How Expedia.com was built on machine learning

Expedia has grown far beyond a search engine for flights -- it's now the parent company of a dozen travel brands including Trivago and Hotels.com -- but according to VP of global product David Fleischman, machine learning has always been at the heart of the company's operations.The business of delivering quality flight search results is tough, and Fleischman describes it as an "unbounded computer science problem". The reason for this is because flight itineraries and schedules are constantly changing, and Expedia's proprietary 'best fare search' (BFS) has to 'learn' and adapt all the time.The extent of the problem can be summed up by one statistic. The average Expedia.com flight search will take three seconds to deliver results. In those three seconds you will see, on average, 16,000 flight options, in order of convenience or price or time.To read this article in full or to leave a comment, please click here

End to free upgrade halts rapid Windows 10 growth

As expected, Windows 10's usage share growth sank after Microsoft ended the free upgrade it had offered customers for the past year. According to analytics vendor StatCounter, Windows 10's week-over-week gains in the first two weeks of August were 0.13 and 0.15 percentage points, respectively. The increases were the smallest of any two-week span this year, with the exception of two different times -- in April, again in July -- when Windows 10's share fell from one week to the next. If the remainder of August plays out the same as the first half, Windows 10 will post a one-month increase about a third of July's and approximately a fourth of June's.To read this article in full or to leave a comment, please click here

Microsoft acknowledges Anniversary Update causes freezing

After a lot of anecdotal reports, Microsoft acknowledged there is a problem with the Anniversary Update to Windows 10 causing PCs to freeze up. However, it says the problem is isolated to a specific PC configuration.In a Windows forum post, Microsoft claims the freezing issue is experienced only on computers with SSDs where apps are installed on a different drive than the one where Windows 10 is installed. The obvious workaround is to move all apps to the drive where Windows 10 is located, and the company actually recommends this.To read this article in full or to leave a comment, please click here

Intel is leaving PCs behind to highlight VR and IoT at IDF

For decades, PCs were at the center of Intel's business, but not anymore.Self-driving cars, virtual reality, and artificial intelligence are more attractive to Intel, which no longer views PCs as a priority. That's the message the company will try to deliver at Intel Developer Forum, starting on Tuesday.IDF attendees will see drones fly around and robots roaming the floor, and they will be able to try on cool wearables and VR and AR (augmented reality) headsets.Unlike past years, attendees won't be wowed with a lot of blazing laptops and desktops running upcoming PC processors. Instead, Intel will provide an insight into its internet-of-things and data-center strategies. To read this article in full or to leave a comment, please click here

Much ado about the ransomware scourge

The Federal Trade Commission said it will hold a public workshop about all things ransomware on Sept. 7.“With alarming frequency, ransomware hackers are sneaking into consumer and business computers, encrypting files containing photos, documents and other important data, and then demanding a ransom in exchange for the key needed to decrypt the files. Consumers, businesses, and government agencies are falling prey to these schemes, including hospitals whose servers may contain sensitive patient data. New forms of ransomware encrypt files of website operators, threatening not only their files containing stored data, but the very files needed to operate their websites. Other variants of ransomware are now targeting files on mobile devices,” the FTC wrote.To read this article in full or to leave a comment, please click here

snaproute Go BGP Code Dive (8): Moving to Open

Last week we left off with our BGP peer in connect state after looking through what this code, around line 261 of fsm.go in snaproute’s Go BGP implementation—

func (st *ConnectState) processEvent(event BGPFSMEvent, data interface{}) {
  switch event {
  ....
    case BGPEventConnRetryTimerExp:
      st.fsm.StopConnToPeer()
      st.fsm.StartConnectRetryTimer()
      st.fsm.InitiateConnToPeer()
....

What we want to do this week is pick up our BGP peering process, and figure out what the code does next. In this particular case, the next step in the process is fairly simple to find, because it’s just another case in the switch statement in (st *ConnectState) processEvent—

case BGPEventTcpCrAcked, BGPEventTcpConnConfirmed:
  st.fsm.StopConnectRetryTimer()
  st.fsm.SetPeerConn(data)
  st.fsm.sendOpenMessage()
  st.fsm.SetHoldTime(st.fsm.neighborConf.RunningConf.HoldTime,
    st.fsm.neighborConf.RunningConf.KeepaliveTime)
  st.fsm.StartHoldTimer()
  st.BaseState.fsm.ChangeState(NewOpenSentState(st.BaseState.fsm))
....

This looks like the right place—we’re looking at events that occur while in the connect state, and the result seems to be sending an open message. Before we move down this path, however, I’d like to be certain I’m chasing the right call chain, or logical thread. How can I do this? This code is called when (st *ConnectState) processEvent is called with an event Continue reading
