![]() “Because they continue to delegitimize themselves and whatever they ultimately release in their findings.”īut Mueller’s mandate when he was first appointed specifically gives him the authority to investigate “ any matters that arose or may arise” directly from the Russia probe. ![]() “If they want to continue to go after non-related financial matters where they’re picking apart associates of the President, then by all means,” Nunberg said. The raid and related criminal investigation are being carried out by the Southern District of New York, but were referred there by Mueller’s team. He also noted the raid on the home, office and hotel room of Michael Cohen, Trump’s longtime personal attorney. Nunberg pointed to the charges Mueller’s team has brought against former Trump campaign chairman Paul Manafort for alleged financial crimes unrelated to his work on the Trump campaign. “They are trying to go after Roger’s finances, to get another ridiculous indictment that has nothing to do with Russia,” said Sam Nunberg, a former Trump campaign aide who worked with Stone on the early stages of Trump’s presidential bid and has been questioned by Mueller’s team as well as the grand jury. The questions about Stone’s finances have some of his allies claiming that Mueller has overstepped his mandate and is simply looking to take down one of the President’s longtime allies. WSJ: Roger Stone tried to get information on Clinton from Assange “I have no intention of being silenced or turning my back on President Trump.” “The special counsel having found no evidence or proof whatsoever of Russian collusion, trafficking in allegedly hacked emails with WikiLeaks or advance knowledge of the publication of (then-Clinton campaign chair John) Podesta’s emails now seems to be combing through every molecule of my existence including my personal life, political activities and business affairs to conjure up some offense to charge me with either to silence me or induce me to testify against the President,” Stone told CNN. Whatever the reasoning, the probe into Stone’s finances should give him cause for concern, Zeldin said. You investigate,” said CNN legal analyst Michael Zeldin, a former assistant to Mueller. “The normal thing for a prosecutor in the course of your investigation is if you come across something that is itself worthy of criminal investigation, you don’t turn a blind eye to it. The interest in Stone’s finances could be tied to Mueller’s charge of investigating Russian meddling in the 2016 election and potential collusion, though another possibility is Mueller is pursuing something unrelated that turned up in the course of the investigation.

Much of the misery caused by the blackouts could have been avoided if gas producers and power plants had winterized their equipment. ![]() In other states like Minnesota, where spot market prices also surged, customers are on the hook for hundreds of millions of dollars since utilities can pass on the additional costs. Texas' legislature has proposed a multi-billion-dollar bailout for utilities that paid exorbitant prices for natural gas and generating capacity. By the time the gas made its way through Texas’ pipeline system and companies marked the product up, it sold for up to $300 per million BTUs, a whopping 100-fold premium over typical prices.įurther Reading Minnesotans furious that they have to pay for Texas’ deep-freeze problemsRatepayers across the country, and in Texas in particular, will be paying for the surge in natural gas prices for years. During the cold snap, one executive discovered a major hub selling gas at $50 per million BTUs, already nearly 17 times the normal price. “You just had the greatest week in the history of the gas market.”įurthermore, Texas’ lightly regulated gas industry doesn’t require public price disclosures, which meant that buyers like power companies and utilities didn’t know whether the deals they were getting were reasonable.īefore the cold snap, natural gas in Texas had been trading at around $3 per million BTUs. “If you’re producing half as much gas as normal but selling at 70 to 100 times the price, then that math is working for you,” one anonymous executive told Bloomberg. But the spot market’s high prices more than made up for the issues. If spot prices hadn’t spiked, gas suppliers would have shared in the pain when producers began shutting down wells. In a statement to Bloomberg, Energy Transfer co-CEO Tom Long blamed the utility’s “miscalculations of the severity of the storm and their lack of competent planning.” The company’s CEO, Paula Gold Williams, has said the pipeline company engaged in “blatant unlawful price gouging” and used the cold snap to “generate more than two years’ worth of profits from intrastate gas sales in just the first quarter of 2021.” CPS is suing Energy Transfer to recoup a portion of the $1 billion it lost during the storm. One utility, CPS Energy, is blaming Energy Transfer for its woes. We’ve reached out to both companies for comment and will update this story if we hear back. Kinder Morgan, another large gas seller in Texas, made $1.41 billion in the first quarter this year compared with a loss of $306 million in the first quarter of 2020. Energy Transfer Partners reported record earnings for the first quarter, securing a profit of $3.29 billion compared with an $855 million loss for the same quarter in 2020. Two major players in the Texas gas pipeline system reaped substantial windfalls from the disaster. As gas supplies tightened, traders and pipeline companies could charge “almost any price they wanted,” power executives told Bloomberg. Gas providers canceled their contracts with utilities and power producers, which had to turn to the volatile spot market to make up the shortfall. By the end of the blackouts, almost half of the state’s natural gas production was offline. After the blackouts began, gas production dropped another 5 billion cubic feet over the next several days as wells still operating lost power. Producers' equipment may not have been winterized, either, and fracking requires massive amounts of water, which can freeze pipes and wells. That was due in part to producers shutting down wells in advance of the cold weather. In the six days before the outages began, daily Texas gas production dropped by nearly 6 billion cubic feet, almost a quarter of the state’s total. In the days leading up to the blackouts, the chair of the Public Utility Commission of Texas spoke with the governor's office 32 times about natural gas curtailments caused by a shortage of supplies.Įarly gas shortages may have been more severe than previously known, according to a new report by BloombergNEF.

PgAdmin is another excellent client that supports all major operating systems and even provides a Dockerized version. To interact with our Postgres database, we can use the command line or clients that come equipped with graphical user interfaces making them easier to use and much faster to navigate.įor Mac OS, I recommend using Postico which is quite simple and intuitive and provides a clean user interface. We will use PostgreSQL (also known as Postgres) to store our data that will be handled and manipulated by our API. In our case, we will build a simple RESTful API and use the Flask-SQLAlchemy extension to connect our API to a Postgres database. Flask with SQLAlchemyįlask is a lightweight micro-framework that is used to build minimal web applications and through third-party libraries, we can tap into its flexibility to build robust and feature-rich web applications. Having introduced the ORM, let us build a simple Flask API that interacts with a Postgres database. Some big names in the industry that rely on SQLAlchemy include Reddit, Yelp, DropBox and Survey Monkey. SQLAlchemy can also be used with Oracle and the Microsoft SQL Server. One good example is Pyscopg which is a PostgreSQL implementation of the DBAPI which when used in conjunction with SQLAlchemy allows us to interact with Postgres databases.įor MySQL databases, the PyMySQL library offers the DBAPI implementation require to interact with them. While SQLAlchemy ORM makes our applications database-agnostic, it is important to note that specific databases will require specific drivers to connect to them. In other words, SQLAlchemy Core provides the means to generate SQL queries. It is also important to note that the SQLAlchemy ORM is built on top of SQLAlchemy Core - which handles the DBAPI integration and implements SQL. The DBAPI was created to establish consistency and portability when it came to database management though we will not need to interact with it directly as SQLAlchemy will be our point of contact. SQLAlchemy wraps around the Python Database API (Python DBAPI) which ships with Python and was created to facilitate the interaction between Python modules and databases. SQLAlchemy is an ORM written in Python to give developers the power and flexibility of SQL, without the hassle of really using it. We also need to be familiar with ORMs and learn them in order to use them more efficiently and this introduces a bit of a learning curve. Through an ORM, the changes we would need to make would be limited to just changing a couple of configuration parameters.Įven though ORMs make our life easier by abstracting the database operations, we need to be careful to not forget what is happening under the hood as this will also guide how we use ORMs. ![]() If our SQL was integrated at multiple points in our application, this will prove to be quite the hassle. Say, if we used SQL in our application to connect to a MySQL database, we would need to modify our code if we were to switch to an MSSQL database since they differ in syntax. ORMs abstract databases from our application, enabling us to use multiple or switch databases with ease. ![]() This eases the process of developing software and reduces the chances of making manual mistakes when writing plain SQL code.Īnother advantage of using ORMs is that they help us write code that adheres to the DRY ( Don't Repeat Yourself) principles by allowing us to use our models to manipulate data instead of writing SQL code every time we need to access the database. That being said, as it's fairly easy to map an object to a database, the reverse is also very simple. In object-oriented programming languages, objects aren't that different from relational entities - they have certain fields/attributes that can be mapped interchangeably. Object-relational mapping, as the name suggests, maps objects to relational entities. In this post, we will delve deeper into ORMs and specifically SQLAlchemy, then use it to build a database-driven web application using the Flask framework. Naturally, as time passed, Object Relational Mappers (ORMs) came to be - which enable us to safely, easily and conveniently connect to our database programmatically without needing to actually run queries to manipulate the data. Though initially done via dedicated SQL tools, we've quickly moved to using SQL from within applications to perform queries. Generally, we use the Structured Query Language (SQL) to perform queries on the database and manipulate the data inside of it. Databases are a crucial part of modern applications since they store the data used to power them. ![]() Not gonna lie, I was expecting so much more for the ending especially since I thought the last volume was really good but this didn't impress me.

In addition to his penchant for holding on to the ball, he also has a nose for the end zone. Since his last fumble, Suggs has rushed 313 times without putting it on the ground. His only fumble came in 1999 on the 14th carry of his redshirt freshman season in Virginia Tech’s 58-20 victory at Rutgers. ![]() Suggs had just one fumble in 327 career carries prior to the Marshall game, not including his 20 carries in the 2000 Gator Bowl, according to the Hokies’ sports information department. As if all the touchdowns weren’t impressive enough, Lee Suggs, Virginia Tech’s senior tailback, was in the midst of a streak that may be considered even more remarkable coming into Thursday night’s game. Leftwich helped the Thundering Herd pick up three quick touchdown in the final 5:38 (on drives of 80, 81 and 80 yards), but the damage was done. Virginia Tech had built a 33-0 lead a minute into the fourth quarter, and the Hokies’ defense was able to sag for the remainder of the game. “People have been making (a big deal) about us since the beginning of the season, so it’s about time we finally got a chance to go out there and prove it,” Suggs said. Virginia Tech had drives of 14 and 15 plays in the second half, capped off by touchdown scoring runs of a yard each by Suggs and Jones. Hand it off to Jones and Suggs and let them milk the clock. The Hokies, who scored on all but two of their possessions, did what they do best in the second half. Marshall drove into Virginia Tech territory two more time in the quarter, but turned the ball over on downs each time when Hokie defensive ends Nathaniel Adibi and Davis got pressure on Leftwich and Virginia Tech’s secondary held their coverages. Three plays after the interception, Jones raced into the end zone to increase Virginia Tech’s lead to 20-0 with 9:11 left before halftime. Early in the second quarter, with Marshall trailing 13-0, Leftwich made his only major mistake of evening when he was intercepted by Hokies linebacker Mikal Baaqee at Marshall’s 47-yard line. Marshall place-kicker Curtis Head had a 22-yard field goal rebound off the back of one of his offensive linemen with the Thundering Herd trailing 3-0 and 7:05 remaining in the first quarter. 16 Marshall (1-1) into third and long situations. It was the third-most passing yards ever surrendered by the Hokies, but Virginia Tech’s defensive front pressured Leftwich in the first half to force No. Leftwich finished 31-of-49 passing for 406 yards, three touchdowns and an interception. Hokies quarterback Bryan Randall, 5-of-12 passing for 101 yards to go along with 36 rushing yards, was erratic in his first start. Virginia Tech’s Kevin Jones and Lee Suggs ran … and ran, and ran, and ran. Other than the lopsided final score, nothing was unexpected about the matchup. Virginia Tech defeated Marshall 47-21 in front of 65,049 fans at Lane Stadium and a national television audience. Leftwich got his numbers, but his team got a thumping. If Marshall quarterback Byron Leftwich was expecting Thursday night’s tussle with Virginia Tech to propel him to the forefront of the Heisman Trophy race, he’d better hope the voters don’t hold the thundering Herd’s shaky defense against him. |
