Killexams : Oracle Implementation tricks - BingNews Search results Killexams : Oracle Implementation tricks - BingNews Killexams : Python Web Framework on the JVM

Python, a dynamic object-oriented programming language, has been around for quite some time. In its lifetime there have been many web frameworks to choose from (i.e. Pylons, TurboGears, CherryPy, Zope, Django, etc) making it difficult for developers to make a selection as Ian Bicking pointed out,

For a long, long time (longer than most of those frameworks have existed) people have complained about the proliferation of web frameworks in Python.

Recently Django has picked up steam in the world of Python and Java.

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.

Developed and used over two years by a fast-moving online-news operation, Django was designed to handle two challenges: the intensive deadlines of a newsroom and the stringent requirements of the experienced Web developers who wrote it. It lets you build high-performing, elegant Web applications quickly.

Django focuses on automating as much as possible and adhering to the DRY principle.

On the JVM side there exists Jython,

An implementation of the high-level, dynamic, object-oriented language Python written in 100% Pure Java, and seamlessly integrated with the Java platform. It thus allows you to run Python on any Java platform.

It took nearly 6 years for Jython to go from version 2.1 to 2.2, but in just the last few months Jython has gone through two release candidates and another stable release, currently at 2.2.1. The Jython developers are working hard on producing Jython 2.5 which aims to align Jython with CPython 2.5 and provide a much cleaner and consistent code base.

A side goal of Jython 2.5 is to try to get some CPython frameworks working, especially the web frameworks, for example:

  • Django
  • Pylons
  • TurboGears
  • Twisted

InfoQ recently had the opportunity to interview Jim Baker, a python evangelist and contributor to Django on Jython (DoJ), to find out what is expected and when.

What is the expected release date for Django on Jython?

This year. It's predicated on the next release of Jython. See #2 for that planning. Django in contrast just works, with only minor changes, thanks to a lot of work that many other people did in identifying (minor) Jython incompatibilities. Now most of the problems we have identified actually occur only in testing, where Django makes certain assumptions about Python should run that don't apply to Jython. An example of such an assumption that the hash algorithm is the same for dictionary implementations; because we use Java's (ConcurrentHashMap), this is not the case. However, that's an artifact of the testing process, Django doesn't really care about that. Still, we plan to certify this by passing all the tests (fixed as necessary).

What version of Jython is going to be required?

Jython 2.5 - equivalent to CPython 2.5 (or what is conventionally called Python!) is what we are targeting in the Jython project. This is actually moving very fast. We have a 2.5 compiler that's available for experimental usage, but it's getting more and more robust as we have additional people testing it. This "newcompiler" was initiated by a Google Summer of Code project that I mentored. (Bruce Eckel mentioned this in a

blog post. We in fact hit that mid-September date!) At the Python Conference in mid-March, we will be setting the specific target based on where we are. Tobias and I will also be presenting our paper "A New Compiler for Jython" at PyCon.
With the release, will there be a simpler install? Currently your blog post suggests applying patches, copying files, etc.

There will be a simple install! My reporting was simply to show how close we were in fact to this goal. I also anticipate plugin support in major IDEs like Eclipse or Netbeans, although this will come later.

Is Django trying to be what Rails is for Ruby and Grails is becoming for Groovy?

Django offers comparable functionality to those web app frameworks, with ostensibly a more robust platform. So Django is written to be multithreaded, unlike RoR, which means we don't have to go through a lot of tricks to make it work on the Java platform, such as using multiple classloaders. We currently have database support for PostgreSQL, with some work done also on MySQL. I helped write the Oracle backend for Django. We're also planning to support Java DB (Derby).

Jim also expressed the usefulness of having a preconfigured stack available, to ease the experimentation of using Django on Jython (DoJ),

I'd like to see the following preconfigured stack available for Django on Jython (DoJ): Derby + Tomcat. This should be something that a developer can just access via a plugin from Eclipse or Netbeans or IDE of their choice, which means they can configure Derby and Tomcat directly from the IDE. It also provides an obvious migration path to other containers and databases. Perhaps more importantly, such a setup allows for easy DoJ experimentation, whether that's for someone building a Django app, or also using tuple spaces, rules engines, PDF tools, or other parts of the heavy-lifting infrastructure available on the Java platform. This is where I think DoJ provides true compelling value.

Killexams : Pornhub: Judge rules Visa can be sued in abuse claim

A visa logo on a computer screen

An abuse survivor can sue Visa over videos of her posted to Pornhub, a US court has ruled.

Serena Fleites was 13 in 2014 when, it is alleged, a boyfriend pressured her into making an explicit video which he posted to Pornhub.

Ms Fleites alleges that Visa, by processing revenue from ads, conspired with Pornhub's parent firm MindGeek to make money from videos of her abuse.

Visa had sought to be removed from the case.

Ms Fleites' story has featured in the New York Times article The Children of Pornhub - an article which prompted MindGeek to delete millions of videos and make significant changes to its policies and practice.

Her allegations are summarised in the pre-trial ruling of the Central District Court of California.

Millions of views

The initial explicit video, posted to Pornhub without her knowledge or consent, had 400,000 views by the time she discovered it, Ms Fleites says.

She alleges that after becoming aware of the video, she contacted Mindgeek pretending to be her mother "to inform it that the video qualified as child pornography". A few weeks later it was removed

But the video was downloaded by users and re-uploaded several times, with one of the re-uploads viewed 2.7 million times, she argues.

MindGeek earned advertisement revenue from these re-uploads, it is alleged.

Ms Fleites says her life had "spiralled out of control" - there were several failed suicide attempts and family relationships deteriorated - then while living at a friend's house, an older man introduced her to heroin.

To fund her addiction, while still a child, she created further explicit videos at this man's behest, some of which were uploaded to Pornhub.

"While MindGeek profited from the child porn featuring Plaintiff, Plaintiff was intermittently homeless or living in her car, addicted to heroin, depressed and suicidal, and without the support of her family," Judge Cormac J. Carney's summary of her allegations says.

MindGeek told the BBC that at this point in the case, the court has not yet ruled on the truth of the allegations, and is required to assume all of the plaintiff's allegations are true and accurate.

"When the court can actually consider the facts, we are confident the plaintiff's claims will be dismissed for lack of merit," the company said.

'The tools to complete the crime'

The Judge ruled that, at the current stage of proceedings, "the Court can infer a strong possibility that Visa's network was involved in at least some advertisement transactions relating directly to Plaintiff's videos".

But Visa argued that the "allegation that Visa recognized MindGeek as an authorized merchant and processed payment to its websites does not suggest that Visa agreed to participate in sex trafficking of any kind".

It also argued, according to the judge's account of its position, that a commercial relationship alone does not establish a conspiracy.

But Judge Carney said that, again at this stage of proceedings, "the Court can comfortably infer that Visa intended to help MindGeek monetize child porn from the very fact that Visa continued to provide MindGeek the means to do so and knew MindGeek was indeed doing so.

"Put yet another way, Visa is not alleged to have simply created an incentive to commit a crime, it is alleged to have knowingly provided the tool used to complete a crime".

A spokesperson for Visa told the BBC that it condemned sex trafficking, sexual exploitation and child sexual abuse material.

"This pre-trial ruling is disappointing and mischaracterizes Visa's role and its policies and practices. Visa will not tolerate the use of our network for illegal activity. We continue to believe that Visa is an improper defendant in this case."

Zero tolerance

Last month MindGeek's chief executive officer and chief operating officer resigned.

The senior departures followed further negative press in an article in the magazine the New Yorker, examining among other things the company's moderation policies.

Mindgeek told the BBC that it has:

  • zero tolerance for the posting of illegal content on its platforms

  • banned uploads from anyone who has not submitted government-issued ID that passes third-party verification

  • eliminated the ability to download free content

  • integrated several technological platform and content moderation tools

  • instituted digital fingerprinting of all videos found to be in violation of our Non-Consensual Content and CSAM Policies to help protect against removed videos being reposted

  • expanded its moderation workforce and processes

The company also said that any insinuation that it does not take the elimination of illegal material seriously is "categorically false".

Killexams : Apple Kernel Code Vulnerability Affected All Devices

Another day, another vulnerability. Discovered by [Kevin Backhouse], CVE-2018-4407 is a particularly serious problem because it is present all throughout Apple’s product line, from the Macbook to the Apple Watch. The flaw is in the XNU kernel shared by all of these products.

This is a buffer overflow issue in the error handling for network packets. The kernel is expecting a fixed length of those packets but doesn’t check to prevent writing past the end of the buffer. The fact Apple’s XNU kernel powers all their products is remarkable, but issues like this are a reminder of the potential downside to that approach. Thanks to responsible disclosure, a patch was pushed out in September.

Anatomy of a Buffer Overflow

Buffer overflows aren’t new, but a reminder on what exactly is going on might be in order. In low level languages like C, the software designer is responsible for managing computer memory manually. They allocate memory, tagging a certain number of bytes for a given use. A buffer overflow is when the program writes more bytes into the memory location than are allocated, writing past the intended limit into parts of memory that are likely being used for a different purpose. In short, this overflow is written into memory that can contain other data or even executable code.

With a buffer overflow vulnerability, an attacker can write whatever code they wish to that out-of-bounds memory space, then manipulate the program to jump into that newly written code. This is referred to as arbitrary code execution. [Computerphile] has a great walk-through on buffer overflows and how they lead to code execution.

This Overflow Vulnerabilty Strikes Apple’s XNU Kernel

[Kevin] took the time to explain the issue he found in further depth. The vulnerability stems from the kernel code making an assumption about incoming packets. ICMP error messages are sent automatically in response to various network events. We’re probably most familiar with the “connection refused’ message, indicating a port closed by the firewall. These ICMP packets include the IP header of the packet that triggered the error. The XNU implementation of this process makes the assumption that the incoming packet will always have a header of the correct length, and copies that header into a buffer without first checking the length. A specially crafted packet can have a longer header, and this is the data that overflows the buffer.

Because of the role ICMP plays in communicating network status, a closed firewall isn’t enough to mitigate the attack. Even when sent to a closed port, the vulnerability can still trigger. Aside from updating to a patched OS release, the only mitigation is to run the macOS firewall in what it calls “stealth mode”. This mode doesn’t respond to pings, and more importantly, silently drops packets rather than sending ICMP error responses. This mitigation isn’t possible for watchOS and iOS devices.

The good news about the vulnerability is that a packet, malformed in this way, has little chance of being passed through a router at all. An attacker must be on the same physical network in order to send the malicious packet. The most likely attack vector, then, is the public WiFi at the local coffee shop.

Come back after the break for a demonstration of this attack in action.

So far, the vulnerability is only known to crash machines, as seen above. Because of the nature of the problem, it’s likely that this vulnerability will eventually be turned into a full code execution exploit. [Kevin] informed Apple of the issue privately, and they fixed the issue in September updates of macOS and iOS.

Killexams : The Pi Zero 2 W Is The Most Efficient Pi

Last week we saw the announcement of the new Raspberry Pi Zero 2 W, which is basically an improved quad-core version of the Pi Zero — more comparable in speed to the Pi 3B+, but in the smaller Zero form factor. One remarkable aspect of the board is the Raspberry-designed RP3A0 system-in-package, which includes the four CPUs and 512 MB of RAM all on the same chip. While 512 MB of memory is not extravagant by today’s standards, it’s workable. But this custom chip has a secret: it lets the board run on reasonably low power.

When you’re using a Pi Zero, odds are that you’re making a small project, and maybe even one that’s going to run on batteries. The old Pi Zero was great for these self-contained, probably headless, embedded projects: sipping the milliamps slowly. But the cost was significantly slower computation than its bigger brothers. That’s the gap that the Pi Zero 2 W is trying to fill. Can it pull this trick off? Can it run faster, without burning up the batteries? Raspberry Pi sent Hackaday a review unit that I’ve been running through the paces all weekend. We’ll see some benchmarks, measure the power consumption, and find out how the new board does.

The answer turns out to be a qualified “yes”. If you look at mixed CPU-and-memory tasks, the extra efficiency of the RP3A0 lets the Pi Zero 2 W run faster per watt than any of the other Raspberry boards we tested. Most of the time, it runs almost like a Raspberry Pi 3B+, but uses significantly less power.

Along the way, we found some interesting patterns in Raspberry Pi power usage. Indeed, the clickbait title for this article could be “We Soldered a Resistor Inline with Raspberry Pis, and You Won’t Believe What Happened Next”, only that wouldn’t really be clickbait. How many milliamps do you think a Raspberry Pi 4B draws, when it’s shut down? You’re not going to believe it.

Testing Performance and Power Draw

When it comes to picking a tiny Linux computer to embed in your project, you’ve got a lot more choice today than you did a few years ago. Even if you plan to stay within the comfortable world of the Raspberry Pi computers, you’re looking at the older Pi 3B+, the tiny Pi Zero, the powerhouse Pi 4B in a variety of configurations, and as of last week, the Pi Zero 2 W.

I ran all of the Raspberries through two fairly standard torture tests, all the while connected to a power supply with a 0.100 Ω precision resistor inline, and recorded the voltage drop across the resistor, and thus the current that the computers were drawing. The values here are averaged across 50 seconds by my oscilloscope, which accurately accounts for short spikes in current, while providing a good long-run average. All of the Pis were run headless, connected via WiFi and SSH, with no other wires going in or out other than the USB power. These are therefore minimum figures for WiFi-using Pi — if you run USB peripherals, don’t forget to factor them into your power budget.

Test number one is stress-ng which simply hammers all of the available CPU cores with matrix inversion problems. This is great for heat-stressing computers, but also for testing out their maximum CPU-driven power draw. All of the Pis here have four cores except for the original Pi Zero, which has only one. What you can see here is that as you move up in CPU capability, you burn more electrons. The Pi Zero 2 has four cores, but runs at a stock 1 GHz, while the 3B+ runs at 1.4 GHz and the 4B at 1.5 GHz. More computing, more power.

Test number two is sbc-bench which includes a memory bandwidth test (tinymemtest), a mixed-use CPU benchmark (7-zip), and a test of cryptographic acceleration (OpenSSL). Unfortunately, none of the Raspberry Pis use hardware cryptographic acceleration, so the OpenSSL test ends up being almost identical to the 7-zip test — a test of mixed CPU and memory power — and I’m skipping the results here to save space.

For ease of interpretation, I’m using the sum of the two memory sub-tests as the result for TinyMemBench, and the 7-zip test results are an average of the three runs. For all of these, higher numbers are better: memory written faster and more files zipped. This is where things get interesting.

Looking first at the memory bandwidth scores, the 4B is way out ahead, and the old Pi Zero is bringing up the rear, but the 3B+ and the Zero 2 are basically neck-in-neck. What’s interesting, however, is the power used in the memory test. The Zero 2 W scores significantly better than the 3B+ and the 4B. It’s simply more efficient, although if you divide through to get memory bandwidth per watt of power, the old Pi Zero stands out.

Turn then to the 7-zip test, a proxy for general purpose computing. Here again, the four-core Pis all dramatically outperform the pokey Pi Zero. The Pi 4 is the fastest by far, and with proper cooling it can be pushed to ridiculous performance. But as any of you who’ve worked with Raspberry Pis and batteries know, the larger form-factor Raspberry Pi computers consume a lot more power to get the job done.

But look at the gap between the Pi Zero 2’s performance and the Pi 3B+. They’re very close! And look at the same gap in terms of power used — it’s huge. This right here is the Pi Zero 2’s greatest selling point. Almost 3B+ computational performance while using only marginally more power than the old Pi Zero. If you divide these two results to get a measure of zipped files per watt, which I’m calling computational “grunt” per watt, the Zero 2 is far ahead.

If you’re looking for a replacement for a slow Raspberry Pi Zero in some portable project, it really looks like the Pi Zero 2 fits the bill perfectly.

Idle Current and Zombie Current

Some projects only need to do a little bit of work, and then can shut down or slow down during times of inactivity to use less total power over the course of a day. With an eye toward power saving, I had a look at how all of the boards performed when they weren’t doing anything, and here one of the answers was very surprising.

Unless you’re crunching serious numbers or running a busy web server on your Raspberry Pi, chances are that it will be sitting idle most of the time, and that its idle current draw will actually dominate the total power consumption. Here, we can see that the Pi Zero 2 has a lot more in common with the old Pi Zero than with the other two boards. Doing nothing more than keeping WiFi running, the Zeros use less than a third of the power consumed by their bigger siblings. That’s a big deal.

I also wanted to investigate what would happen if you could turn WiFi off, or shut the system down entirely, analogous to power-saving tricks that we use with smaller microcontrollers all the time. To test this, I ran a routine from an idle state that shut the WiFi off, waited 10 seconds, and then shut the system down. I was surprised by two things. One, the power consumed by WiFi in standby isn’t really that significant — you can see it activating periodically during the idle phase.

Second, the current draw of a shut-down system varied dramatically across the boards. I’m calling this current “zombie current” because this is the current drawn by the board when the CPU brain is shut off entirely. To be absolutely certain that I was measuring zombie current correctly, I unplugged the boards about ten seconds after shutdown. These are the traces that you see here, plotted for each system. There are four phases: idle, idle with no WiFi, shut down / zombie, and finally physically pulling the plug.

The Pi 4 draws around 240 mA when it is shut down, or 1.2 W! The Pi 3 draws around 90 mA, or 0.45 W. For comparison, the Pi Zero 2’s idle current is similar to the Pi 3’s zombie current. The Pi Zero 2 has a much-closer-to-negligible 45 mA zombie draw, and the original Pi Zero pulls even less.

The point here is that while it’s not surprising that the power required to idle would increase for the more powerful CPUs, the extent of both the variation in idle and zombie current really dictates which boards to use in a battery powered project. Watch out!

Size and Power Isn’t Everything

In that respect, with the processing power of the Pi 3B, significantly better power management all around, and coming in at half the price, the Raspberry Pi Zero 2 W is incredibly attractive for anything that needs to sip the juice but also needs to pack some punch. The old Pi Zero shined in small, headless projects, and it was the only real choice for battery-driven projects. The Pi Zero 2 definitely looks like a worthy successor, adding a lot more CPU power for not all that much electrical power.

Still, I don’t think that the Pi Zero 2 will replace the 3B+, its closest competitor, for the simple reason that the Pi 3 has more memory and much more versatile connectivity straight out of the box. If your project involves more than a few USB devices, or wired Ethernet, or “normal” HDMI connections, adding all of these extra parts can make a Zero-based setup almost as bulky as a B. And when it comes down to pure grunt, power-budget be damned, the Pi 4 is clearly still the winner.

But by combining four cores tightly with on-chip memory, the Raspberry Pi Zero 2 W is definitely the most energy-efficient Pi.

Killexams : Open Network for Digital Commerce: Govt move could transform e-comm

Online commerce led by large companies like Amazon, SnapDeal, Jio, and Flipkart has posed existential challenges to small retailers. Many of them that lacked the wherewithal to expand their online presence, especially during Covid-19, had to face shrinking sales or had to fold up.

In this context, the pioneering initiative of the government – the Open Network for Digital Commerce (ONDC) aimed at democratising digital commerce, moving away from a platform-centric approach to building an open network, has the potential to dramatically transform e-commerce in India. It would drive retailers to give up functioning in silos and encourage all providers of products and services to join the network, regardless of the platforms they transact on, thus becoming a conduit for innovation and expansion of the e-commerce base.

The implementation of this network would be similar to that of UPI, which has been a major success. The crux of the new initiative is to bring in transparency and make discovery of information that is being created with open network protocols. It would create a level-playing field for all stakeholders and build an inclusive ecosystem for digital commerce.

According to an e-marketer report of December 2021, India holds the fourth place in Asia-Pacific in terms of retail e-commerce sales, after China, Japan and South Korea. India’s online retail market is expected to grow at a CAGR of 19.8% to reach $85.5 billion by 2025, according to a report by Forrester. In 2020, online accounted for 3.6% of India’s total retail sales, with this projected to rise to 6% by 2025.

As per a Redseer report, the number of online buyers from tier-2 and smaller cities will rise from about 78 mn in 2021 to nearly 256 mn by 2026. Hence, the ONDC initiative will be a boon for small retailers who would be servicing customers from small towns in particular. For users, the biggest benefit would be that a comparison of all the available products as well as order placement could be done from the network without having to shift platforms. The ONDC initiative would also help the large players as their customer base would widen and they would be able to access competitive logistics support coverage on the network, thus resulting in speedy deliveries and lower costs for customers.

The ONDC programme aims to bring together 30 mn sellers and 10 mn merchants online, and cover at least 100 cities and towns by August. Critics have pointed out that unlike UPI which is an entirely digital process, ONDC would facilitate a buyer-seller match, which could lead to disputes. Also, the reliability of the seller and the quality of products cannot be guaranteed by the network.

According to equities research firm Jefferies, the entire workflow in the case of UPI is virtual and operates within a controlled environment, whereas in the case of ONDC processes would be stretched over online and offline modes and expectations from offline activities could be subjective and lead to dissatisfaction. Just as UPI offered incremental convenience as a unique value proposition, buyers need to experience a compelling reason to transact through ONDC. If ONDC can repeat the success of UPI, India would be heralding a new phase of e-commerce, an example which other countries may want to emulate eventually.
