We Asked Five Security Experts If Smart Locks Are Ever Safe. An automatic firmware update broke Lock. States internet enabled smart locks for around 5. Airbnb hosts who use the locks to remotely manage rental access. Customers have to replace their locks or ship them back for repairs. The locks can still be operated with a physical key. Smart locks, like so many Internet of Things devices, are vulnerable to a host of tech issues. Last year security consultant Anthony Rose revealed huge security flaws in Bluetooth enabled door locks. Of the 1. 6 locks he tested, Rose managed to break into 1. Smart locks dont seem any more foolproof than when our sister site Gizmodo explored smart lock security four years ago. We asked five security experts whether these locks are fundamentally insecure. A 36yearold Chinese national was arrested in Los Angeles this week in connection with a computer hacking conspiracy involving malware linked to the 2014 US Office. None of these experts is ready to entirely write off all smart locks. Like so much of technology, you simply have to decide who to trust and how much to trust them, says security technologist, author, and Harvard lecturer Bruce Schneier, who testified before Congress last year about the catastrophic risks of insecure internet enabled devices. There is always a risk that a net enabled lock will get bricked or hacked, says MIT professor Stuart Madnick, most likely due to the actions or carelessness of the owner. But he points out that old fashioned key and lock solutions have their own user created risks One of my popular sayings is You may buy a stronger lock for your door, but if you still leave the key under the mat, are you really any more secureMadnick compares the trade off to the increased risks of driving a car instead of a horse. Are you willing to trade your car in for a horseJeremiah Grossman, Chief of Security Strategy at cybersecurity firm Sentinel.
One, compares smart locks to older remote systems like prison security doors and receptionist controlled buzzers. He says internet connected locks can sometimes be an appropriate solution Would I personally entrust the security of my home to such a device Not at the moment, but in the future as the devices get better and more secure I might trust them more. Should others use them Sure, depending on their living situation. And people might consider using them for doorways where what theyre securing isnt critically important to them. Thats one hell of a caveat for a 4. Grossman recently tweeted about deeper implications of an insecure smart lock update system But Grossman says we shouldnt ask whether smart locks are fundamentally insecure but whether they are secure enough for a given application. Alan Grau, co founder of security software provider Icon Labs, puts it similarly There is no question people are going to use smart locks despite the risks. I think the questions to be asked are not if these solutions should be used, but rather what are the risksHow do these risks compare to traditional locks What can lock makers do to ensure that a reasonable layer of security is built into these devices Security reporter Brian Krebs had the harshest words, saying it bothers him that so many people are installing smart locks. To break through a lock, he says, an attacker has always had to be on site. With internet enabled locks, youve removed that expensive and from an attackers perspective, risky cost from the equation. He still wont write off the technology entirely. I am not saying there cant be remotely enabled locks that are also secure. But Id wager on balance that most of those in use today are probably nowhere near as secure as they should be. With all these caveats, the consensus seems to be that smart locks trade off a lot of expected security for more convenience. Before you buy a smart lock, research its known security issues, and know that new ones could crop up. But remember that if you use it wrong, any lock is insecure. Download Update. Star Update. Star.

Install Winch In Truck Bed . The TV ecosystem is just as bad, largely thanks to Amazons own selfish decisions.Amazon still hasnt released its promised Apple TV app, so Prime customers have to stream Transparent and Curb Your Enthusiasm from their phones.There are no plans for an Amazon app on the Chromecast, or for Spotify on Apple TV.You can retreat to a third party media player like Roku, but then you cant play videos purchased through i.Tunes without a wonky file conversion.Starting at the end of this month, Amazon will no longer sell the Chromecast or Apple TV.AndRead more Read.Meanwhile, Facebook runs around kind of integrating with all these other services while trying to push its own messaging and sharing platforms, and burying every post that dares link to You.Tube or Twitter.As a customer choosing a phone, computer, and media player, youre stuck with three choices Buy into an ecosystem that inevitably has some crappy elements.You could choose Google, and miss out on Apples slick interface and seamless desktop to mobile integration.Or choose Apple, lose a lot of third party functionality, and get locked into increasingly bizarre design choices your Lightning headphones wont work on your laptop and inferior software like Apple Maps, Mail, and Calendar.On desktop, choose Windows and miss out on that same integration, or choose Apple, pay more for the same computing power, and get your computer games a year late.Straddle ecosystems, running the Google Suite instead of MS Office and hooking your i.Phone up to your PC or your Android to your Mac.Run Spotify, buy an Echo, and live with their limited capabilities.Maybe even run Excel on OS X.All but the most basic users reach outside their main ecosystem at some point.Install Linux on your Chromebook, jailbreak your i.Phone, run Cortana on your Fit.Bit, hack your Echo to play Tidal, and write a viral Medium post encouraging people to unplug.In the short term, all these companies have good reasons to lock up their platforms wherever they still think they can steal market share from the others, and wherever they would rather focus resources on improving their own service instead of handing millions of customers to their competitors through a partnership.But in the long term, this lock in keeps the Big Five from innovating, their products leaning on the crutch of the ecosystem, alienating customers who will then abandon the ecosystem for third party services like Spotify, Dropbox, Whats.App, 1.Password, and Overcast.OS has a bunch of great podcast managers these days, but after testing all of them, our favoriteRead more Read.Historically, these ecosystems tend to open up, making way for the next battle.Macs and PCs didnt always run so many of the same apps.Internet Explorer and Netscape were much more mutually exclusive than Chrome and Safari.And for a while, your Internet came in flavors of AOL, Prodigy, or Compu.Serve.Even Android and i.OS used to have zero apps in common.But each time, interoperability won out, bringing most of each platforms strengths to everyone.But things could get worse before they get better.The Big Five are all racing to win at online payments, wearables, AI, AR, VR, smart homes, smart cars, and the growing Internet of Things.And as long as each company thinks it can win, it will try to push out the others instead of playing nice.Eventually there will be winners and losers, or decentralized cooperation.Every now and then, a new protocol will open up thats as decentralized as email or HTTP.And the giants of the day will move onto a new fight.In the meantime, theres nearly always some way to force the ecosystems to play together, at the expense of simplicity and not having your shit constantly break.Theres always some third option to jimmy into the gap and outperform all the defaults.And thats what Lifehackers all about.How to install Android apps to your SD card by default.From the moment I walked into PC Richard and Son, I was greeted by a swarm of officious salesmen with kinetic personalities and avaricious appetites.These guys were hopeless to make a sell they saw me as a delicious meal on a plate lined with credit cards and would stop at nothing to secure a deal.I briskly walked pass these guys and made my way to the file storage section.After all, I came here for one purpose I wanted to augment the storage in my phone with a 3.GB micro.SD card.The integrated device storage simply wasnt sufficient to quell my insatiable cravings for hi res photos, HD videos and lossless audio.When the proverbial belly of my Galaxy S4s distended until it wasnt able to eat any more media, thats when I knew I needed to upgrade.The problem.So I purchased the card, tore open the box and popped it into my phone.Microsoft Odbc For Oracle Version 4 on this page.You can confirm your Galaxy S4 detects the memory card by Swiping down from the top of the screen with your index finger.Tapping the Settings cog.Touching the More tab and then flicking down to Storage.In addition, I suggest touching Format SD card on new SD cards before trying to save stuff to them.Obviously, the time needed to format your SD card is contingent on its size however, it shouldnt last longer than a few minutes.After I had my card in place, I thought every app I installed in the future would automatically save itself to the SD card.I was wrong.In addition, I couldnt figure out how to move my existing apps over to the SD card.In this guide, Im going to show you how to move your apps over to the SD card and also change the behavior of your phone so that it saves new apps there by default.Keep in mind that you shouldnt move every app just because you can.I suggest restricting the move to apps that are consuming the most space on your phone.The easy way.The simplest way to evict apps from the device to your SD card is to open the Application Manager.Youll find it lurking under the More tab in Settings.Inside the Application Manager, swipe to the left once to view a list of all the apps that you can kick to the card.Apps with green checkmarks are already on the SD card so well ignore these guys for now.Were looking for the most gluttonous apps without a checkmark.Once you find the fatty app, tap it open and choose the Move to SD card button.The slightly harder way.If the app you want to move isnt showing up here then we need to do a few things Enable USB Debugging on the phone.Install Googles Android SDKOracles Java SDKPlug in the Galaxy S4.I know it sounds like a laborious list of steps but if you follow my lead it wont be so bad.Turn it on, thats what she saidFirst we need to turn on USB Debugging.USB debugging is a tool developers use to allow an Android phone to communicate with a computer running the Android Software Development Kit SDK.When developers start crafting new apps for droids they code them in the Android SDK and then save them to the phone via the USB debugging feature.But dont worry we arent doing any Android coding today we just need to enable USB debugging so we can gain access to lower level functions of the phone.In Settings, go to the More tab, scroll down and touch About phone.Youll see a bunch of stuff in here such as the Status, Legal Information and the Device name.There are also a few other settings which seem disabled because the font color is a dark charcoal color.Flick down until you see the Build number and keep tapping it vigorously until it unlocks the Developer mode.Now go back to the previous screen, you can tap the Back button which is immediately to the right of the Home button, then touch Developer options and pick USB debugging.Youll get an informational popup with a USB debugging synopsis.Just tap OK and youre good to go.Okay, were one third of the way there.Get Androids SDK and Oracles JDKGo ahead and grab the Android SDK.Its over a half a gigabyte so it could take a while to download the important thing is to make sure you get the right bit version.If youre not sure if your computer is a 6.OS, theres a slick command line trick that will tell you.Now snag the latest JDK and were ready to rumble.Install both SDKs keeping the defaults settings for both.I should mention that the Android SDK is a beast and takes a while to extract so get ready to apportion at least a half an hour for it to finish.Its worth it though think about all the storage youre about to reclaimOkay, now launch the SDK manager.A black window may immediately flash on the screen and disappear in the same instant.This is normal, the SDK manager is just waking up.He should load after about 1.There are numerous packages in here but our chief concern is that Android SDK Platform tools is checked.We need the tool in here called Android Debug Bridge ADB which well use to send commands to our phone.Click the Install packages button in the bottom right corner.A window will pop in your face about the license agreements.Who knows what youre actually agreeing to but if you dont accept you cant use the SDK.Grrr Cest la vieClick Accept License and acquiesce.The packages should star to download and extract themselves accordingly.If you get message about Android Tools being updated click OK to close the window.You down with ADB Yeah, you know me Okay, now its time to get down with ADB.Find the folder where you executed SDK Manager.Hold down the Shift key, then right click adb.Open command window here.Were about to get down and dirty with the command prompt but before we do we need to plug in the Galaxy S4 with the USB cable.You might suddenly see a pop up on your phone that says Allow USB debugging.It may read something like this This computers RSA key fingerbrint is something something blah blah.Just click OK.

Hibernate Interview Questions and Answers.Hibernate is one of the most widely used ORM tool for Java applications.Its used a lot in enterprise applications for database operations.So I decided to write a post about hibernate interview questions to brush up your knowledge before the interview.Whether you are fresher or experienced, having good knowledge or Hibernate ORM tool helps in cracking interview.Here I am providing important hibernate interview questions with answers to help you brush up your knowledge and impress your interviewer.Just like other interview questions posts, chances are that I will be adding more questions to this list in future, so you might want to bookmark it for future reference.Recently I have written a lot of posts on hibernate, most of them contains complete downloadable projects.I will provide reference to them as and when needed and you can go through them to refresh your knowledge.What is Hibernate Framework Object relational mapping or ORM is the programming technique to map application domain model objects to the relational database tables.Hibernate is java based ORM tool that provides framework for mapping application domain objects to the relational database tables and vice versa.Hibernate provides reference implementation of Java Persistence API, that makes it a great choice as ORM tool with benefits of loose coupling.We can use Hibernate persistence API for CRUD operations.Hibernate framework provide option to map plain old java objects to traditional database tables with the use of JPA annotations as well as XML based configuration.Hibernate Update Sql Query Example To Find' title='Hibernate Update Sql Query Example To Find' />the significant prevalence of SQL Injection vulnerabilities, and the attractiveness of the target i.Hibernate Update Sql Query Example To Find' title='Hibernate Update Sql Query Example To Find' />In this excerpt from Manning Publications Hibernate in Action, authors Christian Bauer and Gavin King introduce Hibernates core APIs and explain its basic.Hibernate first program hibernate hello world program, how to use hibernate insert command,insert query in hibernate, how to use hibernate insert query.Similarly hibernate configurations are flexible and can be done from XML configuration file as well as programmatically.For a quick overview of hibernate framework usage, you can go through Hibernate Beginners Tutorial.What is Java Persistence API JPA Java Persistence API JPA provides specification for managing the relational data in applications.Current JPA version 2.July 2.JSR 3.JPA 2. 1 was approved as final on 2.May 2.JPA specifications is defined with annotations in javax.Using JPA annotation helps us in writing implementation independent code.What are the important benefits of using Hibernate Framework Some of the important benefits of using hibernate framework are Hibernate eliminates all the boiler plate code that comes with JDBC and takes care of managing resources, so we can focus on business logic.Hibernate framework provides support for XML as well as JPA annotations, that makes our code implementation independent.Hibernate provides a powerful query language HQL that is similar to SQL.However, HQL is fully object oriented and understands concepts like inheritance, polymorphism and association.Hibernate is an open source project from Red Hat Community and used worldwide.This makes it a better choice than others because learning curve is small and there are tons of online documentations and help is easily available in forums.Hibernate is easy to integrate with other Java EE frameworks, its so popular that Spring Framework provides built in support for integrating hibernate with Spring applications.Hibernate supports lazy initialization using proxy objects and perform actual database queries only when its required.Hibernate cache helps us in getting better performance.For database vendor specific feature, hibernate is suitable because we can also execute native sql queries.Overall hibernate is the best choice in current market for ORM tool, it contains all the features that you will ever need in an ORM tool.What are the advantages of Hibernate over JDBC Some of the important advantages of Hibernate framework over JDBC are Hibernate removes a lot of boiler plate code that comes with JDBC API, the code looks more cleaner and readable.Hibernate supports inheritance, associations and collections.These features are not present with JDBC API.Hibernate implicitly provides transaction management, in fact most of the queries cant be executed outside transaction.In JDBC API, we need to write code for transaction management using commit and rollback.Read more at JDBC Transaction Management.JDBC API throws SQLException that is a checked exception, so we need to write a lot of try catch block code.Most of the times its redundant in every JDBC call and used for transaction management.Hibernate wraps JDBC exceptions and throw JDBCException or Hibernate.Exception un checked exception, so we dont need to write code to handle it.Hibernate built in transaction management removes the usage of try catch blocks.Hibernate Query Language HQL is more object oriented and close to java programming language.For JDBC, we need to write native sql queries.Hibernate supports caching that is better for performance, JDBC queries are not cached hence performance is low.Hibernate provide option through which we can create database tables too, for JDBC tables must exist in the database.Hibernate configuration helps us in using JDBC like connection as well as JNDI Data.Source for connection pool.This is very important feature in enterprise application and completely missing in JDBC API.Hibernate supports JPA annotations, so code is independent of implementation and easily replaceable with other ORM tools.JDBC code is very tightly coupled with the application.Name some important interfaces of Hibernate framework Some of the important interfaces of Hibernate framework are Session.Factory org.Session. Factory Session.Factory is an immutable thread safe cache of compiled mappings for a single database.We need to initialize Session.Factory once and then we can cache and reuse it.Session.Factory instance is used to get the Session objects for database operations.Session org.Session Session is a single threaded, short lived object representing a conversation between the application and the persistent store.It wraps JDBC java.Connection and works as a factory for org.Transaction.We should open session only when its required and close it as soon as we are done using it.Session object is the interface between java application code and hibernate framework and provide methods for CRUD operations.Transaction org.Transaction Transaction is a single threaded, short lived object used by the application to specify atomic units of work.It abstracts the application from the underlying JDBC or JTA transaction.A org.Session might span multiple org.Transaction in some cases.What is hibernate configuration file Hibernate configuration file contains database specific configurations and used to initialize Session.Factory.We provide database credentials or JNDI resource information in the hibernate configuration xml file.Some other important parts of hibernate configuration file is Dialect information, so that hibernate knows the database type and mapping file or class details.What is hibernate mapping file Hibernate mapping file is used to define the entity bean fields and database table column mappings.We know that JPA annotations can be used for mapping but sometimes XML mapping file comes handy when we are using third party classes and we cant use annotations.Name some important annotations used for Hibernate mapping Hibernate supports JPA annotations and it has some other annotations in org.Some of the important JPA and hibernate annotations used are javax.Entity Used with model classes to specify that they are entity beans.Table Used with entity beans to define the corresponding table name in database.Access Used to define the access type, either field or property.Default value is field and if you want hibernate to use gettersetter methods then you need to set it to property.Id Used to define the primary key in the entity bean.Embedded. Canon Rebel T4i Software Download there.

work at the lowest level the database and how you work with transactions in an application that is based on native Hibernate, on Java Persistence, and with or without Enterprise Java.Beans.Transactions allow you to set the boundaries of a unit of work an atomic group of operations.They also help you isolate one unit of work from another unit of work in a multiuser application.We talk about concurrency and how you can control concurrent data access in your application with pessimistic and optimistic strategies.Finally, we look at nontransactional data access and when you should work with your database in autocommit mode.Transaction essentials Lets start with some background information.Application functionality requires that several things be done at the same time.For example, when an auction finishes, three different tasks have to be performed by the Caveat.Emptor application 1 Mark the winning highest amount bid.Charge the seller the cost of the auction.Notify the seller and successful bidder.What happens if you cant bill the auction costs because of a failure in the external credit card system The business requirements may state that either all listed actions must succeed or none must succeed.If so, you call these steps collectively a transaction or unit of work.If only one step fails, the whole unit of work must fail.This is known as atomicity, the notion that all operations are executed as an atomic unit.Furthermore, transactions allow multiple users to work concurrently with the same data without compromising the integrity and correctness of the data a particular transaction should not be visible to other concurrently running transactions.Several strategies are important to fully understand this isolation behavior, and well explore them in this topic.Transactions have other important attributes, such as consistency and durability.Consistency means that a transaction works on a consistent set of data a set of data that is hidden from other concurrently running transactions and that is left in a clean and consistent state after the transactions completes.Your database integrity rules guarantee consistency.You also want correctness of a transaction.For example, the business rules dictate that the seller is charged once, not twice.This is a reasonable assumption, but you may not be able to express it with database constraints.Hence, the correctness of a transaction is the responsibility of the application, whereas consistency is the responsibility of the database.Durability means that once a transaction completes, all changes made during that transaction become persistent and arent lost even if the system subsequently fails.Together, these transaction attributes are known as the ACID criteria.Database transactions have to be short.A single transaction usually involves only a single batch of database operations.In practice, you also need a concept that allows you to have long running conversations, where an atomic group of database operations occur in not one but several batches.Conversations allow the user of your application to have think time, while still guaranteeing atomic, isolated, and consistent behavior.Now that weve defined our terms, we can talk about transaction demarcation and how you can define the boundaries of a unit of work.Database and system transactions Databases implement the notion of a unit of work as a database transaction.A database transaction groups data access operationsthat is, SQL operations.All SQL statements execute inside a transaction there is no way to send an SQL statement to a database outside of a database transaction.A transaction is guaranteed to end in one of two ways Its either completely committed or completely rolled back.Hence, we say database transactions are atomic.In figure 1.To execute all your database operations inside a transaction, you have to mark the boundaries of that unit of work.You must start the transaction and at some point, commit the changes.If an error occurs either while executing operations or when committing the transaction, you have to roll back the transaction to leave the data in a consistent state.This is known as transaction demarcation and, depending on the technique you use, involves more or less manual intervention.Figure 1.Lifecycle of an atomic unit of worka transaction.In general, transaction boundaries that begin and end a transaction can be set either programmatically in application code or declaratively.Download Adobe Flash Player For Samsung Omnia 2 Specifications more.Programmatic transaction demarcation In a nonmanaged environment, the JDBC API is used to mark transaction boundaries.You begin a transaction by calling set.Auto.Commitfalse on a JDBC Connection and end it by calling commit.You may, at any time, force an immediate rollback by calling rollback.In a system that manipulates data in several databases, a particular unit of work involves access to more than one resource.In this case, you cant achieve atomicity with JDBC alone.You need a transaction manager that can handle several resources in one system transaction.Such transaction processing systems expose the Java Transaction API JTA for interaction with the developer.The main API in JTA is the User.Transaction interface with methods to begin and commit a system transaction.Furthermore, programmatic transaction management in a Hibernate application is exposed to the application developer via the Hibernate Transaction interface.You arent forced to use this APIHibernate also lets you begin and end JDBC transactions directly, but this usage is discouraged because it binds your code to direct JDBC.In a Java EE environment or if you installed it along with your Java SE application, a JTA compatible transaction manager is available, so you should call the JTA User.Transaction interface to begin and end a transaction programmatically.However, the Hibernate Transaction interface, as you may have guessed, also works on top of JTA.Well show you all these options and discuss portability concerns in more detail.Programmatic transaction demarcation with Java Persistence also has to work inside and outside of a Java EE application server.Outside of an application server, with plain Java SE, youre dealing with resource local transactions this is what the Entity.Transaction interface is good foryouve seen it in previous topics.Inside an application server, you call the JTA User.Transaction interface to begin and end a transaction.Lets summarize these interfaces and when theyre used java.ConnectionPlain JDBC transaction demarcation with set Auto.Commitfalse, commit, and rollback.It can but shouldnt be used in a Hibernate application, because it binds your application to a plain JDBC environment.TransactionUnified transaction demarcation in Hibernate applications.It works in a nonmanaged plain JDBC environment and also in an application server with JTA as the underlying system transaction service.The main benefit, however, is tight integration with persistence context managementfor example, a Session is flushed automatically when you commit.A persistence context can also have the scope of this transaction useful for conversations see the next topic.Use this API in Java SE if you cant have a JTA compatible transaction service.User.TransactionStandardized interface for programmatic transaction control in Java part of JTA.This should be your primary choice whenever you have a JTA compatible transaction service and want to control transactions programmatically.Entity. |
