Riak developers responded with messages of gratitude. A 2012 funding round from Georgetown Capital Partners and a new CEO, Greg Collins, failed to do much and by 2014, Collins was out. In late 2015, cofounder and ousted chairman of the board Earl Galleher sued Georgetown Capital Partners, claiming that the venture firm's funding terms sank the company.
That case continues to plod through the Delaware Chancery Court, delayed most recently by a change in legal representation. In April, Basho was looking to be acquired. Pivotal Solutions, the Renton, Washington-based firm handling Basho's receivership, confirmed that a deal with Bet365 is being finalized.
Why not despair about YouTube stars instead. In July, its bills unpaid, Basho was placed into receivership. A spokesperson for Bet365 wasn't immediately available for comment.

In statistics, the odds for or odds of some event reflect the likelihood that the event will take place, while odds against reflect the likelihood that it will not. In gambling, the odds are the ratio of payoff to stake, and do not necessarily reflect exactly the probabilities.
Odds are expressed in several ways (see below), and sometimes the term is used incorrectly to mean simply the probability of an event.
In both gambling and statistics, the 'odds' are a numerical expression of the likelihood of some possible event. In gambling, odds represent the ratio between the amounts staked by parties to a wager or bet.
In simplest terms, 6 to 1 odds means if you bet a dollar (the "1" in the expression), and you win you get paid six dollars (the "6" in the expression), or 6 x 1. If you bet two dollars you would be paid twelve dollars, or 6 x 2. If you bet three dollars and win, you would be paid eighteen dollars, or 6 x 3. If you bet one hundred dollars and win you would be paid six hundred dollars, or 6 x 100.
Of course if you lose any of those bets you would lose the dollar, or two dollars, or three dollars, or one hundred dollars.So next time you start to enter the same thing, type the first few letters and suggestions should appear.
This can be a security risk, so avoid on shared computers. Open Chrome, then at the top right choose 'Settings' from the drop-down menu. At the bottom of the screen click on 'Advanced'. Under 'Passwords and forms', select ' Autofill settings'. Google Chrome has a guide to its automatic form-filling feature. Click on 'Preferences', which is located in the top right hand corner of your screen near the Apple icon, then click on 'Auto-fill'. To turn AutoFill off or on, select the information you want to include in AutoFill and deselect the rest.
This doesn't always fill out forms correctly first time, so try downloading the Autofill Forms add-on, which is more sophisticated. Go to Tools, then Internet Options, click the Content tab and then AutoComplete 'Settings'. Put a tick in the box to select AutoComplete for forms. While you can set browsers to remember basic information such as names and addresses, they aren't that intelligent and often put the wrong info in fields.
Free web program Roboform is a form-filling weapon that easily outguns typing alone. It stores info such as addresses, phone numbers and postcodes and uses them to automatically fill in online forms. The details are stored on your computer. All you need to remember is the crucial master-password to access them. One consideration is Roboform blindly fills out form details in the same way as spambots, which spammers use to send scores of entries.
So some firms may mistake you for a spambot and block your entry. We've no stats on how many competitions will block you this way, but if you're worried, try AutoHotKey instead. How to set up RoboformGo to Roboform and download the program.
Once the software is installed, find the Roboform icon on your browser toolbar and click 'Identities' to create a new ID. Then simply fill in all the details you want it to remember about you, eg, name, address, postcode, date of birth.
When you see a form you want to fill in, click the Roboform icon and select your identity. This will magically fill in the blanks with your details (do double-check though). Roboform can also remember user IDs and passwords. You can automate that phrase using a bit of free software called AutoHotKey.
Then all you have to do every time you want to enter, say, the first line of your address, is press 'Alt' and '4', and like magic the words '29 Acacia Road' appear in the form. To do this, you need to write a 'script', a plain text file with personalised instructions for the program. This sounds uber-nerdy, but it's actually pretty simple. Once you've installed AutoHotKey, open a basic plain text file in Notepad. Huge thanks to VelvetGlove for writing this script. Each line in the file creates a different action.
For example putting '. Once the plain text file is edited, save it on your desktop, and be sure to end the file name with.That will add an edge to things. Lawro is going for a 2-1 United win - do you agree. You can make your own predictions now, take on Lawro and other fans, create your own league and try to make it to the top of the table by playing the new-look BBC Sport Predictor game. Lawro scored 80 points in week 15, which meant he slipped to 3,915th place out of more than 280,000 users.
He will be making a prediction for all 380 top-flight games this season, against a variety of guests. Osman, who supports Fulham and is a season ticket holder at Craven Cottage, did not end up with a score to match the aim of contestants that appear on his TV programme when he took on Lawro in April 2013 - he scored 100 points.
Media playback is not supported on this deviceA correct result (picking a win, draw or defeat) is worth 10 points. The exact score earns 40 points. Richard's prediction: This is a tough one to call. I like the way both teams play, and I think Leicester are coming back into a bit of form - especially Riyad Mahrez. It could be a good game. Media playback is not supported on this deviceYou can be the best attacking side in the world but if you can't defend on a given day against a good side, then you are always going to be in trouble.
Southampton came back to get a point against Bournemouth last week and I am going to go for another draw here.
I don't think Saints will test Arsenal's defence in the same way United did, but they won't give too much away at the back either. Richard's prediction: Ah, Arsenal. They win, they lose, they win, they lose. They are so inconsistent and I am trying to work out what they are due - a loss, I think - sorry Gunners fans.
This early spell is when Sam Allardyce usually has a big effect on results, but I think Liverpool might alter that statistic on this occasion. Media playback is not supported on this deviceBecause of their Europa League tie on Thursday, Allardyce will not have had much time to train with his squad, Everton ship a lot of goals and boy do Liverpool like scoring them at the moment.
The Reds record in front of goal is just staggering, as is the amount of chances they are creating at the moment too,It will not be one-way traffic - it is a derby, and I know what kind of games they are - but even if it is a lot tighter, I cannot see Liverpool making lots of chances without taking a couple of them.
Richard's prediction: I think this will be a cracking game - they always seem to be - and I think there will be a few goals. I am backing Liverpool to win it, because they are at home. I just think United have hit a run of form, and their win at Arsenal last week was very comfortable and impressive.
If Kompany is missing, that will give United more opportunities from set-pieces and, although City will create plenty of chances themselves, David de Gea is obviously in such fine form in goal for Jose Mourinho's side.
The key will be what Mourinho tries tactically. You know he will have a plan, and he will have had a team in mind for the past three or four matches too. So Pogba's suspension is a blow for him as far as that is concerned, but I just have a feeling United will go and beat City, in not a particularly good game.
Richard's prediction: City look absolutely unstoppable - what a pleasure it has been watching them this season. If anyone can stop them, it's Jose Mourinho, but I don't think that he can.Alternately, you can use black foam board to make the shadows deeper. Adding black foam board to the sides, just outside of the photo behind the product will create a dark edge on the white product. Combine a white bounce card on the front and black bounce cards behind the product for a more sophisticated lighting setup.
You can buy foam board on Amazon or at local drug store.
Keep in mind, this is just a white card, so you might be able to just balance a sheet of white printer paper or use a piece of poster board as well. Depending on the table you end up with, you can use tape or clamps to secure down your board so that it sweeps properly.
Being closer to the window will create a softer light with darker softer shadows. Being further away will give a more even light but with sharper lighter shadows. Place your table as close to the window as possible without intersecting the shadow from the windowsill. The closer you are to the window and the larger the window, the softer the light will be. You can try rotating the set so the window is at 45 degrees to the set, or try it with the window straight onto the set for a different style of lighting.
Food photography is often shot with a window behind the setup and the camera shooting into the window for a more dramatic setup.
Another variation is setting up in a garage with the door open, it will have the same qualities of light as a window, just without the glass.
You do not want direct sunlight hitting your set. Direct sunlight is harsh and looks bad on most people and products. There are a lot of ways to do this, but the ultimate goal is to have your mat board sweep from being flat on your table to being vertical. You may need to roll up the board to help it reach that shape.
In my set-up, we placed the table against the wall and taped the sweep to the wall and the table. Some bricks or a wooden block would work well. Place your product in the center on the flat part of the sweep and leave enough room to sneak your white reflector card in later. Set it to raw if you have it. This file is the largest file the camera can shoot, and utilizes the full bitdepth of the camera.
In my canon there are 2 settings to look out for:Set your ISO to 100: The ISO controls the sensitivity of the sensor. The higher the ISO the more noise there is. Typically, the lowest ISO you can set your camera to is ISO 100, so set it there if you can. Option A: Set your camera to Manual (M)This is the best setting for this type of work because nothing will be moving or changing as you take the pictures.
Preview the image on the back of the camera through liveview. Everything is probably pretty dark, which is ok. Now, switch to your shutter speed and rotate the dial to make it bright enough that the image is properly exposed.
Your shutter number should be going down. These are fractions of a second that your shutter will be open for and as the number lowers it will let more light in. Adjust this number until the preview of the image is correct.You export a SavedModel in your trainer. A model is an organizational tool that you can use however it makes sense for your situation.
It is common, especially after you have a version in production, to keep the inputs and outputs the same between model versions. This enables you to switch versions without needing to change other application structure you may have built around your model.
It also makes it easy to test new versions with existing data. If you request predictions specifying just a model name, Cloud ML Engine uses the default version for that model. Note that the only time the service automatically sets the default version is when you create the very first one. You can manually make any subsequent version the default by calling projects. This enables you to, for example, use a stable default version to serve predictions in production while testing newer versions without creating a dedicated model resource for testing.
There are no rules for names beyond those technical requirements, but here are some best-practices:The Cloud ML Engine quota policy sets a limit of 100 models per project and limits the total number of versions (combined between all models) to 200.
Cloud ML Engine needs some information to create your model version. You also have some options you can configure. This section describes the parameters of both types. These parameters are defined in the Version object or added for convenience in the gcloud ml-engine versions create command. You can specify the number of training nodes to keep running for your model version.
See the section on scaling for more information. If you are using the gcloud command-line tool to deploy your model, you can use a SavedModel on your local computer.
The tool stages it in the Cloud Storage location you specify before deploying it to Cloud ML Engine. You may have included TensorFlow Ops in your computation graph that were useful primarily in the context of training. Once you've trained your model, you can remove those ops from your graph before exporting your final version.
