However, training longer means there is no benefit to doing large-batch training. suggest training longer may help to close the generalization gap. suggest there is a generalization gap in large-batch training. However, large-batch training is difficult.įor example, by using a batch size of 512, AlexNet is able to achieve 80+% top-5 testing accuracy for ImageNet training.Ī straightforward approach may only get 50% ∼ 60% top-5 accuracy or the divergence results when people scale the batch size beyond 4096. All the experiments run the same number of epochs. We use the same setting as the baseline: the first 9/10 of the total epochs used a sequence length of 128 and the last 1/10 of the total epochs used a sequence length of 512. The baseline F1 score is achieved by the pre-trained model (BERT-Large) provided by BERT’s public github (as of February 1st, 2019). Table 1: We use the F1 score of SQuAD-v1 as the accuracy metric. We push the batch size to the memory limit of a TPUv3 pod and can finish BERT training in 76 minutes (Table 1). The baseline BERT-Large model needs 1 million iterations to finish pre-training, while LAMB with batch size 65536/32768 only needs 8599 iterations. LAMB is a general optimizer that works for both small and large batch sizes and does not need hyper-parameter tuning besides the learning rate. To solve this problem, we propose the LAMB optimizer, which helps us to scale the batch size to 65536 without losing accuracy. beyond 8192).īERT pre-training also takes a long time to finish (around three days on 16 TPUv3 chips).

Her hits select theaters on November 20, 2013. Clearly, they make a good time and can’t wait to see what they accomplish with Her. Phoenix once again looks like he’s at the top of his game I just love seeing him in roles like this one.Īnother exciting thing about Her is that Arcade Fire is composing the score! Most know Arcade Fire recorded a version of Wake Up! specifically for Where the Wild Things Are I believe Jonze directed a video for the band as well. It’s great to see Phoenix and Adams reunite, albeit differently than The Master. Her looks simply exquisite, and with a cast like that, I’m ready to pre-order tickets for three showings. Jonze’s last work was the wonderful Where The Wild Things Are, and I was looking forward to see what he would tackle next. I didn’t know much about this project until now.

Returning to narrative filmmaking, Jonze helmed the inspired "Adaptation" (2002), a wildly original, offbeat and entertaining dramedy that confirmed Jonze as a truly visionary filmmaker worthy of the highest accolades. Taking a turn toward the outrageous, he helped create the cult favorite, "Jackass" (MTV, 2000-02), which earned public condemnation for its depiction of dangerous, but hilarious stunts. While keeping his feet firmly planted in the music video world, he ventured into feature films first as an actor in "The Game" (1997) and "Three Kings" (1999), then as a director with the strikingly original "Being John Malkovich" (1999), which earned him an Academy Award nomination for Best Director. Jonze started off as a music video director credited with popular takes on the Beastie Boy's "Sabotage" (1994) and Weezer's "Buddy Holly" (1994), which deftly incorporated a "Happy Days" theme and actual show footage. Throughout his varied career, Spike Jonze quickly established himself as a director whose remarkable vision and prolific output led to creating some of the most memorable films and music videos of his day. As such employees in my industry used it for day-to-day communication as well reducing cost on phone calls. I recommended Zoiper to my industry because it is free, reliable and it worked well on Asterisk (PBX). Well actually it seems I can place calls - just that nobody can hear me and I cannot hear them so obviously they're getting the media path all wrong!!Ĭomments: My industry was facing communication problems, from where an employee will have to move from one block to another. Zoiper cannot deal with a VPN connection on the phone!! If I activate a VPN connection to my office I cannot make or receive any Zoiper calls. Bluetooth volume and integration is just terrible.ħ. Does not automatically put a Zoiper call on hold when answering another call on the native dialer.Ħ. The tiny hold button on the top of the screen changes to an add call button after it is pressed!! There is a HUGE EXPANSE OF UNUSED SCREEN during a call and just little tiny function buttons at the top THAT MOVE AROUND?!?!?ĥ. No floating icon for active calls!! Seriously!! Do you know how next to impossible it is to get back to a call once I've moved on to the home screen or worse - the phone decides to sleep?Ĥ. Huge waste of screen real-estate that could be used to provide easily touchable function buttons instead of the tiny ones at the top of the screen.ģ. This is an expected behavior - one which every native dialer properly does.Ģ. Zoiper will not ring priority callers when the phone is in Do Not Disturb mode. Sadly, this app is a prefect example of inexperienced amateurs or a company that simply couldn't care less about what they put out.ġ. It registers to the PBX and I can assign different ringtones to each registration. Here we are 3+ years later, I have a darn near state of the art phone and Android 10 and while Zoiper kinda works with bluetooth it is still seriously SCREWED UP!! And now it has even more problems than it used to have!! All I can say - unbelievable that they haven't been able to figure out who to produce a decent phone app by now?!?! I am now running it on an LG V40 (Android 10) and overall it registers to the PBX but that is about the extent of it. The double panel to select the on-screen keyboard often leads to confusion because users try to dial a number in the current call but realize (late) that they are using the other keyboard and that for that reason the phone did not answer.Ĭomments: After not using Zoiper for 3+ years i decided to try it again. The poster is a bit annoying because there are times when the program is branded. In the free version for Linux, a previous poster appears that encourages you to buy the PRO version. The program has a very clean and well-designed interface where the user can see the information they need at all times, from the internal number of their account, to the buttons to dial phones and view the history. The Zoiper perfectly completes its main function, which is to be able to make calls from your voip account. It should be noted that the interface is much better than the vast majority of its competitors for Linux. It is a very good softphone type software option and meets the expectations for which it was installed. Comments: The user experience is good in general, except for some small sound problems and depending on the Linux version the program crashes and you have to restart.

The survey also went into 50+ gamers' reasons for playing – having fun, relaxing, and staying mentally sharp were the top three in order – and even what they don't like about games. When the 2019 survey was conducted, Wordle had not yet been released and the word game category was grouped under Trivia and traditional board games, which showed up in the top three genres for just 22% of respondents. While more 50+ gamers in the most recent survey actually spent money on games (38% last year, compared to 27% in 2019), the average amount spent in the six months prior to the survey decreased ($49 last year, compared to $64 in 2019).Īs for what they play, puzzle and logic, card and tile, and word games were the three most popular genres for each age group examined (50-59, 60-69, and 70+), with the popularity of the word game genre receiving a boost from what the AARP calls "The Wordle Effect."ģ6% of gamers 50+ listed word games in their top three favorite genres. Older gamers also skew heavily to mobile platforms, with 84% saying they played on mobile compared to 28% on console and 21% on smart home technology (which includes smart TVs, digital media players, and home assistants).Ĭomputers, laptops, and tablets were lumped together in a separate category, with 53% of respondents saying they played on them as well. The 2022 poll found that average had grown to 12 hours. In the 2019 poll they averaged 8.5 hours a week over the prior six months. There was more noticeable growth in how much time those 50+ gamers spent playing. That's up slightly from the 44% reported in the 2019 version of this survey and more significantly over the 38% who played when the first version of the poll was conducted in 2016. If you are not new to Hearts games start wherever you please! There are hundreds of games available at 247Hearts.The AARP this week released the results of its latest 50-Plus Gamer of Today and Tomorrow survey, providing insight into the growing game playing audience reaching retirement age.Ī survey of nearly 7,800 people conducted last June and July found that 45% of those aged 50 and over played video games at least once a month. As you advance test your skills on Hearts "artificial aficionados" in Medium Hearts, Hard Hearts, and Expert Hearts. If you are a beginner, try your hand against the card players in our Easy Hearts game. Each level of Hearts, Easy, Medium, Hard, and Expert or made more challenging or less so by advances in AI. Players can enjoy Hearts on 247 Hearts with other players because of Artificial Intelligence. All in all there are 26 penalty points in each deal in the card game Hearts. Also, the Queen of Spades or "Calamity Jane" is worth 13 points. In modern day Hearts, unlike Reversis, each Heart is worth one point. Since then this scientific card game has come a long way. It originated in Spain in the 1700's, at that time Heart was called Reversis. The card game, Hearts, has evolved over the years. Whichever player has the LEAST amount of points wins! When a player reaches 100 points, the game will end. Each round of Hearts will end when players have completed their hands. This means a player must play a heart while another suit is being played. A leading trick player is not able to start with a heart unless they only have hearts in their hand or until the hearts have been "broken". The player who takes the trick will become the leader of the next trick. The points accumulated by any penalties and the trick are given to the player of the highest card in the suit that was originally put into play. Among the cards they may choose to discard or "slough" is a penalty Heart or the Queen of Spades. If they do not have a card that is the same suit as the lead card then Heart players can play any card that they have. Subsequent players are to play a card that is the same suit as the lead card. Hearts Card Game is played in a clockwise order. After they have done so the other Heart players will play a card from their hands. Start playing Hearts with the card player with the 2 of clubs starting off the first trick. However, even though the rules are simple there is a righteous range of scientific sport in this "evasion type" card game. Like other fun trick-taking card games such as Spades and Bridge the rules of the game are not complicated. Fall in love with Hearts at ! Hearts is structured to be played with four players, it is not difficult to learn but there is strategic play abound.

With that, we collaborated with John Lynch, Senior Data Engineer, and Flavien Bessede, Data Engineering Manager at Updater to turn the brilliant work they’ve done into this two-part series covering the various approaches, considered limitations, and final output of a team who has put endless thought into building a scalable data architecture at the intersection of dbt and Airflow. In chatting with a handful of Astronomer customers who have spent time exploring solutions at the intersection of Airflow and dbt, we discovered that our friends at Updater have built a particularly great experience for authoring, scheduling, and deploying dbt models to their Airflow environment. Given the complementary strengths of both tools, it’s common to see teams use Airflow to orchestrate and execute dbt models within the context of a broader ELT pipeline that runs on Airflow and exists as a DAG. dbt helps users write, organize, and run these in-warehouse transformations. The portion of the modern data engineering workflow that dbt addresses is significant as ephemeral compute becomes more readily available in the data warehouse itself thanks to tools like Snowflake, data engineers have embraced an ETL->ELT paradigm shift that encourages loading raw data directly into the warehouse and doing transformations on top of the aforementioned ephemeral compute. A tool that often comes up in conversation is dbt, an open-source library for analytics engineering that helps users build interdependent SQL models for in-warehouse data transformation. Editor’s NoteĪt Astronomer, we’re often asked how to integrate Apache Airflow with specialized data tools that accommodate certain usage patterns. Note: All of the code in this post is available in this Github repository and can be run locally using the Astronomer CLI. Tried: /usr/local/ got error: Permission denied: ‘/usr/local/’Īny tip or advice would be really helpful.Streamline your data pipeline workflow and unleash your productivity, without the hassle of managing Airflow. Tried: /usr/local/airflow/dags/ got error: Read-only file system: ‘/usr/local/airflow/dags/’ Tried: /var/local/airlfow got error: Read-only file system: ‘target/partial_parse.msgpack’ I tried different strategies of disabling dbt logs but none of them have worked.ĭbt modules in my implementation are invoked using the bash operator and I am thus looking for a way to circumvent this I tried your advice and tried to write logs into dbt root directory with no success:Ĭmd: [‘bash’, ‘-c’, 'dbt -no-write-json run -profiles-dir /usr/local/airflow/dags/dbt/dbt_profiles -project-dir /usr/local/airflow/dags/dbt/product_health_edp_dbt I too am facing a similar problem when I try running astro airflow in my local environment. Hi and wanted to follow up to see if any of the above strategies worked for you. Read-only file system: 'logs/dbt.log'Ī way around this is to have your dbt root directory in the root astro folder. "Destination": "/usr/local/airflow/dags", "Source": "/host_mnt/Users/alan/projects/astro/dags", dbt will attempt to create a directory in the dags directory.ĭue to the way the dags directory in your local deployment is mounted, Docker will not allow for any user in the container to write to a mounted directory.Īs you can see, the mounted directory is read only (“ro”). When you execute dbt run, it will try to create a logs directory in the dbt root directory. However, the local deployment, spun up by astro CLI, mounts the dags directory from your local machine to the containers. Usually, in a deployment that is not your local deployment started by astro CLI, this works. This is because your dbt project home is set in the dags directory. Flight training is classified into two types: integrated and modular. The cost of becoming a pilot varies according to the type of training you receive and the organization you choose. However, as a rough guide, you can expect to pay somewhere in the region of €80,000-€100,000 to complete your training and obtain your commercial pilot’s licence. How Much Does It Cost To Become A Pilot In The Netherlands?Ĭredit: There is no definitive answer to this question as the cost of becoming a pilot in the Netherlands can vary depending on a number of factors, such as the type of training you undertake and the airline you eventually hope to fly for. The age of an aircraft does not always correlate with safety ask the flight school about their aircraft maintenance department for more information. What time do you have to choose from for free time? Each flight school’s costs vary depending on where it is located, the number of students, and the type of aircraft it flies. Enrolling in an airline pilot training program, where you will be employed by the airlines that have designed it, is a good option as well. If you decide to go abroad for your flight training, you must convert your license to the Netherlands Directorate of Civil Aviation. There are approximately ten flight schools in the Netherlands where you can learn to fly. A minimum of 1 500 hours of flight time in an airplane is required to obtain an ATPL. The ATPL is the most advanced level of the Aircraft Pilot Certificate, which allows you to command air carriers as a pilot. It is critical to have the instrument ratings in order to fly in any weather condition. To improve your pilot license, you can use both Instrument Rating and Multi Engine Rating. To be considered for the VFR license, applicants must have at least 150 hours of flying time, including a cross-country flight of 540 kilometers (300 miles). To begin flying, you will first need to obtain a commercial pilot’s license. Depending on the goal of the pilot, they must complete one or six different stages of pilot training.Ī private pilot’s license allows him or her to fly alone, with passengers, or with cargo without paying any monetary compensation. Aviation-related college degree programs are a good option if you want to go to college while also receiving flight training. It is also critical to note that the tuition fee varies depending on the school and the course you choose to take. Can you decide on a license that is right for you? If you are unsure of the terms, please submit your questions and our team will assist you. Aviationfly walks you through the process of taking all of the necessary steps. In the Netherlands, it is possible to become a pilot after finishing high school. After completing your training and obtaining your license, you will be able to apply for jobs with airlines or other aviation companies operating in the Netherlands. There are a number of flight schools located throughout the country that offer training programs that meet the requirements of the CAA. In order to become a pilot in the Netherlands, you will need to complete an accredited training program and obtain a pilot’s license from the Dutch Civil Aviation Authority (CAA). Yet, even 15 years later, the final 1977 report to the US Federal Trade Commission (FTC) by the Bureau of Consumer Protection was rather equivocal, at best: In particular, a 1961 study by three bona-fide legends in audiology research-Raymond Carhart, James Jerger, and Donald Dirks-published in two papers described their findings as “remarkably unsuccessful in demonstrating objectively that the hearing impaired derive any significant gain in speech intelligibility from binaural as opposed to monaural hearing aids.” 1,2 However, as Mark Ross later pointed out, the word score tests in this early study were performed in monaural direct orientation, a condition we would now expect to differ least from the binaural scores. Several studies using test methods of that time did not support binaural hearing. Indeed, when looking back, they had some reason for concern. There were some who believed binaural fittings were downright unethical and motivated by profit. This probably added to some “disconnect” between clinical audiology and practical dispensing. Additionally, prior to 1978, the role of the audiologist was to test and recommend hearing aids, but not dispense the devices. It should be acknowledged that monaural eyeglass aids were a very popular style in the 1960s, and may have complicated the debate. Figure 1 shows that fewer than one-quarter of all US hearing aids fit prior to 1980 were binaural, and controversies swirled around the benefit of binaural fittings well into the late-70s. However, the road to this particular “best practice”-with probably around 85% of all of today’s fittings involving two hearing aids-was not a smooth one in the United States. Act 1: Challenges and Questions about Binaural Benefitīinaural hearing aid fittings have completely changed the hearing healthcare landscape for the better. Percentage of binaural (in red) versus monaural hearing aid fittings (in blue) from 1975 to 2016 in the United States, as reported by Hearing Instruments and Hearing Review surveys of hearing care professionals (HCPs). Essentially, it has all (okay, maybe just some!) of the key movie elements found in a science thriller: legendary hearing researchers indicating binaural aids weren’t particularly beneficial leading hearing aid specialists saying they were more legendary researchers and clinicians re-assessing the question and coming to new conclusions-all against a backdrop of finger-pointing and accusations about self-interests and profits, as well as a pivotal ruling by the Supreme Court. If you wanted to produce a movie about a controversy in audiology, then binaural amplification might be the subject with the most plot twists and turns. |
