  • Microsoft “Scroogles” Itself

    ‘Microsoft went through a blogger’s private Hotmail account in order to trace the identity of a source who allegedly leaked trade secrets.’ Bear in mind that the alleged violation which MS allege allows them to read their email was a breach of the terms of service, which also include distribution of content which ‘incites, advocates, or expresses pornography, obscenity, vulgarity, [or] profanity’. So no dirty jokes on Hotmail!

  • Theresa May warns Yahoo that its move to Dublin is a security worry

    Y! is moving to Dublin to evade GCHQ spying on its users. And what is the UK response?

    “There are concerns in the Home Office about how Ripa will apply to Yahoo once it has moved its headquarters to Dublin,” said a Whitehall source. “The home secretary asked to see officials from Yahoo because in Dublin they don’t have equivalent laws to Ripa. This could particularly affect investigations led by Scotland Yard and the national crime agency. They regard this as a very serious issue.”

  • Internet Tolls And The Case For Strong Net Neutrality

    Netflix CEO Reed Hastings blogs about the need for Net Neutrality:

    Interestingly, there is one special case where no-fee interconnection is embraced by the big ISPs — when they are connecting among themselves. They argue this is because roughly the same amount of data comes and goes between their networks. But when we ask them if we too would qualify for no-fee interconnect if we changed our service to upload as much data as we download** — thus filling their upstream networks and nearly doubling our total traffic — there is an uncomfortable silence. That’s because the ISP argument isn’t sensible. Big ISPs aren’t paying money to services like online backup that generate more upstream than downstream traffic. Data direction, in other words, has nothing to do with costs. ISPs around the world are investing in high-speed Internet and most already practice strong net neutrality. With strong net neutrality, new services requiring high-speed Internet can emerge and become popular, spurring even more demand for the lucrative high-speed packages ISPs offer. With strong net neutrality, everyone avoids the kind of brinkmanship over blackouts that plague the cable industry and harms consumers. As the Wall Street Journal chart shows, we’re already getting to the brownout stage. Consumers deserve better.

  • The colossal arrogance of Newsweek’s Bitcoin “scoop” | Ars Technica

    Many aspects of the story already look like a caricature of journalism gone awry. The man Goodman fingered as being worth $400 million or more is just as modest as his house suggests. He’s had a stroke and struggles with other health issues. Unemployed since 2001, he strives to take care of basic needs for himself and his 93-year-old mother, according to a reddit post by his brother Arthur Nakamoto (whom Goodman quoted as calling his brother an “asshole”). If Goodman has mystery evidence supporting the Dorian Nakamoto theory, it should have been revealed days ago. Otherwise, Newsweek and Goodman are delaying an inevitable comeuppance and doubling down on past mistakes. Nakamoto’s multiple denials on the record have changed the dynamic of the story. Standing by the story, at this point, is an attack on him and his credibility. The Dorian Nakamoto story is a “Dewey beats Truman” moment for the Internet age, with all of the hubris and none of the humor. It shouldn’t be allowed to end in the mists of “he said, she said.” Whether or not a lawsuit gets filed, Nakamoto v. Newsweek faces an imminent verdict in the court of public opinion: either the man is lying or the magazine is wrong.

  • Make Your Own 3-D Printer Filament From Old Milk Jugs

    Creating your own 3-D printer filament from old used milk jugs is exponentially cheaper, and uses considerably less energy, than buying new filament, according to new research from Michigan Technological University. […] The savings are really quite impressive — 99 cents on the dollar, in addition to the reduced use of energy. Interestingly (but again not surprisingly), the amount of energy used to ‘recycle’ the old milk jugs yourself is considerably less than that used in recycling such jugs conventionally.

  • No, Nate, brogrammers may not be macho, but that’s not all there is to it

    Great essay on sexism in tech, “brogrammer” culture, “clubhouse chemistry”, outsiders, wierd nerds and exclusion:

    Every group, including the excluded and disadvantaged, create cultural capital and behave in ways that simultaneously create a sense of belonging for them in their existing social circle while also potentially denying them entry into another one, often at the expense of economic capital. It’s easy to see that wearing baggy, sagging pants to a job interview, or having large and visible tattoos in a corporate setting, might limit someone’s access. These are some of the markers of belonging used in social groups that are often denied opportunities. By embracing these markers, members of the group create real barriers to acceptance outside their circle even as they deepen their peer relationships. The group chooses to adopt values that are rejected by the society that’s rejecting them. And that’s what happens to “weird nerd” men as well—they create ways of being that allow for internal bonding against a largely exclusionary backdrop.

    a file system that stores all its data online using storage services like Google Storage, Amazon S3, or OpenStack. S3QL effectively provides a hard disk of dynamic, infinite capacity that can be accessed from any computer with internet access running Linux, FreeBSD or OS-X. S3QL is a standard conforming, full featured UNIX file system that is conceptually indistinguishable from any local file system. Furthermore, S3QL has additional features like compression, encryption, data de-duplication, immutable trees and snapshotting which make it especially suitable for online backup and archival.

  • FM-index

    a compressed full-text substring index based on the Burrows-Wheeler transform, with some similarities to the suffix array. It was created by Paolo Ferragina and Giovanni Manzini,[1] who describe it as an opportunistic data structure as it allows compression of the input text while still permitting fast substring queries. The name stands for ‘Full-text index in Minute space’. It can be used to efficiently find the number of occurrences of a pattern within the compressed text, as well as locate the position of each occurrence. Both the query time and storage space requirements are sublinear with respect to the size of the input data.

  • Why Google Flu Trends Can’t Track the Flu (Yet)

    It’s admittedly hard for outsiders to analyze Google Flu Trends, because the company doesn’t make public the specific search terms it uses as raw data, or the particular algorithm it uses to convert the frequency of these terms into flu assessments. But the researchers did their best to infer the terms by using Google Correlate, a service that allows you to look at the rates of particular search terms over time. When the researchers did this for a variety of flu-related queries over the past few years, they found that a couple key searches (those for flu treatments, and those asking how to differentiate the flu from the cold) tracked more closely with Google Flu Trends’ estimates than with actual flu rates, especially when Google overestimated the prevalence of the ailment. These particular searches, it seems, could be a huge part of the inaccuracy problem. There’s another good reason to suspect this might be the case. In 2011, as part of one of its regular search algorithm tweaks, Google began recommending related search terms for many queries (including listing a search for flu treatments after someone Googled many flu-related terms) and in 2012, the company began providing potential diagnoses in response to symptoms in searches (including listing both “flu” and “cold” after a search that included the phrase “sore throat,” for instance, perhaps prompting a user to search for how to distinguish between the two). These tweaks, the researchers argue, likely artificially drove up the rates of the searches they identified as responsible for Google’s overestimates.

  • Sacked Google worker says staff ratings fixed to fit template

    Allegations of fixing to fit the stack-ranking curve: ‘someone at Google always had to get a low score “of 2.9”, so the unit could match the bell curve. She said senior staff “calibrated” the ratings supplied by line managers to ensure conformity with the template and these calibrations could reduce a line manager’s assessment of an employee, in effect giving them the poisoned score of less than three.’

  • Corporate Tax 2014: Irish Government’s “flawed premise” on Apple’s avoidance

    According to our calculation about €40bn or over 40% of Irish services exports of €90bn in 2012 and related national output, resulted from global tax avoidance schemes. It is true that Ireland gains little from tax cheating but at some point, the US tax system will be reformed and a territorial system where companies are only liable in the US on US profits, would only be viable if there was a disincentive to shift profits to non-tax or low tax countries. The risk for Ireland is that a minimum foreign tax would be introduced that would be greater than the Irish headline rate of 12.5%. It’s also likely that US investment in Ireland would not have been jeopardized if Irish politicians had not been so eager as supplicants to doff the cap. Nevertheless today it would be taboo to admit the reality of participation in massive tax avoidance and the Captain Renaults of Merrion Street will continue with their version of the Dance of the Seven Veils.

  • How the search for flight AF447 used Bayesian inference

    Via jgc, the search for the downed Air France flight was optimized using this technique: ‘Metron’s approach to this search planning problem is rooted in classical Bayesian inference, which allows organization of available data with associated uncertainties and computation of the Probability Distribution Function (PDF) for target location given these data. In following this approach, the first step was to gather the available information about the location of the impact site of the aircraft. This information was sometimes contradictory and filled with ambiguities and uncertainties. Using a Bayesian approach we organized this material into consistent scenarios, quantified the uncertainties with probability distributions, weighted the relative likelihood of each scenario, and performed a simulation to produce a prior PDF for the location of the wreck.’

  • How the NSA Plans to Infect ‘Millions’ of Computers with Malware – The Intercept

    The implants being deployed were once reserved for a few hundred hard-to-reach targets, whose communications could not be monitored through traditional wiretaps. But the documents analyzed by The Intercept show how the NSA has aggressively accelerated its hacking initiatives in the past decade by computerizing some processes previously handled by humans. The automated system – codenamed TURBINE – is designed to “allow the current implant network to scale to large size (millions of implants) by creating a system that does automated control implants by groups instead of individually.” In a top-secret presentation, dated August 2009, the NSA describes a pre-programmed part of the covert infrastructure called the “Expert System,” which is designed to operate “like the brain.”

  • A cautionary tale about building large-scale polyglot systems

    ‘a fucking nightmare’:

    Cascading requires a compilation step, yet since you’re writing Ruby code, you get get none of the benefits of static type checking. It was standard to discover a type issue only after kicking off a job on, oh, 10 EC2 machines, only to have it fail because of a type mismatch. And user code embedded in strings would regularly fail to compile – which you again wouldn’t discover until after your job was running. Each of these were bad individually, together, they were a fucking nightmare. The interaction between the code in strings and the type system was the worst of all possible worlds. No type checking, yet incredibly brittle, finicky and incomprehensible type errors at run time. I will never forget when one of my friends at Etsy was learning Cascading.JRuby and he couldn’t get a type cast to work. I happened to know what would work: a triple cast. You had to cast the value to the type you wanted, not once, not twice, but THREE times.

Stuff like this has been happening all week, and he apparently so far has only sold a single coin of several hundred.

  • Florida cops used IMSI catchers over 200 times without a warrant

    Harris is the leading maker of [IMSI catchers aka “stingrays”] in the U.S., and the ACLU has long suspected that the company has been loaning the devices to police departments throughout the state for product testing and promotional purposes. As the court document notes in the 2008 case, “the Tallahassee Police Department is not the owner of the equipment.” The ACLU now suspects these police departments may have all signed non-disclosure agreements with the vendor and used the agreement to avoid disclosing their use of the equipment to courts. “The police seem to have interpreted the agreement to bar them even from revealing their use of Stingrays to judges, who we usually rely on to provide oversight of police investigations,” the ACLU writes.

  • Care.data is in chaos. It breaks my heart | Ben Goldacre

    There are people in my profession who think they can ignore this problem. Some are murmuring that this mess is like MMR, a public misunderstanding to be corrected with better PR. They are wrong: it’s like nuclear power. Medical data, rarefied and condensed, presents huge power to do good, but it also presents huge risks. When leaked, it cannot be unleaked; when lost, public trust will take decades to regain. This breaks my heart. I love big medical datasets, I work on them in my day job, and I can think of a hundred life-saving uses for better ones. But patients’ medical records contain secrets, and we owe them our highest protection. Where we use them – and we have used them, as researchers, for decades without a leak – this must be done safely, accountably, and transparently. New primary legislation, governing who has access to what, must be written: but that’s not enough. We also need vicious penalties for anyone leaking medical records; and HSCIC needs to regain trust, by releasing all documentation on all past releases, urgently. Care.data needs to work: in medicine, data saves lives.

  • Belkin managed to put their firmware update private key in the distribution

    ‘The firmware updates are encrypted using GPG, which is intended to prevent this issue. Unfortunately, Belkin misuses the GPG asymmetric encryption functionality, forcing it to distribute the firmware-signing key within the WeMo firmware image. Most likely, Belkin intended to use the symmetric encryption with a signature and a shared public key ring. Attackers could leverage the current implementation to easily sign firmware images.’ Using GPG to sign your firmware updates: yay.

    On-the-fly video transcoding during live streaming. They’ve done a great job of this!

    At the beginning of the development of this feature, we entertained the idea to simply pre-transcode all the videos in Dropbox to all possible target devices. Soon enough we realized that this simple approach would be too expensive at our scale, so we decided to build a system that allows us to trigger a transcoding process only upon user request and cache the results for subsequent fetches. This on-demand approach: adapts to heterogeneous devices and network conditions, is relatively cheap (everything is relative at our scale), guarantees low latency startup time.

  • Latest Snowden leak: GCHQ spying on Wikileaks users

    “How could targeting an entire website’s user base be necessary or proportionate?” says Gus Hosein, executive director of the London-based human rights group Privacy International. “These are innocent people who are turned into suspects based on their reading habits. Surely becoming a target of a state’s intelligence and security apparatus should require more than a mere click on a link.” The agency’s covert targeting of WikiLeaks, Hosein adds, call into question the entire legal rationale underpinning the state’s system of surveillance. “We may be tempted to see GCHQ as a rogue agency, ungoverned in its use of unprecedented powers generated by new technologies,” he says. “But GCHQ’s actions are authorized by [government] ministers. The fact that ministers are ordering the monitoring of political interests of Internet users shows a systemic failure in the rule of law.”

But the work was later found to be fraudulent, and Dr. Hwang was fired from his university and convicted of crimes. Despite all that, Dr. Hwang has just been awarded an American patent covering the disputed work, leaving some scientists dumbfounded and providing fodder to critics who say the Patent Office is too lax. “Shocked, that’s all I can say,” said Shoukhrat Mitalipov, a professor at Oregon Health and Science University who appears to have actually accomplished what Dr. Hwang claims to have done. “I thought somebody was kidding, but I guess they were not.” Jeanne F. Loring, a stem cell scientist at the Scripps Research Institute in San Diego, said her first reaction was “You can’t patent something that doesn’t exist.” But, she said, she later realized that “you can.”

    This sounds amazing. I hope it makes it to some kind of “semi-finished”.

    A semi-roguelike game inspired by Jorge Borges, Umberto Eco, Neal Stephenson, Shadow of the Colossus, Europa Universalis and Civilization. Although currently in its early stages, URR aims to explore several philosophical and sociological issues that both arose during the sixteenth and seventeenth century (when the game is approximately set), and in the present day, whilst almost being a deep, complex and highly challenging roguelike. To do this the game seeks to generate realistic world histories, though ones containing a few unusual happenings and anomalous experiences. The traditional roguelike staple of combat will be rare and deadly – whilst these mechanics will be modeled in detail, exploration, trade and diplomacy factors will have just as much effort put into them.

    It is interesting to note that the fake UK network was the only one detected by Verrimus. However, given that IMSI Catchers operate multiple fake towers simultaneously, it is highly likely that one or more Irish networks were also being intercepted. Very often a misconfiguration, such as an incorrect country code, is the only evidence available of an IMSI Catcher being deployed when forensic tools are not being used to look for one.

  • TCP incast vs Riak

    An extremely congested local network segment causes the “TCP incast” throughput collapse problem — packet loss occurs, and TCP throughput collapses as a side effect. So far, this is pretty unsurprising, and anyone designing a service needs to keep bandwidth requirements in mind. However it gets worse with Riak. Due to a bug, this becomes a serious issue for all clients: the Erlang network distribution port buffers fill up in turn, and the Riak KV vnode process (in its entirety) will be descheduled and ‘cannot answer any more queries until the A-to-B network link becomes uncongested.’ This is where EC2’s fully-uncontended-1:1-network compute cluster instances come in handy, btw. ;)

  • Irish Law Society takes a stand for “brand owners IP rights”

    The Law Society will attend a meeting of the Oireachtas Health Committee today to outline its strong opposition to the Government proposals to introduce legislation that will require tobacco products to use plain packaging. The society’s director general Ken Murphy will be its principal representative at the meeting today to discuss its submission on the legislation, and to discuss its concerns that a plain packaging regime will undermine registered trade mark, and design, systems and will amount to an “expropriation of brand owners intellectual property rights’. Speaking ahead of the meeting, Mr Murphy told The Irish Times the views contained in it represent those of the Law Society as a whole, and its 10,000 members, and have been endorsed by the society as a whole, rather than the committee. Mr Murphy also said the purpose of the Law Society submission was not to protect the tobacco industry, rather the wider effect and impact such a law would have on intellectual property rights, trade marks, in other areas. “There is a real concern also that plain packaging in the tobacco industry is just the beginning of a trend that will severely undermine intellectual property owners’ rights in other sectors such as alcohol, soft drinks and fast foods.”
    Judging by some reactions on Twitter, “endorsed by the society as a whole” may be over-egging it a little.

  • British American Tobacco – Plain packaging of tobacco products

    Compare and contrast with the Law Society’s comments:

    We believe we are entitled to use our packs to distinguish our products from those of our competitors. Our brands are our intellectual property which we have created and invested in. Plain packaging would deny us the right to use brands. But also, a brand is also an important tool for consumers. As the British Brands Group has stated  , plain packaging legislation “ignores the crucial role that branding plays in providing consumers with high quality, consistent products they can trust”.

  • Why dispute resolution is hard

    Good stuff (as usual) from Ross Anderson and Stephen Murdoch. ‘Today we release a paper on security protocols and evidence which analyses why dispute resolution mechanisms in electronic systems often don’t work very well. On this blog we’ve noted many many problems with EMV (Chip and PIN), as well as other systems from curfew tags to digital tachographs. Time and again we find that electronic systems are truly awful for courts to deal with. Why? The main reason, we observed, is that their dispute resolution aspects were never properly designed, built and tested. The firms that delivered the main production systems assumed, or hoped, that because some audit data were available, lawyers would be able to use them somehow. As you’d expect, all sorts of things go wrong. We derive some principles, and show how these are also violated by new systems ranging from phone banking through overlay payments to Bitcoin. We also propose some enhancements to the EMV protocol which would make it easier to resolve disputes over Chip and PIN transactions.’

  • Migrating from MongoDB to Cassandra

    Interesting side-effect of using LUKS for full-disk encryption: ‘For every disk read, we were pulling in 3MB of data (RA is sectors, SSZ is sector size, 6144*512=3145728 bytes) into cache. Oops. Not only were we doing tons of extra work, but we were trashing our page cache too. The default for the device-mapper used by LUKS under Ubuntu 12.04LTS is incredibly sub-optimal for database usage, especially our usage of Cassandra (more small random reads vs. large rows). We turned this down to 128 sectors — 64KB.’

    ‘an interesting approach to a common problem, that of securely passing secrets around an infrastructure. It uses GPG signed files under the hood and nicely integrates with both version control systems and S3.’ I like this as an approach to securely distributing secrets across a stack of services during deployment. Check in the file of keys, gpg keygen on the server, and add it to the keyfile’s ACL during deployment. To simplify, shared or pre-generated GPG keys could also be used.

  • “IMSI Catcher” used in London

    ‘One case involved Julian Assange’s current home at the Ecuadorian Embassy in London, where visitors were surprised to receive welcome messages from a Ugandan telephone company. It turned out the messages were coming from a foreign base station device installed on the roof, masquerading as a cell tower for surveillance purposes. Appelbaum suspects the GCHQ simply forgot to reformat the device from an earlier Ugandan operation.’

  • The Spyware That Enables Mobile-Phone Snooping – Bloomberg

    More background on IMSI catchers — looking likely to have been the “government-level technology” used to snoop on the Garda Ombudsman’s offices, particularly given the ‘detection of an unexpected UK 3G network near the GSOC offices’:

    The technology involved is called cellular interception. The active variety of this, the “IMSI catcher,” is a portable device that masquerades as a mobile phone tower. Any phone within range (a mile for a low-grade IMSI catcher; as much as 100 miles for a passive interception device with a very large antenna, such as those used in India) automatically checks to see if the device is a tower operated by its carrier, and the false “tower” indicates that it is. It then logs the phone’s International Mobile Subscriber Identity number — and begins listening in on its calls, texts and data communications. No assistance from any wireless carrier is needed; the phone has been tricked. […] “network extender” devices — personal mobile-phone towers — sold by the carriers themselves, often called femtocells, can be turned into IMSI catchers.

  • Why Mt. Gox is full of shit

    leading Bitcoin exchange “Magic The Gatherine Online Exchange” turns out to suffer from crappy code, surprise:

    why does Mt. Gox experience this issue? They run a custom Bitcoin daemon, with a custom implementation of the Bitcoin protocol. Their implementation, against all advice, does rely on the transaction ID, which makes this attack possible. They have actually been warned about it months ago by gmaxwell, and have apparently decided to ignore this warning. In other words, this is not a vulnerability in the Bitcoin protocol, but an implementation error in Mt. Gox’ custom Bitcoin software.
    The rest of the article is eyeopening, including the MySQL injection vulnerabilities and failure to correctly secure a Prolexic-defended server. https://news.ycombinator.com/item?id=7211286 has some other shocking reports of Bitcoin operators being incompetent, including ‘Bitomat, the incompetent exchange that deleted their own [sole] amazon instance accidentally which contained all their keys, and thus customer funds’. wtfbbq

  • Death by Metadata

    The side-effects of algorithmic false-positives get worse and worse.

    What’s more, he adds, the NSA often locates drone targets by analyzing the activity of a SIM card, rather than the actual content of the calls. Based on his experience, he has come to believe that the drone program amounts to little more than death by unreliable metadata. “People get hung up that there’s a targeted list of people,” he says. “It’s really like we’re targeting a cell phone. We’re not going after people – we’re going after their phones, in the hopes that the person on the other end of that missile is the bad guy.”

  • “A reason to hang him”: how mass surveillance, secret courts, confirmation bias and the FBI can ruin your life – Boing Boing

    This is bananas. Confirmation bias running amok.

    Brandon Mayfield was a US Army veteran and an attorney in Portland, OR. After the 2004 Madrid train bombing, his fingerprint was partially matched to one belonging to one of the suspected bombers, but the match was a poor one. But by this point, the FBI was already convinced they had their man, so they rationalized away the non-matching elements of the print, and set in motion a train of events that led to Mayfield being jailed without charge; his home and office burgled by the FBI; his client-attorney privilege violated; his life upended.

  • QuakeNet IRC Network- Article – PRESS RELEASE: IRC NETWORKS UNDER SYSTEMATIC ATTACK FROM GOVERNMENTS

    QuakeNet are not happy about GCHQ’s DDoS attacks against them.

    Yesterday we learned … that GCHQ, the British intelligence agency, are performing persistent social and technological attacks against IRC networks. These attacks are performed without informing the networks and are targeted at users associated with politically motivated movements such as “Anonymous”. While QuakeNet does not condone or endorse and actively forbids any illegal activity on its servers we encourage discussion on all topics including political and social commentary. It is apparent now that engaging in such topics with an opinion contrary to that of the intelligence agencies is sufficient to make people a target for monitoring, coercion and denial of access to communications platforms. The … documents depict GCHQ operatives engaging in social engineering of IRC users to entrap themselves by encouraging the target to leak details about their location as well as wholesale attacks on the IRC servers hosting the network. These attacks bring down the IRC network entirely affecting every user on the network as well as the company hosting the server. The collateral damage and numbers of innocent people and companies affected by these forms of attack can be huge and it is highly illegal in many jurisdictions including the UK under the Computer Misuse Act.

  • PID controller

    Good to know; this generic anti-flap damping algorithm has a name.

    A proportional-integral-derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems. A PID controller calculates an “error” value as the difference between a measured process variable and a desired setpoint. The controller attempts to minimize the error by adjusting the process control outputs.

    Like many companies, the structure of Yahoo’s business is driven by the needs of the business. There are a number of factors which influence decisions about the locations in which the business operates. To encourage more collaboration and innovation, we’re increasing our headcount in Dublin, thus continuing to bring more Yahoos together in fewer locations. Dublin is already the European home to many of the world’s leading global technology brands and has been a home for Yahoo for over a decade already.

  • Opinion: How can we get over ‘Pantigate’?

    The fact that RTÉ had agreed to pay damages (€80,000 in total, according to reports yesterday) to the ‘injured parties’, only came to light in an email from the [far-right Catholic lobby group Iona Institute] to its members last Tuesday. Given the ramifications of the decision to make any kind of payment – regardless of the amount – both for the TV licence payer and those who voice contrarian opinions, the lack of coverage in print media as soon as the Iona email came to light marked a low point for print journalism in Ireland. Aside from a lead story on the damages printed in this paper last Wednesday and ongoing debate online, the media has been glacially slow with commentary and even reportage of the affair. The debacle has untold ramifications for public life in this country. That many liberal commentators may now baulk at the opportunity to speak and write openly and honestly about homophobia is the most obvious issue here. Most worrying of all, however, is the question that with a referendum on the introduction of gay marriage on the horizon, how can we expect the national broadcaster to facilitate even-handed debate on the subject when they’ve already found themselves cowed before reaching the first hurdle?
