    <p>I am a software developer. I am particularly fond of the areas: <ul> <li> artificial intelligence, computer vision &amp; machine learning</li><li>high end graphics &amp; image processing</li><li>games</li></ul></p> <p>As stackoverflow changed their icon in celebration for several days when the US Supreme court unlawfully legislated to make gay marriage legal, I will in turn address the matter in my stackoverflow profile. That is the only way I can, in good conscience, continue to participate in stackoverflow.</p> <p>I stand by the bible's teachings on the matter of homosexuality. I am a member of the Church of Jesus Christ of Latter-Day Saints, also known as a Mormon. That means I consider homosexuality and related immorality to be a perversion. By contrast I consider marriage to be sacred. The court has no more right to redefine the family than government can change the fact that men are born with God given inalienable rights. <br></p> <p>I am also a mathematician.<br> I quite like interesting games and enjoy playing them with those of my many wonderful children who are old enough. We will often edit what we might find to be sleazy in a game without altering the game play, which quite widens the range of games we can play while staying within what we consider to be gospel standards.</p>

    1. COI thought StopWatch only used the usual times windows offers, e.g. with a resolution of about 10-15ms (which I would guess is really updated with each thread switch). Am I wrong about StopWatch being only a fairly course timer?

    2. COInteresting. Where did you find that out? I didn't know that. It isn't sending that 730,000 bytes. If it sent even a fraction of that there would be no problem. When it deadlocks, it just got an ACK, sent a single push packet, and refuses to send more until it gets another ACK. If it would send just one more packet of 1460 bytes the deadlock wouldn't be there (since MS TCP would send a no-data ACK when it got the second packet). As we have played with it the size of the outgoing message (meaning how much data is posted in each socket.send command) appears important in the MS heuristics.

    3. COActually we used wireshark to get most of the information above. We have have a very large receive window (window scaling is automatically invoked by windows since our receive buffer is large). We need speeds on the order of at least 450 Mbs over 1000Mbs ethernet. Should be doable. The receiving side primarily moves the data around in memory right now. The pauses exactly correspond to the time socket.recv takes to return, and not to the return time of any other function. It only happens in just the right circumstance.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
