70 Things Every Computer Geek Should Know. The term ‘geek’, once used to label a circus freak, has morphed in meaning over the years.

Fitbit One Review: Slightly Flawed, But Still A Great Way To Quantify Yourself The original Fitbit first saw the light of day over four years ago, and boy how things have changed since then. Now it seems like everyone from old incumbents to ambitious upstarts have offered their own takes on the activity-tracking formula, so how does Fitbit’s newest offering stack up to the competition? The Fitbit One is… A small, two-tone doodad that will set you back $99 and track your movement throughout the day. Before I ramble on for too much longer, know this: the Fitbit works like a treat. The only thing that didn’t impress as much as I expected it to was the One’s oft-touted sleep tracking feature — I could never get the Fitbit to proffer an amount of time slept that matched up with how much sleep I thought I got. What else does it do? The Fitbit experience is only as solid as its other half — the part that takes all of that activity information and turns it into a comprehensive suite of personal analytics. And then there are the touches that you’ll hardly ever notice.
Excel COUNTIFS and COUNTIF with multiple criteria – examples of usage The tutorial explains how to use COUNTIFS and COUNTIF formulas with multiple criteria in Excel. You will find a number of examples for different data types - numbers, dates, text, wildcard characters, non-blank cells and more. Of all Excel functions, COUNTIFS and COUNTIF are probably most often mixed up because they look very much alike and both are purposed for counting cells based on the specified criteria. The difference is that the COUNTIF function is intended for counting cells based on a single condition in one range, while COUNTIFS allows using several criteria and ranges.

COUNTIFS syntax The syntax of the COUNTIFS function is as follows: COUNTIFS(criteria_range1, criteria1, [criteria_range2, criteria2]…) Example 1. Tip.
Insertar un gráfico | Diagramas en LibreOffice Calc A la hora de crear un diagrama en Calc podemos seguir diferentes guiones, y en todos los casos obtendremos el resultado deseado. El asistente de diagramas permite en cuatro pasos insertar un nuevo diagrama. Nosotros agregaremos un paso previo, al que denominaremos el paso 0: Paso 0: Seleccionar los datosPaso 1: Tipo de diagramaPaso 2: Rango de datosPaso 3: Series de datosPaso 4: Elementos de diagramas Paso 0: Seleccionar los datos Este paso consiste en seleccionar previamente los datos que quiera representar gráficamente. Como podemos ver en el ejemplo, seleccionaremos siempre las cabeceras tanto de filas como de columnas. No es recomendable seleccionar los totales, pues en tal caso, los datos parciales siempre parecerán mucho menores comparados con éstos, y será mucho más difícil ver las diferencias entre cada una de las series de datos ¿Y qué son las series de datos? Ahora activaremos el asistente para diagramas. Desde el menú Insertar > Diagrama Paso 1: Tipo de diagrama En nuestro ejemplo:
The Two Online Security Steps You Should Stop Putting Off - NYTimes.com My favorite password manager is LastPass — which our friends at The Wirecutter, a New York Times company, also recommend — because it works with every browser, it works with most mobile phones, and its interface is relatively simple. Most password managers generally work the same way: You set up one master password for the manager itself, and from then on you use its browser plugin (or mobile app) to create and manage every other password you need. Every account gets a unique password, meaning that if one account is compromised (like in a mass data breach), your other accounts will remain safe. If you’re still not convinced about the paramount importance of strong password management, here’s some further reading. Two-factor authentication goes a step further by requiring a username, password and access to your mobile phone to log in to an account. And, while we’re on the subject, here are more ways to protect your identity online. Have a great week! —Tim Best of Smarter Living
