Im Slack CTO Cal Henderson, and This Is How I Work. Cal Henderson is the co founder and CTO of Slack, the leading workplace messaging platform, which Hendersons team invented while trying to build an online game called Glitch. That wasnt the first time Henderson and his Slack co founder Stewart Butterfield set out to build a game and ended up with a startup. In the early 2. 00. Henderson joined Butterfields team to build Game Neverending, which spawned the photo sharing site Flickr. Hes been programming and blogging at iamcal. We talked to Henderson about how he works, how he Slacks, and how it feels to pivot into massive successtwice. A typewriter is a mechanical or electromechanical machine for writing characters similar to those produced by printers movable type. A typewriter operates by means. In the original design style, now known as a mechanical or manual typewriter, each key was attached to a typebar that had the corresponding letter molded into.

I got into computers at a pretty young age it started when my older cousin got a Texas Instruments TI 9. I was around six. Like most computers at the time, it came with a BASIC interpreter, and I was fascinated. Within a few years I had decided that programming is what I wanted to do when I grew up. Ive been pretty obsessed ever since.

What were these pivots like What was different the second time around, Slack vs. Flickr The pivots were hardno one sets out to fail. You dont know, when youre going through shutting down a failed company, that there will be a good outcome on the other side. Whats been different this time around is the growth and maturity of the web as a platformthere are 1. When we built Flickr, the idea of putting your photos online was pretty new. Now the idea of putting them anywhere else is weird. The other big shift is the development of infrastructure and the cloud. The bar to getting started has gotten lower and lower, allowing you to spend less time racking servers and more time working on the thing youre trying to build.

What everyday thing are you better at than everyone elseWhats your secret Thats a bit full on. Clay Modeling Ideas there. Ive been told I have a tremendous capacity for focused work and high output, but whats allowed me to grow into the CTO role at an org the size of Slack has been my 1. I find in the human aspects of the work. Theres a very prevalent stereotype that engineers are socially unsophisticated, but thats just not the case. Interpersonal communication is an absolute requirement for management and leadership in all functions of a company, and no less so in engineering. Its a team activity. What apps, software, or tools cant you live withoutWork Slack. News BBC, Twitter. Family Whatsapp, Snapchat. Entertainment Audible, Reddit. Whats your biggest struggle in the workplace Probably prioritizing my time. As an organization grows in size and complexity, its easy to fall into just being reactive. Theres always one more thing coming to you that wants attention and needs to be done now. But stepping back and being strategic about what you focus on is really important. What do you listen to while you work I spend most of my workday in meetings, but when Im working from home Ill plug into Spotifythis week has been a mix of Kanye and British trip hop group Sneaker Pimps. What are you currently reading, or what would you recommend I recently finished Ada Palmers Terra Ignota series, which I strongly recommend. A view of humanity post scarcity and what it takes to hold a society together. Whats the best advice you ever received Im not sure where this advice came from, but the idea of finding a set of people you like to work with, rather than the perfect project. We didnt set out to make Flickr, or start a company to make Slack, but finding a group of people that you trust and love to work with means that you enjoy what youre doing, even when you pivot into something completely different. And to drink lots of water and get regular exercise. Whats the greatest idea youve had that you dont want to do yourself I still think that what we were trying to do with Glitch a multiplayer online social game space around would building and collaboration is a great idea. We didnt manage to make it into a successful business and I dont think Ill try doing it again, but the core of the idea was great. If someone manages to make what we were aiming to, Id play the shit out of it. Whats your own Slack etiquette, and how much does it line up with the rest of your teamFor example, how much do you use Slack during off hours Have you ever made a big faux pas like sending a sensitive message to the wrong channel I think I make that mistake more often with email than with Slack, probably because I use it less frequently. While I read Slack at all hours, I try to avoid DMing people late at night. The pressure for people to respond quickly can guilt people into thinking they need to be always on. Queuing up a bunch of messages to send first thing in the morning lets people know that my questions can wait. Youve pulled off some great stunts, like the who looks like a manager game at Yahoo. Hendersons game asked fellow Yahoo employees to guess which of two people was higher up at the company, based only on their photos. What role have side projects played in your career I had a lot of fun with the early internal Hack Days at Yahoo, showing that you could build interesting projects that werent just a user facing product feature. Playing Game Never Ending the game that preceded Flickr was something I did for fun in my spare time in my early 2. Stewart to come work at Flickr. Fill in the blank Id love to see answer these same questions. Introduction to Computers. The Big Picture. A computer system has three main components hardware, software, and. The equipment associated with a computer system is called hardware. Software is a set of instructions that tells the hardware what to do. People, however, are the most important component of a computer system people use. In fact, this course will show you that the computer can be a tool. Software is actually a computer program. To be more specific, a program. A computer programmer. Most of us do not write programs, we use programs. This means we are. Hardware Meeting the Machine. What is a computer A six year old called a computer radio, movies, and. A ten year old described a computer as a television. The ten year olds definition is closer but still does not. A computer is a machine that can be programmed to accept data input. The processing of. To function, a computer system requires four main aspects of data handling input. The hardware. responsible for these four areas operates as follows. Input devices accept data in a form that the computer can use they then. The processor, more formally known as the central processing unit. CPU, has the electronic circuitry that manipulates input data into the. The central processing unit executes. Output devices show people the processed data information in a. Storage usually means secondary storage. Secondary storage consists. These devices supplement the computers memory. Now let us consider the equipment related to these four aspects of data. Your Personal Computer Hardware. Let us look at the hardware in terms of a personal computer. Suppose you. want to do word processing on a personal computer, using the hardware. Figure 1. Word processing software allows you to input data. The input device, in this case, is a keyboard, which you use to type. All. computers, large and small, must have a central processing unit within the personal. The central processing unit under the direction of the. Processed data from your personal computer is. As you key in the. After you. examine the essay on the screen, make changes, and determine that it is. Your secondary storage. Now we will take a general tour of the hardware needed for input, processing, output. These same components make up all computer systems, whether small, medium. In this discussion we will. These topics will be covered in detail in later chapters. Input What Goes In. Input is the data that you put into the computer system for processing. Here are some common ways of feeding input data into the system. Typing on a keyboard. Computer keyboards operate in. The computer. responds to what you enter that is, it echoes what you type by displaying it on the. Pointing with a mouse. A mouse is a device that is moved. As the ball on its underside rotates, the. Pressing buttons on the mouse lets you invoke commands. Scanning with a flatbed scanner, wand reader or bar code reader Figure 3. Flatbed scanners act like a copying machine by using light beams to scan a. A great way to send. Bar scanners, which you have seen in retail stores, use laser beams to read. You can input data to a computer in many other interesting ways. We will examine all these in detail in a later chapter. The Processor and Memory Data Manipulation. In a computer the processor is the center of activity. The processor, as we. CPU. The central processing. It is the central processing unit that actually transforms data into information. Data is the raw material to be processed by a computer. Such. material can be letters, numbers, or facts like grades in a class, baseball batting. Processed. data becomes information, data that is organized, meaningful, and useful. In school, for. instance, an instructor could enter various student. Data that is perhaps uninteresting on its. The. raw facts data about your finances, such as a paycheck or a donation to. Computer memory, also known as primary storage, is closely associated. Memory holds the. In addition, memory holds the programs computer. Output What Comes Out. Output, the result produced by the central processing unit, is. Output is usable information that. The most. common forms of output are words, numbers, and graphics. Word output, for example. Other workers may be more. In many cases numbers can be understood more easily when output in the form of. The most common output devices are computer screens Figure 3and printers Figure 4. Screens can vary in their forms of display, producing text, numbers, symbols, art. Printers produce printed. You can produce output from a computer in other ways, including film. We will examine all output methods in detail in a later chapter. Secondary Storage. Secondary storage provides additional storage separate from memory. Secondary. storage has several advantages. For instance, it would be unwise. Also, memory holds data. Secondary storage is needed for large volumes. The two most common secondary storage mediums are magnetic disk. A magnetic disk can be a diskette or a hard disk. Hand Mac Trial here. A. diskette is usually 3 12 inches in diameter. A diskette is removable so. Hard disks, shown in. Figure 5, have more. Hard disks are often contained in disk. Figure 6 that is built into the computer so your data stays. Disk data is read by disk drives. Personal computer disk drives read. Modern. personal computers are starting to come with removable storage media, like. Zip disks. These disks are slightly larger than a diskette and can be inserted. CPU to access than a diskette. Most modern computers also come with. CD ROM drive. A CD is an. CDs are removable and. Some CD drives are. ROM, which means that your computer can read programs. CDs, but you can not save data to the CD yourself. Recently CD RW drives and disks have become widely available that allow you to create your own CDs by writing data such as music and photos to the CD. Magnetic tape, which comes on a reel or cartridge shown in Figure 7. Magnetic tape reels are mounted on tape. Magnetic tape is. CDs. We will study storage media in a later part of the course. The Complete Hardware System. The hardware devices attached to the computer are called peripheral. Peripheral equipment includes all input, output, and secondary. In the case of personal computers, some of the input, output, and storage. In many personal computers, the CPU and disk drive are all contained in the same. In larger computer systems, however, the input, processing, output, and. For example, data may be input on terminals at a. The information produced by the central processing. Meanwhile, disks with stored data may be kept in bank headquarters and duplicate data kept on disk or tape in a warehouse across. Although the equipment may vary widely, from the simplest computer. Now let us look. at the way computers have been traditionally classified. Classification of Computers. Computers come in sizes from tiny to monstrous, in both appearance and. The size of a computer that a person or an organization needs. Clearly, the National Weather. Service, keeping watch on the weather fronts of many continents, has. And the requirements of both. Supercomputers. The mightiest computers and, of course, the most expensive are known. Figure 1 6a. Supercomputers process billions of. Most people do not have a direct need for the. In fact, for many years supercomputer customers were an exclusive group agencies of the federal government. The federal government uses supercomputers for tasks that require. But now supercomputers are moving toward the mainstream, for activities.
