Serving autocomplete suggestions fast!

Autocomplete (also known as live suggestions or search suggestions) is very popular with Search applications. It is generally used to return either query suggestion (à la Google Autocomplete) or to propose existing search results (à la Facebook).

Open source search platforms like Solr and Elasticsearch support this feature. Both allow for implementing autocomplete using edge n-grams. N-grams are subsets of words. Edge n-grams are subsets from one edge of a word (generally the beginning). For example, the edge n-grams of the word search are s, se, sea, sear, searc and search. The general principle when using them to support autocomplete is to index all those n-grams in the search index with the original word stored as is. When the user starts typing a word, we send what is typed so far as a query to the index containing the n-grams. For example, if we send the query sea, the index should return the word search as sea is an n-gram of this stored word.

This technique is very flexible as it allows for easy implementation of interesting functionalities, such as fuzzy search and infix matching. You can already find detailed instructions on how to implement the edge n-grams technique around the Web. For example, you can read this popular tutorial by Jay Hill to implement it in Solr, and this one by Jon Tai for Elasticsearch.

The Truth About Prenatal Supplements: 5 Things You Should Know | Forté Elements

Prenatal supplements come in many varieties. Some are one-a-day and some are chewable, powder, or even liquid.

However, the great variety of prenatal supplements manifests in the supplement facts. The traditional approach to prenatal vitamins is often market driven rather than science driven. This approach often produces supplements that lack essential nutrients because one pill is often more marketable than multiple pills. Many supplement companies are under the impression that something is better than nothing. However, as stated above, this approach results in the exclusion of nutrients or incorrect dosages.

When choosing a prenatal supplement, take into consideration these three differences:

Doses

Just because your prenatal contains a needed ingredient doesn't mean it contains the needed amount. A poignant example is the use of calcium.

According to recent research, women who are pregnant should receive 1,000mg a day of calcium to have the most effective results in reducing preeclampsia. However, though this is the recommended amount, many prenatal supplements only contain 250-500mg of calcium. If 1,000mg is the standard, 250-500mg should be nearly as good, right? Wrong. Doses less than 1,000mg show little to no effect on preeclampsia rates.

The nutrients that help prevent pregnancy complications and support your developing baby are most effective when taken in the right dosages. When examining the supplement facts, make sure to check the doses. Considering all the nutrients needed to support a healthy pregnancy, one pill may not be enough to support you and your baby.

Ingredients

While most prenatal supplements contain some nutrients needed during pregnancy, many contain unnecessary filler ingredients. And even the "non-filler" ingredients are often of poor quality or synthetic. The cheaper forms of vitamins and minerals take longer to absorb into the body, rendering them less useful.

If you are concerned about the quality of ingredients in your prenatal, research the supplement brand and consult with your physician.

Purpose

What is the purpose of your supplement? Is a healthy pregnancy for you and your baby the end-all goal? If the ingredients in your supplement do not match your needs, your health may not be at the center of the brand.

Make sure that your pregnancy and baby are not an afterthought. Your prenatal needs to be specifically tailored to your increased nutritional demands. Consulting with a physician and researching what your body needs will help you find a quality supplement.

Does my baby need to take vitamins? | BabyCenter

In most cases, breast milk or formula provides just about everything a baby needs for the first four to six months. The exception is vitamin D, which is recommended as a supplement for breastfed babies and babies who drink less than 32 ounces of formula per day. (See below for more details.)

After age 4 to 6 months, as your baby's diet gradually changes from an all-liquid diet to one that contains more and more solid food, your doctor may or may not recommend additional vitamin supplements.

Babies who eat a variety of foods over time shouldn't need them, but there are exceptions. For example, supplements may be necessary if your baby was born prematurely, at a low birth weight, or small for gestational age; consistently drinks less breast milk or formula than other babies his age and doesn't make up the difference with food: or has chronic health problems that affect his ability to eat. Be sure to ask your baby's healthcare provider if you have special concerns.

Your own health picture may come into play too. For example, women who have had gastric bypass surgery or who take certain medications daily may absorb fewer nutrients. This can reduce the nutrient content of their breast milk.

If you follow a vegan diet, tell your baby's healthcare provider. Vitamin B12, iron, zinc, calcium, and omega-3 fatty acids are nutrients that vegan moms and babies may need to make an extra effort to consume through diet or a multivitamin-mineral supplement.

DHA & Kids: A Smart Supplement | Parenting

6 months to 2 years

Benefit: DHA jump starts the production of a hormone that's crucial for brain development during this time of rapid growth.

How much: 100 mg daily or more from foods marked DHA-enriched, like some yogurt, cereal, and -- once your child turns 1 -- milk and eggs. And serve wild Alaskan salmon, the best natural food source that's also low in mercury. Up to four 1- to 2-ounce servings a week is safe.

Kids 2 to 5 years

Benefit: Low levels of DHA in children have been linked to an increased risk of ADHD, vision problems, and depression.

宝宝8个月需要补充哪些营养_亲子百科_太平洋亲子网

宝宝看到大人吃东西时会流口水，而且会挥手表示要拿，或者在大人吃饭时哭叫不已，表示也想尝尝，这就到了宝宝需要添加辅食的重要时期。

1. 热量：这个时期的宝宝的体重如果大幅度增加，80%是摄取了过多的热量，如果宝宝很瘦小或发育很慢，很可能是热量不足。宝宝所需的热量开始大半从母乳或奶粉中摄取，后逐渐转变为从固体食物中摄取。

2. 蛋白质：肉、鸡、鱼以及豆腐里都含有优质蛋白质，可以把这些做成宝宝能吃的食物喂给宝宝，但一次不要太多，应给宝宝调剂着吃。

3. 谷类和其他碳水化合物：一天给宝宝吃2～4匙的谷类食品，就能提供给宝宝基本的维生素、矿物质及蛋白质。谷类食物中有全谷类麦片、米片、粥或面条等。

4. 水分：不要因为母乳或奶粉量的递减而减少宝宝对水分的摄取，尤其在夏天，更要多喂水或稀释过的果汁。

Write it like Riak; Query it Like Solr – Basho

In a land where many open source full-text search solutions exist, it is important to identify what makes Riak Search unique against the competition. One important answer to that question is Riak's Active Anti-Entropy (better known as keeping your search indexes fresh, over time, as data is manipulated in Riak).

Many real world applications offer search functionality against a subset of record attributes by passing them along to a full-text search engine. Meanwhile, the source of truth for those records remains in a database.

As an example, consider an Oracle instance that contains your entire product catalog. Next to that Oracle database may be an instance of Solr that indexes only the titles and descriptions columns of your products table. This setup allows users to search freely against those fields on your site.

Stupid Lucene Tricks: Exact Match, Starts With, Ends With | Mark Leighton Fisher [blogs.perl.org]

"Starts With" and "Ends With" searches are an extension of this technique, as a "Starts With" search just requires adding the delimiter in front of your search term (like using "lucenematch Acer" when searching for terms starting with "Acer"). Similarly, "Negundo Ab lucenematch" will search for terms ending in "Negundo Ab".

.To make it easier for your users, you could:

Define '^' as the first character of a search phrase meaning "Starts With".
Define '$' as the last character of a search phrase meaning "Ends With".
Pre-parse your search phrase, substituting '^' and '$' appropriately.

solr - SolrJ not setting request handler - Stack Overflow

It's true that the visible effect in the "setRequestHandler" method is to just set the qt parameter. But that's not the end of the story with SolrJ.

When a SolrJ request is processed, if the qt parameter contains a string starting with a forward slash, SolrJ will change "/select" in the URL path to the value contained in that parameter before it sends the request to Solr. It will also send the qt parameter as-is to Solr, but the parameter itself usually doesn't matter.

If you send an actual request to Solr on the /select handler with qt set to "/all", Solr should ignore the qt parameter -- unless you set handleSelect to true in the requestDispatcher section of the solrconfig.xml. This is not recommended -- because it means that you can change the index through the /select handler, simply by setting qt to "/update".

Cross Domain Ajax with Cookies support using jQuery

Ajax requests are only possible when the protocol, domain and port number are the same. But sometimes you want to do Ajax calls to a different domain for example when you are creating a shared service that people should be able to call using Ajax or when you are developing locally and you are testing on a remote server. There are multiple ways to get around this restriction for example by using CORS, an iFrame or JSONP. In my last project I got around the restriction using JSONP, so I will explain that here. See links for more information about solving it using CORS.

javascript - Cross domain POST request is not sending cookie Ajax Jquery - Stack Overflow

You cannot set or read cookies on CORS requests through JavaScript. Although CORS allows cross-origin requests, the cookies are still subject to the browser's same-origin policy, which means only pages from the same origin can read/write the cookie. withCredentials only means that any cookies set by the remote host are sent to that remote host. You will have to set the cookie from the remote server by using the Set-Cookie header.

java - Removing tail of X elements from a List - Stack Overflow

subList(list.size() - N, list.size()).clear() is the recommended way to remove the last N elements. Indeed, the Javadoc for subList specifically recommends this idiom:

This method eliminates the need for explicit range operations (of the sort that commonly exist for arrays). Any operation that expects a list can be used as a range operation by passing a subList view instead of a whole list. For example, the following idiom removes a range of elements from a list:
 list.subList(from, to).clear();

Indeed, I suspect that this idiom might be more efficient (albeit by a constant factor) than calling removeLast() N times, just because once it finds the Nth-to-last node, it only needs to update a constant number of pointers in the linked list, rather than updating the pointers of each of the last N nodes one at a time.

@Data

@Data is a convenient shortcut annotation that bundles the features of @ToString, @EqualsAndHashCode, @Getter / @Setter and @RequiredArgsConstructor together: In other words, @Data generates all the boilerplate that is normally associated with simple POJOs (Plain Old Java Objects) and beans: getters for all fields, setters for all non-final fields, and appropriate toString, equals and hashCode implementations that involve the fields of the class, and a constructor that initializes all final fields, as well as all non-final fields with no initializer that have been marked with @NonNull, in order to ensure the field is never null.

@Data is like having implicit @Getter, @Setter, @ToString, @EqualsAndHashCode and @RequiredArgsConstructor annotations on the class (except that no constructor will be generated if any explicitly written constructor exists). However, the parameters of these annotations (such as callSuper, includeFieldNames and exclude) cannot be set with @Data. If you need to set non-default values for any of these parameters, just add those annotations explicitly; @Data is smart enough to defer to those annotations.

All generated getters and setters will be public. To override the access level, annotate the field or class with an explicit @Setter and/or @Getter annotation. You can also use this annotation (by combining it with AccessLevel.NONE) to suppress generating a getter and/or setter altogether.

All fields marked as transient will not be considered for hashCode and equals. All static fields will be skipped entirely (not considered for any of the generated methods, and no setter/getter will be made for them).

If the class already contains a method with the same name and parameter count as any method that would normally be generated, that method is not generated, and no warning or error is emitted. For example, if you already have a method with signature equals(AnyType param), no equals method will be generated, even though technically it might be an entirely different method due to having different parameter types. The same rule applies to the constructor (any explicit constructor will prevent @Data from generating one), as well as toString, equals, and all getters and setters. You can mark any constructor or method with @lombok.experimental.Tolerate to hide them from lombok.

Automatically format and cleanup code every time you save | Eclipse On E

Eclipse has a wonderful feature that formats according to your coding standards. It handles things like indentation, where curly braces are placed, if blank lines should occur between field declaration and hundreds of other options.

However, to invoke this formatting, you have to tell Eclipse to do this every time you've edited the code. You can do this using Ctrl+Shift+F but (1) you have to do that every time and (2) you have to remember to do it in the first place (and we all know how good developers are at remembering things).

Working with lombok and eclipse cleanup fails: "A save participant caused problems." · Issue #879 · rzwitserloot/lombok

I'm not the developer, but I looked into the code a little bit and it looks like this will be a mess to fix. Essentially, the Eclipse developers changed the way that they do code formatting. The new method doesn't take into account that the code compiled doesn't match the code written. With lombok, however, that assertion is incorrect. I suspect that fixing it would require a decent overhaul of how lombok works with eclipse—probably a huge effort. Add to that eclipse doesn't provide a nice API to help the cause, the same scenario is likely to play out again at a random time in the future.

Find the highest occurring digit in prime numbers in a range - GeeksforGeeks

Given a range L to R, the task is to find the highest occurring digit in prime numbers lie between L and R (both inclusive). If multiple digits have same highest frequency print the largest of them. If no prime number occurs between L and R, output -1.

Input : L = 1 and R = 20.  Output : 1  Prime number between 1 and 20 are 2, 3, 5, 7, 11, 13, 17, 19.  1 occur maximum i.e 5 times among 0 to 9.

We strongly recommend you to minimize your browser and try this yourself first.

The idea is to start from L to R, check if the number is prime or not. If prime then increment the frequency of digits (using array) present in the prime number. To check if number is prime or not we can use Sieve of Eratosthenes.

Checking Account Details

Pending Transactions The Date column on your Account Activity page shows pending transactions that have not yet posted to your account (reflected with a date of "Pending"), as well as items that have been posted (reflected with the post date, e.g., 07/11/2011). To understand the difference between the two, it's helpful to review the posting process. When you use a debit card to pay a merchant, or you initiate a deposit, withdrawal or transfer to your account, you authorize the transaction amount. These transactions will not be posted to your account until the bank receives and processes them. For most merchant transactions, the merchant knows the exact amount of the transaction and asks you to authorize that amount. For example, if you buy $82.75 worth of groceries, the market would ask you to authorize an $82.75 charge or debit to your account. That amount would then appear as a pending transaction on your Account Summary until it was posted. Sometimes, though,

Don't bring you shortcuts with you – Hadi Hariri

It's a good point. When switching from one tool to another, often having familiar shortcuts help us get up to speed faster.

In IntelliJ IDEA we also have keyboard mappings for Eclipse, but when people ask me about it, I usually recommend they don't use it.

Why? Because I don't think it works. At least not in the long run.

The issue is that IntelliJ IDEA and Eclipse work differently in quite a few ways. When someone comes to IntelliJ IDEA from Eclipse, using the keyboard shortcuts they're accustomed to, they normally feel productive straightaway, but often that starts to turn into frustration, because suddenly a few shortcuts are missing or don't behave exactly the same way they'd expect it to in Eclipse.

Paid time off - Wikipedia

Paid time off or personal time off (PTO) is a policy in some employee handbooks that provides a bank of hours in which the employer pools sick days, vacation days, and personal days that allows employees to use as the need or desire arises. This policy pertains mainly to the United States, where there are no federal legal requirements for a minimum number of paid vacation days (see also the list of statutory minimum employment leave by country). Instead, U.S. companies determine the amount of paid time off that will be allotted to employees, while keeping in mind the payoff in recruiting and retaining employees. In the United States, paid vacation is typically two weeks or less per year for the first few years of employment in addition to roughly 10 paid federal holidays.^[1]

This Chinese Billionaire Is Moving Production to the U.S. to Cut Costs | Fortune.com

Updated: 7:42 PM UTC While it has been said for a long time that the U.S. is bleeding manufacturing jobs overseas, particularly to China, some businesses have been moving operations the other way round . And now, the head of a leading Chinese glass maker making the same move has openly questioned if his country really is such a lucrative destination for offshore factories, reports Hong Kong newspaper the South China Morning Post. "Overall speaking, the tax burden for manufacturers in China is 35% higher than in the U.S.," Cao Dewang told China Business Network in an interview . He added that a combination of cheap land, reasonable energy prices and other incentives means that, despite higher manufacturing costs, he can still make more money by making glass in the U.S. than by exporting Chinese-made panes to the U.S. market. His company, Fuyao Glass, has invested over $1 billion stateside, according to the Post, the most significant move of which is opening its U.S.

Spanish football expert claims Real Madrid will make huge bid for Lionel Messi, fans react - LE BUZZ

0 Shares It seems the most ridiculous transfer report of the year – and that's really saying something – but Spanish football expert Graham Hunter has really got some people concerned by claiming that Real Madrid will make a bid to sign Lionel Messi. It's not the first time that the Barcelona superstar has been linked with a move to Real Madrid, but that is usually from one of the tabloids screaming that a sensational move could be in the offing. This time, however, the report comes from a journalist held up as a Spanish football expert, and he really does try to make the case in his Daily Record column that Real Madrid will genuinely attempt to sign Messi. "Whether you consider that Florentino will succeed … or be laughed out of court, the Real Madrid President almost has no option but to try one last shot at tempting Messi to cross the divide. "My firm opinion is that not only will Messi refuse to contemplate betraying a club about whom he's always said "I owe everything to",

How to Find Costco Clearance Items | Costco Insider

Did you know there's a secret trick to finding Costco clearance items? It's true and we're going to explain to you how to find these Costco markdowns. It all begins by looking at the item price tag. You want to look for items that have a price ending in .97 cents. This is the only way to know it's on clearance. There's no special red price tag that's marked clearance and there's no clearance section with all the marked-down items. Essentially the markdown blends in with all other store items. So, now that we know this little trick we walk through the aisles of the Costco store looking at all the price tags to see which items are clearanced.

There's a few other things to note about clearance items at Costco. First of all, right below the $*.97 price will be a date printed on the price tag. This tells you when the sign was printed, which gives you a good idea of the last time the item was marked down. Secondly, you can also look at the top right corner of the price tag to see if there's an asterisk. If there's an asterisk that means what you see is the last of the item, there are no more pallets on the shelves. If there's not an asterisk that would be an indication that you might want to wait to buy the clearanced item until it's marked down further, because there's still a lot on hand. In that case we'll watch the item over a few weeks to see if the price drops down further, as long as there is still a lot on hand. But, be careful, sometimes the store will return all the items to the manufacturer all of a sudden or liquidate the remaining stock and you'll miss out on the clearanced price all together.

Eclipse Activator startup sins – Tracing the startup time | vogella blog

Inspired by the Eclipse start optimisation by Alex Blewitt post, I traced my environment and reworked our Eclipse Tracing tutorial section to enable others to do the same.

On my machine starting the Eclipse IDE (with only the SDK, XML editor and Git installed) takes 4317 ms. Looking at the "bad" guys it looks like Eclipse could start approx. 18 % faster if PDE and JDT would not activating themself. If opened Bug for JDT core and Bug for PDE.

If case you experience long startup time in your setup, I recommend to turn on the tracing option and if you see a slow starting component, to open a bug report or code correction for it. In most cases removing the activator (and moving its logic to another place which is lazy initialized) should speed up the start process.

5 steps to speed up your eclipse as a super fast IDE | David Euler on coding and design

Follow these steps to speed up your eclipse as a super fast IDE , it works for 32 & 64 bit version eclipse/jdk on my windows 7 x64.

1.Disable antivirus software, or add your jdk & eclipse & workspace & other related folder to white list in your antivirus software.

2.Disable unecessary validations and startup action in eclipse reference.

For validations: on eclipse menu Windows -> Preferences -> Validation, click "Disable All", and then select the validator which you need. I selected "Classpath Dependency Validator" only.

For startup action: on eclipse menu Windows -> Preferences, type "startup", select "Startup and Shutdown", untick the options you don't need. (Thanks for David's suggest, I've added the above 2 detail steps for readers)

3.Modify eclipse.ini to set the Xmn(new generation size), Xms and Xmx, enable parallel GC
-vm
C:/jdk1.6.0_25/bin
-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
–launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.100.v20110502
-product
org.eclipse.epp.package.jee.product
–launcher.defaultAction
openFile
–launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
–launcher.XXMaxPermSize
256m
–launcher.defaultAction
openFile
-vmargs
-server
-Dosgi.requiredJavaVersion=1.5
-Xmn128m
-Xms1024m
-Xmx1024m
-Xss2m
-XX:PermSize=128m
-XX:MaxPermSize=128m
-XX:+UseParallelGC

4.Create a ram disk(virtual disk) on memory, and put your jdk on the ram disk.
You can use imdisk to create ram disk. Firstly download it from: http://www.ltr-data.se/opencode.html/#ImDisk, and install it.

Then set the ImDisk driver to auto-load at Command Prompt with administrative privileges (for example right-click, start as Administrator), type:

sc config imdisk start= auto
net start imdisk

create a 200m ram disk as driver n by:
imdisk -a -t vm -s 300m -m n:

then you should format the ram disk manually.

later ,if you would like to remove the ram disk, just run the command:
imdisk -D -m n:

5.Make sure you are using sun jdk, not open jdk/gcj nor other jdk on linux.
If you are not satified with the after the above steps, install jrockit instead of sun jdk, and change some of the vm options by jrocket specification,
jrockit is faster than sun jdk.

做技术合作：本田宣布与谷歌无人车公司正式谈判_网易科技

网易科技讯12月22日消息，据路透社报道，本田汽车周三表示与谷歌母公司Alphabet的自动驾驶部门Waymo举行正式谈判，准备在自己的汽车上安装自动驾驶技术，可能成为该自动驾驶软件的第二个客户。谷歌在一周前刚剥离自动驾驶部门，成立新的公司Waymo。

这份潜在协议说明汽车制造商在面临高昂的新技术开发成本时出现分裂，一部分还是自己开发技术如福特和通用，而另一些公司转向与供应商合作分摊成本。本田的声明标志着谷歌的自动驾驶技术有了第二个潜在客户。今年五月菲亚特克莱斯勒曾与谷歌达成协议，在微型旅行车上安装谷歌的技术。

After Uber defied California's DMV, the DMV revoked Uber's registrations | Ars Technica

Stay logged in Cars Technica — After Uber defied California's DMV, the DMV revoked Uber's registrations Uber said it remains "100 percent committed to California" but will test elsewhere. Dec 22, 2016 2:10 am UTC If these people are in California, this is not a self-driving Uber with an engineer up front. UberPop On Wednesday night, the California DMV issued a statement saying it would revoke the registrations of 16 cars owned by Uber, which the company had been using to test its self-driving system. The DMV said that "the registrations were improperly issued for these vehicles because they were not properly marked as test vehicles." The move from the California DMV comes after a contentious public battle last week, when Uber suddenly announced the launch of its pilot program in San Francisco (the same program had been running in Pittsburgh for a few months already). But Bloomberg noted that the ride-hailing company still hadn't registered with the state's DMV ,

How do you clear Apache Maven's cache? - Stack Overflow

Have you checked/changed the updatePolicy settings for your repositories in your settings.xml.

This element specifies how often updates should attempt to occur. Maven will compare the local POM's timestamp (stored in a repository's maven-metadata file) to the remote. The choices are: always, daily (default), interval:X (where X is an integer in minutes) or never.

How do you clear Apache Maven's cache? - Stack Overflow

To clean the local cache try using the dependency plug-in.

mvn dependency:purge-local-repository: This is an attempt to delete the local repository files but it always goes and fills up the local repository after things have been removed.
mvn dependency:purge-local-repository -DreResolve=false: This avoids the re-resolving of the dependencies but seems to still go to the network at times.
mvn dependency:purge-local-repository -DactTransitively=false -DreResolve=false: This was added by Paweł Prażak and seems to work well. I'd use the third if you want the local repo emptied, and the first if you just want to throw out the local repo and get the dependencies again.

Cleaning Maven m2e .cache directory - Stack Overflow

In contrast to the other answers, make sure to keep .m2/*.xml (your settings) and .m2/repository (not strictly necessary to keep, but Maven will have to download half the Internet again).

Now, as for that .cache folder: if you open Eclipse, M2Eclipse will sometimes run a job akin to "Downloading repository indexes". These indexes allow you to quickly find an artifact using M2E's "Add dependency" wizard if you only know (part of) its artifact id. It needs to put the downloaded index files somewhere, and according to http://dev.eclipse.org/mhonarc/lists/m2e-users/msg02486.html the .cache folder is where they go:

OptaPlanner - What is the fastest Garbage Collector in Java 8?

There is a proposal to make G1 the default Garbage Collector in OpenJDK9 for servers. My first reaction is to reject this proposal:

G1 is 17.60% is slower on average.
G1 is consistently slower on every use case for every dataset.
On the biggest dataset (Machine Reassignment B10), which dwarfs any of the other datasets in size, G1 is 34.07% is slower.
If the default GC differs between developer machines and servers, then developer benchmarks become less trustworthy.

On the other hand, there are a few nuances to note:

G1 focuses on limiting GC pauses, instead of throughput. For these use cases (with heavy calculations) GC pause length mostly doesn't matter.
This was an (almost) single threaded benchmark. Further benchmarking with multiple solvers in parallel or multi-threaded solving might influence results.
G1 is recommended for a heap size of at least 6 GB. This benchmark used a heap size of only 2 GB and even that size is only needed for the biggest dataset (Machine Reassignment B10).

Heavy calculations is just one of the many things that OpenJDK is used for: it's just 1 stakeholder in this community wide debate. If other stakeholders (such as web services) prove otherwise, maybe it's worth changing the default GC. But show me the benchmarks on real projects first!

What being cloud-native really means | InfoWorld

You hear this everywhere these days: Build applications that are cloud-native -- that is, developed specifically for cloud platforms. The trouble is, everyone has his or her own definition of "cloud-native." As a result, cloud-hosted applications are all over the place in their use of native features. Many are not designed properly, and they're worse off in the cloud than when they ran in the data center.

Cold-start Recommendations | Martin Saveski

Recommender systems suggest to users items that they might like (e.g., news articles, songs, movies) and, in doing so, they help users deal with information overload and enjoy a personalized experience. One of the main problems of these systems is the cold-start, i.e., when a new item or user is introduced in the system and no past information is available, no effective recommendation can be produced. The cold-start is a very common problem in practice: modern online platforms have hundreds of new items and millions of visits from logged-out users every day. Despite the importance of this problem not many solutions have been proposed in the literature. We contribute to closing this gap by studying whether it could be overcome without sacrificing performance. We do so by exploiting two aspects: the combination of the content and collaborative information, and the users' location.

Dealing with the new user cold-start problem in recommender systems: A comparative review

The Recommender System (RS) is an efficient tool for decision makers that assists in the selection of appropriate items according to their preferences and interests. This system has been applied to various domains to personalize applications by recommending items such as books, movies, songs, restaurants, news articles and jokes, among others. An important issue for the RS that has greatly captured the attention of researchers is the new user cold-start problem, which occurs when there is a new user that has been registered to the system and no prior rating of this user is found in the rating table. In this paper, we first present a classification that divides the relevant studies addressing the new user cold-start problem into three major groups and summarize their advantages and disadvantages in a tabular format. Next, some typical algorithms of these groups, such as MIPFGWC-CS, NHSM, FARAMS and HU–FCF, are described. Finally, these algorithms are implemented and validated on some benchmark RS datasets under various settings of the new user cold start. The experimental results indicate that NHSM achieves better accuracy and computational time than the relevant methods.

A Unified Approach to Building Hybrid Recommmender Systems - Microsoft Research

Content-based recommendation systems can provide recommendationsfor "cold-start" items for which little or no training data is available, but typically have lower accuracy than collaborative filtering systems. Conversely, collaborative filtering techniques often provide accurate recommendations, but fail on cold start items. Hybrid schemes attempt to combine these different kinds of information to yield better recommendations across the board.
We describe unified Boltzmann machines, which are probabilistic models that combine collaborative and content information in a coherent manner. They encode collaborative and content information as features, and then learn weights that reflect how well each feature predicts user actions. In doing so, information of different types is automatically weighted, without the need for careful engineering of features or for post-hoc hybridization of distinct recommender systems.
We present empirical results in the movie and shopping domains showing that unified Boltzmann machines can be used to combine content and collaborative information to yield results that are competitive with collaborative technique in recommending items that have been seen before, and also effective at recommending cold-start items.

This Alphabet Inc (GOOGL) Moonshot Could Become Its Own Company | InvestorPlace

As consumers look toward the skies, investors should look toward GOOGL By Chris Katje , InvestorPlace Contributor | Dec 21, 2016, 5:45 am EST Alphabet announced plans to create an online exchange named "Wing Marketplace" that would allow customers to get deliveries from selected retailers and restaurants. Drone deliveries aren't new, but they have not been officially approved in all 50 states. Alphabet is but one of several companies that has tested drone deliveries and showcased its successful launches, but it's also highlighted possible concerns. An announcement like this isn't usually that exciting. However, Alphabet named two companies that are actively looking at using this service, which would give the GOOGL Wing project a huge tailwind. Both Whole Foods Market, Inc. (NASDAQ: WFM ) and Domino's Pizza, Inc. (NYSE: DPZ ) are considering using this service in some capacity. While they have already declined to sign on due to concerns over the user experience,
