Multi- tasking operating systems executes processes in a time slice fashion sharing the processing resources base on their current privilege. Privileges are not constant and elevate if they have not received an execution allocation in the processor after a given time. This is to ensure that all processes get executed regardless of priority although a process can get squeezed out of the time allocation alltogether if the system is overloaded. Higher priority processes may get more time allocated on the processor than a lower priority process but it is likely that the lower process will get some processor allocation. Many system process which manage the system environment execute at an elevated priority in order to guarentee that they get executed. User processes can have their priority elevated using the nice command. Nice values have a range from - 2. Beware that if the priority is elevated higer than a system process, the behavior of the system may be compromised. Modify process scheduling priority. Lower scheduling priority (runs slower and less likely to slow you down.). Default for "nice - n" is 1. Show default for any process: nice executable. Shows nice value to be used if run.

Every release, the Fedora Design team creates a new default wallpaper for Fedora. In addition to the default wallpaper, the Fedora repositories also contain a set of extra Supplemental Wallpapers for each release. These older wallpapers are not installed by default, but are easily installed from the Fedora Repositories. If you have just set up a fresh install of Fedora, and want to expand your choices for your desktop wallpaper, the older Fedora wallpapers are a great choice. This post lists out the older wallpapers available in the Fedora repositories, and how to install them on your current Fedora install. On Fedora Workstation, after you have installed your desired pack, they will show up in the Wallpapers tab in the Background chooser in the Settings. Note: If you are using a desktop environment other than the default for Fedora Workstation (GNOME), there are also packages tailored to some of the more popular alternative desktops.

Page Anti- Diversity Screed Circulating Internally at Google [Updated]Update 8/5/1. ET: Google’s new Vice President of Diversity, Integrity & Governance Danielle Brown has issued her own memo to Google employees in response to the now- viral memo, “Google’s Ideological Echo Chamber.” Brown’s statement, obtained by Motherboard, can be found in full at the end of this article. A software engineer’s 1. Google’s diversity initiatives is going viral inside the company, being shared on an internal meme network and Google+. The document’s existence was first reported by Motherboard, and Gizmodo has obtained it in full. In the memo, which is the personal opinion of a male Google employee and is titled “Google’s Ideological Echo Chamber,” the author argues that women are underrepresented in tech not because they face bias and discrimination in the workplace, but because of inherent psychological differences between men and women. We need to stop assuming that gender gaps imply sexism,” he writes, going on to argue that Google’s educational programs for young women may be misguided. The post comes as Google battles a wage discrimination investigation by the US Department of Labor, which has found that Google routinely pays women less than men in comparable roles. Gizmodo has reached out to Google for comment on the memo and how the company is addressing employee concerns regarding its content. We will update this article if we hear back. The text of the post is reproduced in full below, with some minor formatting modifications. Two charts and several hyperlinks are also omitted. Reply to public response and misrepresentation. I value diversity and inclusion, am not denying that sexism exists, and don’t endorse using stereotypes. When addressing the gap in representation in the population, we need to look at population level differences in distributions. If we can’t have an honest discussion about this, then we can never truly solve the problem. Psychological safety is built on mutual respect and acceptance, but unfortunately our culture of shaming and misrepresentation is disrespectful and unaccepting of anyone outside its echo chamber. Despite what the public response seems to have been, I’ve gotten many personal messages from fellow Googlers expressing their gratitude for bringing up these very important issues which they agree with but would never have the courage to say or defend because of our shaming culture and the possibility of being fired. This needs to change. TL: DRGoogle’s political bias has equated the freedom from offense with psychological safety, but shaming into silence is the antithesis of psychological safety. This silencing has created an ideological echo chamber where some ideas are too sacred to be honestly discussed. The lack of discussion fosters the most extreme and authoritarian elements of this ideology. Extreme: all disparities in representation are due to oppression. Authoritarian: we should discriminate to correct for this oppression. Differences in distributions of traits between men and women may in part explain why we don’t have 5. Discrimination to reach equal representation is unfair, divisive, and bad for business. Background [1]People generally have good intentions, but we all have biases which are invisible to us. Thankfully, open and honest discussion with those who disagree can highlight our blind spots and help us grow, which is why I wrote this document.[2] Google has several biases and honest discussion about these biases is being silenced by the dominant ideology. What follows is by no means the complete story, but it’s a perspective that desperately needs to be told at Google. Google’s biases. At Google, we talk so much about unconscious bias as it applies to race and gender, but we rarely discuss our moral biases. Political orientation is actually a result of deep moral preferences and thus biases. Considering that the overwhelming majority of the social sciences, media, and Google lean left, we should critically examine these prejudices. Left Biases. Compassion for the weak. Disparities are due to injustices. Humans are inherently cooperative. Change is good (unstable) Open. Idealist. Right Biases. Respect for the strong/authority. Disparities are natural and just. Humans are inherently competitive. Change is dangerous (stable)Closed. Pragmatic. Neither side is 1. A company too far to the right may be slow to react, overly hierarchical, and untrusting of others. In contrast, a company too far to the left will constantly be changing (deprecating much loved services), over diversify its interests (ignoring or being ashamed of its core business), and overly trust its employees and competitors. Only facts and reason can shed light on these biases, but when it comes to diversity and inclusion, Google’s left bias has created a politically correct monoculture that maintains its hold by shaming dissenters into silence. This silence removes any checks against encroaching extremist and authoritarian policies. For the rest of this document, I’ll concentrate on the extreme stance that all differences in outcome are due to differential treatment and the authoritarian element that’s required to actually discriminate to create equal representation. Possible non- bias causes of the gender gap in tech [3]At Google, we’re regularly told that implicit (unconscious) and explicit biases are holding women back in tech and leadership. Of course, men and women experience bias, tech, and the workplace differently and we should be cognizant of this, but it’s far from the whole story. On average, men and women biologically differ in many ways. These differences aren’t just socially constructed because: They’re universal across human cultures. They often have clear biological causes and links to prenatal testosterone. Biological males that were castrated at birth and raised as females often still identify and act like males. The underlying traits are highly heritable. They’re exactly what we would predict from an evolutionary psychology perspective. Note, I’m not saying that all men differ from women in the following ways or that these differences are “just.” I’m simply stating that the distribution of preferences and abilities of men and women differ in part due to biological causes and that these differences may explain why we don’t see equal representation of women in tech and leadership. Many of these differences are small and there’s significant overlap between men and women, so you can’t say anything about an individual given these population level distributions. Personality differences. Women, on average, have more: Openness directed towards feelings and aesthetics rather than ideas. Women generally also have a stronger interest in people rather than things, relative to men (also interpreted as empathizing vs. These two differences in part explain why women relatively prefer jobs in social or artistic areas. More men may like coding because it requires systemizing and even within SWEs, comparatively more women work on front end, which deals with both people and aesthetics. Extraversion expressed as gregariousness rather than assertiveness. Also, higher agreeableness. This leads to women generally having a harder time negotiating salary, asking for raises, speaking up, and leading. Note that these are just average differences and there’s overlap between men and women, but this is seen solely as a women’s issue. This leads to exclusory programs like Stretch and swaths of men without support. Neuroticism (higher anxiety, lower stress tolerance). This may contribute to the higher levels of anxiety women report on Googlegeist and to the lower number of women in high stress jobs. Note that contrary to what a social constructionist would argue, research suggests that “greater nation- level gender equality leads to psychological dissimilarity in men’s and women’s personality traits.” Because as “society becomes more prosperous and more egalitarian, innate dispositional differences between men and women have more space to develop and the gap that exists between men and women in their personality becomes wider.” We need to stop assuming that gender gaps imply sexism. Men’s higher drive for status. We always ask why we don’t see women in top leadership positions, but we never ask why we see so many men in these jobs. These positions often require long, stressful hours that may not be worth it if you want a balanced and fulfilling life.
Libro - Wikipedia, la enciclopedia libre. Un libro (del latínliber, libri) es una obra impresa, manuscrita o pintada en una serie de hojas de papel, pergamino, vitela u otro material, unidas por un lado (es decir, encuadernadas) y protegidas con tapas, también llamadas cubiertas. Un libro puede tratar sobre cualquier tema. Según la definición de la Unesco,[1] un libro debe poseer 2. También se llama "libro" a una obra de gran extensión publicada en varias unidades independientes, llamados "tomos" o "volúmenes". Otras veces se llama también "libro" a cada una de las partes de una obra, aunque físicamente se publiquen todas en un mismo volumen (ejemplo: Libros de la Biblia). Hoy en día, no obstante, esta definición no queda circunscrita al mundo impreso o de los soportes físicos, dada la aparición y auge de los nuevos formatos documentales y especialmente de la World Wide Web. El libro digital o libro electrónico, conocido como e- book, está viendo incrementado su uso en el mundo del libro y en la práctica profesional bibliotecaria y documental. Además, el libro también puede encontrarse en formato audio, en cuyo caso se denomina audiolibro. Desde los orígenes, la humanidad ha tenido que hacer frente a una cuestión fundamental: la forma de preservar y transmitir su cultura, es decir, sus creencias y conocimientos, tanto en el espacio como en el tiempo. El planteamiento de esta cuestión supone: por un lado, determinar la forma de garantizar la integridad intelectual del contenido de la obra y la conservación del soporte en el que fue plasmada, y por otro, encontrar el medio por el cual se mantendrá inalterada la intención o finalidad para la cual se concibió. Los orígenes de la historia del libro se remontan a las primeras manifestaciones pictóricas de nuestros antepasados, la pintura rupestre del hombre del paleolítico. Con un simbolismo, posiblemente cargado de significados mágicos, estas pinturas muestran animales, cacerías y otras escenas cotidianas del entorno natural del hombre antiguo, que trataba de dominar las fuerzas adversas de la naturaleza capturando su esencia mediante su representación.

Comunicación oral y formas rudimentarias[editar]Las señales gestuales fueron la primera forma de expresar y transmitir mensajes. La palabra hablada es la manera más antigua de contar historias. Mediante fórmulas de valor mnemotécnico[2] se estructuraban narraciones, que pasaban de generación en generación como valiosa herencia cultural de los más diversos grupos humanos. Dichas reglas mnemotécnicas ayudaban tanto a la memorización como a la difusión de los relatos. Es el caso de los poemas homéricos, que han merecido valiosos estudios sobre el particular. Posiblemente, gran parte de las tradiciones y leyendas han tenido semejante inicio. Esta transmisión oral tenía el inconveniente de los «ruidos» que deformaban el mensaje. La mayoría de las veces era el narrador (rapsoda, aeda, juglar) quien en función de sus intereses la deformaba de una u otra forma. La escritura[editar]Cuando los sistemas de escritura fueron inventados en las antiguas civilizaciones, el hombre utilizó diversos soportes de escritura: tablillas de arcilla, ostracon, placas de hueso o marfil, tablas de madera, papiros, tablillas enceradas, planchas de plomo, pieles curtidas, etc. La escritura fue el resultado de un proceso lento de evolución con diversos pasos: imágenes que reproducían objetos cotidianos (pictografía); representación mediante símbolos (ideografía); y la reproducción de sílabas y letras. Los más antiguos vestigios de escritura se encuentran, hacia finales del IV milenio a. C., en el Antiguo Egipto, con jeroglíficos, y la antigua Mesopotamia, mediante signos cuneiformes (escritura cuneiforme; utilizaban una varilla con sección triangular, que al hendir en placas de arcilla, dejaba una marca en forma de cuña). La usaron los sumerios, acadios, asirios, hititas, persas, babilonios etc. La escritura egipcia, que perduró más de tres milenios, mediante jeroglíficos, representaba ideas abstractas, objetos, palabras, sílabas, letras y números. Evolucionó en las escrituras hierática y demótica. Otros pueblos, como los hititas y los aztecas también tuvieron tipos propios de escritura. La escritura china más antigua que se conoce son 5. C. en el yacimiento de Xiaotun, en la provincia de Henan. Pero los primeros libros reconocibles de China corresponden al siglo VI a. C., los jiance o jiandu, rollos de finas tiras de bambú o madera grabados con tinta indeleble y atados con cordel. Estos textos servían principalmente a causas institucionales , era la obra de funcionarios civiles o militares.[3]Desde Confucio en adelante (5. C.) los libros se convirtieron en importantes instrumentos de aprendizaje, se escribieron tratados de filosofía, medicina, astronomía y cartografía. En el período de los reinos combatientes (4. C.) La seda se usó mucho como soporte para escribir. La tela era ligera, resistente al clima húmedo, absorbía bien la tinta y proporcionaba al texto un fondo blanco, sin embargo era mucho más cara que el bambú, es por esto que en ocasiones se hacía una copia en bambú antes de grabarse en seda los textos importantes. La invención del papel según la tradición china, se atribuye a un eunuco de la corte imperial llamado Cai Lin en el 1. C. Usando nuevos ingredientes (trapos viejos, cáñamo, corteza de árbol y redes de pescar) creó un método de fabricación de papel muy similar al que se usa hoy en día. Pero el papel tardó cientos de años en reemplazar al bambú y la seda, fue hasta finales del siglo II d. C. que la corte imperial lo usó en cantidades importantes. Esta innovación no se propagó fuera de China hasta el 6. C. aproximadamente, y alcanzó Europa a través de España hasta el siglo XII. A mediados del siglo VIII los chinos inventaron la impresión xilográfica, o el grabado en madera, y la necesidad de reproducir un gran número de textos e imágenes budistas, calendarios, manuales de adivinación y diccionarios promovió una rápida y temprana propagación de la xilografía. El primer libro impreso chino que se ha encontrado es el Sutra del diamante del 8. C. Los impresores chinos crearon los tipos móviles hacia el siglo XI, el escritor chino Ch'en Kua (1. Mengshi Pitan), según el escritor el herrero Jen. Tsung de la dinastía de los Song del norte entre 1. También se le atribuye la creación de una mesa giratoria para guardar los caracteres, esta técnica se llamaba tipografía tablearia. Hacia el 1. 30. 0 Wang- Tcheng, un técnico agrónomo, emplazó la arcilla por madera de azufaifo, que era mucho más dura. Pero este avance no revolucionó la imprenta hasta el punto que lo hizo Gutenberg en Europa 4. A diferencia de las lenguas europeas, el chino escrito requiere miles de caracteres únicos, lo que hace mucho más eficaz los bloques de madera individuales que los enormes conjuntos de tipos reutilizables. En contraste con el declive de las artes de los escribas en occidente en los siglos que siguieron a la creación de la imprenta de tipos móviles, la caligrafía china conservó su prestigio, era un arte. No obstante, a finales del siglo XV, China había producido más libros que el resto del mundo junto. Los árabes aprendieron la técnica para fabricar papel de sus contactos con China en el siglo VIII, y este se introdujo en Europa en el siglo XII a través de la España musulmana.[3]La obra xilográfica más antigua encontrada hasta nuestros días es el Dharani Sutra de Corea, datado en el 7. C., aunque no se sabe quién fue el inventor de la xilografía los chinos y coreanos fueron los que impulsaron la impresión xilográfica, principalmente para editar textos religiosos. El budismo chino y coreano fue el vehículo que trasmitió la xilografía a Japón. Pero Corea realizó muchos otros avances que revolucionaron la manera de imprimir y en consecuencia el libro. Entre 1. 23. 4 y 1. Gwanghwa, debido a la invasión mongol, no disponían de madera dura fue entonces que imprimieron 2. Go geum sang jeong ye mun con caracteres móviles metálicos. La obra del año 1. Más tarde el rey Taejong puso en funcionamiento un taller que contribuía a la difusión de la escritura y en 1. Jujaso, donde se fabricaban caracteres móviles de imprenta, realizó la primera fundición de tipos móviles en bronce. The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The crust is underlain by the mantle. The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust. The boundary between the crust and mantle is conventionally placed at the Mohorovi? The crust occupies less than 1% of Earth's volume.[1]. The oceanic crust of the sheet is different from its continental crust. The oceanic crust is 5 km (3 mi) to 1. The continental crust is typically from 3. Some of these less dense rocks, such as granite, are common in the continental crust but rare to absent in the oceanic crust. Partly by analogy to what is known about the Moon, Earth is considered to have differentiated from an aggregate of planetesimals into its core, mantle and crust within about 1. The primordial crust was very thin and was probably recycled by much more vigorous plate tectonics and destroyed by significant asteroid impacts, which were much more common in the early stages of the solar system. Earth has probably always had some form of basaltic crust, but the age of the oldest oceanic crust today is only about 2. In contrast, the bulk of the continental crust is much older. The oldest continental crustal rocks on Earth have ages in the range from about 3. Narryer Gneiss Terrane in Western Australia, in the Acasta Gneiss in the Northwest Territories on the Canadian Shield, and on other cratonic regions such as those on the Fennoscandian Shield. Some zircon with age as great as 4. Narryer Gneiss Terrane. A theoretical protoplanet named "Theia" is thought to have collided with the forming Earth, and part of the material ejected into space by the collision accreted to form the Moon. As the Moon formed, the outer part of it is thought to have been molten, a “lunar magma ocean.” Plagioclase feldspar crystallized in large amounts from this magma ocean and floated toward the surface. The cumulate rocks form much of the crust. The upper part of the crust probably averages about 8. The underlying mantle is denser and olivine- rich. The thickness of the crust ranges between about 2. Crust on the far side of the Moon averages about 1. Estimates of average thickness fall in the range from about 5. Most of this plagioclase- rich crust formed shortly after formation of the moon, between about 4. Perhaps 1. 0% or less of the crust consists of igneous rock added after the formation of the initial plagioclase- rich material. The best- characterized and most voluminous of these later additions are the mare basalts formed between about 3. Minor volcanism continued after 3. There is no evidence of plate tectonics.

As the number of servers that I am responsible for managing increases, it becomes more difficult to ensure that they are all patched up to date. As most of the machines I manage are SBS boxes I thought that it would be nice to put something together which behaves in much the same way as the SBS generated e- mail alerts. So, the result is a script which sends e- mail notifications to a specified address and gives details of which patches are available to be installed. The administrator can choose which of the four patch levels will trigger an e- mail alert (Critical, Important, Moderate & Low). If there are no outstanding patches at the appropriate alert levels to be installed then the script will quit without sending an e- mail. The script is then run as a scheduled task every evening and I can quickly see if I have anything to action. The report includes links to the relevant KB articles and further information made available by Microsoft. The script only takes a couple of minutes to setup as there are only six settings at the top of the file…Setting any of the following to 1 will generate trigger alerts for that particular update severity: Alert. Critical. Alert. Low. Email. From – Specifies the e- mail address the report will be sent from. Email. To – Specifies the e- mail address to send the reports to. As shown above I have been running with Alert. Critical/Alert. Important set to 1 and the other two set to 0. So, if you want to receive email alerts all you need to do is download this Zip file, extract the contents to a folder on your server and then edit the variables at the top of the script. To perform a test run go into a command prompt and change directory to the location where you extracted the script and run: cscript winupdates. With any luck you should get an e- mail soon after with the results. If you find that it is not generating you an e- mail as expected, one reason may be that there are no patches available to install. Bear in mind that not all items from Windows update will appear. For example “Internet Explorer 7″ is not a patch and therefore will not be listed. Running the script interactively as above will take a few moments while Windows Update(or WSUS if you have it installed) are checked for new updates. Once you have completed a successful test you can go ahead and setup a scheduled task. Assuming an installation directory of “c: \scripts” the scheduled task command should look something like this: C: \WINDOWS\system. Also worth a mention that I have used this on standard(non- sbs) Windows servers and it works well. Perhaps if enough people use this script, it will actually save as much time as it took to make it, but I doubt it. Video News - CNNChat with us in Facebook Messenger.

Version 1. 5. 2. 1 contains smaller but significant updates to the markers and iso- surface capabilities, and adds the ability to do structure mapping with 1, 2, 3 and N mouse pick points. I also made some small interface changes to ensure the "Information" text box is always displayed. Many thanks for the useful feedback I received from many users. New functionality. Mapped structural planes can be added with 1, 2, 3 or N points and their orientations are displayed on a polar plot (equal angle stereo- net). The created discs can be saved as a DXF- file, or the disc plane parameters can be saved as a CSV text file, which can then be loaded again as a "Mapping" file. This functionality is further discussed in the "Mapping with mouse picking" section below. Meshes can be split on any picked polygon, where the selected polygon plane is used as the splitting plane. This functionality works well in conjunction with the discs discussed in Point 1, as a disc can be created with three pick points, and the surface then used to split a mesh triangulation into separate layers. More options were added to the iso- surface creation parameters that determines the outcome: Resolution: This selection determines the number of sub- division "blocks", which in turn regulates the resolution of the created surface. A higher resolution will take longer to solve. Search radius: This selection determines the search distance from the centre of each "block" when interpolating an inverse distance value. Artefacts result if the search distance is too short, and the surface could be over- smoothed when the distance is too long. Longer search distances results in substantially longer calculation times.

When loading files, a "Coordinates" pop- up box is always displayed where the coordinates system can be changed.

The saved coordinate system is selected with "Save => Save in original coordinate system" and "Save => Save in new coordinate system". Changes. The information text box is now placed separately and visible in all modes (file meshes, markers and mapping). Measurement and picking information is thus now visible in all "modes". Download Microsoft Excel Object Library For Vb6 DatasetDetermining the boundaries for iso- surface creation were previously done from the scene boundaries. If a mesh triangulation was loaded, the iso- surface boundaries would thus have included the triangulation and resulted in poor resolution around the actual data points. The new version calculates the boundaries for the iso- surfaces from the data boundaries only - as intuitively expected. Interaction with the buttons around the iso- surface functionality were changed after use in various studies. These are small changes that determine when buttons become available and when values are reset. These changes should further improve the flow of iso- surface creation. When loading "Marker" data, the default column "0" is now the Z- coordinate. Loaded values are thus coloured on the Z- coordinate by default, and other values follows as columns "1", "2", etc. Bug fixes. GEM4. D attempts to automatically accommodate any coordinate system. Download Microsoft Excel Object Library For Vb6 Data ControlThis is reasonably involved to manage correctly under any circumstance, and coding changes were made to the logic for the latest version. These changes could have introduced bugs, so please let me know when anything suspect occurs. Iso- surface search radius. The input data is typically in the form of an irregular grid, such as stress results, mapping results, logging data, observations etc. When the check box of (3) is pressed, a regular grid is generated, with the resolution based on the resolution value in the drop- down text- box below the slider, and values interpolated to the regular grid with the Shepard Method (inverse distance). These interpolated values are based on the selected search radius in the search radius drop- down text- box below the slider. An iso- surface is then created based on the interpolated values of the regular grid. ![]() If the search radius is very short, only regular grid values close to actual data points will pick up values and the other points left blank. Visually, this results in a blocky iso- surface close to the irregular data points and looks artificial. When the search radius is too long, values are smoothed over too many values, and the visual outcome could be less accurate than for a shorter search radius. Selecting the correct search radius is thus very important, and GEM4. D attempts to select the appropriate value based on the data set. It is still valuable to choose different values, observed the impact on the iso- surface, and decide on the most appropriate value for the data set. Mapping with mouse picking. Mapping discs in three dimensions are an valuable way to understand the potential impact of discontinuities on underground excavations and slope walls. As creating these discs in mine design software are typically a bit lengthy, I added 4 options to GEM4. D to do this in a few mouse clicks. Only the location is picked in the scene; the dip, dip direction and trace length are thus requested in a pop- up form. Pick with 2 points. Two points are picked and they determine the trace length and strike (thus also dip direction), and only the dip is requested by the pop- up form. The trace value now determines how far the disc will extend beyond the picked points. Pick with 3 points Three points are picked and they fully define the plane of the disc. The disc is centered around the average value of the picked coordinates. The disc radius is the distance from the average value and the picked point furthest away, plus the value selected in the trace text- box. Pick with N points. Picked by N- points allows the gradual building of a plane by many points. One way to solve the plane is to build an average plane through all the selected points, but I found that does not work well in practice. The system I decided to use is simple and works well for my applications, let me know if you feel otherwise. The disc orientation is determined by the first two and last selected points only, but the other selected points do determine the disc size. The way I normally use this, is to selected the plane strike with the first two points, next click at the extremities of the plane without worrying much about the orientation, and use the last pick to fix the dip direction. This system also allows many "last picks" until the plane visually fit the available data well. Visual Basic - Wikipedia. This article is about the Visual Basic language shipping with Microsoft Visual Studio 6. For the Visual Basic language shipping with Microsoft Visual Studio . NET or later, see Visual Basic . NET. Visual Basic is a third- generationevent- driven programming language and integrated development environment (IDE) from Microsoft for its Component Object Model (COM) programming model first released in 1. Microsoft intended Visual Basic to be relatively easy to learn and use.[1][2] Visual Basic was derived from BASIC, a user- friendly programming language designed for beginners, and it enables the rapid application development (RAD) of graphical user interface (GUI) applications, access to databases using Data Access Objects, Remote Data Objects, or Active. X Data Objects, and creation of Active. X controls and objects. A programmer can create an application using the components provided by the Visual Basic program itself. Over time the community of programmers developed third- party components.[3][4][5][6][7] Programs written in Visual Basic can also use the Windows API, which requires external function declarations. The final release was version 6 in 1. Visual Basic). On April 8, 2. Microsoft stopped supporting Visual Basic 6. IDE. The Microsoft Visual Basic team still maintains compatibility for Visual Basic 6. Windows Vista, Windows Server 2. R2, Windows 7, Windows 8, Windows 8. Windows Server 2. Windows 1. 0 through its "It Just Works" program.[8] In 2. Visual Basic 6. 0 over its successor, Visual Basic . NET.[3][9] In 2. 01. Visual Basic 6. 0.[1. In 2. 01. 6, Visual Basic 6. The 1. 9th Annual D. I. C. E. Awards.[1. A dialect of Visual Basic, Visual Basic for Applications (VBA), is used as a macro or scripting language within several Microsoft applications, including Microsoft Office.[1. Language features[edit]Like the BASIC programming language, Visual Basic was designed to accommodate a steep learning curve. Programmers can create both simple and complex GUI applications. Programming in VB is a combination of visually arranging components or controls on a form, specifying attributes and actions for those components, and writing additional lines of code for more functionality. Since VB defines default attributes and actions for the components, a programmer can develop a simple program without writing much code. Programs built with earlier versions suffered performance problems, but faster computers and native code compilation has made this less of an issue.[citation needed] Though VB programs can be compiled into native code executables from version 5 on, they still require the presence of around 1 MB of runtime libraries. Core runtime libraries are included by default in Windows 2. Earlier versions of Windows (9. NT), require that the runtime libraries be distributed with the executable. An empty form in Visual Basic 6. Forms are created using drag- and- drop techniques. A tool is used to place controls (e. Controls have attributes and event handlers associated with them. Default values are provided when the control is created, but may be changed by the programmer. Many attribute values can be modified during run time based on user actions or changes in the environment, providing a dynamic application. For example, code can be inserted into the form resize event handler to reposition a control so that it remains centered on the form, expands to fill up the form, etc. By inserting code into the event handler for a keypress in a text box, the program can automatically translate the case of the text being entered, or even prevent certain characters from being inserted. Visual Basic can create executables (EXE files), Active. X controls, or DLL files, but is primarily used to develop Windows applications and to interface database systems. Dialog boxes with less functionality can be used to provide pop- up capabilities. Controls provide the basic functionality of the application, while programmers can insert additional logic within the appropriate event handlers. For example, a drop- down combination box automatically displays a list. When the user selects an element, an event handler is called that executes code that the programmer created to perform the action for that list item. Alternatively, a Visual Basic component can have no user interface, and instead provide Active. X objects to other programs via Component Object Model (COM). This allows for server- side processing or an add- in module. The runtime recovers unused memory using reference counting, which depends on variables passing out of scope or being set to Nothing, avoiding the problem of memory leaks common to other languages. There is a large library of utility objects, and the language provides basic support for object- oriented programming. Unlike many other programming languages, Visual Basic is generally not case- sensitive—though it transforms keywords into a standard case configuration and forces the case of variable names to conform to the case of the entry in the symbol table. String comparisons are case sensitive by default. The Visual Basic compiler is shared with other Visual Studio languages (C, C++). Nevertheless, by default the restrictions in the IDE do not allow creation of some targets (Windows model DLLs) and threading models, but over the years, developers have bypassed these restrictions. Characteristics[edit]. The code windows in Visual Basic, showing a Function using the If, Then, Else and Dim statements. Visual Basic builds upon the characteristics of BASIC. There are no line numbers as in earlier BASIC, code is grouped into subroutines or methods: Sub.. End Sub . Code Statements have no terminating character other than a line ending (carriage return/line feed). Versions since at least VB 3. Code comments are done with a single apostrophe (') character. This is a comment. Looping statement blocks begin and end with keywords: Do.. Loop, While.. End While, For.. Next .[2. 0]Multiple variable assignment is not possible. A = B = C does not imply that the values of A, B and C are equal. The boolean result of "Is B = C?" is stored in A. The result stored in A would therefore be either false or true. Boolean constant True has numeric value −1.[2. This is because the Boolean data type is stored as a 1. In this construct −1 evaluates to 1. Boolean value True), and 0 as 1. Boolean value False). This is apparent when performing a (bitwise) Not operation on a 1. True = Not False. This inherent functionality becomes especially useful when performing logical operations on the individual bits of an integer such as And, Or, Xor and Not.[2. This definition of True is also consistent with BASIC since the early 1. Microsoft BASIC implementation and is also related to the characteristics of CPU instructions at the time. Logical and bitwise operators are unified. This is unlike some C- derived languages (such as Perl), which have separate logical and bitwise operators. This again is a traditional feature of BASIC. Variable array base. Arrays are declared by specifying the upper and lower bounds in a way similar to Pascal and Fortran. It is also possible to use the Option Base statement to set the default lower bound. Use of the Option Base statement can lead to confusion when reading Visual Basic code and is best avoided by always explicitly specifying the lower bound of the array. This lower bound is not limited to 0 or 1, because it can also be set by declaration. In this way, both the lower and upper bounds are programmable. In more subscript- limited languages, the lower bound of the array is not variable. This uncommon trait does exist in Visual Basic . NET but not in VBScript. OPTION BASE was introduced by ANSI, with the standard for ANSI Minimal BASIC in the late 1. Relatively strong integration with the Windows operating system and the Component Object Model. The native types for strings and arrays are the dedicated COM types, BSTR and SAFEARRAY. Banker's rounding as the default behavior when converting real numbers to integers with the Round function.[2. Round(2. 5, 0) gives 2, ? Round(3. 5, 0) gives 4. Integers are automatically promoted to reals in expressions that involve the normal division operator (/) so that division of one integer by another produces the intuitively correct result. VB provides a specific integer divide operator (\) that does truncate. By default, if a variable has not been declared or if no type declaration character is specified, the variable is of type Variant. ![]() FL Studio 12 Crack is a music production environment or Digital Audio Workstation.

This tutorial shows you how to use MySQL ON DELETE CASCADE to delete data from a child table automatically when you delete data from the parent table. My. SQL DELETE - Deleting Data from a Table. Summary: in this tutorial, you will learn how to use the My. SQL DELETE statement to delete data from a single table. Introduction to My. SQL DELETE statement. To delete data from a table, you use the My. SQL DELETE statement. The following illustrates the syntax of the DELETE statement. DELETE FROM table_name. WHERE condition; In this statement: First, specify the table from which you delete data. Second, use a condition to specify which rows to delete in the WHERE clause. If the row matches the condition, it will be deleted. ![]()
Notice that the WHERE clause is optional. If you omit the WHERE clause, the DELETE statement will delete all rows in the table. Besides deleting data from a table, the DELETE statement returns the number of rows deleted. To delete data from multiple tables using a single DELETE statement, you use the DELETE JOIN statement which we will cover in the next tutorial. To delete all rows in a table without the need of knowing how many rows deleted, you should use the TRUNCATE TABLE statement to get a better performance. For a table that has a foreign key constraint, when you delete rows from the parent table, the rows in the child table will be deleted automatically by using the ON DELETE CASCADE option. My. SQL DELETE examples. We will use the employees table in the sample database for the demonstration. Note that once you delete data, it is gone. Therefore, you should backup your database before performing the DELETE statements in the next section. Suppose you want to delete employees whose office. Number is 4, you use the DELETE statement with the WHERE clause as the following query. DELETE FROM employees. Code = 4; To delete all rows from the employees table, you use the DELETE statement without the WHERE clause as follows: All rows in the employees table deleted. My. SQL DELETE and LIMIT clause. If you want to limit the number of rows to be deleted, you use the LIMIT clause as follows. DELETE FROM table. LIMIT row_count; Note that the order of rows in a table is unspecified, therefore, when you use the LIMIT clause, you should always use the ORDER BY clause. DELETE FROM table_name. ORDER BY c. 1, c. LIMIT row_count; Consider the following customers table in the sample database: For example, the following statement sorts customers by customer’s names alphabetically and deletes the first 1. DELETE FROM customers. ORDER BY customer. Name. LIMIT 1. 0; Similarly, the following DELETE statement selects customers in France, sorts them by credit limit in ascending order, and deletes the first 5 customers. DELETE FROM customers. WHERE country = 'France'. ORDER BY credit. Limit. LIMIT 5; In this tutorial, you have learned how to use the My. SQL DELETE statement to delete data from a table. Lorenzo Alberton - Articles - Extracting META information from Postgre. SQL (INFORMATION_SCHEMA)Following my tutorial on how to extract meta informations from Firebird SQL, I'm now going to show how to retrieve the same informations from Postgre. SQL, using the INFORMATION_SCHEMA (available since Postgre. SQL 7. 4) and with system catalogs (pg_class, pg_user, pg_view, etc). NB: as you probably know, you can list tables/indices/sequences/views from the command line with the \d{t|i|s|v} command, but here I want to show how to extract these informations using standard SQL queries. Test data. We need a few sample tables, indices and views to test the following queries, so let's create them. We also create a sample TRIGGER and a function.- - sample data to test Postgre. SQL INFORMATION_SCHEMA. CREATE TABLE TEST (. TEST_NAME CHAR(3. NOT NULL. TEST_ID INTEGER DEFAULT '0' NOT NULL. TEST_DATE TIMESTAMP NOT NULL.

If you want some more info about the field definitions, you can retrieve a larger subset of the fields available in the schema: SELECT a. AS ordinal_position. AS column_name. t.

If you want to know which table columns are referenced by an index, you can do it in two steps: first you get the table name and field(s) position with this query: SELECT relname, indkey.

AND indisunique != 't'. AND indisprimary != 't'. Then, using your favorite language, you explode the indkey (the key separator is a space), and for each key you run this query: SELECT t. FROM pg_index c. LEFT JOIN pg_class t. ON c. indrelid = t. LEFT JOIN pg_attribute a. ON a. attrelid = t. AND a. attnum = ANY(indkey). WHERE t. relname = 'test. AND a. attnum = 6; - - this is the index key. List CONSTRAINTs. Here's the query that will return the names of the CONSTRAINTs defined in the TEST2 table: SELECT relname. FROM pg_class.

Oracle Technology Network for Java Developers | Oracle Technology Network. RIP, Microsoft Paint. MS Paint, the first app you used for editing images, will probably be killed off in future updates of Windows 1. Paint 3. D. Microsoft lists the 3. Windows 1. 0’s next autumn update, a little X marking the end of an era. The app is certainly a relic, from a time when the casual computer user couldn’t crack open Photoshop or Skitch or Pixelmator or thousands of web apps. MS Paint can’t save image components as layers or vectors; it’s for making flat static images only. It doesn’t smooth lines or guess at your best intentions. Use Search Console to monitor Google Search results data for your properties. Set up the Toolkit This section desribes how to install or upgrade the AWS Toolkit for Eclipse. Prerequisites.

It does what you tell it and nothing more, faithfully representing the herky- jerky motion of drawing freehand with a computer mouse. It’s from a time before touch, a time before trackpads. As more sophisticated options appeared, Paint’s janky aesthetic became a conscious choice. Paint” became the metonym for that aesthetic, even if an image was actually created in another app. ![]() TV Tropes lists major limitations that came to define a certain look: the wobbly freehand lines, awkward color handling, and inappropriate export settings that give Paint its distinctive look. In 2. 01. 4, Gawker’s Sam Biddle noted Paint’s influence on conspiracy theory images, calling the form “Chart Brut.” In amateur detectives’ attempts at identifying the Boston Marathon bombers, the simplicity and jaggedness of Paint evokes the “crazy wall” aesthetic of red string and scribbled notes, apparently without irony. The same year, internet historian Patrick Davison explored Paint’s influence on the last decade of meme culture, particularly Rage Comics. The outsider- art aesthetic feels appropriate to the relatable everyday content, and makes the art form unthreatening. Of course, Paint offered a few features to smooth things out, like the circle and line tools and the “fill” tool, all used in the stoner comics of the early 1. Crucially, those circles still had jagged curves. The bright colors of stoner comics are flat, as MS Paint didn’t support gradients (without an elaborate hack). Contrast those pixellated lines with the slick, stylish face from this art tutorial: This slickness is built into Paint’s successor, Paint 3. D. From the moment you start sketching, Paint 3. D smooths out your art. It also supports automatic selection tools and content- aware fill to rival Photoshop’s.)By automatically improving art, Paint 3. D hides the process behind the image. Paint’s sloppiness is probably why rage comics got so popular. Looking at a rage comic, you can tell exactly how it was drawn, and how you might draw one yourself. By delivering exactly what the artist draws, MS Paint forms an image that the viewer can mentally reverse- engineer and imitate. Unless you go absolutely nuts with it. Reddit user Toweringhorizon painstakingly assembled the drawing “To a Little Radio” using MS Paint tools like the oil brush, stretching the medium while maintaining a pixelated look. It’s one of the top submissions to MS Paint subreddit, a beautiful collaborative art gallery. Scrolling through this art feels like flipping through the sketchbook of the most artistic kid in high school. There’s an accepted roughness, a desired minimalism. For example, the exquisite raindrops in the work above are reflected in a flat, featureless tabletop. Like a transistor radio, Paint might be showing its age, but this tenacious little gadget should not be underestimated.“To a Little Radio” doesn’t even come close to testing Paint’s limits. As we say goodbye to the app that shaped an era, let us watch this bizarrely soundtracked time lapse of drawing Santa Claus in MS Paint on Windows 7 over the course of 5. We can only believe this is real because faking it would be even harder. |
