediction is a part of statistical inference. One particular approach to such inference is known as predictive inference, but the prediction can be undertaken within any of the several approaches to statistical inference. Indeed, one possible description of statistics is that it provides a means of transferring knowledge about a sample of a population to the whole population, and to other related populations, which is not necessarily the same as prediction over time. When information is transferred across time, often to specific points in time, the process is known as forecasting.[3] Forecasting usually requires time series methods, while prediction is often performed on cross- sectional data. Statistical techniques used for prediction include regression analysis and its various sub- categories such as linear regression, generalized linear models (logistic regression, Poisson regression, Probit regression), etc. Fixed match,fixed matches,vip ticket,soccer predictions,football predictions,betting tips,football tips,soccer tips,football betting tips,football prediction sites.

In case of forecasting, autoregressive moving average models and vector autoregression models can be utilized. When these and/or related, generalized set of regression or machine learning methods are deployed in commercial usage, the field is known as predictive analytics.[4]In many applications, such as time series analysis, it is possible to estimate the models that generate the observations. If models can be expressed as transfer functions or in terms of state- space parameters then smoothed, filtered and predicted data estimates can be calculated.[5] If the underlying generating models are linear then a minimum- variance Kalman filter and a minimum- variance smoother may be used to recover data of interest from noisy measurements. These techniques rely on one- step- ahead predictors (which minimise the variance of the prediction error). When the generating models are nonlinear then stepwise linearizations may be applied within Extended Kalman Filter and smoother recursions. However, in nonlinear cases, optimum minimum- variance performance guarantees no longer apply.[6]To use regression analysis for prediction, data are collected on the variable that is to be predicted, called the dependent variable or response variable, and on one or more variables whose values are hypothesized to influence it, called independent variables or explanatory variables. A functional form, often linear, is hypothesized for the postulated causal relationship, and the parameters of the function are estimated from the data—that is, are chosen so as to optimize is some way the fit of the function, thus parameterized, to the data. That is the estimation step. For the prediction step, explanatory variable values that are deemed relevant to future (or current but not yet observed) values of the dependent variable are input to the parameterized function to generate predictions for the dependent variable.[7]Prediction in science[edit]NASA's 2. In science, a prediction is a rigorous, often quantitative, statement, forecasting what would happen under specific conditions; for example, if an apple fell from a tree it would be attracted towards the center of the earth by gravity with a specified and constant acceleration. The scientific method is built on testing statements that are logical consequences of scientific theories. This is done through repeatable experiments or observational studies. A scientific theory which is contradicted by observations and evidence will be rejected. New theories that generate many new predictions can more easily be supported or falsified (see predictive power). Notions that make no testable predictions are usually considered not to be part of science (protoscience or nescience) until testable predictions can be made. Mathematical equations and models, and computer models, are frequently used to describe the past and future behaviour of a process within the boundaries of that model. In some cases the probability of an outcome, rather than a specific outcome, can be predicted, for example in much of quantum physics. In microprocessors, branch prediction permits avoidance of pipeline emptying at branch instructions. In engineering, possible failure modes are predicted and avoided by correcting the mechanism causing the failure. Accurate prediction and forecasting are very difficult in some areas, such as natural disasters, pandemics, demography, population dynamics and meteorology. For example, it is possible to predict the occurrence of solar cycles, but their exact timing and magnitude is much more difficult (see picture to right). Scientific hypothesis and prediction[edit]Established science makes useful predictions which are often extremely reliable and accurate; for example, eclipses are routinely predicted. New theories make predictions which allow them to be disproved by reality. For example, predicting the structure of crystals at the atomic level is a current research challenge.[8] In the early 2. The existence of this absolute frame was deemed necessary for consistency with the established idea that the speed of light is constant. The famous Michelson- Morley experiment demonstrated that predictions deduced from this concept were not borne out in reality, thus disproving the theory of an absolute frame of reference. The special theory of relativity was proposed by Einstein as an explanation for the seeming inconsistency between the constancy of the speed of light and the non- existence of a special, preferred or absolute frame of reference. Albert Einstein's theory of general relativity could not easily be tested as it did not produce any effects observable on a terrestrial scale. However, the theory predicted that large masses such as stars would bend light, in contradiction to accepted theory; this was observed in a 1. Finance[edit]Mathematical models of stock market behaviour (and economic behaviour in general) are also unreliable in predicting future behaviour. Among other reasons, this is because economic events may span several years, and the world is changing over a similar time frame, thus invalidating the relevance of past observations to the present.

Byte Buffers and Non- Heap Memory. Byte Buffers and Non- Heap Memory Most Java programs spend their time working with objects on the JVM heap. A few programs, however, need to do something different. Perhaps. they're exchanging data with a program written in C. Or they need to manage. Or. maybe they need efficient random access to files. For all these programs. Byte. Buffer is an alternative to traditional. Java objects. Prologue: The Organization of Objects Let's start by comparing two class definitions. The one on the left. Byte Buffers and Non-Heap Memory. Most Java programs spend their time working with objects on the JVM heap, using getter and setter methods to retrieve or change the. · I have a Java application that I run from a console which in turn exec's another Java process. I want to get a thread/heap dump of that child process. On Unix I could. We all have seen the dreaded 'Blue screens of death.' These screens actually create dump files on the PC, as a.dmp file, as to where a problem in a certain program. Is it safe to delete system error memory dump files after running a disk clean up? Also what are system error memory dump files? The HSQLDB jar package is located in the /lib directory and contains several components and programs. Different commands are used to run each program. It is not unusual that a SAP job/program can be terminated on memory error. In my experience, I have seen SAP job/program terminations on following memory errors: TSV. In computing, a core dump (in Unix parlance), memory dump, or system dump consists of the recorded state of the working memory of a computer program at a specific. C++, the one on the right is Java. They both declare the same. C++ class describes the layout of a block. Java class doesn't. TCP_Header. unsigned short source. Port. unsigned short dest. Port. unsigned int seq. Num. unsigned int ack. Num. unsigned short flags. Size. unsigned short checksum. Ptr. char data[1]. Tcp. Header. private short source. Port. private short dest. Port. private int seq. Num. private int ack. Num. private short flags. Size. private short checksum. Ptr. private byte[] data. C++, like C before it, is a systems programming language. That means that. it will be used to directly access objects like network protocol buffers. One way. to do this is with pointer arithmetic and casts, but that's error- prone. Instead, C (and C++) allows you to use a structure or class definition as. You can take any pointer, cast. Num; the compiler does the pointer arithmetic. In a real C++ program, of course, you'd define such structures using the. I got to experience this first- hand as processors moved from 1. Java is better than C++ in this respect. However, Java comes with its own data access caveats. Foremost among them is. Code like obj. seq. Num does not translate to pointer arithmetic. These operations are responsible for finding the particular field. JVM. By giving the JVM the flexibility to arrange its objects' fields as it sees fit. For. example, on a machine that only allows access to memory in 3. JVM is allowed. to re- arrange those fields and combine them into a contiguous 3. Byte. Buffer The fact that Java objects may be laid out differently than defined is. Since a Java class cannot be used as a view. JVM has decided to shuffle. However, there are situations where it would be nice to have this. Prior. to JDK 1. 4, Java programmers had limited options: they could read data into a. Or they could wrap that. Data. Input. Stream and get. The Byte. Buffer class arrived in JDK 1. A Byte. Buffer can be. Most of the time, you'll want to. Byte. Buffer buf = Byte. Buffer. wrap(data). Short(0, (short)0x. Int(2, 0x. 12. 34. Long(8, 0x. 11. 22. L). for (int ii = 0 ; ii < data. System. console(). When working with a Byte. Buffer, it's important to keep. In the code, above, we wrote a two- byte value. System. console(). Int(0)); The best way to ensure that you're always using the correct indices is. Taking the TCP header as an example. Tcp. Header. Wrapper. Byte. Buffer buf. Tcp. Header. Wrapper(byte[] data). Byte. Buffer. wrap(data). Source. Port(). return buf. Short(0). public void set. Source. Port(short value). Short(0, value). public short get. Dest. Port(). return buf. Short(2). // and so on Slicing a Byte. Buffer Continuing with the TCP example, let's consider the actual content of. TCP packet, an arbitrary length array of bytes that follows the fixed. The C++ version defines data, a. This is an idiomatic usage of C- style arrays. In Java, of course, arrays are. There are two ways that you can extract an arbitrary byte array from a buffer. The first is to use the get() method to copy bytes into. Data(). buf. position(get. Data. Offset()). int size = buf. However, this is often the wrong approach, because you don't really. Output. Stream or treat it as a sub- structure. In. these cases, it's better to create a new buffer that represents a subsection of. Byte. Buffer get. Data. As. Buffer(). Data. Offset()). return buf. If you looked closely, you may have noticed that the last two code snippets. I passed. in an explicit offset. Most Byte. Buffer methods have two. I find little use for the latter. Something else to remember: when you call slice() the new. Any changes that. If you don't want that to. Beware Endianness In Gulliver's Travels, the two societies of Lilliputians break their. Computer architectures suffer from a similar strife, based on the. Little- endian” machines, such as the PDP- 1. Big- endian” machines, like. Motorola 6. 80. 00 and Sun SPARC, put the high- order bytes first. Java manages data in Big- Endian form. However, most Java programs run on. Intel processors, which are Little- Endian. This can cause a lot of problems. Java program and a C or C++. For example, here's a C program that. On a Linux system, you can use the od command to dump the file's. When you write a naive Java program to retrieve that data, you see the. File. Input. Stream in = new File. Input. Stream("/tmp/example. Exception("unable to read file contents"). Byte. Buffer buf = Byte. Buffer. wrap(data). System. console(). Int(0)); If you want to see the correct data, you must explicitly tell the buffer. Little- Endian. buf. Byte. Order. LITTLE_ENDIAN). System. console(). Int(0)); But here's a question: how do you know that the data is Little- Endian? One. common solution is to start files with a “magic number” that. For example, UTF- 1. FEFF: a reader can look at those two bytes, and select. Big- Endian conversion if they're in the order 0x. FE0x. FF, or Little- Endian if they're in the order. An alternative is to specify the ordering, and require writers to follow. For example, the set of protocols collectively known. TCP/IP all use Big- Endian ordering, while the GIF graphics file format. Little- Endian. Interlude: A Short Tour of Virtual Memory. Byte. Buffer isn't just used to retrieve structured data. It also allows you to create and work with. Java heap, including memory- mapped files. This latter. feature is a great way to work with large amounts of structured data, as. A program running on a modern operating system thinks that it has a large. Windows and Linux, 8 terabytes or more for x. Behind the scenes, the. I've written elsewhere about how the JVM uses virtual memory: it assigns space for the Java heap. JVM itself, and. memory- mapped files (primarily JAR files). On Linux, the program pmap. In thinking about virtual memory, there are two concepts that every. The second. is easiest to explain: it's the total amount of memory that your program might. The potential commit charge for an entire system is the sum of. RAM and swap space, and no program can exceed this. It doesn't matter how big. G of RAM, and 2. G of swap, you can. G of in- memory data; there's no place to store it. In practice, no one program can reach that maximum commit charge either. If you try to allocate memory that would exceed the. Out. Of. Memory. Error. The second concept, resident set size (RSS), refers to how many of your. RAM. If a page isn't. RAM, then it needs to be read from disk — faulted into RAM. The important thing to know. RSS is that you have very little control over it. The operating. system tries to minimize the number of system- wide page faults, typically. RSS on the basis of time and access frequency: pages that are. RSS is one reason that “full” garbage. GC compacts the heap it will. Swing programmers know this, and. GC before being minimized, in order to prevent page. One final concept: pages in the resident set can be “dirty,”. A dirty page must be. By comparison, a clean (unmodified) page may simply be discarded; it will be. If you can guarantee that a page will never. |
