Dica: Ampliando o tempo de gravação do desktop no Gnome-shell

25 de julho de 2015

Para aqueles que não sabem, o Gnome-Shell dispõe de uma ferramenta nativa para a gravação da área de trabalho (desktop), porém, por padrão o tempo de gravação é limitado em apenas 30 segundos, o que não dá para gravar muita coisa.

Depois de muito pesquisar encontrei aonde está setado os 30 segundos e pude alterar para um valor superior.

Antes de saber como alterar o tempo de gravação para um valor maior, saiba como gravar a sua área de trabalho para quem utiliza o Gnome-shell. As teclas de atalho para ativar e desativar a gravação são as mesmas, ou seja, aperte uma vez a sequência de telas para ativar a gravação e aperte novamente as mesmas sequências de teclas para finalizar a gravação.

Por padrão os vídeos são salvos dentro da pasta Vídeos do seu home com extensão “.webm”.

 

Para iniciar a gravação, tecle: <Ctrl><Shift><Alt>R
Para finalizar a gravação tecle a mesma sequência de teclas: <Ctrl><Shift><Alt>R

Simples, não?!

 

Agora vamos fazer a alteração para ampliar o tempo de gravação. Lembrando que o valor inserido deve ser em segundos.

gsettings set org.gnome.settings-daemon.plugins.media-keys max-screencast-length 1800

Altere apenas o valor no final. Eu deixo o meu em 30 min ou 1800 segundos. Nunca cheguei a usar mais do que isso, mas nada impede que coloque um valor maior por garantia.

*Dica do Elder Marco: Caso a valor seja setado para zero (0) a gravação não terá tempo limite de parada e só será interrompida quando o usuário o fizer.

O único “problema” é que o áudio do microfone não é capturado, mas nada o impede de editar o vídeo e inserir um áudio a parte. Também há a opção de usar a extensão EasyScreenCast, que grava com áudio e é bem customizada e simples de utilizar. Essa extensão usa o mesmo aplicativo de gravação do Gnome para realizar as gravações da tela.

    SEARCH Figuring out how much you’ve earned can be confusing at first, but the basic principle is the same as with any other bet. The odds indicate how much you will win for every $100 wagered. The proliferation of legal sports gambling in the U.S. has attracted millions of bettors. If you are a new player seeking to try your luck, it’s imperative to understand how sports betting odds work. This is a simple wager on the team that will win a particular game. Oddsmakers set a price for each team based on head-to-head records, the caliber of the roster and how well they are playing. You then choose which team you think will win and bet on it to cover the moneyline. For example, when examining a sportsbook, you may come across the following game listing: 4)     With the exception of the Moneyline, all markets including “Runline”, “Over Under”, and “Odd Even” require all scheduled innings to be completed for bets to stand. This excludes when the home team is winning, and then the required number of innings is one half less. This applies to all offers except those where the outcome has been decided prior to the abandonment and could not possibly be changed regardless of future events. These will be settled according to the decided outcome.

    Hockey parlays are the same as parlays in any other sport, as bettors combine at least two selections on the money line, total, puck line, or any combination of that and potentially other wagers, to try and score on a bigger payout.  These NHL betting lines are used for wagers on who will win the game. They show how much money you’ll win from a $100 bet (for the underdog) or how much money you need to wager to win $100 (for the favorite). To do this, moneyline odds are typically based on $100. When you sign-up for Unabated Essentials, you’ll get access to line history of the NHL odds, select NHL market maker odds, the compare lines feature, and many other betting calculators to help with your NHL betting. The other popular hockey bet is the total, aka the “over under” for a game. The total number of goals in an NHL game is usually set between 5 goals and 6.5 goals, but there are times when the total will be set higher or lower than that range based on matchups or betting trends. This is another wager where alternative totals can get bettors friendlier odds if, say, one result is more heavily favored than another.

    YOUR 1-STOP DIY & BUILDING MATERIAL STORE! Most antique brick prices are $1 to $2 per brick, depending on the quantity, condition, and firing method. Rare historical bricks cost $10 to $30 per brick if they are an unusual color or have a maker’s name stamp. The oldest bricks have the highest value. The prices of many building materials reached a peak during the summer of 2022 and have steadily fallen since. The reasons why building material prices have fallen are the diminishing of supply chain disruptions and weakening demand (as expected) as forecasts for economic development in many countries are lowered. Output prices of sawmills declined by 17% in November 2022 compared to their peak in April. This is due to lower demand and moderating supply chain problems. The producer prices of metal ores have come down as well but to a lesser extent.

    As the name suggests, SMO does deal with the different social networks and also helps in contributing to the ever-growing importance of the business. This is one of those aspects of optimization deals, which eventually enhances the presence of the company and increases the online reputation through different interactive communities which involve not only Twitter and Facebook, but also forums, blogs, etc. All the sources where the business is actually mentioned or linked to socially. How our commerce platform works Search engine marketing is a way for a business to market their small business online with tools like paid listings such as Google Adwords and other search engine related paid services. While the two phrases seem similar, SEO and SEM are different services, and SEM is just as important as SEO.
