Enter Sourcegraph. The 7-year-old San Francisco-based startup has built a platform to make all of a company's code searchable from the very first line written, allowing software engineers to find, analyze, and fix code efficiently. Onenote.
Its tools have only gotten more critical during the coronavirus pandemic, and it's making moves accordingly. Sourcegraph raised $23 million in March, in a Series B round led by Craft Ventures, but just added $5 million more to its coffers, led by Felicis Ventures. Sourcegraph plans to use its Series B to double its headcount and is already making progress: It's grown to 50 employees from 40 in March as it aims to hit 80 by the end of the year. It's raised $46 million in total and although Sourcegraph declined to share its valuation, PitchBook estimated it at $103 million after its initial Series B in March.
In the past five months, Sourcegraph also hooked Tinder and Amazon as new customers, adding them to a roster of corporate clients including Uber, Indeed, Airbnb, and Yelp. Sourcegraph charges companies a flat monthly fee based on their numbers of employees, but has custom pricing for big customers like Amazon; thousands of individuals also use Sourcegraph's free, open-source tools.
Many tech companies, including Facebook and Google, use in-house universal code search tools to help developers understand large volumes of code in complex systems, but Sourcegraph aims to give the same capabilities to companies that don't have the desire or resources to build their own internal products.
Developers can use Souregraph to change chunks of code that they're assigned to fix or add to, sift through repositories, and analyze and learn how their company codes, something that could otherwise take new employees months to nail down. The product also works alongside common developer tools, like analytics platforms and code editors.
As the coronavirus crisis has forced companies into temporary remote work — and spurred many, including Twitter, Spotify and Facebook, to embrace permanent remote work — working collaboratively across multiple code repositories can be difficult.
'How do you get by without code search? You go and tap people on the shoulder a lot,' Sourcegraph cofounder and CEO Quinn Slack said. 'But especially now with everything being remote, working from home, you can't tap people on the shoulder anymore. So code search becomes even more important.'
Slack and cofounder and CTO Beyang Liu came up with the idea while both working at Palantir Technologies as software engineers. Beyang had previously interned at Google, which was infamous among software engineers and students for its massive, comprehensive code search that was easily editable and shareable. Slack and Liu wanted to make a code search tool for any developer to use.
Code search let's developers 'stand on the shoulders of giants, learn from the best, and avoid duplicating code,' Slack said. Plus, the last decade of software development has made code search a crucial tool, according to Slack.
'There's way more developers, way more code, way more complexity. And of course, for consumers like us, it's a good thing because we get these apps that are personalized and use machine learning,' Slack said. 'But from the point of view of the software developer, things have gotten so much harder over the last 10 years.'
The company was remote-friendly from day one
When Sourcegraph was founded in 2013, the first two employees that Slack and Liu hired worked remotely. By January 2020, more than two-thirds of its employees were scattered across 11 states, Europe, Africa, the Middle East, South America, and a boat, instead of working at its Bay Area headquarters.
That's when the company decided not to renew its office space and went fully remote.
'Even if the company and the leadership says, 'Oh, it's your choice to come into the office,' it is so easy for everyone else to think, 'Is it really optional, if I want a promotion?' Slack said. 'It creates all of this stress in people.'
Slack said he travelled often while working as a developer with Palantir and Bank of America, as did many of his colleagues. Working from home was normalized in his teams.

In computer networking, tcpcrypt is a transport layer communication encryption protocol.[1][2] Unlike prior protocols like TLS (SSL), tcpcrypt is implemented as a TCP extension. It was designed by a team of six security and networking experts: Andrea Bittau, Mike Hamburg, Mark Handley, David Mazières, Dan Boneh and Quinn Slack.[3] Tcpcrypt has been published as an Internet Draft.[4] Experimental user-space implementations are available for Linux, Mac OS X, FreeBSD and Windows. There is also a Linux kernel implementation.
The TCPINC (TCP Increased Security) working group was formed in June 2014 by IETF to work on standardizing security extensions in the TCP protocol.[5] In May 2019 the working group released RFC8547 and RFC8548 as an experimental standard for Tcpcrypt.
Description[]
Tcpcrypt provides opportunistic encryption — if either side does not support this extension, then the protocol falls back to regular unencrypted TCP. Tcpcrypt also provides encryption to any application using TCP, even ones that do not know about encryption. This enables incremental and seamless deployment.[6]
Unlike TLS, tcpcrypt itself does not do any authentication, but passes a unique 'session ID' down to the application; the application can then use this token for further authentication. This means that any authentication scheme can be used, including passwords or certificates. It also does a larger part of the public-key connection initiation on the client side, to reduce load on servers and mitigate DoS attacks.[6]
History[]
The first draft of the protocol specification was published in July 2010, with reference implementations following in August. However, after initial meetings in IETF, proponents of the protocol failed to gain traction for standardization and the project went dormant in 2011.[7]
In 2013 and 2014, following Edward Snowden's Global surveillance disclosures about the NSA and agencies of other governments, IETF took a strong stance for protecting Internet users against surveillance.[8][9] This aligns with tcpcrypt's goals of ubiquitous transparent encryption, which revived interest in standardization of the protocol. An official IETF mailing list was created for tcpcrypt in March 2014,[10] followed by the formation of the TCPINC (TCP Increased Security) working group in June[5] and a new version of the draft specification.
Performance[]
Quinn Slack Shirtless
Tcpcrypt enforces TCP timestamps and adds its own TCP options to each data packet, amounting to 36 bytes per packet compared to plain TCP. With a mean observed packet size for TCP packets of 471 bytes,[11] this can lead to an overhead of 8% of useful bandwidth. This 36 bytes overhead may not be an issue for internet connections faster than 64kbs, but can be an issue for dial up internet users.
Compared to TLS/SSL, tcpcrypt is designed to have a lower performance impact. In part this is because tcpcrypt does not have built-in authentication, which can be implemented by the application itself. Cryptography primitives are used in such a way to reduce load on the server side, because a single server usually has to provide services for far more clients than reverse.[6]

Implementations[]
The current user space implementations are considered experimental and are reportedly unstable on some systems. It also does not support IPv6 yet, which is currently only supported by the Linux kernel version. It is expected that once tcpcrypt becomes a standard, operating systems will come with tcpcrypt support built-in, making the user space solution unnecessary.[citation needed]
