Facebook open-sources its deep-learning AI tools
Facebook is sharing some of its technology. The company’s artificial intelligence research team today announced that it is open sourcing its deep-learning AI tools.
The software will be available on the Torch library, which serves as an open-source environment for machine learning development. Torch is widely used for research in academia, as well as by companies like Google, Twitter and Intel.
Facebook claims its deep-learning modules are significantly quicker than the default ones available through Torch, and allow the company to work on larger neural networks in less time.
Notable improvements include a 23.5x speed-up over publicly available convolutional layer codes, and the ability to parallelize neural networks training over GPU cards.
The company hopes sharing its tools will help optimize progress across the entire deep-learning research landscape.

为小公司而生的律师匹配服务 Lexoo 获 40 万美元融资
在我自己的创业冒险旅程中，我得出了这样一条结论，无论你是成功还是失败，肯定能赚钱的只有两种人，云服务提供商和律师。关于前者，价格和竞争形势都相当的透明。然而律师费就远非如此了。这正是英国创业公司 Lexoo 正在着手解决的问题。
为了帮助实现这一愿景，这家提供了自称为“律师匹配”服务的伦敦公司刚刚完成了 40 万美元的种子轮投资，投资方为 Forward Partners——一家 由尼克·布里斯伯恩（Nic Brisbourne）领导 的风投公司及创业公司“工厂”——以及乔纳森·麦凯（Jonathan McKay，JustGiving 董事长）。
“对于小公司来说，找到一名优秀律师并在此过程中不挨宰是件难事，”Lexoo 联合创始人兼首席执行官丹尼尔·范·宾斯伯根（Daniel van Binsbergen）解释道，此前他曾是一位专注于金融与并购领域的律师。“名牌律师事务所通常都很棒，但管理费用繁杂，因此每小时收费很高。对于小公司而言，很难知道哪一位律师真的能干，是否擅长这一领域。最后，如果你采用一名推荐律师的话，很难判断你给出的价格是否合理。”
为了解决这一难题——可以将此视作网络将市场变得更加高效透明的经典案例——公司可以根据工作类型需求，通过 Lexoo 平台获得一批精选律师队伍的多方报价。在 Lexoo 平台发布工作后，你会从多个胜任该工作的律师收到富有竞争力的报价，通常在 24 小时内。
“我们确保只有真正擅长于特定法律领域的律师才能为某件工作报价，每一位律师加入平台之前，我们都会对他进行面试，”范·宾斯伯根说道，“客户可以将报价和律师履历进行比较，做出更加明智的决定。我们的卖点在于，帮你找到曾在大型律师事务所摸爬滚打的资深律师，只不过他们现在因为生活方式的原因选择在家工作或者在小公司工作。这一点使得他们的常规报价只有之前每小时费用的一半左右。”
为此 Lexoo 不收取客户费用，不过律师需要将任何通过这一平台拿到的工作报酬的 10%作为佣金付给这家创业公司。
Lexoo Scores $400K For Its Lawyer-Matching Service For Small Businesses
During my own startup adventures, I came to the conclusion that, succeed or fail, the only people guaranteed to make money are cloud providers and lawyers. With regards to the former, pricing and competition is fairly transparent. But legal fees, not so much. That’s the problem UK startup Lexoo has set out to solve.
To help with that mission, the London-based company, which offers what it calls a ‘lawyer-matching’ service, has just scored a $400k seed round from Forward Partners — the venture firm and startup ‘foundry’ headed up by Nic Brisbourne — and Jonathan McKay (Chairman of JustGiving).
“It’s difficult for small businesses to find a good lawyer and not get overcharged in the process,” explains Lexoo co-founder and CEO Daniel van Binsbergen, who previously worked as a lawyer focussing on finance and M&A. “Brand name law firms are usually great but have a lot of overheads and therefore high hourly rates. With smaller firms it is hard to know which lawyers are actually good and specialised. Finally, if you go with a recommended lawyer it is hard to judge whether the price you are quoted makes sense or not.”
To tackle this — in what can be considered a classic example of how markets can be made more efficient and transparent by moving them online — Lexoo enables businesses to get multiple quotes from a curated line-up of lawyers, based on the type of work required. After posting a job, you receive multiple and competitive quotes from the qualified lawyers on the platform, usually within 24 hours.
“We make sure that only lawyers who are actually specialised in a certain area of law are invited to quote for a job and we screen and interview every single lawyer before they can join the platform,” says van Binsbergen. “Customers can then compare the quotes and lawyer profiles and make a much more educated decision. Our sweet spot is finding lawyers who trained at the largest firms but for lifestyle reasons are working at home, virtually or in a small office. This enables them to usually charge only 50 per cent of their previous hourly rates.”
To that end, Lexoo is free for clients, but lawyers pay the startup a 10 per cent commission on any work they obtain through the platform.

企业级匿名分享应用 Memo：为员工之间坦诚交流架起桥梁
在过去的一年，我们看到大量匿名应用在手机上纷纷出现，允许用户与附近的人或是社交圈子里的人分享信息。但到目前为止，其中大多数匿名应用都专注于消费者市场。
一款名为 Memo 的新应用希望可以从企业级市场分得一杯羹，让公司员工可以与同事匿名、私下分享信息。
Memo 由纽约市一家名为 Collectively 的公司开发，该公司寻求以全新的方式“让工作变得更具人性化”。Memo 背后的创意与其他众多匿名分享应用的创意一样，即只要不让用户在帖子中暴露自己的身份，他们会更为坦诚地分享在实名状况下不敢公开的事情。
为了保证用户确实在某家公司工作，Memo 要求他们在注册时必须提供公司的电子邮箱地址，或是通过 LinkedIn 来验证他们的雇员身份。在身份验证步骤完成以后，Memo 会向用户提供唯一识别代码，但除此之外，不会保存其他任何身份信息。
一旦上述步骤全部完成，用户可以在公司内网与其他员工在私下交流。他们也可以与其他用户公开分享信息，但必须由 任职单位“ 验明正身”。
Collectively 首席执行官莱恩·延森（Ryan Janssen）表示，Memo 的目标是让公司的员工之间进行更坦诚的交流。他认为，不少大公司的高管经常不与普通员工接触。
延森在接受我电话采访时说：“一些企业之所以陷入困境，是因为他们不倾听员工的声音。”但他也暗示，员工们也不敢分享他们对发生在公司内一些事情的看法。
延森说：“管理层具有双重角色…一方面，他们被认为应该为公司内的交流提供便利，但另一方面，他们还决定着员工们的命运。这两种角色恰恰存在着矛盾。”
为了测试这种假设，Collectively 去年秋天首先面向惠普、IBM、亚马逊和花旗集团等大公司的员工推出 Memo。该应用被数千名员工下载到手机，当作私密移动留言板在这些公司中使用，如今 Memo 已经完全开放，所有人都能下载。
Memo 没有权限访问在这些私密留言板上进行的任何对话。Collectively 希望采用的商业模式是，推出一系列管理层可以使用的工具，包括分析工具、情绪分析工具，以及能对员工之间分享的消息作出回复的解决方案。
即便如此，有些公司仍然对员工在 Memo 上面匿名分享的事情感到不满。延森说，已有两家员工使用 Memo 的公司向 Collectively 发来“停止通知函”（cease-and-desist order），另外该公司还收到了其他多家企业发来的“措辞强烈”的电子邮件。
此外，延森告诉我，还有三家公司的员工“收到了一份备忘录，警告他们不要使用 Memo，这种做法真是具有讽刺性”。延森表示，他并未看到这些备忘录，只是通过 Memo 的信息反馈栏听说的。
有些公司还试图通过拦截身份验证电子邮件或是发自员工收件箱的邀请函，不让本公司员工使用 Memo。不过，延森认为企业的这种反应其实是件好事。在收到这种电子邮件以后，延森可以与一些公司坐下来谈一谈，找到更好的合作办法，同时研究 Collectively 应该推出哪些工具，帮助这些企业对员工在 Memo 中反映的事情作出回应。
虽然 Memo 迈出了不错的第一步，但很显然，在企业接受了有关员工在公司内部匿名分享信息的创意之前，Memo 还有很长的路要走。
Memo Brings Anonymous Group Sharing To The Enterprise
Over the last year, we’ve seen a bunch of anonymous (or anonymish) apps crop up on mobile phones, allowing users to share messages with people nearby or those in their social circles. To date, though, most of those apps have been focused on the consumer market.
A new app called Memo hopes to capture some of the enterprise market, enabling employees to share anonymously and privately with their coworkers.
Memo was created by a New York-based group called Collectively, which is looking for new ways to “help make work more human.” The theory behind Memo, like that behind many other anonymous sharing apps, is that by removing a user’s identity from a post they would be much more honest with the things they chose to post.
In order to ensure users work at a certain organization, Memo requires them to sign up with a company email address or verify their employment by connecting through LinkedIn. After that verification takes place, Memo provides users with a unique user ID but doesn’t save any other identifiable information.
Once that’s all done, users can share privately with other employees within their company’s network. They can also share publicly to any other users, but they are identified only by the company they work for.
For CEO Ryan Janssen, Memo’s goal is to open up more honest communication within an organization. All too often, he believes, senior management in many big companies is out of touch with the average worker.
“Companies are suffering because they aren’t listening to their employees,” Janssen told me in a phone interview. But he suggests employees are afraid to share what they really think about what’s happening in their organizations.
“Managers have this bifurcated role… On the one hand they are supposed to facilitate communication throughout the company, but they also determine employees’ futures. Those roles are in opposition to each other,” Janssen said.
To test out this hypothesis, the company made Memo available to employees within organizations like HP, IBM, Amazon, and Citigroup last fall. The app was downloaded by thousands of employees and used as a private mobile message board in those companies, and now it’s being opened up so that anyone can download it.
Memo doesn’t have access to any of the conversations that happen within those private boards. The business model it hopes to employ is to roll out tools that management can use that could include analytics tools, sentiment analysis, and ways to respond to messages that employees share.
That said, some companies aren’t happy about the things their employees have been sharing anonymously on Memo. Janssen says he’s received two cease-and-desist orders from companies with employees on Memo and some “strongly worded” emails from a few other organizations.
In addition, he told me employees at three other companies “received a memo not to use Memo, which is a little ironic.” Janssen says he hasn’t actually seen those memos, just heard about them through the app’s feedback form.
While some companies have tried to shut down use of Memo by blocking verification emails or email invites from hitting employee inboxes, Janssen thinks the backlash is actually a good thing. As a result of the emails he’s received, Janssen has been able to set up meetings with a few companies to figure out how he can better work with them and which tools he could implement to help them respond to employee feedback in the app.
It’s a good first step, but there’s obviously a long road ahead before companies get comfortable with the idea of anonymous sharing in the enterprise.
